The American Academy of Ophthalmology is accredited by the ACCME to provide continuing medical education for physicians. The American Academy of Ophthalmology designates this enduring material for a maximum of 26.25 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity. Overall Meeting Goals Upon completion of this activity, participants will be able to: • Describe recent medical advances in the diagnosis, management, and treatment of conditions encountered in the practice of pediatric ophthalmology and strabismus • Apply improved techniques, compare/contrast methods, and review clinical research and advances in order to provide the best possible treatment options and care to patients • Describe aspects of professionalism that will assist in practice of pediatric ophthlamology and strabismus • Describe new techniques in select aspects of surgery pertinent to pediatric ophthalmology and strabismus Specific Learning Objectives 1. Cite most recent data from randomized controlled clinical trials in the diagnosis and management of amblyopia. 2. Describe new preoperative evaluation techniques and surgical strategies to improve outcomes in patients with comitant, non-paretic strabismus. 3. Compare new surgical techniques for complicated strabismus (restrictive, paretic, miswiring syndromes, scarring, incomitance, etc) to decrease reoperation rate. 4. Outline up-to-date patient selection criteria to identify children undergoing cataract surgery who should receive intraocular lenses. 5. Recognize new treatment techniques for pediatric glaucoma, retinal, and oculoplastic and orbital disease and make appropriate sub-subspecialty referrals for such cases. 6. Describe new treatment strategies to decrease the incidence of significant visual loss from high risk ROP. 7. Recognize pediatric ophthalmic disease of neurologic origin and describe the process for appropriate referrals to pediatric neurology. 8. Utilize the latest resources for discussion of visual development, epidemiology of pediatric eye disease, learning disabilities, vision screening strategies with other physicians and members of the lay community. 9. Identify current coding rules and regulations for pediatric eye diseases. 10. Recognize current laboratory research with potential translation applicability to pediatric ophthalmology.

Due to the nature of the subspecialty, the largest component of AAPOS’ educational program focuses on strabismus, amblyopia, visual development and binocular function. However, the content also emphasizes the other Practice Emphasis Areas (PEAs) that have been defined by the American Board of Ophthalmology (ABO) for their Maintenance of Certification (MOC) process with emphasis on these disease processes in children, and adults with strabismus and eye movement disorders. These include: • • • • • • • • Cataract and Anterior Segment Cornea and External Disease Glaucoma Neuro-ophthalmology and Orbit Oculoplastics and Orbit Refractive Management and Intervention Retina and Vitreous Uveitis Additionally, AAPOS’ educational program provides content for topics such as effective management of a pediatric ophthalmology practice, medical ethics, risk management, and other areas deemed relevant by the needs of the membership. Types of educational activities provided at the annual AAPOS meeting include: • Didactic lectures • Original research in the form of free papers and posters • In-depth focused workshops and symposia on specific topics • Small-group discussion opportunities with speakers and researchers All meeting content is reviewed by the AAPOS Program Committee and Secretary for Program with respect to education qualify and utility. Members are routinely queried regarding their assessment of quality and content, as well as needs for future meetings, and comments are reviewed by the Program Committee and Board of Directors, with necessary changes incorporated into future programs. The expected result of AAPOS’ educational activities is a broad array of ophthalmic knowledge that contributes to the lifelong learning of members and advances physician performance or competence. Ongoing assessment of the impact of AAPOS’ educational program is important in determining modifications to existing activities and the development of new activities. Specific expected results include increased knowledge across the ophthalmic community, activities designed to increase competence and performance with evidence-based standards, current practices, and methods of diagnosis, therapies, and disease prevention. 6 42nd Annual Frank D. Costenbader Lecturer Decisions for Children with Glaucoma David S. Walton, MD Thursday, March 26, 2015 - 8:20 - 8:45 am The Costenbader Lecture is supported by the Children’s Eye Foundation David Walton has devoted his career to improving care and outcomes for children with glaucoma. He grew up in Brigantine, New Jersey, where he was shown both the skill of boat racing and humanity in being a meaningful physician by Dr. Robison Harley. The young Dr. Walton studied engineering at Haverford College, and then came south to study medicine at Duke Medical Center. After residency in pediatrics at Boston’s Children’s Hospital Medical Center, Dr. Walton served in the US Marine Corps and Navy Medical Corps, before continuing on to Ophthalmology (MEEI) residency and Glaucoma fellowship at Massachusetts Eye and Ear Infirmary. Board certified in both pediatrics and ophthalmology, Dr. Walton joined the faculty at MEEI, where he mentored and inspired countless trainees, while pursuing clinical care and research related to childhood glaucoma. Dr. Walton rose to the rank of Clinical Professor of Ophthalmology at Harvard Medical School, and has served Ophthalmology and Pediatric Ophthalmology and Glaucoma both nationally and internationally. A few examples include Program Chair for AAPOS, President of the Chandler Grant Society, and Section Editor for the Journal of Pediatric Ophthalmology and Strabismus. Awards have included Senior Achievement Award from the American Academy of Ophthalmology and International Service award from Rofeh International. He has authored more than 100 peer reviewed papers and chapters, many of them greatly advancing our understanding of glaucoma in children. He early on presented a comprehensive framework for classification of childhood glaucomas, which he has refined and expanded over decades of careful personal experience and observation. He established and is President of the Children’s Glaucoma Foundation, dedicated to supporting programs that benefit children with glaucoma. Above all, Dr. Walton’s generosity toward patients, mentees, and colleagues is under-recognized but truly legend, known only to those of us who have been recipients of this bounty. Dr. Walton is a master clinician and surgeon, an inspirational mentor, and easily the world’s leading expert on childhood glaucoma. He is also certainly the most humble. 7 The Frank D. Costenbader Lecture The Frank D. Costenbader Lecture was inaugurated in 1974 at the Annual Meeting of the Costenbader Society to honor Dr. Costenbader. The American Association for Pediatric Ophthalmology, later the American Association for Pediatric Ophthalmology and Strabismus was created at this meeting. From its inception, AAPOS undertook to sponsor the Costenbader Lecture as the keynote presentation at its annual meeting. Due to failing health, Dr. Costenbader was unable to attend any of the lectures which honored him. Dr. Costenbader was born and educated in Virginia and was a true Virginia Gentleman. He received his undergraduate education at Hampton-Sydney College, his medical degree from the University of Virginia and completed his residency at the Episcopal Eye, Ear and Throat Hospital in Washington, DC. Dr. Costenbader started practice in 1932 in the depression and began a lifetime commitment to teaching, which set the stage for the tremendous influence he had on ophthalmology when he began to only see children. In 1933, Dr. Costenbader was appointed Instructor in Ophthalmology at Georgetown University and he became Special Lecturer and Conferee there in 1964. He also was on the faculty of George Washington University advancing to the rank of Clinical Professor. He was known for his enormous patience, generous with his time, always offering complete answers to even the weakest questions, and he rarely lost his equanimity. He changed the Children’s Hospital Clinic from one of service only to teaching and clinical care. He committed a full day a week to teaching for many years, spending Tuesday afternoons at Children’s and another half day a week at the Episcopal EET Hospital. In 1946, the Episcopal residents started rotating at Children’s, and he was able to focus his teaching efforts there. Dr. Costenbader is referred to as the Father of Pediatric Ophthalmology. That designation is because of his decision in 1943 to limit his practice to pediatric ophthalmology, and he was the first ophthalmologist to do so. He moved his office to a stately brownstone townhouse on 22nd Street in Washington, DC. His waiting room was referred to as Dr. Costenbader’s living room by many of his young patients because of its small furniture. He had two exam rooms on the first floor, which he used, and there were additional exam rooms on the lower level for his orthoptist, Ms. Dorothy Bair, and associates, fellows and preceptors. It was a center for wonderful patient care and the first real education or training center for pediatric ophthalmology. His exam tools were limited. Dr. Costenbader had a picture of an airplane and a phone on a rotating box at the end of his room and kids would beg to come in and see his airplane and talk to him about it. The patient’s examination chair was a kitchen chair placed on a small wooden platform. When asked why he limited his practice to pediatrics, the first thing Dr. Costenbader would say was that kids are just so much more fun. He also was fascinated with the eye problems of children and at that time, ophthalmologists interested in strabismus were more interested in adults and older children and in cosmetic alignment. Dr. Costenbader was an advocate for children. His concern for their health and the financial welfare of families in providing for the health of their children led him to establish and financially support the Eye Fund at Children’s Hospital to pay for indigent patient surgery. This fund is now used to support the training program at the Children’s National Medical Center in Washington, DC. Continuing with his concern for providing for children’s health care, he was co-founder of the Medical Service Plan (today Blue Shield) of the District of Columbia and was the first president from 1946 to 1951. He remained on the board for many years. In addition, he started having parents be with their child in the anesthesia induction room before surgery, he eliminated bandages on eyes following strabismus surgery, and he changed strabismus surgery from two inpatient nights to same-day surgery. Dr. Costenbader was Chief of Ophthalmology at Children’s Hospital of Washington, DC, now The Children’s National Medical Center from 1938 to 1965. He had a remarkable effect on children’s eye care and children’s health in general. This lecture memorializes the man who had the foresight and the courage to begin a subspecialty in ophthalmology and the talent and dedication to train and mold the next generation according to his ideals.

Edward Wilson, MD John F. O’Neill, MD 2015 Leonard Apt Lecturer How the Ground is Shifting in Child Abuse Alex V. Levin, MD, MHSc, FAAP, FAAO, FRCSC Saturday, March 28, 2015 - 8:35 – 8:55 am After graduating from Muhlenberg College in Allentown, Pennsylvania and Jefferson Medical College in Philadelphia, Dr. Levin completed a pediatric residency at Children’s Hospital of Philadelphia and continued on at CHOP as a staff child abuse pediatrician before doing an ophthalmology residency at Wills Eye Hospital in Philadelphia. This was followed by a pediatric ophthalmology fellowship at The Hospital for Sick Children in Toronto where he continued as a staff ophthalmologist and Professor in the Departments of Pediatrics, Genetics and Ophthalmology and Vision Science at the University of Toronto for over 16 years where he was also the Director of the Pediatric Ophthalmology Fellowship program. He completed a MHSc in Bioethics at the University of Toronto. At The Hospital for Sick Children he also served from 2002-2008 as a child abuse pediatrician on the SCAN team. In 2008 he relocated back to Philadelphia to become Chief of Pediatric Ophthalmology and Ocular Genetics at Wills Eye Hospital. He is Professor in the Departments of Pediatrics and Ophthalmology at the Sidney Kimmel Medical College of Thomas Jefferson University. Dr. Levin has a long-standing interest in child abuse that has continued as a major clinical and academic focus throughout his career. His research focus has been the pathophysiology and differential diagnosis of retinal hemorrhages. In addition to his clinical studies in this area, he has conducted research on woodpecker, rat and computer models. He has published 217 peer reviewed papers and 146 book chapters. He has given 1150 invited lectures and visiting professorships internationally many of which are on topics related to retinal hemorrhage and child abuse. Much of his published work addresses topics related to child abuse including the American Academy of Ophthalmology Focal Points on the ophthalmic manifestations of child abuse, the AAO policy statement and the American Academy of Pediatrics policy statement on eye examinations in cases of suspected abuse. He is currently the Chair of the International Advisory Board of the National Center on Shaken Baby syndrome and a Charter Member of the Ray E. Helfer Society. Like Dr. Apt, he is one of less than 10 double boarded pediatrician pediatric ophthalmologists worldwide. In 2009 he became a board certified child abuse pediatrician in the inaugural year that those boards were offered. 9 The Leonard Apt Lecture The Leonard Apt Lecture was established and first presented in 2000 by the American Academy of Pediatrics (AAP) Section on Ophthalmology to honor Leonard Apt, MD, for his dedication and contributions in the fields of pediatrics and pediatric ophthalmology. Dr. Apt was born in Philadelphia on June 28, 1922. He entered college at the age of 14 at the University of Pennsylvania, and trained in pediatrics after completing medical school at Jefferson Medical College in Philadelphia. Physicians everywhere will recall the “Apt Test” for detecting gastrointestinal bleeding in newborns, invented by young pediatrician Leonard Apt in 1955. Over the objections of leading physicians of the day who thought that pediatric ophthalmology was conceptually absurd, he then trained in ophthalmology at Harvard, the University of Cincinnati, and the National Institutes of Health. Dr. Apt became the first physician board-certified in both pediatrics and ophthalmology. As the first National Institutes of Health Special Fellow in Pediatric Ophthalmology mentored by Drs. Frank Costenbader and Marshall Parks, he organized the first formal training program for the new specialty. Dr. Apt served as the first Research Fellow in Pediatric Ophthalmology at Wills Eye Hospital. In 1961, at UCLA, Dr. Apt established the first full-time service in pediatric ophthalmology at a United States medical school, predating both the AAP Section on Ophthalmology and AAPOS. For many years, Dr. Apt served as the principal ophthalmology consultant for the AAP. He organized local and national courses on pediatric eye topics and spoke at Annual Meetings of the AAP. Dr. Apt became a founding member of UCLA’s Jules Stein Eye Institute. Every ophthalmologist owes an intellectual debt to Dr. Apt. This towering intellectual figure developed the coating that first enabled the use of synthetic absorbable sutures for ocular surgery. In 1963, Dr. Apt reported on the use of povidone-iodine as a potent, safe antiseptic on the eye and surrounding skin area. It eventually became the preferred method of ophthalmic surgical preparation. In recent years, Dr. Apt and his colleague, Dr. Sherwin Isenberg, used povidone-iodine in developing countries to prevent and treat blinding eye infections in infants and children. Dr. Apt authored more than 300 scientific and medical publications. To his numerous honors from professional societies, Harvard, Jefferson Medical College, and the University of Pennsylvania have recently been added the 2009 UCLA Emeritus Professorship Award, the 2010 AAP Lifetime Achievement Award, and the 2010 Castle Connolly National Physician of the Year Award for Lifetime Achievement. Beyond medicine, Dr. Apt was active as a founder, board member, and a major contributor to the arts, theater, music, humanitites, and sports. His philanthropic gifts to UCLA have created the “Leonard Apt Fellowship in Pediatric Ophthalmology” and the “Leonard Apt Chair in Pediatric Ophthalmology.” Dr. Apt died of natural causes in Santa Monica, California, on February 1, 2013. The Leonard Apt Lecture pays continuing tribute to the late Dr. Leonard Apt not only for his monumental educational and scientific contributions, but also for his pioneering leadership in creation of pediatric ophthalmology as a medical subspecialty.

Costenbader Lecture Decisions for Children with Glaucoma David S. Walton, MD Paper 1 Thursday 8:20 - 8:45 am Introduction. Care for children with glaucoma requires preparation to prepare for challenging clinical decisions. Appropriate use of goniosurgery can be very helpful for children with infantile primary congenital glaucoma, a condition that must be distinguished from other pediatric glaucomas. Methods. The results of goniotomy for a consecutive cohort of 145 patients and 223 eyes with infantile primary congenital glaucoma recognized in the first year of life and followed for more than 6 months following surgery were studied. Related clinical features were also studied for presentation. Results. Complete Success was defined by a sustained postoperative intraocular pressure of less than 23 mmHg. without medications, the absence of significance complications, and no additional glaucoma surgery. Failure was defined by the intraocular pressure and/or by the performance of other glaucoma surgery. Ninety four percent (138/145) children and 96% of eyes (214/223) experienced Complete Success. No surgical complications occurred. Discussion. The pediatric glaucomas are caused by a large number of diverse primary and secondary etiologies. Successful management decisions in managing these challenging glaucomas depends on personal preparation, accurate determination of their etiology, and assessment of the severity of the patient’s glaucoma. Conclusion. Preparation and experience with the pediatric glaucomas are the foundation for appropriate clinical decisions. The reported favorable efficacy of the standard goniotomy procedure for infantile primary congenital glaucoma supports its continued consideration for treatment of this childhood glaucoma.

The Macula in Pediatric Glaucoma: Quantifying the Inner and Outer Layers Via Optical Coherence Tomography Segmentation. Evan Silverstein MD Kim Jiramongkolchai MD Sharon Freedman MD Mays El-Dairi MD Duke University, Durham, NC Introduction: Recent Spectralis (Heidelberg, Germany) spectral domain optical coherence tomography research software can quantify the thickness of each individual retinal layer. There is a suggestion that the macular ganglion cell layer(GCL) and ganglion cell complex may be more sensitive for detecting glaucoma than the peripapillary retinal nerve fiber layer (pRNFL).1,2 Purpose: characterize/compare the thickness of each macular layer among children with glaucoma vs. normals. Methods: Retrospective, IRB-approved study including eyes of children with glaucoma, physiologic cupping, and normals who had optic nerve/macular imaging with Spectralis, excluding high refractive error(±5.00D), retinal or neurologic abnormalities. The average thickness of each of the 7 retinal layers in the macula (central 6 mm), and pRNFL were compared among diagnostic groups. Results: Included were 80 eyes/80 children: 12 juvenile open angle glaucoma(JOAG), 25 primary congenital glaucoma(PCG), 28 physiologic cupping and 15 normals. Eyes with glaucoma had significantly thinner nerve fiber layer(NFL), ganglion cell layer(GCL), inner plexiform layer(IPL), and pRNFL than normals and those with physiologic cupping (mean±SD(microns): 0.82±0.24vs. 1.00±0.12; 0.93±0.22vs. 1.13±0.10; 0.80±0.14vs. 0.91±0.07; 81.59±26.49vs. 102.71±10.01, respectively, p<0.0001 for all). Compared to eyes with PCG, eyes with JOAG had thinner GCL and pRNFL (0.99±0.19vs. 0.80±0.22, p=0.0007; 87.20±25.20vs. 69.92±26.29, p=0.011; respectively). Normals and physiologic cupping were equivalent with all variables tested. Area under receiver operating curve(ROC-AUC) showed higher discrimination ability for GCL than pRNFL(AUC=0.78 vs.0.74, p=0.04, respectively). Discussion: Children with glaucoma have thinning of the 3 innermost retinal layers in the macula. Conclusion: GCL may be more sensitive than pRNFL and NFL for the detection of glaucoma.

The purpose of this study is to describe retinal changes in pediatric glaucomatous and non-glaucomatous optic atrophy (NGOA). Methods: This retrospective study included children age<18yo with either NGOA or glaucoma, who had Spectralis Spectral-Domain Optical Coherence Tomography (Heidelberg, Germany). Vision, intraocular pressure (IOP), cup-to-disc ratio, Retinal Nerve Fiber Layer (RNFL) and macular scans were studied, excluding poor quality scans. Results: Included were 227 eyes (227 children), 76 with NGOA and 151 with glaucoma. Isolated INLC were found in 21/68 eyes with NGOA (5/18 optic neuritis, 11/36 anterior visual pathway tumors, 2/9 papilledema, 3/5 other) and 2/117 eyes with glaucoma (1 uveitis; 1 prior hydrocephalus). Eyes with INLC, compared to those without INLC, had thinner average RNFL (all eyes=52.0 ±4.8 vs. 78.2±1.8µm, p<0.0001/NGOA=49.2±5.16 vs. 68.0±3.3, p=0.0083, respectively) and worse vision (all eyes logMAR=0.65±0.09 vs. 0.33±0.04, p<0.002/NGOA logMAR=0.74±0.12 vs. 0.46+0.30, p=0.003, respectively). Outer retinal changes were present in 8/76 NGOA eyes (1/1 intracranial and retinal vasculitis, 1/2 nerve drusen, 4/13 papilledema, 2/2 infiltrative optic neuropathy) and 34/151 glaucoma eyes (26 prior intraocular surgery, 6 uveitis, 6 primary retinopathy). Discussion: INLC are more frequent in pediatric NGOA than glaucoma; they are associated with worse vision and thinner RNFL. Outer retinal changes were exclusively seen in uveitis, previous intraocular surgery, papilledema, and retinopathy. Conclusion: In children, INLC and/or outer retinal changes without prior history of intraocular surgery or uveitis should prompt further evaluation References: [1] Wolff B, Azar G, Vasseur V, Sahel JA, Vignal C, Mauget-Faysse M.

Paper 4 Thursday 9:04 - 9:11 am Intraocular medulloepithelioma : New observations on clinical features, pathology and genetics Jerry A Shields MD Swathi Kaliki MD Ralph C Eagle MD Carol L Shields MD Wills Eye Hospital 840 Walnut Street, Philadelphia, PA 19107 Introduction: Intraocular medulloepithelioma is an uncommon pediatric ocular tumor in which there is frequent misdiagnosis and misdirected treatment, often resulting in blindness or enucleation of the affected eye. Methods: Chart review of 41 cases seen by the authors with emphasis on clinical features, treatment, and pathology. Results: All patients had a ciliary body mass. Related features include lens notch, iris neovascularization, glaucoma, cataract, lens subluxation, neoplastic cyclitic membrane, intratumoral cysts and rarely extraocular extension. In 2 cases, there was systemic association with pleuropulmonary blastoma, but most patients were not tested for this recently described association. Treatment included enucleation, iridocyclectomy, plaque radiotherapy, or cryotherapy. Histopathology disclosed benign features in 20%, malignant features in 80%, teratoid features in 37 % and nonteratoid in 63%. Tumors classified as malignant had extremely low metastatic potential. Discussion: Medulloepithelioma is a rare intraocular tumor. If diagnosed early enough removal by iridocyclectomy can be successful. However, enucleation is often necessary. Although medulloepithelioma is nonhereditary, there is a recently recognized association with pleuropulmonary blastoma, a rare pediatric tumor on DICER 1 gene in which 35% of patients have other dysplastic or malignant conditions, including rhabdomyosarcoma. Conclusion: Ciliary body medulloepithelioma displays unilateral features that should prompt the clinician to investigate further for this tumor. In some cases, there is an association with pleuropulmonary blastoma. Plaque radiotherapy and iridocyclectomy provide satisfactory tumor control for some smaller tumors, while enucleation is necessary for larger tumors and for smaller tumors that fail to respond to conservative treatments. 28 Extra Ocular Muscles and Stem Cells DAMARIS MAGDALENE Dr. Darilang Mawrie Ms Atul Kumar Mr. Jina Bhattacharyya Dr Bithiah J Grace Dr Sri Sankaradeva Nethralaya, Guwahati- ASSAM INDIA Paper 5 Thursday 9:11 - 9:18 am Introduction: To isolate stem and progenitor cells from extra ocular muscle tissue and compare it with bone marrow derived stem cells. Methods: The Extraocular muscle tissue was obtained from more than 100 patients undergoing strabismus surgery with an average age of 21 years. The tissue was mechanically dissociated and stem cells were isolated by adherence selection. Differentiation was analyzed by addition of specific induction factors and gene expression was analyzed by real time PCR. The statistical significance was determined using SPSS soft ware. Results: The cells were adherent in nature and spindle shaped, could be passaged upto several generations and had a doubling time of 34 hours. The cells were positive for cell surface expression of CD13,CD44,CD49b,CD49e,CD73,CD90,CD105, HLA class I and negative for CD34,CD45,CD104,CD146,CD200 and HLA class II. The EOM cells could be differentiated into adipocytes and osteocytes. The cells also expressed embryonic markers such as SSEA4, and transcription factors OCT4, NANOG and SOX2. The cells had a high expression of NESTIN and differentiated readily into neuronal cells identified by the expression of GFAP,MAP2B and TUBBIIIB. Discussion: Our study shows for the first time that multipotent progenitor cells are present in the human extra-ocular muscle tissues and could be successfully isolated. The presence of multipotential stem cells in the ocular muscle tissue has significant therapeutic implications as they can be differentiated into retinal progenitor cells to treat retinal degeneration. Conclusion: Their superior neuronal differentiation potential and multipotent nature make these cells highly desirable for cell therapy. References: 1.Porter, J.D., Baker, R.

Anterior Segment Optical Coherence Tomography of the Horizontal and Vertical Extraocular Muscles with Measurement of the Insertion to Limbus Distance Matthew S Pihlblad MD Feyza Erenler MD Aman Sharma MD Ajay M Manchandia MD James D Reynolds MD Ross Eye Institute, University at Buffalo, Buffalo, NY Introduction: To assess the possibility of determining the insertion distance from the limbus of horizontal and vertical extraocular muscles (EOM) with the Heidelberg Spectralis anterior segment optical coherence tomography (AS-OCT). Methods: The right eyes of 46 subjects underwent AS-OCT. The horizontal and vertical EOM insertion distances from the limbus were measured in a masked fashion by two pediatric ophthalmologists. The interclass and intraclass correlation coefficients were used for statistical analysis. Results: 42 lateral, 43 medial, 35 inferior, and 40 superior rectus muscles of right eyes of 46 subjects were included. Insertion to limbus measurements: medial rectus – mean 5.7 ± 0.8 mm, range 4.3 - 7.8 mm; lateral rectus – mean 6.8 ± 0.7 mm, range 4.8 - 8.4 mm; inferior rectus – mean 6.0 ± 0.6 mm, range 4.8 - 7.0 mm; superior rectus – mean 6.8 ± 0.6 mm, range 5.5 - 8.1 mm. The intra- and inter-examiner correlation coefficients for medial, lateral, inferior, and superior rectus muscles’ insertion distances to limbus measurements all exceeded 0.75 (excellent correlation). Discussion: The present study is the first to show that the Heidelberg AS-OCT is capable of imaging all four of the rectus muscle insertions, as well as the first AS-OCT to image the superior and inferior rectus insertions. Conclusion: The vertical and horizontal EOMs can be successfully imaged with the Heidelberg AS-OCT, along with the insertion to limbus distance. The insertion to limbus measurements between examiners and on repeat measurements were highly consistent and reproducible. This has implications for the pre-operative procedure planning in previously operated patients. References: 1. Liu X, Wang F, Xiao Y, Ye X, Hou L.

We compared the degree of excyclorotation with severity of V-pattern and studied associated posterior orbital morphology. Methods: Retrospective chart review of patients with Apert, Crouzon and Pfeiffer syndromes seen from 2003-2013 identified 43 patients with available imaging. Inclusion required documentation of one of three patterns: (1) Severe V-pattern with exaggerated hyper-elevation in adduction, inability to elevate the (contralateral) abducted eye past midline, and significant fundus torsion (2) Moderate V-pattern retaining the ability to elevate the abducted eye and modest fundus torsion and (3) Minimal to absent strabismus and fundus torsion. Cyclo-rotation of the rectus muscles was measured in the coronal and quasi-coronal planes. Boney morphology of the posterior orbit was classified as rounded, partially-crescentic, and crescentic based on relative angulation of the greater and lesser wings of the sphenoid. Results: Severe, moderate, and minimal V-pattern strabismus were associated with 15°, 4°, and 1° of excyclorotation, respectively. Posterior orbital morphology was crescentic in 67%, 0% and 0% and partially-crescentic in 17%, 33% and 0% in the severe, moderate, and minimal V-pattern groups, respectively. This crescentic bowing resulted in lateral shift of the superior rectus and infero-medial shift of the lateral rectus establishing excyclorotation at muscle origins. Discussion: Exaggerated V-pattern strabismus is associated with greater excyclorotation that initiates posteriorly, near the orbital apex. Conclusion: Strabismus procedures designed to reverse excyclorotation and remediate Vpattern may have only modest impact on motility given the very posterior origin of this excyclorotation. Paper 8 Thursday 9:32 - 9:39 am Improvements in Binocular Summation after Strabismus Surgery Stacy L Pineles MD, MS Joseph Demer Sherwin Isenberg Eileen Birch Federico Velez Jules Stein Eye Institute, University of California, Los Angeles, Los Angeles, CA Introduction: Binocular summation (BiS), or improvement in vision using binocular vision compared to the better eye alone, is diminished in patients with strabismus. However, it is still not known how strabismus surgery affects BiS. Methods: Ninety-seven subjects recruited within one month before undergoing strabismus surgery underwent high and low contrast visual acuity testing binocularly and monocularly at pre-operative and two month post-operative visits. BiS was calculated for high contrast ETDRS and Sloan low contrast acuity (LCA) charts at 2.5% and 1.25% levels as the difference between the binocular score and that of the better eye. Pre-operative and post-operative values were compared. Results: There was a significant improvement in BiS at the two low contrast levels for all subjects, and for all contrast levels in the 75 patients in whom surgery successfully restored binocular alignment. For LCA, the proportion of subjects with BiS >5 letters post-operatively was almost twice that pre-operatively (16% to 30% and 11% to 21% for 2.5% and 1.25% contrast, respectively). Similarly, the proportion of subjects with binocular inhibition (binocular score worse by at least 5 letters than better eye score) was decreased post-operatively at all contrast levels (from 19% to 9% for 1.25% contrast). Twenty-eight percent of subjects experienced improvement in BiS scores post-operatively at the lowest contrast level. Discussion: BiS scores improved post-operatively in most subjects undergoing strabismus surgery. This occurred most frequently at the lowest contrast level. Conclusion: Improved BiS represents a newly recognized functional benefit from surgical correction of strabismus. References: 1. Pineles SL, Velez FG, Isenberg SJ, et al.

The aim of this investigation is to develop a technology that would minimize post-operative scarring and rehabilitation period Methods: We have developed a surgery technique for outer tissue dissection and eye muscles isolation using high-frequency radio wave knife. This technique allowed to decrease the injury caused to the eye tissues during the surgery. It also allowed for almost bloodless conduction of the surgery as well as extra sterilization of the wound. We have conducted surgeries on 1242 patients with eye movement disorders using this method. The age distribution was from 2 to 17 years-old. The control group consisted of 120 patients operated using traditional technique. We used vicryl 7/0 sutures Results: A significantly smaller post-operative swelling was observed in all cases in the first group. The wound healing time reduced 3-fold, to 3-4 days. Three months later a post-operative scar could not be observed Discussion: Implementation of the described minimal invasive surgery technology allows to achieve high efficiency of the surgery and considerably decrease the injury caused to tissues. It also leads to a bloodless conduction of the surgery as well as additional intra-operative sterilization of the wound Conclusion: Proposed method of minimal invasive strabismus surgery using radio wave technique allows not only to achieve high efficiency of the surgery, but also to decrease the post-operative rehabilitation time Postnatal Serum Insulin-Like Growth Factor I and Retinopathy of Prematurity Anne K Jensen MD Gui-shuang Ying PhD Jiayan Huang MS Graham E Quinn MD MSCE Gil Binenbaum MD MSCE Introduction: Low serum insulin-like growth factor 1 (IGF-1) has been associated with development of severe retinopathy of prematurity (ROP), but no U.S. studies have been reported. We sought to determine the relationship between postnatal serum IGF-1 levels and severe ROP in a racially diverse U.S. cohort. Methods: Prospective observational cohort study of 74 infants with birth weight (BW) <1251g at 3 Philadelphia hospitals. Weekly filter-paper bloodspot IGF-1 assays beginning at 1 week of life through 42 weeks postmenstrual age (PMA) were measured. All infants had a known ROP outcome. Results: The cohort included 20 Caucasian, 45 black, 2 Asian, and 9 other infants; median gestational age (GA) 27.6 weeks (range 23-33); median BW 975g (range 490-1250). During PMA weeks 28 to 33, mean IGF-1 was 20.0 ng/dL(SE 0.52) for no ROP (n=46), 18.0(0.49) for stage 1 or 2 (n=23), and 17.0(0.70) for stage 3 (n=5, 2 lasered) (p=0.003, linear trend). Adjustment for BW and GA, and subgroup analysis for infants with GA>=27 weeks and GA<27 weeks, showed similar results. Discussion: The observed association between IGF and ROP provides the pathophysiological basis for growth-based predictive models, which could improve efficiency of ROP screening. Similar studies might help clarify ROP pathogenesis in world regions where growth-based models perform less well, oxygen supplementation plays more dominant a role, and more mature babies are at risk. Conclusion: Presence and timing of an association between low postnatal serum IGF and ROP in a racially diverse U.S. sample were found to be consistent with European cohorts. 31 Paper 10 Thursday 11:20 - 11:27 am Paper 11 Thursday 11:31 - 11:38 am Validation of WINROP for Detecting High Grade Retinopathy of Prematurity in Colorado Preterm Infants Jennifer L Jung MD Jennifer H Cao MD Anne Lynch MD, MSPH Ashlee Cerda MPH Brandie D Wagner PhD Rebecca S Braverman MD Robert W Enzenauer MD, MPH Jasleen K Singh MD Emily A McCourt MD Children’s Hospital Colorado, University of Colorado Anschutz Medical Campus Aurora, CO Introduction: To validate the web-based (https://winrop.com), algorithm WINROP using serial postnatal weight measurements, in detecting high grade (Type 1 or Type 2) retinopathy of prematurity (ROP) in a Colorado cohort of neonates at high risk for ROP. Methods: The WINROP algorithm was applied to 483 neonates who were screened for ROP from 2008 to 2011. Neonates were classified into categories of alarm (at risk for developing high grade ROP) and no alarm (minimal risk for high grade ROP). The WINROP algorithm was evaluated using sensitivity and specificity. Results: The median gestational age and birth weight at delivery were 28.2 ± 2.2 weeks (range 23.2-31.6 weeks) and 1124.36 ± 355 g (range 385-2325 g), respectively. Alarm occurred in 241 neonates (49.9%) with the median time from birth to alarm of two weeks. WINROP had a sensitivity of 81.8% and specificity of 53.3% for identifying neonates with high-grade ROP. Eight of the 44 neonates with high grade ROP were missed (five with Type 1 and three with Type 2). Discussion: The focus of the WINROP algorithm is the importance of weight gain in the first few weeks of life in predicting ROP. However, the WINROP algorithm missed 8 neonates with high grade ROP in our Colorado cohort. Differences in underlying characteristics of the preterm study populations may explain the discrepancies in the WINROP algorithm. Conclusion: Our results suggest the need for customization of the algorithm to reflect demographic differences in premature neonates at risk for ROP.

Ryan K Wong, MD. Irena Tsui, MD. Charlotte Gore, MD. Shira Robbins, MD. Michael A Puente Jr, MS. David Kauffman, MS. Lingkun Kong, MD. David G Morrison, MD. Emily A McCourt, MD. University of Colorado , Denver, Colorado Introduction: The purpose of this study was to perform a validation of the Colorado Retinopathy of Prematurity screening model (CO-ROP) in a multi-institutional academic setting. The CO-ROP model signals an alarm for ROP examination in an infant with gestational age of less than or equal to 30 weeks, and birth weight less than or equal to 1500 grams, and a net weight gain less than or equal to 650 grams between birth and 1 month of age. Methods: Retrospective review of 1362 infants undergoing retinopathy of prematurity (ROP) examinations at the University of Colorado, University of California Los Angeles, University of California San Diego, Baylor College of Medicine, and Vanderbilt University. Sensitivity and specificity of detecting ROP using CO-ROP and 95% confidence intervals were calculated. Results: The CO-ROP model resulted in a sensitivity of 99.1% (95%CI 97.3-100%) for Type I ROP, 100% (95%CI 89.1-100%) for Type 2 ROP, and 96.8% (95%CI 95.1-98.6%) for all grades of ROP. Implementing the CO-ROP model would have eliminated 290 (21.3%) infants otherwise screened for ROP using 2013 guidelines. One infant with Type 1 ROP was missed. Discussion: Compared to current 2013 screening criteria, the CO-ROP model resulted in improved efficiency, but did miss one infant with Type 1 ROP. Conclusion: The CO-ROP model uses net weight gain to improve ROP screening efficiency. In this multi-institutional study, we have validated the excellent sensitivity and improved specificity of the model when compared to current 2013 screening criteria. 32 Evaluation of Real-Time Video Feed from the Digital Indirect Ophthalmoscope (Keeler) for Telehealth Consultations Tiffany C Ho1,2; Thomas C Lee MD1,2; Ja-Yoon Uni Choe2; Sudha Nallasamy MD1,2 USC Eye Institute, Keck School of Medicine of USC1; The Vision Center at Children’s Hospital Los Angeles2 Los Angeles, California Introduction: To evaluate the validity of using real-time video indirect ophthalmoscopy for telehealth consultations using retinopathy of prematurity (ROP) as a model disease. Methods: An ophthalmologist simultaneously performed and recorded routine ROP screenings on enrolled premature infants (<31 weeks and <1500 grams) using the Keeler digital indirect ophthalmoscope. Examinations were graded as no ROP, mild, Type 1, or Type 2. Masked to clinical findings, another ophthalmologist reviewed and graded live video feed transmitted at 4096 kbps. We compared the sensitivity and specificity of diagnosing ROP via live video clips to the gold standard in-person examination. Results: 145 examinations of individual eyes from 37 babies were included. Median postmenstrual age (PMA) at delivery was 24 weeks (range 23-34), median birth weight 630 grams (range 455-1530), and median PMA at examination 37 weeks (range 3154). Of those infants with any ROP, the sensitivity and specificity was 100% and 72.9%, respectively. For Type 2 or worse ROP, the sensitivity and specificity was 91.67% and 84.7%. For Type 1 ROP, the sensitivity and specificity was 100% and 99.3%. Discussion: Live video feed obtained by the Keeler system may be read with high sensitivity and specificity to detect treatment-requiring ROP. Future studies include reevaluation of stored video clips by both graders 3 months after conclusion of enrollment to assess intra- and inter-physician sensitivity and specificity of diagnosing ROP. Conclusion: Real-time video indirect ophthalmoscopy via the Keeler system may be useful as an adjunct to bedside evaluation and as a training tool for ophthalmologists to diagnose any pediatric retinal disease.

Preferences and Trends in Practices of Premature Infants for Retinopathy of Prematurity (ROP): A Web-based Survey Amanda Way MD1, Swati Agarwal MD2 1 University of Pittsburgh Medical Center, Pittsburgh, PA 2 University of Florida, Gainesville, FL Introduction: The AAP revised the guidelines for treatment and conclusion of premature infants treated with and without anti-VEGF/laser therapy for ROP. However, some practitioners follow infants longer than currently suggested guidelines. We studied preferences and trends in patterns for infants treated with and without antiVEGF/laser therapy for type-1 ROP. Methods: A web-based survey was administered to active members of AAPOS, WSPOS and ASRS. 267 U.S. and international physicians participated. The survey included questions regarding competency in lasers and intravitreal injections, preferences in treatment with anti-VEGF bevacizumab (IVB), laser or dual therapy for type 1 ROP, frequency of follow-up, postmenstrual age (PMA) of conclusion of retinal examination, and incidence of late recurrence or retinal detachment. Results: 45.9% physicians felt competent in performing laser photocoagulation and 26.8% in providing injections. In infants with avascular retina without prethreshold disease or worse ROP, 54.2% continued examination >50 weeks PMA, 23.3% discontinued at 50 weeks PMA, 3.2% preferred prophylactic laser and 5.1% preferred fluorescein angiography and laser prior to concluding exams. 46.3% physicians preferred IVB as primary monotherapy, 37.3% laser, and 16.4% preferred both IVB and laser in type 1 ROP. Of those who preferred IVB monotherapy, 20.4% concluded examination at ≤55 weeks PMA, whereas 79.6% continued evaluation >55 weeks PMA (range = 60 to ≥80 weeks). Of those who preferred both IVB and laser, 50.6% concluded examination at ≤50 weeks PMA, whereas 49.4% continued >50 weeks (range = 55 to ≥80 weeks).15.5% reported recurrence or late stage retinal detachment with IVB monotherapy and 8.8% with dual therapy. Discussion: Treatment preferences and conclusion of examination in ROP infants varies considerably among physicians without and with treatment. Although a longer follow-up is recommended with IVB, our survey reveals examinations beyond 50 weeks PMA in infants with persistant avascular retina without prethreshold disease and even after laser treatment leading to unwarranted retinal examinations for fear of late complications and medical litigations. Conclusion: The survey highlights low competency in providing lasers/injections among physicians, and extensive follow-up examinations. Uniform care in infants with ROP is needed to limit unnecessary examinations, and improve affordable care. References: 1. Fierson WM.

We sought to determine the prevalence and onset of ocular pathology in children with diabetes mellitus(DM), identify risk factors for ocular disease, and recommend a screening regimen for asymptomatic children. Methods: Retrospective consecutive cohort study of children age<18 years with type 1 or 2 DM examined over a 4 year period. Primary outcomes were diabetic retinopathy, cataract, high refractive error, and strabismus. Hemoglobin A1C(HA1C), age at diagnosis and duration of DM were evaluated as risk factors for ocular disease. Results: 370 children (mean age 11.2±3.7 years, range 1-17.5) had 693 examinations, with mean DM duration 5.2±3.7 years (range 0.1-16.2 years), mean HA1C 8.6±1.9 (range 5 to ≥14). No children had diabetic retinopathy (0%, 95%CI 0-1%). 12(3.3%) had cataract, 5 of which required extraction and were identified by decreased vision, not diabetic screening. Youngest age at cataract diagnosis was 7.5 years, 4.5 years after DM diagnosis. 19 had strabismus, only one of which was microvascular paralytic strabismus. 41(11%) had high refractive error. There were no associations between these complications and duration or control of DM. Discussion: Current guidelines recommend annual screenings for retinopathy after age 10. Based on our findings, frequency of examinations during childhood could be decreased, as no children had retinopathy and other complications are identified through existing amblyopia screening. Conclusion: Diabetic retinopathy is extremely rare in children regardless of duration and control of DM. Based upon our study and literature review, screening examinations could begin at age 10 and be continued every 2-3 years until adulthood. Paper 16 Thursday 12:16 - 12:23 pm Over-minus spectacle correction in the management of intermittent exotropia Shivani Sethi MD Noor Ismaeil OCC James Shaffer MS Stephanie L Davidson MD Monte Mills MD Melanie Sulewski Gil Binenbaum MD Children’s Hospital of Philadelphia, Philadelphia, PA Introduction: We sought to determine the effectiveness of prescribing over-minus spectacle correction in the management of intermittent exotropia. Methods: Retrospective consecutive cohort study of children with intermittent exotropia over a 4 year period. Subjects were prescribed glasses with more myopic correction than their full cycloplegic refraction in an effort to manage their deviation by stimulating accommodative convergence. Primary outcomes included control of exodeviation using PEDIG IXT scale (0-5), refractive error change during over-minus therapy, and successful delay of surgery. Results: 34 children met inclusion criteria, mean age 7.4 years (range 2.1-14.8), followup 1.5 years (range 0.2-4), refraction -1.6 D (range 0 to -15), over-minus 1.1D (range 0.5-1.8). Of 26 subjects with control recorded, mean distance-IXT control was 4.2 and 69% had poor control (IXT 4 or 5) at baseline. At latest follow-up, mean control was 3.4 (p=0.02), with 47% showing improvement, and 44% remaining IXT 4-5. Surgery was recommended for 14(41%) children with average IXT 4.7 after a mean of 1.4 years (range 0.3-3.7) of overminus. 20(59%) children continued overminus glasses without surgery through a mean follow-up of 1.4 years(range 0.2-2.6) with an average IXT 2.6. Mean refractive error change was -0.4D/year (range -1.5 to +0.4). Discussion: Overminus glasses improved exotropia control in half of children, with a sustained effect over prolonged follow-up. Surgery was successfully delayed for many children. Myopia progression rate was similar or less than reported for myopic children in studies unrelated to over-minus correction. Conclusion: Over-minus correction can be used to improve control of intermittent exotropia with minimal risk of myopia progression. 34 Comparison of botulinum toxin versus surgery in the treatment of acute-onset, comitant esotropia in children Michael J Wan MD Iason S Mantagos MD Ankoor S Shah MD, PhD Melanie Kazlas MD David G Hunter MD, PhD Boston Children’s Hospital Boston, MA Paper 17 Thursday 12:23 - 12:30 pm Introduction: The purpose of this study was to compare botulinum toxin to strabismus surgery in the treatment of children with acute-onset, comitant esotropia. Methods: Retrospective, comparative, cohort study of children < 10 years of age with acute-onset, comitant esotropia treated at a tertiary-care hospital over a 12-year period. Patients with abnormal neuroimaging or evidence of cranial nerve palsy were excluded. Results: Forty-six patients were included; 13 received botulinum toxin and 33 received strabismus surgery. There were no significant differences between the groups at baseline. The success rate for botulinum toxin versus surgery was similar at 4 months (77% versus 61%, p = 0.49) and final follow-up (77% versus 55%, p = 0.20). The median residual angle of esotropia was similar at 4 months (4 versus 9 prism diopters, p = 0.40) and final follow-up (4 vs 8 prism diopters, p = 0.28). The duration of general anesthesia (5 versus 71 min, p < 0.001) and time in the recovery room (37 versus 93 min, p < 0.001) were significantly less in the botulinum toxin group. There were no serious or permanent complications in any patients. Discussion: Botulinum toxin has comparable effectiveness to surgery in the treatment of acute-onset, comitant esotropia, while reducing the duration of general anesthesia and time in the recovery room. Botulinum toxin can also be administered within days of esotropia onset, thereby reducing the time of disrupted binocularity. Conclusion: Botulinum toxin should be considered as the procedure of choice for children with acute-onset, comitant esotropia. Intraoperative Botulinum Toxin in Large Angle Strabismus Saurabh Jain Mr Shweta S Anand Ms Alistair Jones Mr Royalfree London Hospitals NHS Foundation Trust, London, UK Introduction: The management of large angle strabismus (> 50PD) involves surgery on three or more extraocular muscles. An alternative approach is to use intraoperative botulinum toxin (BTX) as an adjunct to the surgical recess-resect procedure. Our study aim was to determine the effectiveness of BTX in combination with surgical treatment compared to surgical treatment alone for the correction of large-angle horizontal deviations. Methods: We undertook a prospective, randomized case control study over a period of 18 months (August 2012 to February 2014), enrolling all patients with large angle strabismus. Paediatric patients and patients with residual or consecutive squints were excluded. Postoperative outcome was assessed at 2 weeks and 3 months and patients were monitored for immediate and late side effects of BTX. Results: Sixteen patients were included in the study. Eight patients underwent recessresect procedure with or without muscle transposition with 2.5 units of BTX injection into the recessed muscle and 8 patients underwent surgery without BTX injection. In the BTX group, the Mean angle of deviation decreased from the preoperative value of 53.75 PD to 16.87 PD at 6 weeks and 9.62 PD at 3 months. The Non BTX surgical group showed a decrease in the Mean angle of deviation from 50.62 PD to 9.87 PD at 6 weeks and 8.87 PD at 3 months. No side effects were noted in the BTX group. The overall surgical success was satisfactory with all patients having deviations less than or equal to 8PD at 3 months. Discussion: Contrary to expectation, our observation was that intraoperative BTX did not result in an improved surgical outcome. Although some studies have postulated that BTX causes permanent structural changes in the myosin heavy chain composition of the muscle and may influence the peripheral and central nervous system via retrograde axonal transport, we found the effect of BTX to be transient. Conclusion: Administration of intraoperative BTX did not improve surgical outcomes in our cohort of patients with large angle strabismus. References: 1. Khan AO.

Levin, MD, MHSc, FRCSC Purpose/Relevance: As the first double board certified pediatrician pediatric ophthalmologist, Dr. Leonard Apt was a champion of the collaboration between pediatricians and pediatric ophthalmologists. Child abuse, in particular abusive head trauma, is an area that is exemplary in its need for such collaboration. Target Audience: Pediatric Ophthalmologists Current Practice: A robust scientific evidence base supports our understanding of the ophthalmic findings in abusive head trauma. Studies on victims, accidental head injury, diseases with overlapping findings, deceased children, animals, perpetrator confessions, dummy models and finite element analysis all inform us in a remarkably consistent manner. Yet the media and courtroom present forums for alternate theories, in particular with regards to retinal hemorrhages, which have led to the publication of manufactured controversies and poor science, including the advancement of theory that Shaken Baby syndrome does not exist, which ultimately have led to recent disturbing legal decisions, trends which attack well-meaning science-based experienced physicians, and even fear of involvement from some pediatric ophthalmologists. Best Practice: Cross talk between the pediatrician and pediatric ophthalmologist is now more essential than ever. Sharing science, research collaboration and mutual clinical support is necessary to protect children and families through accurate diagnosis and proper prevention efforts. Well informed and prompt pediatric ophthalmology clinical consultation and courtroom testimony is critical. We must stand by our pediatrician colleagues and work together to speak up in the media as well, to combat this misdirected irresponsible attack on our knowledge, experience and training. Expected Outcomes: The attendee will appreciate and pursue increased collaboration with pediatricians in the care of children victims of abusive heal trauma and other forms of child abuse. Format: Didactic presentation using Powerpoint Summary: As the media portrays a manufactured controversy and misunderstanding of the ophthalmic findings of abusive head trauma, and as under educated judges and juries hand down disturbing decisions regarding these cases, pediatric ophthalmologists and pediatricians must work together to ensure accurate diagnosis, correct public messaging and responsible courtroom education.

Paper 20 Saturday 9:00 - 9:07 am Partial Muscle Recession for Small-Angle Vertical Strabismus Catherine S Choi MD Jasleen K Singh MD Steven M Archer MD Kellogg Eye Center Ann Arbor, MI Introduction: There are few reliable treatment options for small vertical deviations in patients who prefer to be spectacle-free. A partial tendon recession procedure is one surgical option, and this study evaluated its effectiveness in correcting small vertical deviations. Methods: This is a retrospective chart review of 52 procedures in 43 patients. Change in vertical deviation in primary position was evaluated, as was prism diopter change per millimeter of partial tendon recession. Separate analyses were performed to compare outcomes in patients with Graves eye disease and those who underwent re-operations on the same muscle. Results: The average preoperative vertical deviation was 4.6 prism diopters (PD) of deviation (SD 2.0 PD) and the average postoperative vertical deviation was 0.04 PD (SD 2.4 PD), p < 0.0001. There was an average of 1.5 prism diopters of change per millimeter of partial tendon recession. 64% of post-operative patients were orthophoric in the overall sample. 60% of Graves patients were orthophoric post-operatively versus 65% of non-Grave’s patients. 29% of the re-operated patients were orthophoric post-operatively versus 69% of non-re-operated patients. Discussion: Preoperative vertical deviation had a more significant correlation with postoperative alignment than did the actual amount of surgical recession. Our results also suggest outcomes in re-operated muscles are less predictable. There was no significant difference in post-operative outcome between patients with Graves disease and those without. Conclusion: In this sample of patients, a partial tendon recession effectively corrected small vertical deviations and is a treatment option to consider in patients who prefer spectacle independence. 36 Brown Syndrome Outcomes: A Forty-Year Retrospective Analysis Scott A Larson Matthew Weed University of Iowa Iowa City, Iowa Paper 21 Saturday 9:07 - 9:14 am Introduction: It has been proposed that Brown syndrome spontaneously and frequently improves or resolves (1,2). We evaluated patient data from the University of Iowa collected over a forty-year period to determine rates of improvement and which factors may be associated with improvement or resolution. Methods: Review of 305 patient charts suspected of having Brown Syndrome seen from 1973 to 2012. Results: 75 patients were included. Mean age at presentation was 11.4 years (3 months to 77 years) with mean follow-up of 3.62 years (0-20.8 years). 14 (19%) had surgical treatment and all showed improvement at the final visit. 42 patients did not have surgery and had at least one follow up visit. Of this group, 5 (12%) improved, 3 (7%) resolved, 2 (5%) worsened and 32 (76%) remained unchanged. The mean initial supraduction deficit was -3.1 and mean final deficit was -3.4 (p=0.24). Surgery on the superior oblique tendon was the most important factor associated with improvement. Discussion: The most consistent measurement that could be used for comparison was grading of supraduction in the affected eye. Many had no misalignment in primary position and up-gaze measurements were not consistently recorded in young patients. Interobserver variably was taken into account in our analysis (3). Brown syndrome improved or resolved in a minority of patients when comparing supraduction deficits. Conclusion: Although Brown syndrome does improve spontaneously, this appears to be less common. Stability is more common than improvement among patients with Brown syndrome that have follow-up in the strabismus clinic at the University of Iowa. References: 1. Wilson ME, Eustis HS, Parks MM.

We now describe performance of the forced torsion traction test in patients with oblique dysfunction and in controls. Methods: We studied 25 patients with oblique dysfunction (9 with presumed congenital superior oblique palsy (SOP) (9 eyes), 10 with presumed acquired SOP (13 eyes), and 6 with Brown syndrome (7 eyes)) and 31 controls (entirely normal forced duction tests and only horizontal muscle surgery (one randomly selected eye from each control, n=31)). After induction of deep general anesthesia, the 12 and 6 o’clock positions at the limbus were marked and a Mendez-ring was aligned with these reference marks. The limbus was grasped with forceps, the eye was maximally excyclorotated and the angle (in degrees) was read. This procedure was repeated for incyclorotation. Results: Eyes with presumed congenital SOP had greater maximal excyclorotation than controls (median 40 vs 30, p=0.003). Maximal excyclorotation in presumed acquired SOP was similar to controls (median 30 vs 30, p=0.13). Eyes with Brown syndrome had lower maximal excyclorotation than controls (median 10 vs 30, p<0.0001). Maximal incyclorotation of presumed congenital SOP, acquired SOP, and Brown syndrome were similar to controls (median 30,30,30 vs 30). Discussion: The forced torsion traction test quantitatively measures oblique muscle tightness and laxity, and differentiates between congenital SOP, Brown syndrome and controls. Conclusion: The forced torsion traction test enables quantitative assessment of superior oblique and inferior oblique tightness and laxity. 37 Paper 22 Saturday 9:14 - 9:21 am Paper 23 Saturday 9:21 - 9:28 am Synergistic Interaction of Inferior Oblique Weakening and Vertical Rectus Recession for Non-Restrictive Vertical Strabismus Melanie Kazlas Charlotte Gore A Sadiq Mohammad Linda R Dagi David G Hunter Children’s Hospital Boston , Harvard Medical School, Boston, Massachusetts Introduction: Few studies have examined outcomes of combined vertical rectus and inferior oblique surgery. In this study we reviewed our experience to determine whether the surgical nomogram should be modified for combined cases. Methods: Retrospective chart review of patients who underwent inferior oblique weakening alone or in combination with an adjustable vertical rectus recession during a 7.5 year period. Patients with prior vertical surgery, restrictive strabismus, dissociated vertical deviation, large horizontal deviation or follow-up <4 weeks were excluded. Main outcome measure was the effect of inferior oblique weakening on calculated versus actual vertical rectus recession dose response. Results: 163 patients met inclusion criteria. 129 had inferior oblique weakening alone and 34 had inferior oblique weakening plus an adjustable vertical rectus recession. The average effect of inferior oblique weakening was 11.7 PD. After taking this into account, the mean residual effect of vertical rectus muscle recession in combined surgery was 4.1 PD/mm (4.2 PD/mm for inferior rectus recession and 3.9 PD/mm for superior rectus recession). Discussion: The mean effect of vertical rectus recession in combination with inferior oblique weakening is larger than the often cited 3 PD/mm effect for vertical rectus recession alone. In procedures combining inferior oblique weakening with vertical rectus muscle recession, the impact on vertical alignment is larger than if the procedures were performed separately. Conclusion: Our study suggests a synergistic effect of combining inferior oblique weakening with vertical rectus recession. Appreciating the power of a dual procedure may prove important when remediating symptomatic vertical deviations with modest vertical fusional amplitudes. References: Morad Y, Weinstock VM, Kraft SP.

Paper 24 Saturday 9:28 - 9:35 am The incidence of torsional diplopia following inferior rectus muscle recession in thyroid eye disease Tara Tae BS Chantel Devould CO Natalie Kerr MD University of Tennessee Health Science Center, Memphis, TN Introduction: The purpose of this study was to investigate the incidence of incyclotorsion following inferior rectus recession (IRc) without nasalward transposition in patients with thyroid eye disease (TED). Prior studies have implicated superior oblique (SO) muscle restriction as the cause of postoperative incylcotorsion following IRc, but nasalward transposition of the IR (to prevent A pattern exotropia) in these reported cases may be the cause of incyclotropic torsional diplopia following inferior rectus muscle recession, rather than SO restriction. Methods: A retrospective chart review of patients with TED who had undergone unilateral or bilateral IRc without horizontal transposition was performed. Charts were reviewed for clinically significant torsional diplopia as well as A pattern exotropia following surgery. Results: Forty-eight patients met inclusion criteria. Incidence of torsional diplopia was 6.3% (3/48) at 2 months postoperatively and 4.2% (2/48) at last exam. Only one patient developed incyclotorsion with A pattern exotropia postoperatively (2.1%). Discussion: The very low incidence of incyclotorsion following IRc without horizontal transposition in TED implicates nasalward transposition of the IRc rather than superior oblique restriction as the most likely etiology of clinically significant postoperative incyclotropia. Also, the low incidence of A pattern exotropia indicates that nasalward transposition is not necessary to prevent this problem. Conclusion: IRc without nasalward transposition has a low risk of postoperative incyclotorison and A pattern exotropia, References: 1. Holmes JM, Hatt SR, Bradley EA.

Kraker, MSPH For the Pediatric Eye Disease Investigator Group Tampa, Florida Introduction: To describe children undergoing lensectomy in the United States and Canada. Methods: A prospective registry of children <13 years of age who underwent lensectomy in the preceding 45 days Results: 552 children were enrolled; 283(51%) were female. Race/ethnicity was 334(61%) white, 77(14%) African American, 79(14%) Hispanic, 15(3%) Asian, 33(6%) mixed/other, and 14(3%) not reported. Age at surgery was <1 year in 176(32%); 1 to <4 in 112 (20%); 4 to <7 in 128 (23%); and 7 to <13 in 136 (25%). Surgery was bilateral in 172 (31%). Medical conditions were reported for 157 (28%), developmental delay in 38 (7%), and Down syndrome in 7 (1%). Healthcare insurance was reported for 540 (98%); 43% had Medicaid/State CHIP. Of the 689 enrolled eyes, abnormalities other than cataract were reported in 169 (25%). An IOL was used for 254 of 380 (67%) unilateral and 97 of 172 (56%) bilateral cases. IOLs were placed in 8% of cases performed prior to 1 year of age, more often with unilateral surgery than bilateral surgery (11% and 5%, respectively). Mean refractive error was +1.34D among 426 eyes with an IOL and +19.03D among 263 aphakic eyes. The mean target refractive error was +1.41D (range -6.00 to +8.00D). The mean absolute value of the IOL prediction error was +1.10D and <1D in 56%. Discussion: About 1 in 4 children undergoing lensectomy had systemic or ocular conditions. Slightly more than half of eyes had an IOL placed.. Conclusion: Use of an IOL was common after 1 year of age for both unilateral and bilateral lensectomy. Moderate prediction error was found. Genetic Testing for Congenital Cataracts Matthew C Weed MD Scott R Lambert MD Scott A Larson MD Richard J Olson MD Susannah Q Longmuir MD Adam P DeLuca PhD Jeaneen L Andorf BA Edwin M Stone MD, PhD Arlene V Drack MD University of Iowa, Iowa City, Iowa Introduction: Congenital cataracts are a major cause of treatable blindness in children worldwide. The large number of causative genes and the autosomal dominant, recessive, and X-linked recessive inheritance patterns make genetic testing complex. We present a strategy for genetic testing of congenital cataracts. Methods: IRB approval was obtained. Congenital cataract patients presenting to two pediatric ophthalmology services were offered research-based genetic testing. Literature review of causative mutations published at least twice was used to develop a Sanger sequencing pre-screen of 24 exons in 11 genes (BFSP2, CRYAA, CRYBA1, CRYBB2, CRYGD, EPHA2, FAM126A, FYCO1, NHS, PAX6 and VSX2). Negative pre-screens received exome sequencing on a lens-related genes panel. Variants were verified by Sanger sequencing. Allele frequency, calculated effect of mutations, and familial segregation were used to impute pathogenicity. Results: Twenty-six probands submitted samples for research-based genetic testing. Pre-screening identified causative variants in 4 families and possible causative variants in 2. 20 probands had exome sequencing performed. 17/20 had protein-altering mutations in one or more lens-related genes. Each proband averaged 1.0 rare variants (range 0-3). Family segregation analysis of variants is underway and must be completed prior to concluding pathogenicity. Disease-causing genes identified on pre-screen included CRYBA1 (1), CRYGD (2) and NHS (1). Possible disease-causing variants are in CRYAA and FYCO1. Discussion: Exome sequencing can be used to simultaneously screen multiple genes for diseasecausing mutations and is useful for a polygenic disease like congenital cataract. Non-disease causing variants are common in humans, however; results must be carefully scrutinized to confirm pathogenicity. A pre-screen test for known, common mutations decreases cost and increases testing efficiency. Conclusion: Congenital cataract genetic testing combining a pre-screen with an exome platform allows clinicians to provide genetic counseling, prognosis, and early differentiation of syndromic from non-syndromic cataract.

Methods: Cataract extraction was performed between 28 and 209 days of age on 114 infants with a unilateral congenital cataract. 57 were randomized to receive an IOL; the remaining 57 were left aphakic. Recognition acuity was assessed at age 4½. Patching was prescribed until age 5. Adherence to prescribed patching was assessed using quarterly telephone interviews and annual patching diaries. Occlusion was the average number of hours of patching reported on at least 3 adherence assessments within 5 age bands: 0-<12 months of age, 12-<24 months, 24-<36 months, 26-<48 months, 48-<60 months. Results: Hours of patching at each time point was correlated with patching at all other time points. Few (n=5) caregivers reported averaging more than 3 hours of patching in years 3-5 if they had not done so in the first 2 years. Patching was strongly correlated with acuity. Correlation coefficients ranged from -0.32 for patching in the 5th year of life to -0.42 for patching in the 2nd year, were similar for pseudophakic and aphakic children, and were not confounded by adverse events, age at surgery, gender, race or type of insurance. Discussion: We affirm the importance of patching to visual acuity in children after unilateral cataract extraction in infancy. Conclusion: Patching in the first years after surgery may be particularly important as caregivers who are able to adhere to patching in infancy are more likely to adhere to prescribed patching later.

This randomized clinical trial is designed to compare the effectiveness of Amblyz™ glasses versus adhesive occlusion patching for treating moderate, unilateral amblyopia in children. Methods: Sixteen children ranging from 3 to 8 years of age with previously untreated, moderate, unilateral amblyopia (visual acuity of 20/40 to 20/80 in the amblyopic eye) were enrolled. All subjects had worn optimal refractive correction for at least 12 weeks without improvement and their amblyopia was associated with strabismus, anisometropia, or both. Subjects were randomized into one of two treatment groups: a 4-hour daily Amblyz™ occlusion glasses group with liquid crystal shutter set at 30-second opaque/transparent intervals, or the 2-hour adhesive patching control group. For each patient, visual acuity was measured with ATS-HOTV methods before and after 12 weeks of treatment. Results: At the conclusion of the first 12 week-treatment interval, visual acuity in the amblyopic eye improved an average of 2.04 lines in the 2-hour adhesive patch group and 2.01 lines in the 4-hour Amblyz™ glasses group. This difference was not statistically significant. Discussion: The apparent effectiveness of Amblyz™ glasses warrants further investigation with longer follow-up and larger sample size. Conclusion: Amblyz™ liquid crystal occlusion glasses appear to be equally effective compared to adhesive occlusion patches when treating 3-8 year old children with moderate unilateral amblyopia. This new device is a promising alternative treatment for amblyopia. References: Spierer, A., et al., Treating amblyopia with liquid crystal glasses: a pilot study.

This study has examined how these deficits evolve with age. Methods: Movements of the child’s preferred hand to pick up cylindrical objects under monocular and binocular viewing conditions were recorded using a 3-D motion capture system. 55 children aged 5 to 9 years with a range of severity of amblyopia and deficient binocular function were studied and compared to 28 control children. Movement dynamics and error rates were analyzed and compared using ANOVA and stepwise regression analysis. Results: When compared to age-matched controls, the movements of 5-6 year-old amblyopic children were both much slower and contained more reach and grasp errors when viewing with either the amblyopic or fellow eye or with both eyes open (all P<0.05; n=30). Slow movements were mainly related to severity of amblyopia, whereas poor or absent stereopsis was the main determinant of high error rates. For the older amblyopic children aged 7-9 absent stereovision was the main determinant of persistent reach and grasp errors (P<0.05; n=25). Discussion: The strategies that children with amblyopia and deficient binocular function use for reach-to-precision grasping change with age from emphasis on visual feed back during approach to an object at ages 5-6 to more reliance on tactile information from object contact aged 7-9 and differ from those of normal children. Conclusion: Loss of stereoscopic vision is the main factor in long-term deficits of eyehand co-ordination in children with strabismus and amblyopia. References: 1.

Binocular Movie Treatment of Amblyopia Improves Visual Acuity in Children Simone L Li PhD Alexandre Reynaud PhD Robert F Hess PhD Yi-Zhong Wang PhD Reed M Jost MS Sarah E Morale BS Angie De La Cruz BS Lori Dao David Stager Jr Eileen E Birch PhD Retina Foundation of the Southwest, Dallas, TX, USA McGill Vision Research, Dept. of Ophthalmology, McGill University, Montréal, Québec, Canada Pediatric Ophthalmology & Adult Strabismus, Plano, TX, USA Dept. of Ophthalmology, UT Southwestern Medical Center, Dallas, TX, USA Introduction: Many amblyopic patients have a structurally intact binocular visual system that can be revealed by decreasing the fellow-eye contrast to reduce the interocular suppression. We previously demonstrated that repeated binocular experience via at-home binocular iPad game play with reduced fellow-eye contrast was effective in treating childhood amblyopia (ref 1 & 2) and that visual acuity was maintained ≥12 months (ref 3). However, compliance was low in 32-38% of children, primarily due to lack of interest in the games (ref 1 & 2). Here we investigate the effectiveness of a potentially more engaging movie method to provide regular binocular experience via complementary dichoptic stimulation as a treatment for amblyopia. Methods: Six amblyopic children (4-10y; 0.4-0.8 logMAR or 20/50-20/125) were invited to watch 3 dichoptic movies per week for 2 weeks. Dichoptic versions of 18 popular animated feature films were created, with a dynamic reduced contrast texture in the fellow eye. Movies were displayed on a passive 3D display. Initial fellow eye contrast was set based on the child’s dichoptic motion coherence threshold, and incremented by 10% at each visit. At baseline, 1- and 2-week visits, best-corrected visual acuity (BCVA) was measured. Results: After watching 6 dichoptic movies during a two-week period (9.0±1.1 hours), mean (±SE) amblyopic eye BCVA improved from 0.58±0.07 logMAR at baseline to 0.42±0.04 logMAR (p=0.03); i.e., 0.17 logMAR or 1.7 lines. Four children with 0.4-0.5 logMAR baseline BCVA improved 0.1 logMAR (1 line); two children with 0.8 logMAR baseline BCVA improved 0.2-0.4 logMAR (2-4 lines). Fellow eye BCVA did not change significantly during the study (p= 0.35). Discussion: Binocular movie treatment yields a significant improvement in the amblyopic-eye BCVA after 2 weeks (about 9 hours) of treatment in children. The presentation of popular animated feature films may result in better compliance in children than binocular iPad game play. Conclusion: Repeated binocular visual experience, with reduced fellow eye contrast, improves vision in the amblyopic eye. Monocular improvement in the absence of fellow eye occlusion suggests that amblyopia is, at least in part, due to chronic interocular suppression. References: 1.

To date, these studies failed to distinguish the effects of strabismus from the effects of amblyopia on performance and did not include tasks typical of children’s daily activities in school. Methods: Thirty-seven children (7-12y) with anisometropia, strabismus, or both (23 amblyopic & 14 non-amblyopic) and 14 age-matched normal control children were enrolled. Children had eye movement recording while silent reading a grade appropriate passage of text for comprehension binocularly (Readalyzer™), and were timed while transferring answers from a standardized reading achievement test to a Scantron® multiple choice response form. Visual acuity, stereoacuity, and interocular suppression were also tested. Child wore their habitual optical correction for all testing. Results: Reading rate for amblyopic children was significantly slower (119±33 words per min) than for normal children (192±39; p=0.01) and for non-amblyopic children with strabismus (219±50; p<0.0001). Both the number of fixations and the number of regressive saccades per 100 words were significantly higher for amblyopic children (p=0.007 and 0.03, respectively). Comprehension scores did not differ among groups. Reading rate was significantly correlated with amblyopic eye visual acuity (p=0.001) and depth of suppression (p<0.0001) but not stereoacuity. Time to complete the Scantron® (sec) was significantly greater for amblyopic children compared to normal controls (p=0.03). Scantron® completion time was significantly correlated with depth of suppression but not with amblyopic eye visual acuity or stereoacuity. Discussion: Amblyopia results in slower reading rate and Scantron® completion and is associated with abnormal eye movements during reading and interocular suppression. Conclusion: Slow reading can hamper amblyopic children in schoolwork and affect performance on timed, standardized tests. Schools may need to implement academic accommodations to allow students with amblyopia to succeed. Paper 32 Saturday 12:13 - 12:20 pm Detection of Strabismus by the Spot Vision Screener Mae Millicent W Peterseim Jennifer D Davidson Rupal H Trivedi Edward W Cheeseman M Edward Wilson Carrie E Papa Storm Eye Institute/ Medical University of South Carolina Charleston, South Carolina Introduction: AAPOS guidelines for Amblyopia Risk Factors (ARF) to be detected by automated vision screeners include manifest strabismus of 8 PD in primary position. The Spot vision screener is a new automated screener designed for use in schools and pediatric offices. The Spot refers children for strabismus based upon the device’s measurement of ‘gaze’. We sought to determine the efficacy of the Spot in detecting ARF strabismus when compared to pediatric ophthalmologist examination. Methods: In this prospective study, new and return patients seen in the pediatric ophthalmology clinic underwent screening with the Spot vision screener, version 1.1.51, prior to a complete examination by a pediatric ophthalmologist. A Redcap database was created including Spot referral status and results of the examination. Patients who were referred by the Spot for ‘gaze’ were included as test positives. Patients found to have constant strabismus of 8 PD or greater in primary position by the physician were considered to have ARF positive strabismus. Results: 444 patients, average age 72 months (11-221 mo) were included. 92/444 (21%) children met ARF for strabismus criteria by the pediatric ophthalmologist examination. The sensitivity of the Spot to detect ARF strabismus risk factors is 77.17% and the specificity 93.73%. PPV is 76.34% and NPV is 94.0% in our population. Discussion: The Spot demonstrates good sensitivity and excellent specificity for detecting AAPOS Amblyopia Risk Factor strabismus Conclusion: The new Spot vision screener is useful in detecting strabismus in children.

A smart phone platform has potential benefits of portability and implementation. This represents an interim analysis of a prospective study to introduce and assess a mobile smart phone (GoCheckKids) with automated image-processing analysis for a vision-screening device. Methods: 235 patients aged 12-72 months , were enrolled from 2 sites. Children were consented and then evaluated using smart phone photoscreening and cycloplegic (gold standard) refraction. Age ranged for 12-30, 31-48, and 49-72 months (n=58, 44, and 72 respectively). Only completed age ranges (49-72) reached the minimum for statistical population requirements (n=70). Automated image-processing algorithms were optimized for maximum sensitivity/specificity to AAPOS photoscreening guidelines1 for ARFs. Results: Optimized overall ARF sensitivity/specificity for the automated mobile photoscreener compared too cycloplegic refraction in the older children: 60%/82%. Expert manual image grading was comparable at 60%/89%. Younger children have more unreadable images. Discussion: The mobile smart phone photoscreening system is effective for the detection of ARFs. These initial instrument thresholds were set for maximum specificity while retaining reasonable sensitivity to reduce false positives. Conclusion: Gobiquity’s mobile smart phone photoscreener with automated image processing analysis is a viable vision-screening device in the detection of amblyopia risk factors in preschool children.

Validation of photo screening technology in the general pediatrics office Jana A Bregman Barron L Patterson MD Sandy Owings Sean P Donahue MD Vanderbilt University Medical Center, Nashville, TN Introduction: Automated preschool vision screening allows for the detection of amblyopia risk factors (ARFs) in preverbal children. While most photoscreening instruments have been validated in pediatric ophthalmology clinics and field studies, validation in the medical home is lacking. We performed the first large scale multi-office evaluation of two commercially available photoscreening devices in the medical home. Methods: Nine large pediatric practices were recruited to perform photoscreening of 4500 children aged between 18 months and five years at well child examinations. Thus far 1534 children (of anticipated 3750) were screened using SPOT while 308 (anticipated 750) were screened using Plusoptix S12. (NOTE TO Pgm Ctee: At current rates anticipate full enrollment in December). Referred children received comprehensive eye examination with cycloplegic refraction to determine predictive value using AAPOS VSC guidelines. A selected sample of 2% of passed children had eye exams to calculate sensitivity and specificity. Results: The referral rate for SPOT was 9% compared to 20% for PlusOptix. The most common reason for referral for each instrument was suspected astigmatism (45% for SPOT, 68% for PlusOptix). Amblyopia risk factors were confirmed in 70% of examined referred children using SPOT compared to 40% with PlusOptix. The higher PVP for SPOT was primarily due to a lower PVP for suspected astigmatism in patients screeed using PlusOptix. PVP for suspected anisometropia, and suspected hypermetropia were similarly high for both instruments; PVP for suspected strabismus remained low for both. Discussion: This study is the first to evaluate automated vision screening in the medical home and nearly identically replicates previously reported studies from day care settings and preschools. Conclusion: SPOT and PlusOptix are each effective for the detection of ARFs when used in the pediatric outpatient setting. References: Donahue SP et al.

They are also thought to serve as an optimal sampling strategy while viewing complex visual scenes. The goal of our study was to assess the influence of amblyopia on microsaccades. Methods: 23 amblyopes(mild =7;moderate= 10;severe=6) and 10 controls participated in the study. Eye movements were recorded using infrared video-oculography during amblyopic and fellow eye viewing while the subjects performed 3 tasks a)prolonged visual fixation b)viewed a gray background c)identified picture differences. Results: There was a decrease in the frequency of microsaccades with increasing severity of amblyopia (median:mild=1.8Hz;moderate=1.4Hz;severe=0.5Hz,AN OVA p<0.05). The micro-saccade amplitude decreased with increasing severity of amblyopia(median:mild=0.59°; moderate=0.57°; severe=0.49°,ANOVA p<0.05). The frequency of microsaccades while viewing a gray background were 50% less compared to when viewing a complex visual scene. The ability to identify picture differences was diminished (decrease correct responses with increased reaction time) in severe compared to mild amblyopia. Discussion: The brain increases the rate of microsaccades to aid visual exploration in demanding tasks. The relative increase in production of microsaccades while viewing crowded visual scene is diminished in severe amblyopes. These results suggest that central nervous system is unable to increase the microsaccade rate to aid viewing of a complex picture in amblyopia. Conclusions: Microsaccades could be a novel biomarker to assess severity/treatment response in amblyopia. Alteration in micro-saccades could explain the difficulty in perceiving details of a complex picture evident as crowding phenomenon in amblyopia. 44 Notes 45 Notes 46 Poster Schedule 1st Set of Hard Board Posters (1-28) displayed from Wednesday, March 25, 4:00 PM - Friday, March 27, 11:30 AM, Storyville Hall Interactive Poster Session - Author Presentation and Q/A - Thursday, March 26, 10:00 - 11:00 AM STRABISMUS Poster #1 Strabismus Outcomes in the Infant Aphakia Treatment Study Erick D.

Methods: Secondary outcome analysis was done in this randomized, multicenter, clinical trial comparing treatment of unilateral aphakia with a primary IOL or contact lens (CL) in 114 infants. The proportion of patients who were orthotropic at distance and near at 5 years of age as well as the proportion of patients who underwent strabismus surgery were compared between treatment groups using Fisher’s exact test. Results: At 5 years of age, 8 of 57 (14%) children in the CL group and 14 of 56 (25%) in the IOL group were orthotropic at distance (P=0.16) and had no history of strabismus surgery. For near fixation, 11 vs. 11 (19% vs. 20%) were orthotropic (P = 0.99). The number of patients requiring strabismus surgery prior to age 5 was 21 in CL group (37%) and 24 in IOL group (43%) (P = 0.57). Discussion: Previously presented IATS data documented a high rate (70.4%) of strabismus in the first year after cataract surgery. At the 5-year close of the study, children in both the IOL and CL treatment groups continued to develop strabismus. Conclusion: Intraocular lens placement does not eliminate the early development of strabismus or the need for extraocular muscle procedures after monocular congenital cataract surgery.

Divergence Insufficiency: Increased Incidence and Hypothesis Regarding Etiology Justin D Marsh David L Guyton Introduction: For reasons unknown, age-related divergence insufficiency (DI) is being diagnosed more frequently [1]. We sought to determine if the incidence of DI has increased, and, if so, to propose a mechanism to explain the increased incidence. Methods: Patient records were analyzed to determine the yearly incidence of diagnosed DI and operated cases, ages > 50. Patients were excluded with a known etiology for strabismus or history of prior strabismus surgery. Results: The number of new cases of DI in 1989-1992 was 3 compared with 63 in 20092012 (P < 0.001). Twenty-nine of these patients had undercorrected accommodative demand at near. When excluding patients with esotropia at near, the distance deviation correlated with the undercorrected accommodative demand at near (R2 = 0.46). Five patients underwent surgery for DI in 2003-2004, compared with 12 in 2013-2014 (P = 0.012). The median time from onset of symptoms to diagnosis during these periods was 5.5 and 5.0 years, respectively. Discussion: We found an increase in diagnoses and surgeries for DI over the periods analyzed. This increase in documented cases of DI does not appear to be due to increased awareness of disease or decreased lag time between onset of symptoms and diagnosis. Conclusion: Increased visual demands at near, such as the viewing of desktop monitors through progressive power lenses, may activate the near triad, increase convergence tonus, and shorten the medial rectus muscles via unwanted muscle length adaptation, perhaps contributing to the minor epidemic of DI that is unexplainable by connective tissue degeneration.

All patients reported at least 1 of the following: asthenopia with reading, diplopia at near. All subjects had a near exophoria at least 4 PD greater than at distance, and access to a computer with a CD/DVD player. Measures: Objective: Near point of convergence (NPC) and near convergence amplitude (NCA) at baseline, intermediate, and final examinations. Subjective: Presence or absence of diplopia and asthenopia with reading at baseline and final examinations. Results: 74 subjects (40%) reported diplopia and all subjects reported asthenopia. Baseline measurements were a mean NPC of 6 cm and NCA of 20 PD. 89% of subjects achieved good or excellent compliance during the initial 6 weeks of therapy. CVS therapy duration averaged 18 weeks. Therapy was discontinued an average of 64 weeks before the final assessment. 170 subjects (92%) were asymptomatic at final assessment. Final measures were a mean NPC of 3 cm, and mean NCA of 38 PD. 12 subjects required other treatment modalities. Discussion: (see conclusion) Conclusion: Home-based CVS therapy may reduce symptoms and improve the NPC and NCA of children age 5-18 years with symptomatic CI. Poster 4 Thursday 10:00 - 11:00 am Heavy Eye Syndrome (HES) and Sagging Eye Syndrome (SES) in High Myopia Roland Joseph D Tan MD, Joseph L Demer MD, PhD Stein Eye Institute 100 Stein Plaza, David Geffen School of Medicine at UCLA, Los Angeles, California Introduction: HES presents with limited abduction and supraduction due to superotemporal globe shift relative to extraocular muscles. SES was described in non-myopic patients, presenting with distance esotropia and cyclovertical strabismus due to lateral rectus (LR) inferodisplacement caused by LR-SR band degeneration. We supposed that SES might also cause strabismus in high myopia. Methods: Eleven strabismic patients with axial high myopia underwent ophthalmological examination and orbital MRI to assess the LR-SR band and displacement angles between LR and superior rectus (SR). Results: Five highly myopic patients with mean axial length of 32±5mm had HES. Distance esotropia averaged 68±42PD and hypertropia 26±21PD. The LR-SR band was thinned in 6 and ruptured in 2 orbits, with superotemporal globe prolapse. The mean angle between SR and LR centroids was 121±7°. Six highly myopic patients with mean axial length of 32±6mm exhibited SES. Distance esotropia averaged 23±57PD and hypertropia 2±2PD. The LR-SR band was thinned in 7 and ruptured in 5 orbits, with superotemporal soft tissue prolapse. The mean angle between SR and LR centroids was 104±11°, significantly less than in HES(P<0.001). Discussion: SES occurs in highly myopic patients who exhibit less relative displacement between SR and LR than in HES. Unlike HES, SES exhibit superotemporal soft tissue prolapse that may limit superotemporal globe shift. The distinction is important because surgery for HES requires SR to LR union, while surgery for SES is conventional. Conclusion: SES can cause strabismus in high axial myopia. Orbital MRI is useful in differentiating SES from HES. References: 1. Larsen PC, Gole GA. Partial Jensen’s procedure for the treatment of myopic strabismus fixus. J. AAPOS. 2004;8:393-395. 2.

We present a case series of novel finding of amyloidosis involving superior oblique (SO) muscle in Brown syndrome Methods: A total of three patients with Brown syndrome (5 eyes) were identified. Indications for surgery were abnormal head posture and significant strabismus in primary position. Surgical options included SO tenectomy for hypotropia and lateral rectus and medial rectus recession for exotropia and esotropia respectively. The excised tendon of superior oblique was sent for histopathological examination Results: Two of three cases were had congenital Brown syndrome. Two cases were bilateral. One patient had associated congenital ptosis. Orbital imaging performed in two cases was normal. All patients had chin elevation of more than 5 degrees. The mean preoperative deviation was 7 prism diopters (PD) of hypotropia, 22 PD of exotropia and 10 PD of esotropia. The mean postoperative deviation was zero PD hypotropia, 5 PD exotropia, 3 PD esotropia. Histopathology samples of all the 3 patients revealed amyloidosis of superior oblique. None had features of systemic amyloidosis. Discussion: Orbital amyloid deposits have been described with generalized primary and secondary amyloidosis commonly involving the lids, conjunctiva and lacrimal apparatus. Localized orbital amyloidosis involving extraocular muscle is rare. To the best of our knowledge this is the first report describing association of amyloidosis with superior oblique tendon presenting as Brown’s syndrome. Conclusion: Localized orbital amyloidosis of superior oblique may lead to secondary changes in the tendon causing restrictive strabismus. References: 1.Holmström GE, Nyman KG.

The cause of these disorders is thought to be secondary to poor ergonomic posture in both the clinic and the operating room. The incidence of MSD among dentists is considered to be even higher and the dental field has taken steps to identify high risk activities and attempt to modify the work environment in order to reduce this risk. Recently, an evaluation tool has been shown to be useful in identifying dental operator postures that can be harmful. This study looked at utilizing a similar tool to evaluate strabismus surgeons. Methods: Strabismus surgeons were monitored during surgery and their posture was evaluated using a tool established for examining dentists during operative procedures. The testing process was compared to similar evaluations made during dental procedures. Results: The evaluation process was found to be similar for the postural assessment of strabismus surgeons during surgery to that used to examine dentists. Discussion: Neck and back pain are common disorders among ophthalmologists. Identifying postural habits that are ergonomically unsound can help to reduce the risk of these problems. A previously designed dental tool can be modified to allow evaluation of postures seen during strabismus surgery. Conclusion: An evaluation tool which has been modified for dental use may be able to help identify unsafe operating postures seen during strabismus surgery and suggest operating positions and techniques that would be safer for the surgeon performing strabismus surgery. 51 Poster 6 Thursday 10:00 - 11:00 am Poster 7 Thursday 10:00 - 11:00 am Treatment of surgical sutures with antiseptic or antibiotic to reduce suture contamination: an in vitro experiment Namratha Turlapati Mark Ruttum Sue Kehl Medical College of Wisconsin, Milwaukee, WI Introduction: The purpose of this study is to determine if treatment of sutures used in strabismus surgery with antibiotic or antiseptic can significantly reduce suture contamination. Methods: Sutures (6-0 polyglactin) were divided into four groups: (1) untreated (control); (2) 10% povidone-iodine; (3) gentamicin 2.5% solution; and (4) gentamicin ophthalmic ointment. Treated sutures were soaked in the antibacterial agent for five minutes and then briefly exposed to each of four bacterial species (S. pneumoniae, S. aureus, S. epidermidis, and H. influenzae). The sutures were cultured and growth was measured in colony forming units at 24 hours. The Kruskal - Wallis exact test was used for statistical analysis. Results: The 10% povidone iodine suture group had no growth following bacterial exposure. This was significantly different from the control and antibiotic treated suture groups (p < 0.0001). In contrast, the untreated control, gentamicin 2.5% solution treated, and gentamicin ophthalmic ointment treated groups had growth after bacterial exposure and were not found to be significantly different. Discussion: Suture contamination during strabismus surgery has been reported and is the suspected mechanism of infectious post-operative endophthalmitis. The absence of bacterial growth from the 10% povidone-iodine treated suture group suggests pre-treating sutures with antiseptic may decrease suture contamination and theoretically could lower the incidence of infectious endophthalmitis following strabismus surgery. Conclusion: Treatment of sutures with 10% povidone-iodine is shown to significantly reduce suture contamination in an in vitro setting. Further studies to determine the safety and efficacy of this practice are required. References: 1. Eustis et al. Suture Contamination in Strabismus Surgery.

Poster 8 Thursday 10:00 - 11:00 am Slipping the knot: A comparison of knots used in adjustable suture strabismus surgery Kyle E Miller MD1,2 Michael Kinori MD1 Shira L Robbins MD1 Scott K McClatchey MD2 David B Granet MD1 1Anne and Abraham Ratner Children’s Eye Center at the University of California, San Diego La Jolla, CA 2Department of Ophthalmology, Naval Medical Ceneter San Diego Introduction: Adjustable suture strabismus surgery has been performed for many years and multiple suture tying techniques have been developed. These tying techniques are meant to hold the muscle in place well yet also slide to allow adjustment. The friction related to this process has not been well characterized. Methods: To allow the simulation of strabismus surgery tying methods a model using 6-0 polyglactin 910 suture (Vicryl, Ethicon) was created. After each knot was tied a digital force meter was used to measure the force (gram-force, gf) required to overcome the static friction created by the knot. Each simulation was repeated with new suture material five times and the force required after subsequent repositioning was also recorded. Results: The force to overcome static friction for the sliding noose knot was 226gf [90%CI, 181-271], cinch knot: 135gf [90%CI, 99-171], and square knot: 82 gf [90% CI, 68-96]. Subsequent movement of each knot along the same suture required progressively less force with the sliding noose maintaining the most static friction. Discussion: All knots in this study generate frictional forces greater than can be overcome by the average horizontal extraocular muscle1; however, only the sliding noose would confidently hold the maximal force generated.1 Consideration should be taken when moving the knot multiple times due to the decreased force required with each movement. Conclusion: In a strabismus surgery model the sliding noose knot had the greatest frictional force generated and maintained the most static friction after subsequent repositioning. References: 1.

In this study, we measured comitance (difference between right and left gaze strabismus measurements) to assess change in comitance (CIC) after strabismus surgery. Methods: Medical records of horizontal strabismus surgical procedures at a single institution over a 2-year period were retrospectively reviewed. Inclusion criteria included side gaze measurements recorded before and after surgery. The main outcome measure was CIC after surgery. Results: The review identified 569 procedures meeting inclusion criteria. Of the 491 with comitant preoperative alignment, 59 developed postoperative incomitance, of whom 91% had asymmetric surgery. Of the 78 with incomitant preoperative alignment, 35 (45%) improved to comitance postoperatively; 100% of these patients had asymmetric surgery. Asymmetric 2-muscle surgery (recess/resect procedure) was associated with the largest CIC while symmetric 2-muscle surgery had the smallest (P<0.0001). CIC of =25PD was observed in 7 patients with asymmetric surgery (0 with symmetric surgery). Simultaneous vertical muscle surgery did not significantly alter CIC. Discussion: Asymmetric surgery had the largest effect on CIC. Symmetric surgery did not significantly alter CIC. Some patients with asymmetric surgery had very large CIC. Vertical surgery did not affect CIC overall. Conclusion: Asymmetric surgery can treat patients with incomitance but can also create incomitance in patients who were previously comitant. Surgical planning should include consideration of potential for CIC, especially in patients who are sensitive to diplopia or to the social implications of incomitant strabismus. Long-term success in surgically and non-surgically managed intermittent exotropia Sarah R Hatt DBO David A Leske MS Jonathan M Holmes BM, BCh Mayo Clinic Rochester, Minnesota Introduction: Previous authors have reported high recurrence rates following surgery for childhood intermittent exotropia (IXT). In addition it is possible that some cases may resolve without surgery. We compared long-term success in surgically and non-surgically managed patients. Methods: Children with IXT and 5 years follow-up (minimum 3 years) from their first surgery were retrospectively identified. A cohort of comparable non-surgical patients was identified by matching each surgical patient for age at onset and age at the 5-year examination. At the exam closest to 5 years follow-up, success was defined as no manifest tropia on examination or by history, no new monofixation (stereoacuity subnormal for age) and no additional surgery. Success rates were compared between surgical and non-surgical groups. Results: 33 children with IXT had surgical correction and 5 years postoperative followup, and were matched with 33 non-surgical patients (total follow-up 7.2 ± 2.6 years vs 6.8 ± 2.3 years). There were no significant differences between groups for baseline angle of deviation (P>0.4). The success rate at 5 years was 30% in the surgical group and 12% in the non-surgical group (P=0.1; difference 18%, 95% CI -1% to 37%). Discussion: After an average of 7 years follow-up, the majority of both surgical and nonsurgical patients continue to demonstrate a constant or intermittent manifest deviation. Only a small proportion of patients in both groups met our definition for success. Conclusion: In childhood intermittent exotropia, long-term success is difficult to achieve with surgical intervention, and some patients managed non-surgically will spontaneously resolve. 53 Poster 10 Thursday 10:00 - 11:00 am Poster 11 Thursday 10:00 - 11:00 am Characteristics, Surgical Management and Outcomes of Adult-Onset Cranial Nerve Six Palsy Sara F Grace MD Kara M Cavuoto MD Hilda Capo MD Bascom Palmer Eye Institute Miami, Florida Introduction: Cranial nerve six palsy (CNVI P) is a common etiology of adult-onset strabismus. Our series describes the characteristics, surgical management and outcomes of adult-onset CNVI P. Methods: Retrospective chart review of 87 patients that underwent strabismus surgery for adult-onset CNVI P in the past 15 years at a large academic center. Results: In order of incidence, the three most common etiologies were trauma (30.3%), intracranial masses (24.7%) and ischemia (15.7%). The mean age at diagnosis and surgery was 50 and 54 years, respectively. Diplopia was present in 96%, with 37% using prism correction prior to surgery. The mean deviations were 41 ± 23 prism diopters at distance and 34 ± 23 prism diopters at near. Transposition procedures were utilized in 30%, adjustable sutures in 65% and botulinum toxin injection in 9%. The success rate (< 10 PD) was 84% in non-transposition procedures as compared to 60% in transposition procedures (p=0.027). Resolution of diplopia was achieved in 61% of patients, with 24% of patients undergoing additional surgery and 15% requiring prism correction. Discussion: In our study, the majority of patients diagnosed with CNVI P were relatively young and had trauma or brain tumors. These etiologies frequently resulted in esodeviations that were larger and less likely to improve than the ischemic palsies seen in the elderly, which may have led to surgical correction. Conclusion: Multiple surgical options yield good results in CNVI P. The results of transposition procedures are not as successful as non-transposition surgeries; however, this may be attributed to their utilization in cases of more severe compromise of lateral rectus function. Poster 12 Thursday 10:00 - 11:00 am Retinal Dysfunction and Nerve Fiber Layer Loss in Pediatric Patients on Vigabatrin: An ERG and SD-OCT Study Joshua M Barnett Natalie Kerr Alessandro Iannaccone Hamilton Eye Institute, University of Tennessee Health Science Center Memphis, TN Introduction: To report on patients treated with therapeutic levels of vigabatrin (VGB) for epilepsy followed prospectively for possible VGB-related changes in retinal nerve fiber layer (RNFL) thickness, macular microanatomy, and retinal function. Methods: Nine patients with VGB-treated epilepsy (age: 0.5-17 yo; mean 5.49±6.2 yo) followed every 6 mos. (average: 1.4 yrs) were included in this observational case series. Exams included spectral domain optical coherence tomography (SD-OCT) and full-field flash electroretinogram (ERG), conducted under anesthesia in a hospital setting. Results: Three of the nine patients exhibited signs of VGB-related toxicity following treatment durations of 7.8, 11.2, and 33.6 mos. A RNFL thickness reduction of 22±5 µm was seen in the superior quadrant. No macular SD-OCT changes were seen. Two of these three patients exhibited also ERG changes, one had selective photopic and mixed b-wave amplitude loss (electronegative ERG) attributable to ON-response compromise, and another selective mixed a-wave amplitude loss, attributable to photoreceptor compromise. Discussion: Both RNFL loss and ERG changes were documented in 3 of 9 cases followed prospectively. RNFL loss was observed over time in all cases only in the superior quadrant. ERG changes varied, and included signs of photoreceptor toxicity (a-wave loss) and compromise of the photoreceptor-to-ON bipolar cell synapse (or of the ON bipolars themselves). Conclusion: These findings confirm that VGB-treated pediatric patients are at risk of suffering multiple changes in their visual system in conjunction to VGB use, and add further information to the complex spectrum of the known VGB-mediated visual function toxicity effects. 54 Visual Outcomes in Congenital Foveal Toxoplasmosis Smith Ann M Chisholm MD Gregg T Lueder MD Washington University in St. Louis St. Louis, MO Poster 13 Thursday 10:00 - 11:00 am Introduction: Congenital macular lesions attributed to toxoplasmosis may limit potential visual acuity. The appearance and location of these scars may cause physicians to overlook associated amblyopia. This study reviews the visual outcomes and benefits of amblyopia therapy in children with foveal toxoplasmosis scars. Methods: Retrospective review of ten children with presumed foveal toxoplasmosis scars. Photographs were obtained in all patients and optical coherence tomography (OCT) was performed in five patients. Results: Average age at presentation was 3.8 years old and average follow-up was 6.3 years. Occlusion therapy was undertaken in nine patients. Average duration of occlusion therapy was 1.7 years. Six patients improved with occlusion therapy (average 4.6 lines gained on optotype acuity). Final visual acuity ranged from 20/20 - 20/250, with 8 patients better than 20/80. OCT confirmed macular scars in all patients, with varying degrees of foveal architecture disruption. Discussion: Despite the striking appearance of the lesions in some patients with foveal toxoplasmosis, visual potential may be better than expected. The appearance of the lesions is not predictive of visual outcome. Improvement in visual acuity following occlusion therapy may occur in many patients. Conclusion: Visual outcomes in children with foveal toxoplasmosis may be better than predicted based on the appearance of the lesions. A trial of occlusion therapy to treat amblyopia should be initiated in these patients to ensure that they reach their maximal visual potential. References: 1. Kushner BJ.

Fluorescein Angiography versus Fundus Photography on the Diagnosis and Management of Retinopathy of Prematurity Samir N Patel Michael A Klufas MD Michael C Ryan Karyn E Jonas RN Susan Ostmo MPH Audina M Berrocal MD Michael F Chiang MD R.V. Paul Chan MD Weill Cornell Medical College, New York Introduction: Fluorescein angiography (FA) is an imaging modality that may provide useful information regarding the retinal vasculature in the premature retina; however, little information exists on the utility of FA in patients with retinopathy of prematurity (ROP). The purpose of this study is to (1) examine and compare how fundus photography and FA influence the identification of the fovea in ROP and (2) evaluate the influence of FA on the diagnosis and management of ROP. Methods: 32 sets (16 fundus photographs; 16 fundus photographs paired with corresponding FAs) of wide-angle retinal images obtained from 16 eyes of eight infants with ROP were compiled on a secure web site. 9 ophthalmologists (3 pediatric ophthalmologists; 6 vitreoretinal surgeons), with experience in ROP diagnosis and management, interpreted each image set, identified the fovea, and provided a diagnosis of zone, stage, plus, and category. Sensitivity and specificity was calculated using a consensus diagnosis, determined from diagnosis of the color fundus images by three independent readers in combination with the ophthalmoscopic examination. Results: A computer-generated diagnosis of zone based on a subject’s identification of fovea agreed with that subject’s diagnosis of zone in 3.1 of 5 (62%) cases using fundus photographs and in 3.4 of 5 (68%) cases using FA. When interpreting fundus photography alone versus fundus photography and FA, mean sensitivity improves for detection of stage 3 or worse disease (39.8 to 74.1), zone I (47.2 to 61.1), type 2 or worse disease (69.4 to 86.8) and treatment requiring disease (22.2 to 40.3). Using the kappa statistic, inter-grader agreement for identification of treatmentrequiring ROP improved significantly when viewing the fundus photographs + FA as compared to viewing the fundus photographs alone. Discussion: There is variability between identification of the macular center and concordance with the subjective diagnosis of zone. FA supplementation can improve sensitivity for certain subtypes of ROP zone, stage and category as well as increasing intergrader agreement for treatment-requiring ROP. Conclusion: FA continues to have an evolving role in the diagnosis and management of ROP. FA may be most helpful in determining Zone I ROP. 55 Poster 14 Thursday 10:00 - 11:00 am Poster 15 Thursday 10:00 - 11:00 am Patterns of Retinal Hemorrhage Associated with Pediatric Cerebral Sinovenous Thrombosis Julia E Reid MD David L Rogers MD Anne Jensen MD Brian J Forbes MD PhD Lori L Billinghurst MD MSc Gil Binenbaum MD MSCE Nationwide Children’s Hospital and The Children’s Hospital of Philadelphia Columbus, OH and Philadelphia, PA Introduction: To report the prevalence and characteristics of retinal hemorrhage (RH) in children with cerebral sinovenous thrombosis (CSVT), which has been proposed as an alternative explanation for RH in children evaluated for abusive head trauma. Methods: Multicenter retrospective cross sectional study of children older than 6 weeks with newly diagnosed CSVT and dilated funduscopic examination. Primary outcomes were the presence of RH and pattern of RH. Results: Twenty-nine children (median age 9 years, range 7 weeks to 17 years) were studied. Eighteen retinal exams occurred within 72 hours of CSVT diagnosis; 11 were within 4 to 10 days. Five (17%) children had RH. In 4 of 5 children, the RH was peripapillary, superficial intraretinal, and adjacent to a swollen optic disc. In the fifth child, who had meningitis, sepsis, and multiple cerebral infarcts, there were numerous white-centered intra-retinal hemorrhages and one preretinal hemorrhage. Eighteen (62%) children had disc swelling. CSF opening pressure was recorded in 13 children (mean 37 cm-H20, range 27-59). CSVT risk factors included meningitis(6), mastoiditis(5), and hypercoagulability(5). Discussion: RH in children with CSVT was uncommon. Hemorrhages were few in number, peripapillary, and associated with optic disc swelling. One child with deeper intraretinal and one preretinal hemorrhage had florid sepsis, a recognized independent cause of RH. Conclusion: RH associated with pediatric CSVT is characteristically superficial and adjacent to a swollen optic disc. When RH extends into the rest of the posterior pole or periphery, is multilayered, or occurs in the absence of disc swelling, another etiology for the RH should be sought. Poster 16 Thursday 10:00 - 11:00 am Predictors for the Development of Referral-Warranted Retinopathy of Prematurity in the Telemedicine Approaches to Evaluating of Acute-Phase ROP (e-ROP) Study Gui-shuang Ying Graham E Quinn Kelly C Wade Michael X Repka Agnieshka Baumritter Ebenezer Daniel Scheie Eye Institute, University of Pennsylvania Philadelphia, PA Introduction: Detection of treatment-requiring retinopathy of prematurity (ROP) involves serial eye examinations. A ROP prediction model using predictive factors could identify high-risk infants and reduce required eye examinations. This study is to determine predictive factors for referral-warranted ROP (RW-ROP). Methods: Secondary analysis of data from the e-ROP Study. 1257 Infants with birth weight (BW) <1251g had serial ROP examinations to detect RW-ROP (defined as presence of plus disease, Zone I ROP, or ROP stage 3 or greater in either eye). Results: In a multivariate model, significant predictors [odds ratio (95% confidence interval)] for RW-ROP were: male [1.80 (1.13–2.86)], nonblack race [2.76 (1.50–5.08) for White vs. Black and 4.81 (2.19-10.6) for other vs. Black], low BW [5.16 (1.12–7.20) for </=500g vs. >1100g], low gestational age [9.79 (3.49–27.5) for </=24 weeks vs. >/=28 weeks], number of quadrants with preplus disease [18.4 (4.28–79.4) for 3-4 quadrants vs. no preplus], stage 2 ROP [4.13 (2.13–8.00)], retinal hemorrhage [4.36 (1.57–12.1)], need for respiratory support [11.0 (2.26 – 53.8)], and slow weight gain [2.44 (1.22 – 4.89) for weight gain </=12g/day vs. >18g/day]. Discussion: Using a ROP prediction model could identify lower risk infants who require less frequent imaging or eye examinations and also identify highest risk infants who require more intensive imaging and examination schedules. Conclusion: When controlling for very low BW and prematurity, presence of preplus disease, stage 2 ROP, retinal hemorrhage, and need for ventilation at time of first studyrelated eye exam were strong independent predictors for RW-ROP. 56 Training retinal imagers for Retinopathy of Prematurity (ROP) screening Karen A Karp BSN Agnieshka Baumritter MS Denise J Pearson COMT Maxwell Pistilli MEd, MS Gui-Shaung Ying PhD Graham E Quinn MD The Children’s Hospital of Philadelphia 34th and Civic Center Blvd. Philadelphia, PA 19104 Poster 17 Thursday 10:00 - 11:00 am Introduction: Retinopathy of prematurity (ROP) accounts for 13 % of the blindness in children in the United States. As of 2012 the AAP’s recommendations for ROP screening included remote retinal imaging as an acceptable screening method. The NEI-sponsored Telemedicine System for the Evaluation of Acute-Phase Retinopathy of Prematurity (e-ROP) Study reported the validity of retinal imaging with remote grading to screen for referral warranted ROP (sensitivity 90%, specificity 87%). Methods: e-ROP certified retinal imagers (CRI) were trained using a wide-angle digital camera to obtain a pupil image and 5 retinal images for each eye, while maintaining a safe patient environment. Data were collected to evaluate factors that might influence image quality. Results: Of 4205 imaging sessions, 4003 complete, 550 incomplete image sets were submitted. Submitted images were analyzed for image quality and 92% were gradable. Image quality was significantly affected by pupil size (<5mm: 55%, 5-6mm: 88%, and >6mm: 93%), image frequency (low volume 87% and high volume 95%), and ventilation mode (HFOV 68%, others 89-92%, no support 94%). Discussion: For remote retinal imaging to have a high sensitivity and specificity, it is importance that the CRI be well trained in image acquisition, ROP, and the population. Well dilated pupils, frequent imaging, and a well-positioned infant are all essential for successful image acquisition. Conclusion: The training of the e-ROP imagers was successful at maintaining quality images throughout the study period. Careful training and monitoring of CRIs are key components to using a telemedicine approach to ROP. References: 1.Ells AL, Holmes JM, Astle WF, et al.

A Closer Look at Retinopathy of Prematurity Persisting After 40 weeks and the Costs of Applying 2013 Screening Guidelines Natalie C Weil MD George B Hubbard MD Amy K Hutchinson MD Emory University School of Medicine, Atlanta, GA Introduction: In this study we describe the course of ROP that persists beyond 40 weeks and to calculate the rate of occurrence of pre-threshold ROP after 45 weeks. Also, to consider the monetary and intangible costs of extending ROP screening of infants with non-prethreshold ROP from 45 to 50 weeks. Methods: We performed a retrospective review of the medical records of outborn premature infants screened for retinopathy of prematurity at two tertiary facilities from May of 2013 to August of 2014. Results: We identified 135 infants with ROP that persisted after 40 weeks gestational age. Of those, 49 patients were excluded, (death, lost to follow up before screening was complete, initial exam after 45 weeks, only one exam, other medical conditions affecting ability to conduct exam) leaving 86 patients. Of these, 28 patients reached prethreshold disease and 9 required treatment. The earliest documented onset of prethreshold was 33 weeks and the latest was 44.5 weeks. Twenty patients did not reach prethreshold, but were followed for >45 weeks with a median of 2 additional visits at an additional monetary cost of 275.00 dollars per infant. Discussion: In 2013, the 2006 screening guidelines for ROP were modified to extend the recommended screening term for infants with non-prethreshold ROP from 45 to 50 weeks. 1,2. Conclusion: Based on this small study we conclude that additional research should be conducted on a large scale prior to holding physicians accountable to guidelines which have patient safety, financial and medical legal implications.

Methods: Thirty-four infants with type 1 ROP were treated with intravitreal injection of bevacizumab (IVB) at the dosage of 0.625 mg (22 patients) and 0.25mg (12 infants). Blood samples were collected prior to treatment and on post-treatment days 2, 14, 42 and 60. Weekly body weights were documented from birth until 60 days post treatment. Serum levels of bevacizumab and VEGF were measured with enzyme-linked immunosorbent assay (ELISA). Structural examinations and cycloplegic refractions were performed at age 1 year. Results: Serum bevacizumab level in IVB 0.25 mg group was lower than that in IVB 0.625 mg group, p=0.001. Half-life is 21 days. Serum bevacizumab levels were correlated with ROP status at the time of treatment. Serum VEGF levels decreased significantly in both groups 2 days post-treatment (P=0.0001) and remained at low levels. There were no significant differences in body weight gain between the two groups. Three eyes (8.3%) in IVB 0.625 mg group and two eyes (8.7%) in IVB 0.25mg group underwent laser treatment for recurrence of type I ROP. Two eyes (8.7) in IVB 0.25mg group had laser treatment for treatment failure. At 1 year of age, no retinal detachment was found in either group. The refractive errors were -0.28±3.4 and -1.0±1.6 in IVB 0.625mg and 0.25 mg group, respectively (p=0.26). Discussion: This is a pilot study. Conclusion: IVB at lower dosage (0.25mg) has similar efficacy as 0.625mg dosage but with significantly lower systemic exposure. Poster 20 Thursday 10:00 - 11:00 am Uncertainty in the diagnosis of Pre-plus Disease in Retinopathy of Prematurity Allison R Loh MD, Michael Ryan MPH, Katherine Abrahams, Esra Cansizoglu BS, R.V. Paul Chan MD, Audina Berrocal MD, Jayashree Kalpathy PhD, Veronica Bolon PhD, Deniz Erdogmus PhD, Michael F Chiang MD Oregon Health and Science University, Portland, OR Introduction: “Pre-plus disease” is abnormal arterial tortuosity and venous dilation less than the standard photograph1. One concern from clinicians is the definition of “pre-plus disease” requires qualitative interpretation. This study measures the impact of “pre-plus” categorization by examining diagnostic accuracy of experts, and by calculating quantitative tortuosity values. Methods: Wide-angle retinal images captured from 73 infants during ROP-screening were interpreted by 2 experts using a 3-level (plus/pre-plus/neither) scale. Image-based interpretations were integrated with the ophthalmoscopic exam to define a reference standard diagnosis. Images were analyzed quantitatively using a computer-based algorithm to generate a vascular tortuosity index (TI). Diagnostic performance of each expert and the computer-generated TI were compared based on absolute agreement and receiver operating characteristic area under the curve (AUC), with 3-level vs. 2-level (plus/not plus) classification. Results: Absolute agreement between experts and the reference standard was 92% in the 3-level classification, and 96% in the 2-level classification. Diagnostic performance of experts measured by AUC was 0.94 and 0.97 in the 3 and 2-level classification, respectively. Diagnostic performance of the computer-based TI measured by AUC was 0.91 in the 3-level classification, and 0.90 in the 2-level classification. Sensitivity and specificity of computergenerated plus-disease diagnosis were 89%-Sn/81%-Sp and 100%-Sn/66%-Sp in the 3 and 2-level classification respectively. Discussion: Diagnostic performance by experts was lower when the ROP classification system included pre-plus disease. Conclusion: Since diagnostic performance by experts was lower when the classification system included pre-plus disease, additional clarification of “pre-plus disease” may improve accuracy and consistency of diagnosis. In quantifying the spectrum between normal and plus disease, image based analysis may aid characterization of pre-plus disease.

No subject had any known ocular disorder. Their optic nerves were assessed using Optovue Optical Coherence Tomography (OCT). Data were compared to the normative database obtained by Optovue for adults, ages 18-25, 40-45, and 55-60. Comparisons included retinal nerve fiber layer (RNFL) thickness, thickness of ganglion cell complex (GCC), disc area (DA), vertical (VCD) and horizontal (HCD) cup-to-disc ratios, and cup area (CA). Results: In comparison to all adult age groups, the children’s optic nerves were statistically less cupped (CA, VCD, HCD), with all p-values less than 0.0001. No statistical difference was identified between the children and adults aged 18-25 and 40-45 with respect to RNFL or GCC. Both RNFL and GCC were thicker in the children when compared to adults aged 55-60 (p < 0.003). Children’s DA’s were marginally smaller than the adult population. Discussion: Our results demonstrate that young children’s optic nerves are statistically less cupped than those of all normal adult populations. The children’s RNFL and GCC are statistically thicker than those of adults aged 55-60. Conclusion: This study presents the first quantitative assessment of the optic nerve head, nerve fiber layer, and ganglion cell complex in normal four- to five-year old children. Results may help define optic nerve abnormalities in clinical practice. References: 1. Bendschneider D, Tornow RP, Horn FK, Laemmer R, Roessler CW, Juenemann AG, et al.

Methods: Circumpapillary RNFL thickness measures were acquired with the Spectralis (Heidelberg Engineering) SD-OCT using the eye-tracking feature at two separate study visits. Children with normal and abnormal vision (visual acuity >/= 0.2 logMAR above normal and or visual field loss) who demonstrated clinical and radiographic stability were enrolled. Intraand intervisit reproducibility was calculated for the global average and 9 anatomic sectors by calculating the coefficient of variation (CV) and intraclass correlation coefficient (ICC). Results: Forty-two subjects (median age 8.6 years, range 3.9 -18.2 years) met inclusion criteria and contributed 62 study eyes. Both the abnormal and normal vision cohort demonstrated the lowest intravisit CV for the global RNFL thickness. The papillomacular bundle demonstrated the lowest ICC and highest CV in the intravisit analysis for both cohorts. Intervisit reproducibility remained good for those with normal and abnormal vision, although small but statistically significant CV increases were observed for multiple anatomic sectors in both cohorts. The magnitude of visual acuity loss was significantly associated with the global (ß = 0.026, P < .01) and temporal sector CV (ß = 0.099, P < .01). Discussion: SD-OCT with eye tracking demonstrates highly reproducible RNFL thickness measures, although subjects with vision loss demonstrate greater intra- and intervisit variability than those with normal vision. Conclusion: Longitudinal changes in RNFL thickness can be reliably monitored in children using SD-OCT with eye tracking. 59 Poster 22 Thursday 10:00 - 11:00 am Poster 23 Thursday 10:00 - 11:00 am Pediatric Spectral Domain-Optical Coherence Tomography (SD-OCT) Normative Data for Novel Optic Nerve Parameters using the Heidelberg Spectralis Gena Heidary MD, PhD, Frank Weng, BS, Linda R. Dagi, MD Boston Children’s Hospital, Boston, MA Introduction: SD-OCT normative data for optic nerve volume (ONV) and the peripapillary papillomacular bundle thickness have not been reported, yet these parameters are relevant for neuro-ophthalmic disease. The purpose of this study was to determine pediatric norms for these parameters and expand the dataset for typical OCT parameters. Methods: Single center, cross-sectional, prospective study of subjects aged 4-18 years. Using the Heidelberg Spectralis NSite software, ONV and peripapillary retinal nerve fiber layer (rNFL) thickness measurements were obtained. Inclusion criteria were normal acuity and dilated exam, birth ≥ 37 weeks, and refractive error between -4 and + 4 diopters. Results: One hundred and fifty patients (58 % female) including 31% African American, 41% Hispanic, and 21% Caucasian or Asian patients participated. Five equal-sized age bins were represented. Mean total ONV was 2.48 mm3 (SD ±0.32 mm3). Average peripapillary rNFL thickness measurements were global thickness 104.65 microns (SD ±8.53 microns), peripapillary papillomacular bundle 57.03 microns (SD ± 8.61 microns), nasal superior 120.91 microns (SD ±20.89 microns), nasal 75.31 microns (SD ±14.32 microns), nasal inferior 120.66 microns (SD ±22.96 microns), temporal inferior 150.13 microns (SD ±17.46 microns), temporal 73.93 microns (SD ±10.74 microns), and temporal superior 148.43 (SD ±30.54). Discussion: This normative database using the Heidelberg Spectralis is from the largest reported cohort of pediatric patients with substantive distribution across age and diverse ethnicities. We introduce pediatric norms for ONV and peripapillary papillomacular bundle thickness. Conclusion: Normative data for SD-OCT ONV and rNFL thickness measurements are now available to enhance our ability to manage pediatric neuro-ophthalmic disease.

Poster 24 Thursday 10:00 - 11:00 am Visual Outcomes in Children with Dorsal Midbrain Syndrome as a Result of Pineal Tumors Julie K Calderwood MD Mary E Hoehn MD Greg Armstrong MD St. Jude Children’s Research Hospital, Memphis, Tennessee Introduction: Dorsal Midbrain Syndrome (DMS) is a well-known complication of pineal tumors characterized by a variety of ocular findings. The percentage of patients that develop these findings and whether treatments are needed has not been well described. Methods: We reviewed 84 charts of patients treated for pineal tumors at our institution since 1995. Twenty-three patients expired before they could be evaluated by ophthalmology. Thirty-five had an eye examination within 6 months of tumor diagnosis and were included in the study. The remaining patients were either never referred to the eye clinic or were referred more than 6 months after tumor diagnosis. Results: We found the incidence of DMS in our population to be 57.1% (n=20). Seventeen patients had vertical gaze paresis, 15 had pupillary light-near dissociation, 9 had convergence-retraction nystagmus, and 1 had eyelid retraction. Five patients developed convergence insufficiency, and 8 were noted to have intermittent exotropia. Improvement of DMS findings following treatment was seen in 4 patients, and only 2 experienced complete resolution. Strabismus surgery was recommended for 3 patients, and one was treated with convergence exercises. Discussion: Previous publications regarding DMS state that the findings resolve with tumor treatment. However in our population, 90% of patients that developed DMS had persistent ocular pathology even after treatment. Conclusion: Patients diagnosed with pineal tumors have a high incidence of DMS. A small number of patients with DMS will improve with tumor treatment, however most cases will have residual findings and some will require surgery or exercises to help improve symptoms.

The typically higher IOL powers needed may not be commonly stocked in every center. If a general anesthesia (GA) based AL is needed this might necessitate an additional operating room session. The purpose of this study is to examine whether AL measurement in awake infant/toddlers is feasible, and whether there is a difference in AL measurement between an office setting and under GA. Methods: A prospective comparative case study. Using the same instruments, AL measurements were obtained using a standard applanation technique twice; once in an office setting when the infant/toddler was awake, and once under GA in the operating room. To test for differences between measurements, a paired t-test was used Results: 33 eyes of 19 participants under the age of 28 months were examined. Average AL measurements were shorter by 0.12mm in the office setting than under GA (p=0.14). A mixed model analysis was used to generate a formula that can be used to predict AL under GA using the measurements obtained in an office setting Discussion: The findings here show that AL measurements in an office setting is feasible in most cases. No statistically significant difference was noted between measurements under GA compared to measurement in an office setting. Conclusion: AL measurement in of an infant/toddler in an office setting is generally reasonable to obtain. Management of iris cysts in children Carol L Shields MD Sara E Lally MD Jerry A Shields MD Wills Eye Hospital, 840 Walnut Street, Philadelphia, PA 19107 Introduction: There are 2 main categories of iris cysts in children including iris pigment epithelial (IPE) custs and iris stromal cysts. Most pigment epithelial cysts are small and stable, rarely requiring treatment. Iris stromal cysts tend to enlarge and produce photophobia and secondary glaucoma, requiring treatment. Methods: Review of 159 iris cysts for the outcome of type and intervention. Results: Of 768 patients with iris cysts, 159 were children (<20 years). The types included IPE cyst [pupillary margin (n=18, 11%), midzonal (n=29, 18%), peripheral (n=78, 49%), and dislodged (n=2, 1%)], iris stromal cyst (n=31, 20%) and epithelial downgrowth cyst (n=1, 1%). The IPE cysts rarely required therapy. The iris stromal cysts commonly required therapy including aspiration, additional cryotherapy, or additional alcohol sclerosis. Discussion: In our series, 20 eyes with iris stromal cyst required aspiration and alcohol sclerosis. The cyst measured median basal diameter of 12 mm and often occupied 50% or more of the anterior chamber. In each case, fine needle aspiration had been tried and failed, requiring further aspiration and alcohol sclerosis. Each eye received therapy under anesthesia using the operating microscope with a T-tube set up for aspiration and injection. Two or three washes of alcohol for maximum 2 minutes was performed at each treatment. The treatment was successful with one administration in 15 cases, but 5 patients required more than one treatment. Of the treated 20 eyes, 19 (95%) eyes were successful with cyst collapsed at median 5 year follow up. Only 1 patient failed, with severe photophobia, requiring surgical resection. Visual acuity remained stable or improved in 19 cases and worsened in 1 eye that developed cataract. Complications included transient corneal edema (n=4) and transient anterior chamber inflammation (n=1), which resolved with topical corticosteroids. There was no evidence of treatment-related glaucoma, epithelial downgrowth, tissue necrosis, retinal toxicity, or need for enucleation. Conclusion: Iris stromal cysts often require intervention. If aspiration alone fails, aspiration with alcohol sclerosis can be successful, allowing collapse of cyst without the need for open resection. References: 1.

Introduction: Peters anomaly is the most common cause of congenital corneal opacity. The variable severity of the disease mandates a tailored management approach. Here we present the clinical and visual outcomes of patients with Peters anomaly using such an approach. Methods: The charts of all Peters anomaly patients at the Hospital for Sick Children were reviewed retrospectively. Visual outcomes reviewed included visual acuity and the presence of nystagmus. Clinical outcomes included penetrating keratoplasty (PKP) survival and incidence of glaucoma and strabismus. Data were stratified per treatment modality chosen. Results: Sixty-four eyes in 44 patients were included in the study. Mean final best corrected visual acuity of the medical, surgical and no-treatment groups were 0.4 ± 0.1, 1.1 ± 0.8 and 1.3 ± 1.3 logMAR, respectively. Twenty-seven eyes (42.2%) developed nystagmus. Survival analysis of first PKP showed 83.7% probability for a clear graft at 24 months. Among the PKP eyes, thirty-one eyes (79.5%) retained a clear graft at last follow-up. Overall, Twenty-one eyes (32.8%) developed glaucoma. The incidence of strabismus was 56.3%. Discussion: Previous studies1,2 reporting Peters anomaly outcomes were either focusing on a single treatment modality or on a subgroup of Peters anomaly eyes. Our study shed light on the visual and clinical outcomes of Peters anomaly eyes after a mean long follow-up time over 4 years. Conclusion: Visual rehabilitation in Peters anomaly remains a great challenge. Mild cases necessitating monitoring or minor surgical intervention can achieve good visual outcomes. However in cases where PKP is indicated visual acuity is poor despite encouraging graft longevity. References: 1. Yang LL, Lambert SR, Lynn MJ, Stulting RD.

Poster 28 Thursday 10:00 - 11:00 am Epidemiology and Clinical Characteristics of Pediatric Eyelid Retraction Jessica A Olayanju MD Gregory J Griepentrog MD Brian G Mohney MD Mayo Clinic, Rochester, MN Introduction: Although eyelid retraction is a relatively rare form of eyelid malposition in children, there is no population-based data on this condition. The purpose of this study was to describe the incidence and clinical characteristics of eyelid retraction in children. Methods: The medical records of all pediatric patients (<19 years) diagnosed with eyelid retraction from January 1, 1976, through December 31, 2010, at Olmsted County, Minnesota were retrospectively reviewed. Results: A total of 62 were diagnosed during the study period, of which 15 were from a well-defined geographic region, yielding an annual incidence of approximately 1 in 77,519 patients younger than 19 years. The median age at diagnosis was 11.5 years (range 1 day to 18.72 years). Upper lid retraction occurred in 35 (56%) patients, lower in 18 (29%) patients, and both upper and lower retraction in 9 (15%) patients. The most common causes of lid retraction were thyroid eye disease (40%), trauma (15%), and congenital lid retraction (10%). While symptoms including tearing, ocular surface irritation and photophobia were noted in 24 (38%) patients, there were no documented cases of visual impairment secondary to eyelid retraction. Seventeen (27%) of the 62 patients required surgical intervention with 94% improvement. Discussion: In this 35 year cohort of pediatric eyelid retraction, approximately two-thirds were due to thyroid eye disease, trauma, or congenital eyelid retraction. No visual disturbances were noted and only 1 in 4 patients required corrective surgery. Conclusion: Pediatric eyelid retraction is a rare condition that is most likely associated with a thyroid disorder and no visual abnormalities. References: 1. Bartley GB.

I. duPont Hospital for Children 1600 Rockland Road, Wilmington, DE 19803 Introduction: To compare macular thickness and fixation behavior of amblyopic eyes, fellow eyes and normal eyes. Methods: Spectral-Domain OCT images of the macula were obtained from both eyes of each patient. Thickness measurements of the fovea and surrounding quadrants were recorded. When the fixation point and fovea did not coincide, shift distances between these two points were measured. Results: This study included 72 children with amblyopia (53 refractive and 16 strabismic or combined) and 47 children with normal examination. Eyes were placed in 3 groups: amblyopic (n = 73), fellow (n = 71) and normal (n = 94). One-way ANOVA was performed to compare retina thickness and no significant differences were found in the means across the groups. Pearson correlation tests indicate that the fixation shift distance has a negative relationship with visual acuity (R= -0.258, p= 0.005) and a positive relationship with stereopsis (R= 0.371, p=0.000). The mean shift distance for amblyopic eyes (272.85 ±466.62 µ) is significantly different from that for fellow eyes (40.58 ± 122.86, p = 0.000), and for normal eyes (16.84±69.33, p = 0.000). Discussion: The study found no detectable morphological difference in central retina thickness among amblyopic, fellow and normal eyes by spectral-domain OCT. Amblyopic eyes showed greater fixation shift distance than the fellow and normal eyes. Conclusion: The pathophysiology of amblyopia is not a structural imperfection in the retina. Fixation shift is present in refractive and strabismic amblyopia. Shift distance may be used as an indicator of visual function. 65 Poster 30 Saturday 9:55 - 10:55 am Poster 31 Saturday 9:55 - 10:55 am The Analysis of peripapillary retinal nerve fiber layer, macular, macular ganglion cell layer thicknesses in patients with monocular amblyopia using SD OCT Young Je Choi MD Ji Sung Jung MD Yong Ju Song MD Dae Hyun Kim MD, PhD Department of Ophthalmology, Chosun University Hospital Seoseok-dong, Dong-gu, Gwangju, Korea Introduction: To determine whether peripapillary retinal nerve fiber layer (PRNFL), macular, macular ganglion cell layer (MGCL) thicknesses differ in the amblyopic and normal eyes of unilateral amblyopic patients using spectral domain(SD) OCT. Methods: 160 eyes from 80 patients were researched. 17 patients with Strabismic amblyopia, control group of 17 patients with strabismic non-ambylopia, 23 patients with anisometropic ambylopia and control group of 23 patients with anisometropic nonambylopia. PRNFL, macular and MGCL thicknesses were obtained by SD-OCT, and the interocular thickness differences of each groups were analyzed. After treatments, amblyopic patients were evaluated in the changes of parameters. Results: Average PRNFL and MGCL of amblyopic eyes were thicker than normal eyes in total amblyopic 40 patients, but no differences in macular thicknesses (p<0.001,p<0.001,p=0.835). In 23 patients with anisometropic ambylopia, average PRNFL, MGCL of amblyopic eyes were thicker than normal eyes, but no differences in macular thicknesses (p=0.008,p<0.001,p=0.986). In 17 patients with strabismic ambylopia, only average PRNFL of amblyopic eyes were thicker than normal eyes, but no differences in macular, MGCL thicknesses (p=0.016, p=0.752, p=0.241). No interocular thickness difference was observed in control groups. After treatment, no change of parameter was observed in amblyopic eye. Discussion: In monocular amblyopia, there were differences of thicknesses in average PRNFL, MGCL between amblyopic eyes and normal eyes, but no differences in macular thicknesses. The differences in parameters among amblyopic patients however, remained same after the treatments. Conclusion: This study showed the inner retina is anatomically related with ambylopia in location and the outer retina has no relation with ambylopia. Poster 32 Saturday 9:55 - 10:55 am Distinctive Features of Microsaccades in Amblyopia and Refractive Blur Priyanka Kumar MD Aasef Shaikh MD, PhD Fatema Ghasia MD Cole Eye Institute, Cleveland Clinic Foundation Cleveland, Ohio, USA Introduction: Miniature eye movements like microsaccades shift the image on the fovea and counteract visual fading that occurs from neural adaptation. They are also thought to serve as an optimal sampling strategy while viewing complex visual scenes. The goal of the study was to assess the influence of a) simple visual blur induced by uncorrected refractive error (RE) and b) amblyopia on microsaccades. Methods: Ten healthy controls (HC) with RE and best-corrected vision of 20/20 and 22 amblyopes (mild =7;moderate= 10;severe=3) held their gaze on a stationary visual target. Eye movements were recorded using infrared video-oculography in a) HC with and without correction of RE and b) amblyopes during amblyopic and fellow eye viewing. Results: The microsaccade frequency in HC in corrected RE (median =2.3Hz) versus uncorrected RE (median=2.1Hz) was unchanged (Wilcoxin-rank test p=0.3). The microsaccade amplitude was higher in the uncorrected RE (median=0.8°) versus corrected RE (median=0.7°) (K-S test p<0.05). The percentage increase in amplitude correlated with the increase in uncorrected RE (linear regression R2=0.68, p=0.02). There was a systematic decrease in the frequency of microsaccades with increasing severity of amblyopia (median:mild = 1.8Hz; moderate = 1.4Hz; severe =0.5Hz, ANOVA p < 0.05). The microsaccade amplitude decreased with increasing severity of amblyopia (median:mild = 0.59°; moderate = 0.57°; severe =0.49°, ANOVA p<0.05). Discussion: Abnormal visual processing and circuitry reorganization results in altered microsaccades in amblyopia. These changes in fixational eye saccades cannot be explained by simple visual blur. Conclusion: Microsaccades can be an objective disease marker for amblyopia. 66 Objective compliance for atropine penalization treatment of amblyopic children Jingyun Wang Heather A Smith Kathryn M Haider Tina Damarjian Joshua Schliesser Derek T Sprunger Gavin J Roberts Dana L Donaldson Lyne Racette Daniel E Neely David A Plager Glick Eye Institute, Department of Ophthalmology, Indiana University School of Medicine Indianapolis, Indiana Poster 33 Saturday 9:55 - 10:55 am Introduction: Self-reported subjective compliance to atropine penalization ranges from 59% to 94%.[1-3] Objective measurement of compliance to atropine penalization has not been reported. This study aims to investigate objectively-measured compliance to atropine penalization treatment in amblyopic children. Methods: Twelve amblyopic children (3-8yr; 20/40-20/125 in the amblyopic eye) were enrolled. None were treated with atropine previously. We used Medication Event Monitoring System (MEMS) caps to objectively measure compliance. The MEMS caps are designed to record the time and date when the bottle was opened. Participants were also provided a calendar log to report compliance. They were scheduled for return visits at 4 and 12 weeks. Objective compliance was calculated as the ratio of MEMS weekly recording times to weekly regimen. Weekly regimen was based on physicians’ prescription, either twice per week or daily treatment. Results: At 4-weeks, objective compliance averaged 78% (range 57-100%), while subjective compliance was reported to be 84% (range 64-100%). At 12-weeks, the average objective compliance was 62% (range 41-100%), while subjective compliance was 84% (range 78100%). Interestingly, we found that the twice a week regimen had significantly higher objective compliance than the daily regimen (p=0.03). Discussion: Objective compliance with atropine instructions can be monitored with MEMS, which may facilitate more effective communication between clinicians and patients. Conclusion: Objective compliance with atropine penalization instructions decreases over time and varies with regimen. On average, subjective parental reporting of compliance is overestimated.

Amblyogenic factors in children with Neurofibromatosis Type 1 and their relation to the management of optic pathway gliomas. Eva Gajdosova, Susmito Biswas, Jane L Ashworth, Christopher I Lloyd Manchester Royal Eye Hospital, Manchester Academic Health Science Centre Manchester, United Kingdom Introduction: We wished to determine occurrence of amblyogenic factors in patients (pts.) with Neurofibromatosis Type 1 (NF1) and its relation to the management of the patients with optic pathway glioma (OPG). Methods: Retrospective case note review of pts. with NF1, age 0-18 years, referred to a newly set up NF1 clinic between Jan 2013 and July 2014 was performed. Age at referral, visual acuity, amblyogenic factors and presence of OPG was recorded and analysed by descriptive statistical methods. Results: We identified 56 pts. (25 females, 31 males), 5 pts. age <2 years, 25 pts. age =2<8 years, 26 pts. age =8<18 years. 27/56 pts. had at least one amblyogenic factor (significant ametropia or anisometropia 33%, ptosis 22%, strabismus 19% and strabismus with ametropia 22%, and early acquired nystagmus 4%). OPG was present in 46% pts. (26/56). Amblyogenic factors were identified in 16 pts. with OPG and 11 pts. without known OPG. There were 13 pts. under 8 years of age (6/16 with OPG) currently treated/ monitored for amblyopia. 4/6 pts. with OPG responded to amblyopia treatment. 2/16 did not respond and MRI scanning confirmed OPG. 1/16 developed papilloedema. In total there was 185 clinical appointments (average 3 app./pt., range 1-8). Discussion: In this small series 48% of pts. with NF1 had at least one amblyogenic factor. It is important to manage amblyopia in all patients undergoing screening for possible OPG or active monitoring because of OPG. Conclusion: Identification and treatment of amblyopia can possibly avert unnecessary use of chemotherapy in some pts. with OPG. 67 Poster 34 Saturday 9:55 - 10:55 am Poster 35 Saturday 9:55 - 10:55 am Severe corneal complications in children with blepharitis Diyaa Rachdan MD, MSc(Oxon), FRCOphth; M . Saad Khan; Asim Ali MD, FRCSC; Kamiar Mireskandari MBChB, FRCSEd, FRCOphth, PhD The Hospital for Sick Children, Toronto, Canada Introduction: Blepharitis is a chronic inflammation of lid margins that can lead to spectrum of ocular surface involvement such as phlyctenules, neovascularization, lipid deposits, scarring and irregular astigmatism. In children, these may compromise visual acuity and lead to amblyopia (1,2). In this study we report the visual outcome and corneal complications in pediatric blepharitis. Methods: Records of all children with blepharitis seen between 2006-13 were reviewed. Inclusion criteria were corneal lesions due to blepharitis (new vessels, inflammation, opacity, thinning, or lipid deposits) and follow-up of >/=6 months. Other ocular pathologies that might affect vision were excluded. Initial and final BCVA, medications and surgical procedures were recorded. Results: We identified 123 patients with mean age of 8.0 years (0.8 - 17.3) and followup of 30.4 months. Central pathology was present in 35% of all eyes and 60% of patients needed systemic antibiotics. Final visual acuity worse than 20/40 was associated with requiring corneal surgery (odds ratio: 4.69), presence of central pathology (OR; 3.05), and needing topical steroids (OR: 1.57). Eleven patients required surgical intervention. Discussion: Blepharokeratoconjunctivitis is a serious disease in children and may affects central cornea early and without peripheral lesions in a significant proportion of children. A heightened level of vigilance and early intervention is required to prevent vision loss. Conclusion: Pediatric BKC causes central scars in a third of eyes resulting in poor visual outcome and need for topical steroids and surgery. Lamellar corneal surgery restores media clarity but vision can be limited by amblyopia in half of cases. References: 1. Daniel S.

To date, there is little data addressing the effects of pediatric open globe trauma on long-term complications and visual prognosis, especially in younger pediatric patients. In this study we aim to correlate presentation and intervention with visual outcomes in young children at high risk for amblyopic complications. Methods: Retrospective chart review of patients age 0-6 years old presenting with open globe injury from 2000-2013. Results: Epidemiology revealed that subjects were 61% male with a mean age of 4.2 years old. Glass was the most common mechanism of injury. Associated findings included uveal prolapse (93%), choroidal detachment (39%), hyphema (32%), and retinal detachment (11%). Cataract (p<0.005) and a wound greater than 6 mm (p<0.05) were found to be associated with a final visual acuity worse than 20/40. There was a statistically significant improvement in visual acuity in patients who started patching less than 20 days after injury (p<0.05). Discussion: Patients age 0-6 years with open globe injuries present a unique population with different risk factors for poor outcome. We propose a novel algorithm for predicting indicators of poor visual outcome (less than 20/40) with a 92% sensitivity and 81% specificity. Conclusion: A different prognostic algorithm that does not rely on presenting visual acuity is needed in young children. Factors that increase amblyopia are more indicative of poor outcome than in other age groups. Patching immediately after surgery correlates with improved outcomes. 68 Clinical Application of the ATOM2 Study: Atropine 0.01% Significantly Reduces Childhood Myopic Progression Tiana Y Clark Robert A Clark MD Family Eye Medical Group, Long Beach, CA Poster 37 Saturday 9:55 - 10:55 am Introduction: Atropine 0.01% drops have been shown to slow childhood myopic progression in selected populations. We studied its effects on an ethnically diverse population over a broad range of myopia. Methods: A retrospective case-control study was performed on 56 children (6-15 years) with initial myopic spherical equivalents from -0.25 to -8.00. The primary measure was the rate of myopic progression per year. Secondary measures were the proportions of subjects with minimal or rapid myopic progression and atropine-related side effects. Results: The average initial age (10.2 years) and refraction (-2.0 D) were identical between groups. After 1.1±0.3 years follow up, atropine subjects had significantly lower rates of myopic progression (-0.1±0.6 D/yr) than controls (-0.6±0.4 D/yr) (p=0.001), including 20/28 (71%) with myopic progression ≤ -0.25 D/yr versus only 5/28 (18%) controls. Three atropine and four control subjects had myopic progression ≥ -1.00 D/yr. For subjects with low initial myopia (≤-1.00 D), 7/9 (78%) atropine subjects had plano or slightly hyperopic refractive changes after one year, while 9/9 (100%) controls were more myopic. Only three atropine subjects complained of intermittent blur or light sensitivity, not symptomatic enough to discontinue treatment. Discussion: Atropine 0.01% significantly reduced the rate of myopic progression over one year with minimal side effects. It appears most effective in subjects with low initial myopia and may not control rapid myopic progression in some patients. Conclusion: Atropine 0.01% reduces childhood myopic progression and should be considered for lower levels of myopia. Stronger concentrations of atropine may be required to slow rapid myopic progression. References: 1. Chua W, Balakrishnan V, Chan Y, Ling Y, Quah B, Tan D.

Excimer Laser Refractive Surgery Outcomes in 405 Children and Adolescents Nicholas Faron James Hoekel Lawrence Tychsen St. Louis Children’s Hospital at Washington University Medical Center St. Louis, MO Introduction: Reports of using the excimer laser to treat myopic & hyperopic refractive errors in children have been limited to case reports. We analyze outcomes in 405 ametropic children who were noncompliant with spectacles or contact lenses. Methods: Clinical outcome data were collated prospectively in 231 myopic children (371 eyes) and 174 hyperopic children (283 eyes) treated for isoametropic or anisometropic refractive error using excimer laser keratectomy. 86% of the patients had a preexisting neurobehavioral disorder and/or visuomotor co-morbidities. The mean age at refractive surgery was 11.3 years (range 3 to 20); mean follow-up was 3.6 years (range 1-13 years). Results: Myopic spherical refractive error averaged -4.91±3.08D (range -0.50 to -14.50) and hyperopic spherical refractive error averaged 3.84±1.51D (range 0.50 to 6.75). 96% of myopic & 91% of hyperopic eyes were corrected to within ±1D of their target value. After 5 years, refractive regression was -0.10D/yr in myopes and +0.10D/yr in hyperopes. Myopic & hyperopic BCVA improved 0.12 logMAR & 0.08 logMAR; UCVA improved 0.44 logMAR and 0.26 logMAR, respectively. 91% of myopic & hyperopic eyes treated with mitomycin-C had no haze (no child with postoperative haze lost BCVA). 51% of children treated had a gain in at least one level of binocular fusion. Retreatment was conducted in 1.5% of the treated eyes. Discussion: Refractive error and visual acuity substantially improved from preoperative measurements. Conclusion: Excimer laser surgery is an effective means for improving visual function and quality of life in moderately ametropic children who have difficulties wearing spectacles. 69 Poster 38 Saturday 9:55 - 10:55 am Poster 39 Saturday 9:55 - 10:55 am Long-Term Developmental Improvement in Children with Neurobehavioral Disorders Following Photorefractive Keratectomy for Bilateral Isoametropic Amblyopia Charity H Grannis MD Lingkun Kong MD, PhD Bryan T Whitlow MS Catherine Achim MD Daniel Wang MD Mitchell Weikert MD David Coats MD Evelyn A Paysse MD Baylor College of Medicine, Houston, TX Introduction: To assess long-term impact of PRK correction of severe isoametropia on the development of children with neurobehavioral problems. Methods: This is a prospective, interventional case series. Children with neurobehavioral disorders and severe isoametropia unwilling to use refractive correction underwent PRK surgery. Developmental status was evaluated preoperatively and at 6, 12, 24 and 36 months posoperatively. The main outcome measure was developmental quotient (DQ). Secondary outcome measures were uncorrected visual acuity and cycloplegic refraction. Results: Fifteen children aged 2-8 years were included. Twelve were myopic (-9.8±3.9D), two hyperopic (+5.8 ± 0.4D) and one astigmatic (+3.5D). Significant DQ improvement was found in receptive, expressive and written communication (p=0.001, 0.05, 0.04 respectively), domestic daily living skills (p=0.03) and interpersonal socialization skills (p=0.02) for the first 12 months, which then plateaued. Improvement in visual perception and motor coordination occurred at 36 months postoperatively. Uncorrected visual acuity improved after PRK (logMAR +1.25 ± 0.6 to +0.55 ±0.4). Mean spherical equivalent refractive error was significantly improved at 6 and 36 months at -0.6 ± 1.5D and -1.7 ± 2.2D for the myopic group, +1.4 ± 1.1D and +2.0 ± 1.1D for hyperopic group and +1.6 ± 0.5D and +2.4 ± 0.2D for the astigmatic patient. Discussion: Long-term improvement in development, visual acuity and refractive error was found in children with neurobehavioral disorders following PRK. Conclusion: PRK can enhance the quality of life of children with neurobehavioral disorders with severe isoametropia. Poster 40 Saturday 9:55 - 10:55 am A Cost Comparison Study between Recommendations from the American Optometric Association and Recommendations from the American Association for Pediatric Ophthalmology and Strabismus on the Correction of Hyperopia in Children Philip Niles Ali R Cohen Scott A Larson Richard J Olson William E Scott University of Iowa Department of Ophthalmology and Visual Sciences, Iowa City, IA Introduction: There are many different recommendations to guide ophthalmologists and optometrists when prescribing hyperopic correction in children. This study examines the difference in healthcare costs between the recommendations from the American Optometric Association (AOA) and the recommendations from the American Association for Pediatric Ophthalmology and Strabismus (AAPOS). Methods: Race-specific population data was retrieved from 2010 US Census Bureau records for children ages 2- to 6-years-old. The prevalence of children for each dioptric refraction was calculated using race- and age- specific data from the Baltimore Pediatric Eye Disease Study. The number of children who would meet AOA and AAPOS prescription recommendations was determined. AOA recommends correcting for +3.00D or more of hyperopia for children up to age 10-years-old. AAPOS recommends correcting for +4.00D or more of hyperopia in 2- to 7-year-old children[M1] . The total one-time cost of each association’s recommendations was then determined by multiplying the number of children who would receive spectacle correction[M2] by the median cost of pediatric spectacles, which was determined from a 2013 industry survey of 171 independent optical retailers. The cost of glasses wear was conservatively limited to the initial purchase price of one pair of spectacles. Results: There were 21,558,917 American children between the ages of 2- and 6-years-old, inclusively. There was an expected prevalence of: 1,225,070 children with a refraction of +3.00D but less than +4.00D, 351,311 children with +4.00D but less than +5.00D, and 410,688 children with +5D or greater. The median cost for pediatric frames is $125 and the median cost for lenses is $120. The total cost would be $486.8 million using AOA recommendations and $186.7 million using AAPOS recommendations. AAPOS recommendations would decrease healthcare costs by $300.1 million (62%) compared to AOA recommendations. Discussion: Different recommendations for hyperopic correction between AOA and AAPOS lead to a significant cost difference on hyperopic correction in 2- to 6-year-old children. This difference would be even larger if the cost of glasses wear accounted for the need for subsequent glasses and spectacle repair. Conclusion: There is a large cost difference between AOA’s and AAPOS’s hyperopic correction recommendations. The cost of healthcare recommendations should be taken into consideration when making healthcare policy. References: 1. American Optometric Association.

The purpose of this study is to elucidate the vision screening experience of school nurses in Colorado. Methods: A questionnaire was sent to 774 members of the Colorado Department of Education School Nurse listserv in 2014. Results: 218 of 774 (28%) questionnaires were completed. 88 % of the respondents were public school nurses. Discussion: The majority of respondents followed the vision screening and referral guidelines recommended by AAPOS/AAO/AAP and the Colorado Department of Education(1-2). Most nurses did not use instrument based screening. Screening accuracy may be reduced since less than 1% of respondents used occlusive patches and 78% allowed the child to hold the occluder during monocular vision testing. Reported screening challenges included: poor student cooperation/inability to screen, inadequate testing space & lighting, insufficient personnel and poor parental compliance with referrals. Conclusion: Colorado school nurses report significant challenges in the implementation of vision screening programs. Poor parental/guardian compliance with referrals is a significant threat to the effectiveness of vision screening(3). References: 1.

Vision First: a Comprehensive Screening Program for Young Children Joseph F Griffith MD Heather C Cimino OD Rhonda Wilson MA Mayme Patthoff Daniel F Martin MD Elias I Traboulsi MD Cole Eye Institute, Cleveland, Ohio Introduction: Recent vision screening research has focused on technology-based approaches to identify preschool children with amblyopia risk factors. Here we present data derived from Vision First, an established program for vision screening and eye examinations in children in the amblyogenic age group. Methods: Children aged 4-8 years underwent screening by an ophthalmic technician and/or optometrist in a customized van that visits elementary schools in Cleveland, Ohio. Examinations included assessment of monocular near and distance visual acuity, stereoacuity, alignment, extraocular movements, pupils, color vision (males only), and external abnormalities. Children meeting the 2003 American Academy of Pediatrics vision screening failure criteria underwent cycloplegic retinoscopy and ophthalmoscopy on site by the optometrist and were dispensed glasses. Those with more than simple errors of refraction were referred to a pediatric ophthalmologist. Results: 63,841 examinations were performed between 2002 and 2014. 6,386 (10.0%) of children met one or more failure criteria, 5,355 (8.39%) were prescribed glasses, 873 (1.37%) had amblyopia, and 1125 (1.76%) had strabismus. The cost per child was approximately $26.00, excluding initial capital expenses and the cost of dispensing glasses. Discussion: The Vision First model targets 4-8 year-olds and employs eye care professionals to use gold-standard examination techniques. This model ensures treatment of errors of refraction and referral of those with amblyopia and strabismus. Conclusion: Amblyopia, strabismus, and refractive errors are common pediatric eye diseases in Cleveland, OH and a van-based model has been effective in screening and treating young children in underserved communities. 71 Poster 42 Saturday 9:55 - 10:55 am Poster 43 Saturday 9:55 - 10:55 am A new computer-based pediatric vision-screening test David A Leske MS Sarah R Hatt DBO Tomohiko Yamada OD, FAAO Pamela S Moke MSPH Nick L Parrucci BSCS J. Jeffrey Reese BA James B Ruben MD Jonathan M Holmes BM, BCh Mayo Clinic, Rochester, Minnesota Introduction: We developed and validated a new Windows-based visual acuity screening test (the Jaeb Visual Acuity Screener - JVAS) for age-specific vision screening in schools and physician offices, presenting 2 large optotypes and up to 5 screening optotypes at age-specific thresholds. Methods: We screened 187 children ages 3 to <8 years who presented to an eye clinic for a complete eye exam. We evaluated the ability of the JVAS to detect gold-standard failures, based on 2013 AAPOS screening criteria and published age-normal visual acuity thresholds. Three JVAS screening paradigms were evaluated (3 of 4 correct, 3 of 5 correct, or 4 of 5 correct to pass). Results: Testability of the JVAS was 100%. 68 of 187 children met gold-standard failure criteria. 47% failed for uncorrected refractive error with reduced visual acuity, 10% for unilateral amblyopia, 13% for bilateral amblyopia, 15% for unexplained reduced visual acuity, 12% for refractive error without reduced visual acuity, and 3% for alignment alone. Depending on JVAS screening paradigm, JVAS sensitivity ranged from 88% to 91% and specificity ranged from 73% to 86%. Positive predictive value ranged from 66% to 78% and negative predictive value ranged from 93% to 94%. Requiring 3 correct out of 5 presentations resulted in the best combination of sensitivity and specificity (88% and 86%). Discussion: The JVAS is an effective screening method for reduced visual acuity due to refractive error and amblyopia. Conclusion: The JVAS optotype vision screening application is available free of charge and has the potential for wide use in schools and physician offices. Poster 44 Saturday 9:55 - 10:55 am Visual Outcomes of Patients with Congenital Cataracts and Sensory Nystagmus Charlene H Crockett MD Lingkun Kong MD, PhD Kathryn A Camero Kimberly G Yen MD Texas Children’s Hospital / Baylor College of Medicine Houston, Texas Introduction: To evaluate the visual outcomes of patients presenting with bilateral congenital cataracts and sensory nystagmus. Methods: Sixteen patients less than 18 years of age who underwent cataract surgery between 9/2002 and 2/2014 were included. Data collected included best-corrected postoperative visual acuity (BCVA), etiology of cataracts, associated systemic/ocular conditions, status of strabismus, surgical complications, and characteristics of the nystagmus. Results: All patients had bilateral congenital cataracts and sensory nystagmus at time of presentation. Age at diagnosis was 7.9 ± 10.1 months. Age at time of surgery was 8.5 ± 10.1 months. Average length of follow up was 32.8 ± 36.2 months. Thirteen patients were left aphakic while 3 patients received intraocular lenses bilaterally. 8/16 patients had fix and follow visual acuity at last visit; of the remaining patients, six of 8 (75%) had BCVA > 20/60 in at least one eye. Nystagmus was not observed in 4/16 patients (25%) at last follow up. Patients without associated ocular conditions, such as strabmismus, microcornea, amblyopia, or microphthalmos, were more likely to have resolution of nystagmus (p=0.02). Better visual acuity did not necessarily correlate with resolution of the nystagmus. Discussion: The presence of sensory nystagmus does not preclude good visual outcomes in patients with congenital cataracts. Conclusion: The presence of sensory nystagmus should not affect the decision to perform timely cataract surgery for congenital cataracts as favorable visual outcomes are still possible. Patients without ocular comobidities have a higher chance of resolution of the nystagmus. 72 Axial growth and clinical outcomes of children operated for bilateral ectopia lentis Jennifer D Davidson MD M. Edward Wilson MD Rupal H Trivedi MD Leah A Owen MD Dina Sabry Poster 45 Saturday 9:55 - 10:55 am Medical University of South Carolina Storm Eye Institute Charleston, SC Introduction: To report outcomes of children operated for bilateral ectopia lentis. Methods: Charts of 94 eyes from patients who underwent anterior lensectomy for ectopia lentis by one surgeon were reviewed. Pre and postoperative best corrected visual acuity (BCVA), axial length (AL) at surgery and follow up, etiology of ectopia lentis, and complications were reviewed. We excluded unilateral surgery, <3 months of follow-up and age at last follow-up <4 years. Treatment outcomes (aphakia vs. IOL) were not included due to confounding factors. Age at the time of lensectomy, group 1 = < 4yrs, group 2 = 4-8yrs and group 3 = > 8yrs. Results: 70 eyes of 35 patients (21 Male) met inclusion criteria. Average follow-up was 5.3 yrs. 19 patients had a diagnosis of Marfan syndrome. Average age at surgery was 6.9yrs (SD 4.4), (3 mo to 18.8 yrs), 7.8yrs for Marfan and 5.9yrs for non-Marfan. Axial growth was 0.5, 0.2 and 0.1 mm/yr for the three groups respectively. 0.2mm/yr for Marfan and 0.28mm/yr for non-Marfan. 3 eyes had retinal detachment: all with marfan diagnosis. 1 in group 1; 2 in group 2. 10 had glaucoma: 2 Marfan; 8 non-Marfan, 7 in group 1, 1 in group 2, 2 group 3. The median post-op BCVA was 20/40 for Marfan and 20/30 for nonMarfan and 20/40, 20/30 and 20/30 for the three age groups respectively. Conclusion: Average age of surgery was younger in patients without Marfan syndrome. Glaucoma was more common with younger age at surgery and in the non-Marfan group. Retinal detachment was more common in patients with Marfan syndrome. Visual outcomes were similar in all groups regardless of age at surgery or etiology.

J AAPOS 2014;18:140-146 Baseline Characteristics of the Infant Aphakia Treatment Study Population: How well can they predict recognition visual acuity at 4.5 years? E Eugenie Hartmann PhD Michael J Lynn Scott R Lambert MD University of Alabama at Birmingham Birmingham, Alabama Introduction: The intensive protocol for treatment of monocular congenital/infantile cataracts, which includes surgery, optical correction and years of occlusion therapy, is a significant financial and emotional investment for families and clinicians. The purpose of our present analysis was to identify patient baseline characteristics that predict recognition acuity at 4.5 years of age in the Infant Aphakia Treatment Study. Methods: A total of 114 infants were enrolled in the Infant Aphakia Treatment Study. All participants underwent cataract surgery between 1 and 7 months of age. Recognition acuity was assessed monocularly using the Amblyopia Treatment Study HOTV testing protocol at 4.5 years of age. Participant baseline characteristics were specified and the relationship between these factors and visual acuity at 4.5 years was evaluated using linear regression. Results: Characteristics evaluated included 1) Characteristics of the treated eye; 2) Physiological characteristics of infant and 3) Sociological characteristics of family. Only age at surgery and presence of private insurance were individually associated with visual acuity. The multivariate analysis demonstrated that only the availability of private insurance was statistically significant and accounted for 12% of the variance. Discussion: This analysis concurs with previous studies that early surgery is important for good visual outcomes in patients with unilateral congenital cataracts. Previously we found an association between private insurance and adherence to patching, which may in part explain the present findings 1. Conclusion: However, the multivariate analysis accounts for only 12% of the variance, suggesting that predicting visual outcome for these patients is complicated at best, requiring more information than is available at baseline.

We report endothelial cell (EC) counts of IATS patients at the 5-year exam. Methods: Non-contact specular microscopy was performed and endothelial cell density, coefficient of variation (CV), and percent hexagonal cells were measured. Fellow eyes served as controls. Mean differences between treated and fellow eyes of CT and IOL groups were compared with an independent groups t test. Results: 80 patients were included (38 CTL, 42 IOL). Mean cell density of treated eyes was 3921 and 3445 cells/mm2 for the CTL and IOL groups, respectively and 3495 and 3487 for corresponding controls (p=0.0009). Mean CV was 27 and 25 for CTL and IOL and 24 for both controls (p=0.069). Mean percent hexagonal cells was 72% and 73% for CTL and IOL groups and 76% for both controls (p=0.30). Discussion: Although IOL patients may appear worse as EC cell counts are lower, these results may be paradoxical. IOL cell counts are similar to the control groups. More cells may be present in CTL patients due to a greater CV. Corneal polymegathism is a condition where endothelial cells form rosettes of smaller, less regular cells. Thus, more cells are counted in a given area. Polymegathism may result from oxygen deprivation associated with extended wear CTL use. Conclusion: Cataract extraction during infancy was not associated with a reduced EC count in treated compared to fellow eyes. Poster 48 Saturday 9:55 - 10:55 am Incidence, natural history, and outcomes of traumatic cataract after hyphema associated with blunt ocular trauma in children Ankoor S Shah MD, PhD and Olumuyiwa T Adebona MBChB, MPH Boston Children’s Hospital and Harvard Medical School Boston, MA, USA Introduction: Hyphema is a common manifestation of blunt ocular trauma in children. Traumatic cataracts are a known complication, but their incidence, natural history, and outcomes are sparsely reported. This study addresses these gaps in the literature leading to better patient counseling and management. Methods: A retrospective, cohort study of patients at a single, tertiary-care, pediatric hospital was performed. Patients less than 18 years of age presenting for blunt ocular trauma with hyphema between 2002 and 2011 were included. The mechanism of trauma, socio-demographic information, and ophthalmic examination data were abstracted. Results: Seventeen of 128 (13%) developed cataract at a median of 14 days (range 2-113) after injury. The median age was 9 years (range 4-17). Thirteen were male. High-velocity projectile objects were implicated in 9/17 (53%) of cases. Greater than 3+ anterior chamber cells occurred in 10/17 (58%). All cataracts were anterior or posterior capsular cataracts on initial diagnosis. The median duration of follow-up was 29 months and ranged from 5-97 months. Median visual acuity was 20/245 initially and 20/25 at final visit (p=0.0001). Seven patients required surgery at a median of 54 days (range 20-698). Discussion: Cataract after blunt ocular trauma with hyphema occurs in the pediatric population commonly and typically presents early after the injury. These cases are associated with good visual outcomes. Approximately ~40% of cases require surgery. Conclusion: Traumatic cataracts after blunt ocular injury with hyphema typically occur within 2 weeks, and they are generally associated with good outcomes. 74 A new diagnostic approach to children with cataract caused by metabolic disease Rachel L Gillespie Jane Ashworth Susmito Biswas Simon C Ramsden Jill Clayton-Smith I. Chris Lloyd Graeme C Black Manchester Centre for Genomic Medicine, The University of Manchester Manchester, UK Poster 49 Saturday 9:55 - 10:55 am Introduction: Inborn errors of metabolism account for a subset of congenital cataract (CC) cases. For some of these children, therapeutic intervention to prevent disease progression may be possible. As such, early diagnosis is critical. Genetic heterogeneity and technological limitations have traditionally precluded diagnosis and a battery of complicated biochemical tests are often ordered to try to reach a precise diagnosis. Advanced next generation sequencing (NGS) methodologies are currently revolutionizing the use of genomic information and can guide a personalized approach to assessing prognosis, management and treatment. Methods: We have successfully implemented an NGS target enrichment to screen, in parallel, 115 genes associated with all forms of CC. Results: We have determined the genetic cause of CC in 75% of individuals within our cohort.[1] 18% of identified mutations cause CC as a result of an underlying metabolic disease, indicating that these conditions may be more prevalent than the literature suggests and under diagnosed due to lack of awareness. Six metabolic conditions were identified, including lathosterolosis, cerebrotendinous xanthomatosis, peroxisomal biogenesis disorder 14B, a new cholesterol biosynthesis disorder, GLUT1 deficiency and galactokinase deficiency. Discussion: Our results show that the use of targeted-NGS as a frontline test for the diagnosis of CC not only reduces the need for the battery of complicated tests typically used in the pre-genomic era, but is also an efficient method for diagnosing metabolic conditions complicated by CC. Conclusion: Targeted NGS as a frontline test for CC will improve clinical outcomes as a result of subsequent implementation of more precise medical intervention. References: 1.

Rebound tonometry over an air-filled anterior chamber in the supine child after intraocular surgery Ryan Davis Kim Jiramongkolchai Evan Silverstein Sharon F Freedman Duke Eye Center Durham, North Carolina Introduction: To evaluate the usefulness/accuracy of a position-independent rebound tonometer (Icare Pro) to measure IOP intraoperatively in pediatric eyes with intracameral air, by comparing with applanation tonometry(TonopenXL) as gold standard. Methods: Ongoing prospective, IRB-approved study of sequential children having intraocular surgery. IOP was measured immediately following general anesthesia induction, by both Icare PRO rebound tonometry (Rt, Icare Finland Oy,Helsinki) and TonopenXL tonometry (At, Medtronic,Inc,Minneapolis,MN), with instrument order randomized, in the supine child’s eye. At intraocular surgery completion, and after standard placement of intracameral air, IOP was measured with Icare PRO and TonopenXL (same order as pre-operatively). Analysis included IOP (by At and Rt) and Bland-Altman analysis (mean difference[change in IOP(At- Rt)], 95%Confidence Interval[CI]). Results: Indications for surgery (26 eyes enrolled to date) included: glaucoma(15), cataract(10), and post-trauma secondary IOL(1). Mean pre-operative IOP (n=26) by At vs. Rt was 21.50+8.48 vs. 17.93 + 6.56 mmHg, respectively (p=0.002). Mean IOP over intracameral air at surgery conclusion by At (n=25) vs Rt (n=26) was 13.48+5.43 vs. 13.17+5.28 mmHg, respectively (p=0.86). One eye had post-operative IOP unrecordable by At but 7.9mmHg by Rt. Bland-Altman analysis showed: pre-operative mean change in IOP(At- Rt)=3.57mmHg [CI=1.49;5.65]; vs. post-operative mean change in IOP(At- Rt)=0.10mmHg [CI=-1.091;1.291]. Discussion: Position-independent rebound tonometry (IcarePRO) easily measured IOP in supine children’s eyes pre- and post-intraocular surgery, and correlated well with applanation (TonopenXL), especially post-operatively over intracameral air. In eyes with low IOP, rebound tonometry was more readily obtained than applanation. Conclusion: Position independent rebound tonometry may be useful in monitoring IOP immediately following intraocular surgery even with intracameral air. 75 Poster 50 Saturday 9:55 - 10:55 am Poster 51 Saturday 9:55 - 10:55 am Longitudinal Evaluation of Intraocular Pressure in Pediatric Hyphema: A New Paradigm for Followup Charlotte Gore Olumuyiwa Adebona Ankoor S Shah Children’s Hospital Boston , Harvard Medical School Boston, Massachusetts Introduction: The initial follow-up for pediatric hyphema focuses on identifying increased intraocular pressure (IOP). The standard follow-up is commonly prescribed as daily appointments for 3 days and a 1-week visit. This is a costly endeavor. We perform a longitudinal evaluation of IOP trends in pediatric hyphema patients to develop a more tailored follow-up plan. Methods: We performed a retrospective chart review of all pediatric patients with traumatic hyphema during an 11-year period. Raised IOP was defined as IOP>22 mmHg within 90 days of injury. Results: A total of 133 cases were identified with median follow-up time of 15 months. Forty-three (32%) developed ocular hypertension and their median time to IOP peak was 6 days (range 0-35). The median IOP was 29 mmHg (range 22-57) for patients who developed ocular hypertension and 19 mmHg (range 10-21) for those who did not. Having a past ocular history and sustaining a concurrent intraocular injury were significantly correlated with development of ocular hypertension. The amount of anterior chamber hyphema did not correlate to ocular hypertension. Discussion: Ocular hypertension develops at a median of 6-days after injury. Based on these data, one could argue that daily IOP checks may not be necessary and the followup visits can be modified by presentation clinical exam. Conclusion: We propose a new paradigm of follow-up for pediatric hyphema patients. For those with ocular co-morbidities at presentation, we suggest follow-up at 1-, 3-, and 7-days post injury. And for those without, we suggest follow-up at 1- and 7-days post injury. Poster 52 Saturday 9:55 - 10:55 am Surgical outcomes using a modified Anderson-Kestenbaum operation Charline S Boente Faruk H Orge Beth J Colon Department of Ophthalmology and Visual Sciences, Case Western Reserve University and University Hospitals Rainbow Babies and Children’s Hospital Cleveland, OH Introduction: A variety of modifications and augmentations to the Anderson-Kestenbaum operation for null point nystagmus have been developed. Results have been varied, frequently resulting in residual head turn. We discuss the surgical results of a unique modification originally introduced in 1979 by Flynn and Dell’Osso using equal numbers of recession and resection (e.g. 5-5-5-5 mm), directly correlating with the gaze angle of the anomalous head positioning. Methods: This study was conducted as a retrospective case series chart review of six patients seen in our clinic between January 2008 and September 2013. Patients who underwent surgical correction for nystagmus using equal numbers of recession and resection were included in the study, and pre- and post-operative data from clinic visits were reviewed, including eye movement recording data, if available. Results: Post-operative measurements showed minimal residual to resolved anomalous head positioning in all subjects. In addition, decreased nystagmus intensity and improved visual acuity measurements in primary gaze were observed without any additional alignment deviations or ocular motility restrictions. Discussion: The major advantage to the surgeon is the ease of pre-surgical planning that this approach affords. The challenge continues to rest on understanding the relationship between the neurological control system and the mechanical forces of extraocular muscles for null point nystagmus. Conclusion: The modified Anderson-Kestenbaum operation using equal numbers of recession and resection can provide a simple and efficient alternative for surgical planning, and has demonstrated favorable outcomes of resolved anomalous head positioning and decreased nystagmus intensity in our series of patients. 76 Two types of head oscillations in Infantile Nystagmus Syndrome Fatema F Ghasia MD Aasef G Shaikh MD PhD Cole Eye Institute, Cleveland Clinic Cleveland OH Poster 53 Saturday 9:55 - 10:55 am Introduction: Infantile Nystagmus Syndrome (INS) is a common congenital disorder of eye movement. Head oscillations have been rarely described in INS patients. We quantitatively characterized eye and head oscillations in INS patients. Methods: Video-based tracker (Eyelink 1000) was used to record eye and head movements simultaneously in ten INS patients (4= Idiopathic, 6= oculocutaneous albinism). Results: Two types of head oscillations were present. The first type was irregular with frequency between 1-3 Hz. The second type was regular and sinusoidal with a frequency range of 5-8 Hz. Irregular low-frequency oscillations were seen in all INS patients, but the high-frequency oscillations were only present in seven of them. High-frequency oscillations were episodic whereas irregular low-frequency oscillations were always present. There was no correlation between peak velocity of the head oscillations and eye velocity of nystagmus to suggest the influence of head oscillations on foveation. Discussion: We found two types of head oscillations in INS patients. Lack of correlation between the foveation period of nystagmus and peak head velocity during oscillations suggests, in our cohort that the head oscillations were a co-existing pathological phenomenon rather than a compensatory mechanism to improve the visual acuity. Conclusion: Head holding disorders are common in patients with Infantile Nystagmus Syndrome and likely represent a pathologic tremor. They are present in patients with idiopathic infantile nystagmus syndrome as well as those with afferent visual pathway abnormalities. Clinicopathological findings in abusive head trauma: analysis of 110 infant autopsy eyes Kelly H Unkrich MD Mark P Breazzano MD Ann E Barker-Griffith MD State University of New York, Upstate Medical University Syracuse, New York Introduction: To investigate the histopathology in a large series of autopsy eyes from children with abusive head trauma (AHT). Methods: Design: Retrospective case-control series. Methods: One-hundred-and-ten autopsy eyes from fifty-five cases examined at an academic tertiary referral center over twenty-one years were tabulated for histopathology: subdural hemorrhage, intrascleral hemorrhage, any retinal hemorrhage, ora-extended hemorrhage, cherry hemorrhage, perimacular ridge and internal limiting membrane (ILM) tear. Select tissues with cherry hemorrhage were further examined by transmission electron microscopy (TEM). Results: Sixty eyes were identified as ‘AHT’ (cases), forty-six ‘alternative cause’ (controls) and four ‘AHT survivor’. AHT was legally verified or confirmed by confession for all cases except one. All ocular pathology was similar or more frequent in AHT infants younger than 16 months of age. A perimacular ridge was found in 42% and cherry hemorrhage in 40% of AHT eyes, all having an ILM tear. Both AHT survivor cases demonstrated severe optic nerve atrophy and macular ganglion cell loss. Conclusion: Younger infants may be even more susceptible to damage from vitreomacular traction by rotational and/or acceleration-deceleration forces. Identifying cherry hemorrhages may aid AHT diagnosis. Survivor AHT pathology demonstrates unique, irreversible macular and optic nerve damage.

Douglas Fredrick M.D. Stanford University Palo Alto, CA Introduction: To identify epidemiologic trends in nonpowder gun-related pediatric eye injuries and to determine factors associated with severe injury requiring hospital admission. Methods: US emergency department data on pediatric eye injuries between 2002 through 2012 were reviewed using the National Electronic Injury Surveillance System. Literature review was conducted to determine trends in visual outcomes after treatment and use of eye protection. Results: In 2012, roughly 3,161 children were treated in US emergency departments for nonpowder gun-related eye injuries. Since 2010, rates of severe nonpowder gun pediatric eye injury have increased by over 500% (P = 0.039). Specifically, while rates of hospital admission due to paintball gun eye injury have dropped precipitously (P = 0.0077), rates of admissions for air gun eye injuries have increased by over 600% since 2010 (P = 0.033). Children sustaining eye injury due to air guns are more likely to be diagnosed and admitted with foreign body or ocular puncture injury. Roughly 28% of documented cases of airsoft or BB gun-related injury had visual acuity worse than 20/50 after initial treatment. Over 98% of injuries occurred without eye protection. Discussion: Air guns, and not paintball guns, are rising in popularity, and account for the majority of pediatric eye injuries requiring hospital admission. The majority of eye injuries occur without ocular protection, and may lead to permanent eye injury. Conclusion: Air guns can cause severe, yet preventable, eye injury among the pediatric population. Increasing regulations for eye protection, sales, and usage of air guns are needed to prevent serious pediatric eye injuries. Poster 56 Saturday 9:55 - 10:55 am Residency Factors that Affect Residents’ Pursuit of Pediatric Ophthalmology Elizabeth S John BA Airaj F Fasiuddin MD Bertha A Nash MA University of Central Florida College of Medicine Orlando, FL Introduction: While the pediatric population comprises 26.7% of our population (1), in 2013 only 62% of pediatric ophthalmology (PO) fellowship positions were filled (2), there is an urgent need to understand what factors influence residents’ decisions to pursue a PO fellowship. Methods: A 16-item questionnaire about the structure of PO rotations, perceptions of faculty and experiences in residency programs was distributed to current ophthalmology residents in the U.S. Results: Ninety-six responses were received; 60% of the participants reported ‘no interest in working with children’ or ‘no interest in pediatric ophthalmology’, thus excluded from analysis (N = 38). Five residents (13%) were definitely pursuing pediatric ophthalmology: All (100%) perceived faculty in their program as interested in teaching, felt they had adequate exposure to strabismus surgery, and had spent 2-6 months in pediatric ophthalmology rotations. Further analysis revealed a positive relationship between time in rotations and feelings of adequate exposure (r = .34, p < .05) and a non-significant association between an ‘interest in pediatric ophthalmology’ and ‘pursuing a fellowship’ (X2= 2.452, p = 0.11). Discussion: The role of a mentor and surgical exposure were important to residents choosing a fellowship in pediatric ophthalmology, suggesting that an interest in the practice of ophthalmology, is not the only deciding factor. Conclusion: As the pediatric population is increasing (3), and the number of pediatric ophthalmologist decreasing, it has become more important to understand what residency program directors can do to fill this gap. In this study, we found that mentorships and exposure are factors worth addressing in existing curriculum. References: 1. U.S. Census Bureau. Age and Sex Composition in the United States: 2012.

Methods: Retrospective record of 10 cases, 2 to 10 years of age, who developed lash ptosis on using patches during management of amblyopia. No one had previous history of lid disorder or eye allergy. They patched 2 to 8 hours daily for one to 4 months. Eight patients have continued visiting us 2 months after patch discontinuation. Results: Lash ptosis had been noticed within one month of patching. Out of eight patients, who discontinued patching, four (50%) showed improvement of lash ptosis. Improvement showed direct relation to time of exposure to patching. Discussion: I have not found papers talking about patching as a cause of lash tosis. Conclusion: Lash ptosis should be considered as a possible complication of patching. It is usually reversible. Shorter period of patching gives shorter period of recovery. Amblyopia Occlusion Therapy Compliance: AmblyzTM Liquid Crystal Glasses Versus Traditional Adhesive Patches Tina Damarjian MD, Heather A. Smith MD, Daniel E. Neely MD, Jingyun Wang, PhD, Jay Galli, Jessica Kovarik MD, James Bowsher MD, Joshua Schliesser MD, Kathryn M. Haider MD, Gavin J. Roberts MD, Dana Donaldson OD, Derek Sprunger MD, David A. Plager MD Glick Eye Institute, Department of Ophthalmology, Indiana University School of Medicine Indianapolis, Indiana Introduction: Amblyopia treatment with adhesive occlusion patches is frequently inhibited by poor compliance and complaints. Amblyz™ liquid crystal glasses utilize an intermittent occlusion technique (at 30-second opaque/transparent intervals) and avoid adhesive, potentially improving compliance. This study compares compliance with Amblyz™ glasses versus patching. Methods: Sixteen children (3-8 YR) with untreated, moderate, unilateral amblyopia were enrolled. All subjects wore optimal refractive correction for 12 weeks and were associated with strabismus, anisometropia, or both. Subjects were randomized into two treatment groups: a 4-hour Amblyz™ glasses group, or a 2-hour patching group. Compliance was reported with a calendar log and an Amblyopia Treatment Index (ATI) questionnaire characterizing the experience. Results: At 12 weeks, compliance averaged at 82% in the patch group and 79% in the Amblyz™ group (no statistical difference). No adverse effects were reported. In the Amblyz™ group, some parents reported that their child had trouble seeing outside at night secondary to the tint inherent to the liquid crystal lenses; some parents complained that the glasses were easily subject to damage by their child. The ATI demonstrated a high level of enthusiasm from parents and children with the Amblyz™ glasses, commonly remarking that they were easier to wear and generated fewer complaints. Visual outcome measures are reported in a related abstract. Discussion: These preliminary results are limited by the small sample size and short-term followup. Conclusion: Compliance with Amblyz™ glasses is similar to patching, even when wearing time was doubled in this trial. This promising device provides an alternative amblyopia treatment for children. 91 Electronic Poster 2 Electronic Poster 3 Prevalence of Amblyopia in Children in Bulgaria Stela P Dikova MD Violeta S Chernodrinska MD, PhD Children`s Eye Hospital “Visus” Sofia, Bulgaria Introduction: The purpose of this study was to establish the prevalence of amblyopia in children, aged 4 to 18, in Bulgaria, that presented a complaint or were consulted by ophthalmologist because a parent noticed an abnormality. Methods: A complete ophthalmology exam was performed on 285 children in the period 05.01.2014-05.31.2014 in Children’s Eye Hospital ‘Visus’ in Sofia, Bulgaria. All patients who came in for a prophylactic exam in the period in question were excluded. Amblyopia was defined as reduction of the best-corrected visual acuity for near and far under 40/60 on one or on both eyes. Squint, poor vision, difficulty in school, headache were the main complaints presented. Results: 59 out of 285 children had amblyopia (20,7%). 36 of them had amblyopia resulting from strabismus (61%); 11 - anisometropia (18%); ten - high bilateral refractive errors (16,9%), and two - cataract (3,4%). 43 children presented unilateral amblyopia (73%), 16 - bilateral amblyopia (27%). Discussion: High prevalence of amblyopia (20,7%) shows lack of screening program involving children at an early age, poor compliance of the patient/parents and/or delay in the treatment of the causes for amblyopia, in Bulgaria. A recent study conducted over 1861 ‘healthy’ school-aged children in northwest Bulgaria reports 4,3% prevalence of amblyopia. Conclusion: The lack of screening programs is the main reason for the higher prevalence of amblyopia in Bulgaria compared to North America and other developed countries. Other factors include: insufficient number of pediatric ophthalmologists in the country and the lack of awareness among the parents. References: A.

European Journal of Pediatric Ophthalmology and Strabismus 2014: Jun 25; 1-5 Electronic Poster 4 False Positive Amblyopia Prediction During Fixation Preference Testing of Strabismic Patients (“pseudoamblyopia”) Correlates with Ocular Dominance Arif O. Khan MD; Dora H AlHarkan MD King Khaled Eye Specialist Hospital Riyadh, Saudi Arabia Introduction: Binocular fixation preference testing (BFPT) is a commonly used clinical method to predict Strabismic amblyopia in preverbal children. However, false positives are a concern and can lead to inappropriate patching treatment. We explore potential correlates for this phenomenon. Methods: Prospective cohort study (2013-2014) of consecutive verbal Strabismic patients without incomitance or decreased vision other than strabismic amblyopia. BFPT was graded from 1 (strong preference) to 4 (free alteration), with grade 1 or 2 considered predictive of amblyopia; this was later compared to the presence/absence of true Strabismic amblyopia. Ocular dominance and hand dominance were assessed, and previous patching history was documented. Results: Of 114 enrolled subjects (mean 7.9 years old, range 3.4 to 22.4; 63 males and 51 females), 98 (86%) had esotropia and 16 (14%) had Exotropia (mean primary position horizontal strabismus 27.9 prism diopters [PD], range 8-70 with only one <10). For false positives (39/114, 34.2%), fixating eye correlated with ipsilateral ocular dominance (79.5%, chi square p value <0.0001) but not with hand dominance or recent patching history. Positive predictive value was poor (45.8%, 95% confidence interval [CI] 34.058%) but negative predictive value was high (97.6%, 95% CI 87.4-99.6%). No subgroup (of type or degree of strabismus) differed. Discussion: False positives are common during BFPT of strabismic patients and preferred fixation in such cases correlates with ipsilateral ocular dominance, which is a likely explanation for this phenomenon of “pseudoamblyopia.” Conclusion: FBPT is more useful for predicting the absence rather than the presence of strabismic amblyopia.

The aim of our study was to explore its use amongst UK ophthalmologists. Methods: We designed an electronic questionnaire that was sent to UK paediatric ophthalmologists (members of BIPOSA). Results: There were 46 survey respondents: 42 (91.30%) used atropine penalization always, often or sometimes. Only 1 (2.17%) always used it first line, whilst 22 (47.83%) sometimes used it first-line, most commenting it was often parental choice. The most common reason given for using atropine penalization was non-compliance with patching (88.64%). Reverse amblyopia was reported by 13 respondents (28.26%). Just 16 ophthalmologists (34.78%) felt that in their practice atropine penalisation was as effective as patching. Discussion: Atropine penalization appears to be used most commonly as second-line treatment in UK ophthalmology departments, and usually when there are compliance issues with patching. Comments from respondents indicated that many felt unfamiliar with it so tended to use it less than patching, and when used first-line it was more often parental rather than clinician choice of treatment. Few raised concerns about sideeffects, and of those reporting reverse-amblyopia, all commented that it was one or two cases in their paediatric experience. Conclusion: Whilst clinicians are aware of the results of the PEDIG trials, and few have major concerns that atropine penalization is a safe alternative to patching if carefully monitored, there is still reluctance to use it first-line amongst UK paediatric ophthalmologists. Departmental audits should be encouraged and may increase clinician support for this method of treatment. Binocular dichoptic video content treatment for amblyopia - pilot study Chaim Stolovitch MD Gad Dotan MD Noa Delman MD Daphna Mezad MD Department of Ophthalmology,Tel Aviv Medical Center and Dana Children’s Hospital Tel Aviv University, Tel Aviv, Israel Introduction: Patching and Atropin penalization have been the main treatment for amblyopia overcoming the blocking or suppression of the amblyopic eye by the sound one. In recent years new insights emerged for treatment of amblyopia using binocular stimulation dichoptically. Our objective was to assess a novel device for treatment of Amblyopia, using dynamically altered dichoptic presentation of video contents without patching. Methods: We used a dedicated software that alter dynamically video content presented dichoptically binocularly, using Reviview™ video goggles, in which reduced contrast of the video content is presented to the good eye compared with enhanced contrast video content to the amblyopic eye. Eighteen subjects, age 4-8 years, diagnosed with refractive or strabismic amblyopia, with VA worse than 6/15 (20/50) in the amblyopic eye were enrolled. All the children were reluctant for further patching or using atropine and their compliance was bad. All used the device for 30-60 min daily while watching animated TV shows at home without patching. Visual Acuity and Randot stereoacity were assessed at baseline and after 4,8 and 12 weeks of treatment. Results: 16 patients completed 12 week of treatment.Two of our patients stopped treatment after 4 weeks. At the 4-week visit, visual acuity improved significantly (mean 0.1828 ± 0.1443 logMAR) in the amblyopic eye, (T value=5.4175,P=0.001),at 8 weeks visit (N=16,mean 0.2475 ± 0.1267 logMAR) (Anova= F value=7.373,P=0.0017)and at 12 weeks (N=16,mean 0.2681 ± 0.1645 logMAR) (Anova=F value=6.61211,P=0.0066 from base line Visual Acuity. Discussion: New treatment modalities for amblyopia were introduced in recent years. Mainly by Robert Hess and Elain Birch.They have used Ipad with Tetris and likewise games achieving mean improvement of 0.08±0.01 logMar at 4 weeks with no improvement with further treatment to 8 weeks. Our device and protocol of treatment achieved much better results at 4 weeks of treatment 0.1828 ± 0.1443 logMAR with continuous improvement towards the 12 week visit 0.2681 ± 0.1645 logMAR. Conclusion: The use of a dynamically altered dichoptic presentation of everyday video using Reviview™ video goggles without patching has the potential to be used as treatment for Amblyopia.

A Electronic Poster 6 Electronic Poster 7 Measurement tool for assessing visual function in patients with amblyopia Kathryn P Winkler, MD Sabin Dang, MD Rebecca Schwarzlose, PhD Reecha S Bahl, MD Kresge Eye Institute, Detroit, MI Introduction: Amblyopia is the most common cause of visual impairment in children. In both clinical and research settings, the degree of amblyopia is often measured solely with the assessment of visual acuity. However, it is well known that the loss of visual function is more complex than just loss of acuity. Our group presents a software tool that allows for the quantitative measurement of amblyopia focusing on four factors: stereopsis, contrast sensitivity, acuity, and crowding. Methods: We produced software that presented several stimuli. To assess visual acuity, standard letter stimuli of varying sizes were presented over a 50% gray background, with the subject instructed to identify the letter presented. Contrast sensitivity was determined using gabor patch sinusolidal gratings of various luminance profiles. Crowding was quantified in a two-dimensional fashion with flanking letters presented around a central letter. The flanking stimuli were adjusted in both size and distance from the target stimuli. Lastly, we asked subjects to perform a three-dimensional spatial discrimination task while wearing red-green glasses. All tests were performed in an adaptive manner using the QUEST algorithm to determine a threshold at which patients could accurately identify each stimulus. Results: Using our method, we are able to quantitatively define the visual function of a given subject on several dimensions: acuity, contrast sensitivity, crowding, and stereopsis. Discussion: Clinical studies involving amblyopia have relied on simple visual acuity as an indicator of visual function. Using well characterized methods from visual psychophysics research, we are better able to quantify the visual function of a patient. Conclusion: We believe using this tool in clinical studies can provide a more nuanced assessment of visual function in patients with amblyopia. Electronic Poster 8 Alternate Occlusion for Bilateral Ametropic Amblyopia Di Zou Lucy Stafford Saurabh Jain Mr Royal Free London NHS Foundation Trust The Royal Free Hospital, Pond Street, NW3 2QG Introduction: Bilateral ametropic amblyopia occurs in the presence of high refractive error and is attributed to pattern deprivation. Current treatment advocates full-time spectacle wear whilst the use of alternate occlusion and simple occlusion are supported by anecdotal evidence and are implemented as a rare treatment option in some UK hospitals. This study looks at the effectiveness of alternate occlusion and simple occlusion in comparison to spectacles with respect to bilateral ametropic amblyopia. Methods: The study was a retrospective, case-note review. Twenty-eight case notes of patients with bilateral ametropic amblyopia were reviewed in order to assess improvements in visual acuity. Patients were then divided into spectacles only (A), simple occlusion of the worse eye (B) or alternate eye occlusion (C) groups. Comparisons were then made using spectacles only as the control. Results: Change in monocular visual acuity for A was 0.19 and 0.01 for the right and left eyes respectively; for B was 0.22; and for C was 0.26 and 0.24 for the right and left eyes respectively. Comparison of alternate day or simple occlusion versus spectacles only revealed no statistical significance. Discussion: Alternate day occlusion and simple occlusion do not significantly affect the outcome of monocular visual acuity after one year. Spectacle wear remains the most effective treatment for bilateral ametropic amblyopia. Conclusion: Based on our results, we recommend the cessation of alternate occlusion as a management option for patients with bilateral ametropic amblyopia. 94 Using Anterior Segment Imaging as a Guide for the Surgical Management of Pediatric Corneal Opacities Luxme Hariharan MD, MPH Dilshad Contractor MBS Julia Johnston MPAP Tova Mannis MD Bibiana Jin Reiser MD, MS Children’s Hospital of Los Angeles, USC Eye Institute Los Angeles, CA Electronic Poster 9 Introduction: Pediatric corneal scarring and opacities often present a problem in the visual development of children as the early obstruction of the visual axis can result in irreversible vision loss. The purpose of this study is to identify to role anterior segment OCT can play a role in the surgical decision making of children with partial and full thickness corneal opacities that are possible to transplant. Methods: This is an ongoing IRB-approved prospective observational study of 41 patients at the Children’s Hospital of Los Angeles that underwent anterior segment imaging for possible corneal surgery. Inclusion criteria included children age 1 month to 18 years old with corneal opacities affecting the visual axis. Surgical options included: 1) Laser-assisted anterior keratoplasty (LALAK), 2) Penetrating keratoplasty (PKP) or 3) No surgery. Using OCT findings and pacchymetry we determined whether PKP vs. DALK vs. LALAK was best for each patient. Results: Based on the anterior segment imaging a clinical exam, 4 were candidates for anterior lamellar keratoplasty, 9 were for PKP, and 26 were not surgical candidates. Discussion: The majority of children in our study had corneal opacities that were full thickness on anterior segment OCT imaging and therefore needed surgical treatment via PKP rather than DALK or LALAK. These deep opacities may be further examined with dynamic Ultrasound Biomicroscopy (UBM) rather than anterior segment OCT and clinical exam alone, for greater detail. Conclusion: Anterior segment OCT imaging can be a useful tool in guiding a surgical plan for pediatric corneal transplants as opposed to clinical exam alone for patients with partial and full-thickness corneal opacities.

Radhakrishnan, et al, “ Optical Effect on blink rate during videogame related activities and reading in school-aged children Catherine O Jordan MD and David L Rogers MD Nationwide Children’s Hospital, Columbus, OH Introduction: This study compared blink rate per minute (B/m) during an interview, reading a book and playing a videogame. Methods: Children aged 5 to 17 were recruited for a pilot study. Participants were individually videotaped for five minutes during each of these activities: being interviewed for dry eye symptoms, reading a book and playing a handheld videogame. The videos were reviewed and B/m was recorded. A two-tailed matched pairs t-test was used for statistical analysis. Results: 20 healthy subjects were recruited. Mean blink rates were: interview 11.91 B/m, reading 5.97 B/m and videogame 6.92 B/min. The mean blink rate during the interview was statistically higher compared to reading (p <0.05) and videogame activities (p<0.05). Subjects found to have more dry eye symptoms (n=10) had lower mean blink rates during reading (3.79 B/m) and videogame activities (3.97 B/m) than subjects with low to no symptoms (n=10) during the reading (8.15 B/m) and videogame (9.86 B/m) activities. This trend was not statistically significant. Discussion: We showed a statistically significant decrease in blink rate during reading and videogame use compared to an interview conversation. This decrease may be due to increased visual demand of the near tasks. Although it wasn’t statistically significant, decreased blink rates may be related to dry eye symptoms in children. Conclusion: In children, blink rate decreases during activities such as reading and playing videogames compared to conversation. This may play a role in dry eye symptoms that occur during these activities. References: 1. Lavezzo MM, Schellini SA, Padavani CR, Hirai FE. Eye blink in newborn and preschool-aged children.

Categorization, associated conditions, and prognosis are controversial. Methods: All children with excessive blinking were reviewed, excluding those with known uveitis, glaucoma, or obvious eyelid abnormalities. Parents were telephoned for follow-up. Results: A total of 74 children (54 boys), aged 1 to 10 years (mean 4.7), had excessive blinking for 3 days to 1.5 years (mean 2.5 months). Parents were contacted in 55% of cases. In 26, parents could not identify a cause. In 2, Tourette syndrome was diagnosed, 1 following presentation. In 2, dexmethylphenidate (a stimulant used for ADHD) was suspected to be the cause. There was complete resolution in 29, some improvement in 8, and no improvement in 4 cases. No new ophthalmologic diagnoses were uncovered. Discussion: All children with excessive blinking should undergo ophthalmologic examination. Families should be encouraged to follow-up as needed for redness, light sensitivity, or other eye symptoms. If blinking persists, further evaluations can be coordinated with the pediatrician. Conclusion: Episodes of excessive blinking rarely indicate neurologic disorders and frequently resolve spontaneously. Electronic Poster 12 Peters anomaly phenotypic spectrum - from mild to severe disease Kamiar Mireskandari Uri Elbaz Hermina Strungaru Asim Ali Department of Ophthalmology and Vision Sciences, Hospital for Sick Children University of Toronto Toronto, Ontario, Canada Introduction: The phenotypic diversity of Peters anomaly leads to differences in management and outcomes for this condition. With improved imaging techniques we can further understand the wide spectrum of Peters anomaly and potentially modify the grading scale for disease severity and provide a flowchart that simplifies the decision-making process. Methods: The charts and images of patients with Peters anomaly between January 2000 and December 2013 were reviewed retrospectively. Anterior segment imaging including RetCam or slit lamp photographs, optical coherence tomography and ultrasound biomicroscopy images were utilized and served to assess anatomical features and abnormalities in relation to visual outcome. Results: Eighty-two eyes of 56 patients were included in the study. Seventy-one eyes (86.6 %) had a centrally located opacity and 60 eyes (73.2%) had a dense opacity obscuring iris details. Iridocorneal adhesions (90.2%), Corneal vascularization (37.8%), posterior corneal thinning (35.4%), keratolenticular adhesions (21.9%), cataract (26.8%) and aphakia (1.2%) were features associated with Peters anomaly. Also 20% of patients with moderate Peters had very flat keratometry (36-38D) and high hyperopia. Natural history of Peters involves mild resolution of corneal opacity; hence optical iridectomy and pupil dilation were successfully utilized in third patients with a mean final corrected distance visual acuity (CDVA) of 0.4 logMAR. In contrast severe opacity required corneal transplantation with a mean final CDVA of 1.1 logMAR. Discussion: Our study further describes phenotypic features in relation to management and outcomes of Peters anomaly and will be compared to the literature. Conclusion: Peters anomaly presents with variable phenotype requiring tailored management based on disease severity. 96 Lamellar Keratoplasty for Excision of Limbal Dermoids Oriel Spierer MD Richard K Forster MD Bascom Palmer Eye Institute, University of Miami Miller School of Medicine Miami, Florida, USA Electronic Poster 13 Introduction: The purpose of this study is to assess the surgical outcomes of visual acuity, refraction and cosmetic appearance in patients that underwent limbal dermoid excision with lamellar keratoplasty. Methods: The charts of 8 consecutive patients who underwent limbal dermoid excision with lamellar corneoscleral graft transplantation, by one surgeon, were retrospectively reviewed. Comparison of visual acuity, spherical equivalent and astigmatism before and after the surgery was done. Vector analysis was used to evaluate the change in astigmatism after the surgery. Results: Mean age of patients at day of surgery was 13.0 years old (62.5% female). Mean dermoid size was 7.75 mm. Indications for surgery were cosmetic appearance, high astigmatism and ocular irritation. Mean visual acuity (in LogMAR units) before and after the surgery was 1.8 and 1.7, respectively (p=0.79). Spherical equivalent was 1.3 D before the surgery and 0.7 D after the surgery (p=0.52). The mean astigmatism before and after the surgery was 2.4 D and 1.5 D, respectively (p=0.37). Vector analysis revealed mild change in astigmatism with mean ‘d’ of 3.2 (0.56-6.89). None of the patients had graft complications and patients had good cosmetic outcome. Discussion: Surgical techniques for dermoid excision include simple excision, superficial keratectomy, penetrating keratoplasty and lamellar keratoplasty. Indications for excision include poor appearance and astigmatism. However, there is not enough support in the literature that limbal dermoid excision reduces astigmatism. Conclusion: Lamellar keratoplasty for limbal dermoid is safe and offers good appearance and tectonic stability. Significant improvement in the amount of astigmatism is not expected following surgery.

Endophthalmitis after cataract surgery in children SUMITA AGARKAR MD ROSHNI DESAI MD MEDICAL RESEARCH FOUNDATION , SANKARA NETHRALAYA 18 , COLLEGE ROAD , NUNGAMBAKKAM, CHENNAI , TAMILNADU, INDIA Introduction: Endophthalmitis following cataract surgery is a rare and devastating complication. There is a paucity of litreture regarding postoperative endophthalmitis following cataract surgery in children . We present a retrospective case series of 9 cases of endophthalmitis following elective cataract surgery in children Methods: Retrospective review of charts of all children with a diagnosis postoperative endophthalmitis following cataract surgery at a tertiary care hospital in India between year 2000 to 2012, by a single surgeon , was done . All children who had a diagnosis of traumatic cataract were excluded. Diagnosis of endophthalmitis was based on clinical signs and symptoms as well as diagnotic modalities like aqueous and vitreous culture , Gram staining etc. Special note was made if patient had any symptoms suggestive of nasolacrimal duct obstruction prior to the cataract surgery Results: A total of 9 patients out of 1446 patients aged between 5 months to 14 years (mean - 5.9 years )developed symptoms and signs suggestive of post operative inflammation / infection following uneventful elective cataract surgery. None of the patients in this series had nasolacrimal duct obstruction.All of them , barring one, reported within 72 hours after an uneventful cataract surgery. All patients recieved intravitreal antibiotics and steroid. Vitrectomy was required in 5 out of 9 cases. 6 patients tested positive for eubacterial genome on PCR .Only 4 patients had positive vitreous culture. Organisms isolated on culture were Staphylococcus , Acinetobacter and Pseudomonas species. The mean follow up was 5.10 years (1.17 to 13 years). At the last follow up, 7 out of 9 eyes had visual acuity better than 6/24; one eye was amblyopic.Only one eye had nil perception of light and was prepthysical. Three patients required additional surgery for retinal detachment Discussion: There are few reports available on endophthalmitis following cataract surgery in children .Nasolacrimal duct block has been cited as a risk factor however none of children in this series , had any clinical evidence of nasolacrimal duct obstruction.Visual outcome has been reported to be very poor. Wheeler et al have reported 65%of patients devloping nil perception of light in contrast to our series. Good visual outcome in our series could be attributed to either low virulence of organisms or early vitrectomy Conclusion: Post operative endophthalmitis is a serious vision threatening condition .Clinicians should maintain a high index of suspicion in the event of any unexplained inflammation in immediate post operative period that is first 72 hours . Aggressive intervention in form of intravitreal injections and early vitrectomy may help in achieving good anatomic and visual outcomes References: 1.Wheeler DT , StagerDR , Weakley DR jr.

Methods: Review of surgical logs(1993-2014) for unilateral cataract surgery in the first year of life and minimum 1 year follow-up. Children with identifiable syndromes associated with nystagmus and posterior segment abnormalities were excluded. Variables studied included age at surgery, amount of prescribed patching and compliance, additional surgical interventions, visual acuity measures and strabismus. Comparison of variables between the groups with and without nystagmus was made. Results: 12/101(11%) children with nystagmus were identified; 6 were excluded (Down syndrome, metabolic disorder, encephalopathy). Of the 95 remaining patients, 81 had contact lens correction of aphakia within one week of surgery, 14 had primary IOL implantation. Median age at surgery was lower for those with nystagmus 40 vs. 60 days (mean, 96 vs. 107 days). No difference in patching recommendations or compliance was associated with nystagmus except for one patient who developed reverse amblyopia and nystagmus after compliance with almost full time patching. At age one year, mean logMar visual acuity in the phakic eye was 0.64 in the nystagmus group compared to 0.71 in the control group. Final recognition acuity of the operated eye was better than 20/200 in 3/12 children with nystagmus and 34/89 without nystagmus. Anomalous head posture was observed in 8 children. Conclusion: Bilateral manifest nystagmus is seen in a significant proportion of children with monocular congenital cataract; no overall associations were noted. Over-rigorous patching can lead to reverse amblyopia and nystagmus caused by early bilateral deprivation. Electronic Poster 16 Pentacam and OCT Imaging Techniques in Pseudophakic Eyes of Children Catherine Gasper BS, M Edward Wilson MD, Rupal H. Trivedi MD Storm Eye Institute, Medical University of SC Charleston, SC, USA Introduction: We sought to evaluate Pentacam and OCT imaging techniques in pseudophakic eyes of children. Our objective is twofold: to compare data from 1) randomly selected pseudophakic eyes of bilateral cases to that of monocular pseudophakic eyes; and 2) pseudophakic eyes of monocular cases to that of the fellow unoperated eyes. Methods: Prospective ongoing study evaluating Pentacam and OCT. We excluded patients with traumatic cataract. Data were statistically analyzed using independent sample and paired T-test. Results: Of the twenty-one patients photographed, data from seven patients with monocular cataract and ten patients with bilateral cataracts were further analyzed. The mean age at time of cataract surgery was 4 years (SD=5). Twelve patients received primary IOL and five received secondary IOL. Corneal thickness (central, nasal, temporal, superior, inferior, and thinnest), anterior chamber depth, and central macular thickness was not significantly different between patients operated for bilateral cataract and those with monocular cataract (P>0.05). However, corneal thickness (nasal, interior), anterior chamber depth and central macular thickness was significantly different in patients operated for monocular cataract as compare to the fellow unoperated eyes (P = 0.001, 0.014, <0.001 and 0.003 respectively). Corneal thickness in other areas did not reach statistical difference (central, temporal, superior, thinnest). Discussion: This is an early, exploratory study using Pentacam and OCT adult imaging techniques for pseudophakic eyes of children. These non-contact imaging modalities will likely see increased use in pediatric patients. Enrollment in our study is ongoing. Conclusion: Pseudophakic eyes of children operated for bilateral cataract and monocular cataract appears to have similar results on Pentacam and OCT, while eyes operated for monocular cataract were noted to have differences as compared to the fellow unoperated eyes. 98 Preferred Practice Patterns for Pediatric Cataract Surgery and Post-Operative Management Gennifer J Greebel1 Majida A Gaffar2 1 Electronic Poster 17 Ophthalmology, Edward S. Harkness Eye Institute, Columbia Presbyterian, New York, NY 2 Ophthalmology, North Shore-Long Island Jewish Medical Center, Great Neck, NY Introduction: To evaluate the practice patterns of pediatric cataract surgeons, summarize new surgical techniques, and establish appropriate guidelines in this evolving field. Methods: Invitations to participate in an internet-based survey were sent to 1330 physicians of The American Academy of Pediatric Ophthalmology and Strabismus (AAPOS). A 35-question survey evaluated the surgeon’s experience, operative techniques, and long-term management choices. Included physicians completed a pediatric ophthalmology fellowship, and perform cataract surgery domestically. Results: Seventy-six physicians of the 142 responses were included. The respondents were subdivided into Group A, surgeons who perform < 20 surgeries yearly, and Group B, surgeons who perform greater than 20 surgeries yearly. There were 60 surgeons in Group A and 16 surgeons in Group B. A Fisher’s exact test was performed for all questions on the survey, comparing Groups A and B. Although there appeared to be many questions where practice patterns differered between the two groups, the only question with statistically significant results addressed the appropriate age in which to place a primary lens implant. Group A mostly implants primary lenses between years 1-2, whereas Group B tends to place lenses earlier between 8 months and 1 year (p-value < 0.032). Discussion: Newly developed medications, innovative surgical techniques, improved treatment of inflammatory conditions, and decreased mortality of prematurity, create more challenges and management options for pediatric cataracts. While most surgeons adopted new ways to treat their patients, some therapies are mostly utilized by more experienced surgeons. A variety of surgical and post-operative situations exist, however, that lack consensus regardless of expertise. Conclusion: The diversity of therapy for pediatric cataracts reveals the need for further investigation and continued education, in order to determine the best management protocols.

Traumatic Cataract In Children: A Long Term Follow-Up- A Retrospective Observational Review ASSAF HILELY MD HANA LEIBA MD REUT PARNESS-YOSSIFON MD Department of Ophthalmology, Kaplan Medical Center Rehovot, Israel Introduction: To review long term results of operated unilateral traumatic cataract, due to either blunt or penetrating traumas, in children. Methods: A retrospective observational case series. Files of all children under the age of 18 years who had unilateral traumatic cataract between the years 1983-2009 were reviewed. Exclusion criteria included trauma to posterior segment and follow up of less than 5 year. Main outcome measures were final visual acuity and any complications. Results: Of 18 children included, 83% were males. Mean follow-up time was 12.5 years (5-30) Median age at injury was 7.5 years (range 2.6-17). Trauma was penetrating in 11 patients (61%) and blunt in 7 (39%). 16 patients (89%) had cataract already on admission (10 had penetrating trauma and 6 blunt trauma) and 14 of them needed operation. In 2 patients the cataract developed along the follow up (1 blunt and 1 penetrating) and they were operated. Following lensectomy, an intraocular lens implantation was performed in 14 (87.5%) of the patients, either in the first operation (43%) or as a secondary procedure (57%). Mean final visual acuity (VA) was 20/40 (Light Perception-20/20) in the pseudophakic group and 20/2000 (Hand Movement-Counting Fingers) in the aphakic group.In the pseudophakic group, intraocular lens dislocation was diagnosed in 36% of the patients. No additional interventions for lens reposition were performed. Final mean VA was 20/63 in the dislocated group and 20/32 in the non dislocated group. Four (29%) of the pseudophakic patients (3 with penetrating and 1 with non penetrating trauma) developed glaucoma compared to both (100%) of the aphakic group (all with penetrating trauma). Posterior capsular opacity developed in 11 (79%) of the patients, Posterior capsule opening was performed in 9 of them (7 YAG-laser and 2 surgical). Discussion: Traumatic cataract was found to be more common among males. Penetrating trauma was more frequent. Pseudophakic patients had better visual acuity and less glaucoma. Final VA was good even with lens dislocation, better than aphakia albeit worse than without dislocation. Conclusion: Children with traumatic cataract without initial damage to the posterior segment tend to have favorable long term results. Glaucoma developed in all the aphakic patiens, probably due to a severe initial injury. 99 Electronic Poster 18 Electronic Poster 19 Visual Acuity and Refractive Outcome in Pediatric IOL Implantation with Initial Low vs High Hyperopia Dayane C Issaho Serena Wang Monica Bratton David Weakley University of Texas Southwestern Dallas Introduction: Purpose: To compare the impact of initial post-operative refraction on the visual acuity and refractive outcome in children after primary intraocular lens (IOL) implantation following cataract extraction. Methods: The records of all patients who underwent non-traumatic cataract extraction with primary IOL implantation under 7 years of age were reviewed over a 12-year period. Eyes were divided into 2 groups: (1) initial postoperative refraction < +3.00 D spherical equivalent (SE) and (2) ≥ +3.00 D SE; and also analyzed according to the age at surgery: < 2, 2 to < 4 and, 4 to ≤ 7 years old. Results: Sixty-four patients (88 eyes) were included; 55 eyes in the initial low hyperopia group and 33 eyes in the high hyperopia group. The mean acuity at the most recent visit was 0.5 logMar (SD 0.55) in group 1 (mean follow-up 65 months) and 0.58 logMar (SD 0.45) in group 2 (mean follow-up 49 months) (p = 0.75). Visual acuity outcome was not affected by age at surgery. Mean SE at the last visit was -1.55 D in group 1 vs -0.21 D in group 2 (p = 0.62). The age 0-2 subgroup had a greater myopic tendency when initially < +3.00 D (-5.08 D SE vs -2.61 D SE, p=0.71). Discussion: Conclusion: More modest initial refractive undercorrection (<+3.00 D) after primary IOL implantation does not improve visual outcome or later refractive status, especially in the younger children who have a greater myopic shift. Electronic Poster 20 Structural Changes of the Anterior Chamber Following Cataract Surgery During Infancy Matthew Nguyen MD Scott Lambert MD Allen Beck MD Marla Shainberg CO Emory Eye Center, Atlanta, GA Introduction: Glaucoma occurs in up to 30% of children after cataract surgery during infancy(1,2), possibly because of structural changes of the anterior segment causing the trabecular meshwork to ‘collapse(3).’ Methods: After obtaining informed consent, the Heidelberg SPECTRALIS was used to measure the angle opening distance (AOD) and trabecular iris angle (TIA) and the IOLMaster to measure the anterior chamber depth (ACD), corneal diameter and axial length (AL) for 7 children, ages 6 to 12 years old, who underwent unilateral cataract extraction with or without primary intraocular lens placement when <7 months of age. An ocular examination was also performed. Results: Unilateral cataract surgery was performed at a mean age of 2.2 (range, 0.9 to 4.2) months. Five treated eyes were aphakic and 2 were pseudophakic. Patients were examined at a mean age of 9.2 (range, 6.6 to 12.5) years. No eyes had glaucoma. The mean IOP was 17 mmHg in treated eyes and 16 mmHg in fellow eyes. Mean ACD was greater in fellow (3.48 mm) than treated eyes (2.93 mm). ACD was deeper in pseudophakic eyes (IOL, 3.10 mm; aphakic, 2.85 mm) and AOD (IOL, 843 µm; aphakic, 767 µm) and TIA (IOL, 42°; aphakic, 37°) were greater in pseudophakic eyes. Discussion: Pseudophakic eyes had a shallower ACD than fellow eyes, but were deeper than aphakic eyes. Conclusion: Cataract surgery during infancy causes structural changes in the anterior chamber. Primary implantation of an IOL was associated with a deeper anterior chamber and greater TIA than eyes without IOL implantation. References: 1. Lambert SR, Purohit A, Superak HM, Lynn MJ, Beck AD.

Methods: Retrospective chart review of pseudophakic children operated age 2-6 years with minimum followup of 3 years. The refractive error was recorded at 1-2 months after surgery and then yearly. Mean myopic shift was determined and refractive change per year was calculated. Results: 42 eyes of 27 children met the inclusion criteria. Mean age at the time of surgery: 3.9 years, mean followup: 7.5 years (range, 3-14). Patients operated between 2-3 years (n=12) had slightly greater mean myopic shift of -3.2 D compared to -2.6 D in 3-4 years (n=14) and -2.7 D in 4-6 years (n=16). Myopic shift per year was not significantly different in these age groups (0.5 D/year, p=0.7, ANOVA). Myopic shift was somewhat higher in unilateral than bilateral pseudophakia (-3.0 vs. -2.8 D; n=12 vs. 30; p=0.7, unpaired t test). Discussion: While most axial growth and myopic shift occurs before 2 years, a variable amount of refractive change can occur in the pre-school population, so most surgeons aim for post-operative emmetropia around 6 years of age. Conclusion: There is a myopic shift of 0.5 D/year in children operated between age 2-6 years. Myopic shift is somewhat greater in younger children and unilateral pseudophakia. References: 1.

Methods: This is a retrospective, non-randomized, single center, IRB approved study in which the charts of all pediatric patients with bilateral cataracts between 2004 and 2013 were reviewed. Children with CNS disease or other ocular abnormalities were excluded. A mixed effects ANOVA or hierarchical logistic regression was performed for the variables analyzed. Results: 29 subjects were included, 16 with nuclear cataracts and 13 with lamellar cataracts. The median age at surgery for subjects with nuclear cataracts was 3 months (range: 3 weeks to 30.5 months) and with lamellar cataracts was 58 months (range: 3.5-91 months). In the nuclear cataract group, there was no statistically significant relationship between age at surgery and VO (p=0.3951), or age at surgery and post-operative nystagmus (p=0.8710). There was also no evidence that pre-operative nystagmus affected the VO in that group (p=0.2836). In the lamellar group, all patients had their surgery after our 10-weeks cut off. In both cataract morphology groups, post-op nystagmus was associated with poorer VO (p=0.0617 in the nuclear group, p=0.0038 in the lamellar group). In contrast, irrespective of the type of cataract, strabismus was not significantly associated with a worse VO (p= 0.7195). Discussion: Our results are in agreement with those from VanderVeen et al. who recently reported that pre-operative nystagmus did not portend a poor VO. Conclusion: Age at surgery did not have a significant difference on VO in subjects with nuclear cataracts. The presence of pre-operative nystagmus did not predict poor VO, but post-operative nystagmus was associated with worse VO. References: 1. Young PM, Heidary G, VanderVeen DK.

Methods: Study population: Infants operated by one surgeon for monocular cataract before seven months of age. Globe axial length was measured by immersion ultrasound at surgery and 5 or more years later. Rate of AL growth was calculated as (postoperative AL minus preoperative AL)/preoperative AL x 100. Results: We identified 29 children fulfilling the inclusion criteria. Average age at cataract surgery was 2.6 ±2.1 months, age at last follow-up was 7.7±2.7 years and duration of follow-up was 7.5±2.6 years. 15 eyes received a primary IOL while 14 eyes received a secondary IOL. Preoperatively, AL was significantly different between operative and fellow eye (18.1mm vs 18.8mm, P <0.001), however, at final follow-up it was not (22.4mm vs 22.8mm, P =0.187). AL growth of operative eye and fellow eye was not significantly different (4.2mm vs 4.0mm, P=0.451). Similarly, rate of growth of operative eye and fellow eye was also not significantly different (23.7 % vs 21.5%, P = 0.211). Discussion: We report long-term axial growth in eyes operated for monocular cataract. These eyes have shorter axial length at the time of surgery as compared to that of fellow eye without cataract. Monocular pseudophakic eyes have similar axial growth to that of fellow non-operated eyes. Conclusion: Eyes operated for monocular cataract with primary or secondary IOL implantation have similar axial growth to that of fellow non-operated eyes despite having shorter axial length at the time of surgery. Electronic Poster 24 Associated Systemic and Ocular Disorders in Patients with Congenital Unilateral Cataracts - The IATS Experience Elias I Traboulsi MD, MEd Deborah Vanderveen MD David Morrison MD Carolyn D Drews-Botsch MD Michael Lynn Scott R Lambert MD Cole Eye Institute, Cleveland Clinic Cleveland, OH Introduction: Few reports provide prospectively collected information about ocular and systemic disease in patients with a unilateral congenital cataract. Five year data collection for children enrolled in the IATS has provided an opportunity to explore these associations. Methods: Infants < 7 months of age with a visually significant unilateral cataract were eligible for IATS screening. Data pertaining to the exclusion of patients at screening, and data collected on standardized study forms used at any time for documentation of ocular or systemic disorders were reviewed. Results: 227 infants were referred for possible enrollment. Of those excluded, 3 were premature (<36 weeks), 28 had significant ocular disease (usually PFV or corneal diameter <9mm), and 4 had systemic disorders. 26 were excluded at the time of the 1st EUA, most often because of PFV or variants thereof. During the follow up period for the 114 enrolled patients, the following disorders were diagnosed: Stickler syndrome (1), mitochondrial disease (1), autism (1), and presumed congenital rubella syndrome (1). No patient developed a cataract in the fellow eye. Discussion: While patients with unilateral cataracts may have significant associated abnormalities in the affected eye, the prevalence of associated significant systemic disease is quite low. Conclusion: Some conditions (e.g. Down syndrome) are diagnosed at birth or very early in life, but others may become apparent long after cataract removal. It is extremely unlikely that patients with a unilateral congenital cataract develop a cataract in the other eye. PFV and its variants are the most common associated ocular findings. 102 Long-term Outcomes of Anterior Chamber Intraocular Lens Placement in a Pediatric Cohort Reid P Turner MD Leah Owen PhD, MD Jennifer Davidson MD Rupal Trivedi MD M. Edward Wilson MD Storm Eye Institute - Medical University of South Carolina Charleston, South Carolina Electronic Poster 25 Introduction: The use of intraocular lenses (IOL) in the pediatric population is an evolving paradigm. A posterior chamber location remains the preferable lens position; however, in cases without sufficient capsular support, use of alternate placement, including anterior chamber IOL (ACIOL), is necessary. We report long-term outcomes of ACIOL placement in a pediatric cohort at one institution. Methods: We report a retrospective analysis of 20 pediatric patients ranging in age from 2-23 years, representing 33 eyes, with ACIOL placement at the Storm Eye Institute from 1992-2013. Primary outcome measures included best corrected visual acuity (BCVA), ocular complications, and need for additional procedures. Patient outcomes were stratified by patient age at time of surgery, lens type, axial length, and corneal diameter. Results: Average age at ACIOL implantation was 11.41 years and average follow-up was 46.1 months. The L122uv, U85JS, U85JS, UV65A MTA3UO model lenses were used in this cohort; pre-operative and post-operative BCVA was not significantly different for these groups. Post-operative BCVA for all eyes ranged from 20/20-20/80. The BCVA for all patients improved after receiving an ACIOL (p=0.025). Patients in our cohort demonstrated a 6 % rate of glaucoma, 6% rate of macular edema and 3% rate of vitreous hemorrhage. Ten of 33 eyes required additional procedures, 6 of which included ACIOL explantation, 4 included repositioning. The primary indication for additional procedures was lens rotation causing pupil distortion and photophobia. Age at implantation was an average of 9.6 years for the group requiring explantation versus 12.2 years for those not requiring explantation (p=0.08). Average corneal diameter, lens type and axial length were not significantly different for those requiring explantation compared who did not. BCVA did not significantly worsen after additional procedures (p=0.41). Discussion: Long-term outcomes for ACIOL placement in the pediatric population are unclear. Overall, our data show a good postoperative visual result after ACIOL placement. However, we demonstrate a 30% rate of re-operation among pediatric patients receiving ACIOLs. Our data show a trend for younger age at time of ACIOL implantation as a risk factor for needing subsequent repositioning or explantation surgery. Conclusion: ACIOL use in the younger pediatric population may be associated with an increased rate of explantation. Further work is needed to better characterize risk and identify patient risk factors. Benchmarks for outcome indicators in pediatric cataract surgery Deborah VanderVeen, MD; Bharti Nihalani-Gangwani,MD;Olumuyiwa Adebona,MBChB,MPH; Will Dean,MD Boston Children’s Hospital Boston, MA Introduction: Benchmark studies have been published for cataract surgery outcomes in adult populations. The purpose of this study is to evaluate outcome indicators to ascertain quality in pediatric cataract surgery. Methods: Chart review of cataract surgeries performed for patients <18 years of age from 2006-2013 at a single center by multiple surgeons. Patients with ocular co-morbidities were excluded. Outcome measures were: 1) Final best corrected Snellen visual acuity (BCVA) for bilateral cataract patients 2) Prediction error (PE): Expected refractionActual refraction, assessed 1 month postoperatively, irrespective of age or laterality. Results: 1) BCVA was 20/40 or better in 94% (n=88 eyes, mean age: 8.4 + 4.6 years). Remaining 5 eyes with BCVA < 20/40 had amblyopia. 2) PE was within + 0.5 D in 45.0%, +1.0 D in 68.2% and ± 2.0 D in 95.4% (n=172 eyes). Mean absolute PE was 0.9 + 0.7 in eyes with AL < 22 mm (n=79) and 0.7 + 0.5 in eyes with AL > 22 mm (n=93) (p=0.06, unpaired t test). Discussion: This is the first pediatric study that provides benchmark data for visual acuity and refractive error in pediatric eyes. Conclusion: In children, cataract surgery should result in good vision in > 90% of uncomplicated cases; amblyopia is the most frequent cause of VA< 20/40. PE is somewhat greater than benchmarks in adult population studies. References: 1.

The incidence of glaucomatous progression in children is unknown. A retrospective chart review was performed to gauge management trends of pediatric glaucoma suspects and ocular hypertension. Methods: Records were identified using ICD-9 codes for glaucoma suspect and ocular hypertension. Patients older than 10-years of age at the time of search, with prior ophthalmic surgery, diagnosed with glaucoma on initial visit and followed less than two months were excluded. Glaucoma was declared when the patient met the World Glaucoma Association Consensus [1] diagnostic criteria based on their most recent visit. Results: 73 records were included for analysis. Nine patients (12.3%) were diagnosed with glaucoma after a follow up of 12.0 +/- 12.0 months (mean +/- SD), all of whom presented with ocular hypertension. Glaucoma and ocular hypertension patients did not differ significantly in age, average IOP, maximum IOP, corneal diameter, central corneal thickness, cup/disc ratio, RNFL thickness, or axial length. 36.9% of OHTN received IOP-lowering therapy. The treated group had insignificant trend toward having higher maximum IOP (31.6 +/- 13.0 vs 26.3 +/- 5.7 mmHg, P = 0.09), and a significantly higher central corneal thickness (655.1 +/- 97.6 vs 533.5 +/- 54.2 microns, P = 0.0081). Discussion: No glaucoma suspect patient progressed to meet glaucoma diagnostic criteria without presenting with ocular hypertension. Initial biometric findings cannot predict eventual glaucoma progression. Conclusion: Pediatric ocular hypertension patients need to be monitored closely for the development of glaucoma.

Electronic Poster 28 Canaloplasty in Juvenile Glaucoma--A Case Report Susan H Senft MD Susie Y Wong MD Kavita Surti MD Island Eye Care, Inc. Kailua-Kona, HI USA Introduction: Juvenile glaucoma notoriously is challenging to control and surgical approaches have been limited to aqueous shunts with variable success rates. This case report proposes an alternative approach utilizing canaloplasty. Methods: A retrospective review of a male juvenile glaucoma patient age 13 was conducted. The patient was intolerant of maximal medical therapy. Pre-operative baseline testing included visual acuity, visual fields, OCT, Cirrus anterior segment imaging, gonioscopy and fundus photography. He underwent bilateral sequential canaloplasty with retentive stent and has been followed over 22 months. Results: Intraocular pressures on presentation were 28 OD and 50 OS with cupping of 0.7 and 0.9 respectively. Best-corrected visual acuity pre-op was 20/20 and visual fields documented superior and inferior Bjerrum scotomas OD and profound constriction with inferior nasal loss OS. Post-operative pressures maintained IOP of 14 OU on no medication. Visual fields have normalized OD and improved OS, cupping has changed to 0.5 OD and 0.7 OS. Visual acuity has improved to 20/15 OU Anterior segment imaging documented expansion of the Canal of Schlemm from its collapsed state pre-op. Discussion: Problems with older techniques have high rates of failure in juvenile glaucoma. Canaloplasty is minimally-invasive, maximally-effective and appears to work through alterations in the Canal of Schlemm. This report documents improvement/control of the disease with reversal of damage. Conclusion: Canaloplasty appears to present a viable option for juvenile glaucoma and should be included in the treatment paradigm in this difficult and blinding disease. References: 1. Lewis, R.

We examined the utility and feasibility of routine IOP testing with the iCare Rebound Tonometer (IRT) in a pediatric ophthalmology clinic. Methods: All pediatric patients over several clinic days had IOP measurement performed on them using IRT, excluding post-operative and retinopathy of prematurity screening examination patients. Several variables were recorded, including IOP with reliability, length of time taken to measure, and patient comfort level. Results: Our population consisted of a total of 97 patients with mean age of 8.5 years (0.75-18). Mean time taken was 83 seconds (30-254), and mean comfort level was 0.7/10 on the Wong-Baker scale. Success rate at obtaining a reliable IOP was 57%. Mean reliable IOP measured was 16.3±3.7 mmHg (range 8-29), with 6% of the reliable IOP measurements >21 mmHg. Discussion: Our data indicate that IRT is a well-tolerated and relatively quick method to test IOP in children, and can be performed reliably in the majority of pediatric patients. However, the success rate of 57% and documented ocular hypertension in 6% with no suspicion of glaucoma other than the pressure, may not justify routine testing. Conclusion: Routine IOP testing in a pediatric clinic using IRT is easy, quick, and comfortable to the patient, but success rates are less than optimal. IRT is a very useful device for recording IOP in children when other methods are not possible, but it may be best utilized on an as needed basis. References: 1. Lundvall A, Svedberg H, Chen E.

Survey of health- and vision-related quality of life and functional vision in children and young people with childhood glaucoma and cataract Vijay K Tailor Msc Annegret Dahlmann-Noor Dr Gill G Adams Dr Maria Papadopoulos Dr NIHR Biomedical Research Centre at Moorfields Eye Hospital and UCL Institute of Ophthalmology, London Introduction: Impaired vision, repeated surgical interventions, topical eye medications and frequent hospital appointments affect daily life of children with childhood glaucoma, cataract, aphakia and pseudophakia and their families. We aim to explore the health- and vision-related quality of life (QoL) and functional vision (FV) of these children and families. Methods: Recruitment is ongoing: 180 children aged 2-16 years with unilateral or bilateral congenital or secondary glaucoma; cataract, aphakia or pseudophakia and their parents/carers. Parents complete PedsQL™ family report and PedsQL™ about their child; children complete an age-appropriate PedsQL™, Cardiff Visual Ability Questionnaire for Children (CVAQC) and Impact of Vision Impairment for Children (IVI-C). Results: Preliminary results: Parents report that their child’s eye condition has a significant impact on their child’s QoL, as reflected in a total PedsQL™ parental report score of 69 (19) (healthy peers normal QoL – score: 100). Children’s self-report scores are higher than parental reports (all ages: 78 (15)), indicating that children may be less aware or concerned than their parents. Scores increase with children’s age (5-7 years: 65 (21), 8-12 years: 79 (14), 13-16 years: 83 (14)). Parents report they are affected by their child’s condition (41 (38)). Discussion: FV ability measured by CVAQC is reduced ((mean)-1.65 log units (SD 1.038), (-3.00 = normal sight; +2.80 severe visual disability) and related to best-corrected visual acuity in the better eye. Conclusion: Childhood cataract and glaucoma, particularly if resulting in low vision, can affect all dimensions of Qol, i.e. physical, emotional, social, physical and educational. Parents’ QoL can be affected by the child’s condition. 105 Electronic Poster 30 Electronic Poster 31 Accommodation in Children with Cerebral Palsy Claudia Avilés MD Juan Homar Páez MD María Teresa Rodríguez CO Tec Salud Batallon San Patricio 112 Colonia Real de San Agustin, San Pedro Garza García, Nuevo León 66278 Introduction: The purpose of this study is to compare the accommodative response of children with cerebral palsy (CP) to that of a group of healthy children. Clinical evaluation of accommodation is an essential part of assessing visual dysfunction. Having an accommodation deficiency is known to hinder learning abilities and development due to its causing the inability to see nearby objects clearly. Methods: Patients aged between 3 and 18 years diagnosed with CP were analyzed. Two dynamic retinoscopy techniques were used: the Monocular Estimate Method (MEM) and the Merchán Method. Results: 41 patients with CP aged between 3 and 18 (average age 7.61 years +/- 4.777 SD) were analyzed. Twenty were male and twenty-one were female. Thirty-nine patients (95%) had spastic CP, two patients (5%) had mixed CP (athetoid and spastic). Analyses of variance were carried out in order to compare dioptre measurements for patients with CP to those of patients without CP, finding an average in lag of accommodation of >1.50D (p < 0.0001) for children with CP in both techniques. Discussion: A decrease in accommodative response was observed in children with CP compared to the results of the group of healthy children in both dynamic retinoscopy techniques. Conclusion: We could interpret the deficiency in accommodation as a limitation in the capacity of learning. It would be interesting to analyze whether or not there is an improvement in the development and advancement of their intellectual capacity based on the fact that the majority of activities carried out by children with CP are close work.

Electronic Poster 32 Pediatric Idiopathic Intracranial Hypertension: A major Review Rahul Bhola Noura Estephane Michael Sowell Ian Mutchnick Eric Downing Pradeep Sharma University of Louisville, Louisville, Kentucky Introduction: Idiopathic Intracranial Hypertension (IIH) is characterized by signssymptoms of increased intracranial pressure in absence of space-occupying lesion. Even though it is recognized among pediatric population the clinical characteristics in this population are not well described. We performed a multi-team approach to better understand this disease in pediatric population. Methods: We performed a retrospective chart review of pediatric patients diagnosed with IIH over an eight-year period. Of 110 identified patients in our database, 78 meeting the eligibility criteria were included. Main outcome variables included demographic characteristics, presenting symptoms, medical/ surgical treatment, long-term visual outcomes and recurrences. Results: The mean age of onset was 11.92 ± 4.09. Of the 78 patients 70.5% were females with a strong female preponderance in adolescents (92.5%) but no gender preference in patients younger than 12 years. Ninety-percent of adolescent patients were overweight, moderately or severely obese with majority of younger patients having normal weight. Presenting symptoms included headaches (83.3%), blurry vision (48.7%), nausea (41.02%), and photophobia (38.46%). Papilledema was noted on presentation in 91% patients. Nine percent had cranial nerve VI palsy. All patients attempted medical management and 14 patients (18.0%) subsequently underwent surgical interventions. Seven (10.9%) of 64 patients who did not undergo surgical intervention experienced recurrence. Permanent visual-field changes were seen in 25% patients. Discussion: Prepubertal children with IIH have lower incidence of obesity with no gender predilection. Children with IIH usually complain of headaches and blurred vision and are at risk for permanent visual loss. Conclusion: Early diagnosis and prompt management is essential in preventing permanent vision changes in patients with pediatric IIH. 106 Strabismus in patients with cortical visual impairment: observations of spontaneous resolution and outcomes of surgery Nicholas R Binder Jacqueline Kruglyakova Mark S Borchert University of Southern California / Children’s Hospital Los Angeles Los Angeles, CA Electronic Poster 33 Introduction: Cortical visual impairment (CVI) is the leading cause of bilateral visual impairment in children in developed countries and has a high rate of concurrent strabismus (1). This study set forth to examine the rate of spontaneous resolution of strabismus in CVI patients, success rates of strabismus surgery, and present data on baseline characteristics. Methods: Retrospective chart review was performed on patients with CVI and strabismus for 10 years between 10/2003 and 10/2013. Statistical analysis was performed via Fisher’s exact and chi-squared testing. Results: 70 patients with CVI and strabismus were included for review. Four outcome groups were analyzed. 27 patients (38%) had persistent strabismus and were observed without receiving surgery (group 1). 11 patients (16%) experienced spontaneous resolution of their strabismus (group 2). 32 patients (46%) underwent strabismus surgery; 18 (56%) achieved post-operative alignments of 10 prism diopters (PD) or less (group 3), 9 (28%) were 11-25PD (group 4), and 5 (16%) were >25PD (also group 4). A trend towards better vision at the final clinic visit in groups 2 and 3 as compared to 1 and 4 was observed but did not quite reach statistical significance (p=0.08). Discussion: Patients with CVI and strabismus can be observed to have spontaneous resolution of their strabismus. Only 16% of patients undergoing surgery had poor final alignments of >25 PD. Improving vision may be a guideline as to which patients will have acceptable outcomes. Conclusion: Patients with CVI and strabismus show considerable rates of resolution of their strabismus, either spontaneously or through surgery. References: 1. Huo R, Burden S, Hoyt CS, Good WV.

Outcome of Pediatric Patients Referred for Papilledema Jessica J Kovarik MD Poonam N Doshi MD Janine E Collinge MD David A Plager MD Indiana University, Indianapolis, Indiana Introduction: Referrals for suspected papilledema are common in pediatric ophthalmology practice, though few patients are found to have true papilledema. The purpose of this study is to determine the prevalence of papilledema versus pseudopapilledema among children referred for suspected papilledema and to identify factors differentiating the two diagnoses clinically. Methods: This is a prospective, cross-sectional analysis of patients <18 years old referred to a pediatric ophthalmology clinic by other physicians or optometrists for suspected papilledema by ophthalmoscopic exam between April 2012 and February 2014. Patients underwent detailed ophthalmologic and, when indicated, neurologic evaluation to determine the presence or absence of papilledema. Results: A total of 34 patients were identified. 26/34 patients were diagnosed with pseudopapilledema or normal variant. 2/34 patients were diagnosed with papilledema. 6/34 were diagnosed with unrelated or indeterminate etiology. Headache was a presenting symptom in 25/34 patients. 5/34 patients complained of additional symptoms suggestive of increased intracranial pressure (ICP); two of those five were the patients diagnosed with papilledema. Discussion: The majority of patients referred had pseudopapilledema or a normal variant. Among our population, headache was a common, nonspecific symptom in most patients, whether they had papilledema or not. However, symptoms suggestive of increased ICP were rarely seen in patients without papilledema. Conclusion: This study suggests that in asymptomatic children, a diagnosis of papilledema is unlikely. A detailed history and examination coupled with non-invasive testing, such as ultrasonography, is usually sufficient to diagnose papilledema from other abnormal appearing optic nerves. 107 Electronic Poster 34 Electronic Poster 35 Correlation of Optic Nerve Sheath Diameter Using B-scan Ultrasound with MRI Anatomy in Pediatric Patients Ellen R Miller, David L Rogers, Lisa Martin, April Logan Nationwide Children’s Hospital Columbus, Ohio Introduction: The purpose of this study is to determine the correlation of B-scan ultrasound optic nerve sheath diameter (ONSD) measurements with high resolution orbital MRI in pediatric patients. Methods: This is a prospective study on pediatric patients scheduled to have an MRI. A supine B-scan was performed on both eyes within 30 minutes of MRI. Independent measurements of the vertical ONSD were then performed by the ophthalmologist on the B-scan image at 3, 6, and 9 mm posterior to the papilla. A radiologist performed similar measurements of the ONSD on MRI. Results: Ten patients, ages 5 to 17 are included. A measures model with compound symmetry was used to determine if the two modalities correlate. The difference between the average ONSD measurement in the right eye by ultrasound and MRI is 1.13 mm at 3 mm (p=0.0085). MRI is larger at this point. Ultrasound measurements then progressively increase, with a difference of 1.28 mm and 2.71 mm at 6 and 9 mm (p<0.0001). Left eye results have larger MRI measurements at 3mm, a difference of 0.71 mm (p=0.0778), with increasing ultrasound measurements by 1.22 mm (p=0.0001) and 2.39 mm (p<0.0001) at 6 and 9mm. The differences between the modalities at all three points are statistically significant, except for left eye at 3mm. Discussion: As the distance from the globe increases, the ultrasound ONSD measurements increase relative to MRI measurements. Conclusion: B-scan ultrasound is a useful in-office tool for obtaining various ophthalmic images, but is unreliable in providing anatomically accurate measurements of the ONSD. Electronic Poster 36 The Post-Concussion Syndrome: Influence on Binocular Function Gill Roper-Hall DBOT Oscar A Cruz MD Sophia M Chung MD Saint Louis University 1755 S. Grand Blvd, St. Louis. MO 63104 Introduction: The post-concussion syndrome encompasses a constellation of findings including convergence paresis, disequilibrium and cognitive changes. Ocular symptoms may be exacerbated by head movement or motion. Associated findings include memory loss, difficulty concentrating, and depression. There has been recent media interest in the long term effects of sports-related concussion, particularly repeated concussions. 1-3 Methods: A retrospective study was conducted at our institution of adult patients evaluated and treated between 2002 and 2012 for binocular symptoms occurring after concussion. Exclusion criteria were previous strabismus, concurrent ocular injury, facial or orbital fracture, or vision loss. Results: Eight patients met the inclusion criteria; 5 females and 3 males aged 22 to 51 (mean 35.1). Convergence near point and amplitudes were decreased in all patients. Accommodation was decreased in 5. Pupils were normal. Initial symptoms included blurred vision, asthenopia and headache (8), diplopia (7), cognitive difficulty (7), nausea, dizziness or disequilibrium (6), photophobia or hyperacusis (5). Initial response to convergence therapy was slow despite a modified approach, especially in the motion-intolerant group, necessitating deferred treatment for several months. Full recovery following therapy (1); normal convergence function but persistent concussion-related symptoms (3); partial improvement with no further recovery (4). Discussion: Concussions or ‘mild’ traumatic brain injuries, while not life-threatening, can have lasting effects on a patient’s ability to function at work or in daily life. Convergence paresis is common and should be differentiated from convergence insufficiency. Conclusion: Binocular management techniques after concussion should be modified and simplified in face of associated cognitive and otoneurological signs. Rest is an important adjunct to therapy.

A 7-year follow-up study of 28 cases. Jon Peiter Saunte MD Department of Ophthalmology, Copenhagen University Hospital Glostrup Copenhagen, Denmark Electronic Poster 37 Introduction: Pediatric ocular trauma caused by airsoft gun (ASG) pellets often result in serious ocular injury(1,2,3), but sparse data on persisting ocular damage are available. We wanted to evaluate long-term ocular effects of this trauma mechanism. Methods: A follow-up ophthalmological evaluation of 28 patients with prior ASG ocular trauma. The fellow eye served as control. Results: Of 33 patients with prior documented ASG ocular injury at mean 13 years-of-age(2), 28 (26 male, mean age 20 years, range 8-31 years) were able to participate in a follow-up study at mean 7 years (range 4-9 years) later. 9 suffered from reading problems(CI:0.16-0.52), 11 of photophobia(CI:0.22-0.59), 3 of blurred vision(CI:0.02-0.28), 3 of decreased monocular color vision(CI:0.02-0.28), 2 of ocular discomfort(CI:0.001-0.24), and 2 of cosmetic disturbing anisocoria(CI:0.001-0.24). Automated visual field perimetry was possible in 26 patients, and was abnormal in 8 trauma eyes(CI:0.14-0.52). Accomodation deficit of more than 2 cm compared to the fellow eye was found in 8 patients measured by the RAF ruler(CI:0.13-0.49). Gonioscopy was possible in 24 patients, and angle recession was present in 18 trauma eyes(CI:0.53-0.90). Slitlamp examination revealed traumatic anterior capsular cataract in 5 eyes(CI:0.06-0.37), and retinal exam revealed 5 trauma eyes with focal retinal atrophy(CI:0.06-0.37). Discussion: Former studies have documented acute ocular morbidity in ASG pellet injuries(1,2). This study reveals serious ocular long-term pathology in eyes with serious damage to the trabecular meshwork, lens or retina. Conclusion: ASG pellets frequently cause persisting ocular injury in the pediatric population, with an increased long term risk of developing glaucoma, cataract or retinal pathology.

Mai Tsukikawa Sara E Lally MD Carol L Shields MD Ralph C Eagle MD Barry N Wasserman MD Wills Eye Hospital, Philadelphia, Pennsylvania Introduction: Idiopathic orbital pseudotumor is a noninfectious and non-neoplastic clinical syndrome characterized by the presence of an inflammatory mass within the orbit. Orbital pseudotumor has been observed in association with systemic inflammatory diseases. We present three cases of orbital pseudotumor occurring months to years before the systemic disease. Methods: Clinical records of patients with orbital pseudotumor seen at the Ocular Oncology Service were reviewed retrospectively, and those associated with systemic inflammatory disease were selected for further analysis. Results: We describe three pediatric cases in which isolated orbital pseudotumor preceded the diagnosis of a systemic inflammatory disease. Our first case was 2-year-old white female who presented with right upper eyelid (RUL) swelling secondary to orbital pseudotumor. One year later, the patient developed pauciarticular juvenile idiopathic arthritis (JIA) with anterior uveitis. Our second case was an 11-year-old Hispanic female who presented with RUL swelling and was subsequently diagnosed with orbital pseudotumor. Nine months later, the patient developed a right-sided renal mass, and was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA). Our third case was a 12-year-old white female who presented with right orbital pseudotumor. Four months later, the patient was diagnosed with granulomatosis with polyangiitis (GPA). Discussion: Orbital pseudotumor may be the initial presentation of systemic inflammatory disease in some children. Earlier diagnosis of systemic inflammatory disease might be possible if suspicion is raised after presentation of pediatric orbital pseudotumor. Conclusion: Closer observation and suspicion may be warranted in children with idiopathic orbital pseudotumor. References: 1.

Methods: Retrospective descriptive study. Pediatric patients with DS were selected out of all patients attending their pediatric health supervision at a local hospital which underwent at least one ophthalmological evaluation between 2009 and 2013. Patients who were examined during hospitalization, had incomplete ophthalmological evaluations or were older than 17 years at the time of evaluation, were excluded. Patient records were examined in order to obtain the frequency of different ophthalmic pathologies. Results: 202 met the inclusion criteria. Median patient age was 2 years and 6 months (range, 1 month to 17 years), 48,1% were male. 20,2% of patients presented myopia (>/= -0.50D), 58,9% had hyperopia (= 1,00D) and 63,3% suffered from astigmatism (>/= 0,75D). 30,1% of patients were prescribed glasses. 19,8% presented horizontal strabismus and 0,9% presented vertical strabismus. 2,9% of patients underwent surgery for their strabismus, for which successful results were attained in 100% of cases. 15,3% of patients had nystagmus. 2,5% of patients had cataracts, 21,2% showed nasolacrimal duct obstruction. Overall 94,5% of subjects presented ophthalmic pathology. Discussion: Our research demonstrated a high prevalence of ophthalmic pathologies for this group, showing comparable figures to what has been previously reported in international literature. Conclusion: These results confirm the importance of designing structured ophthalmological evaluation protocols for these patients.

Electronic Poster 40 Eye and systemic manifestations of Moebius syndrome Juan C Juárez-Echenique Ana M Borbolla-Pertierra Vanessa Bosch-Canto Juan C Ordaz-Favila Pedro Acevedo-González National Institute of Pediatrics Insurgentes sur 3700, Letra C, Delegación Coyoacán. Distrito Federal 04530 Introduction: Moebius syndrome is characterized by damage in the nucleus of the sixth and seventh cranial nerves, with subsequent facial palsy and abduction limitation of the eyes. The aim of this article is to describe the ophthalmological findings of the Moebius syndrome in Mexican children. Methods: A cross-sectional, retrospective, observational and descriptive study was conducted. A review was made of the clinical charts of patients with Mobius syndrome who were seen in the National Institute of Pediatrics in Mexico, between the years 2000 and 2010. Results: A total of 64 charts were reviewed. The most important findings were eye abduction limitation (100%), facial palsy (100%), esotropia (54%), epicanthus (51.5%), entropion (22%), and history of use of abortion inducers in the mother in the first trimester of pregnancy (28%). We also found exotropia and hypertropia in some cases. Discussion: Moebius syndrome is a rare cranial nerve disease associated with other systemic anomalies.In Mexico the most frequent findings are 6th and 7th cranial nerve palsy, and therefore esotropia. Almost 30% of the patients were products of mothers that attempted to abort them. Entropion was not reported in previous series. Conclusion: Moebius syndrome has a wide spectrum of ophthalmological manifestations that are important to detect early in order to improve function and esthetics. 110 Is it Usher Syndrome? Diagnosing children with hearing loss and ocular findings. Ashley S Ko MD Wanda L Pfeifer OC(C), COMT Arlene V Drack MD Department of Ophthalmology and Visual Sciences, University of Iowa Iowa City, Iowa USA Electronic Poster 41 Introduction: Because approximately 10% of children with hearing loss have Usher syndrome, hearing impaired children are often referred for ocular evaluation. We studied referring and final diagnoses in children with hearing loss to determine the most effective work up. Methods: IRB-approved retrospective chart review of patients presenting between 20082014 was performed. Data collected included referring and final diagnoses, ophthalmic examination, hearing loss correction, work-up tests and results. Results: 17 patients were identified;11 male, 6 female. Age at referral averaged 5.9 years (8/12 -30 years). Visual acuity averaged 20/58 Snellen, (LogMAR 0.46). 4/17 patients had nystagmus. 5/17 had cochlear implants, 9/17 had hearing aids. Referring diagnoses included Usher(9), nystagmus(3), dominant optic atrophy (DOA)(1), optic nerve atrophy(1), cone dystrophy(1), fourth nerve palsy(1), and ocular apraxia (1). Work-ups included ERG, MRI, and molecular genetic testing. 15/17 had OtoScope testing for hearing-loss genes. 12/15 had at least one Usher mutation found; 7/15 had 2 mutations found, confirming Usher. Final diagnoses were Usher(7), Waardenburg(3), DOA(1),Baraitser-Winter, Harboyan, and Cowshock syndromes(1 each), LCA(1), deletion/ duplication(1), unknown(1). Discussion: Multiple polymorphic genes cause Usher syndrome, and many unaffected people are carriers but do not have Usher. Waardenburg syndrome may present like Usher with decreased vision and hearing loss, but is autosomal dominant rather than recessive and stable rather than progressive. Conclusion: Usher syndrome is the most common eye-ear genetic disorder, but others must be considered. ERG is helpful but not diagnostic. Molecular genetic testing is vital and requires family blood samples and detailed analysis of DNA variants. Prevalence and Clinical Characteristics of Ocular Disease in Children with HIV/AIDS Taliva D Martin MD Maya S Ling MD Emmett T Cunningham MD, PhD, MPH Ann Petru MD Susan H Day MD California Pacific Medical Center San Francisco, CA, USA UCSF Benioff/Children’s Hospital Oakland, Oakland, CA, USA Introduction: Describe the prevalence and clinical characteristics of ocular disease in children with HIV/ AIDS. Methods: Charts of patients less than 18 years old followed at the HIV/AIDS clinic at UCSF Benioff/ Children’s Hospital Oakland between March 2012 and May 2014 were reviewed. Patients who consented for the study underwent an eye examination by a pediatric ophthalmologist. Results: Charts of fifty patients were reviewed. Thirty-six (72%) underwent an eye examination, including 19 (52.8%) girls and 17 (47.2%) boys. Age at the time of examination ranged from 3 to 17 years, with a mean and median of 11.4 years and 11.0 years, respectively. Mean and median CD4 count were 814.4 cells/microliter and 772.5 cells/microliter, respectively. 31 (86.1%) patients had a visual acuity at last visit of 20/20. Four (11.1%) patients had interpalpebral conjunctival injection, and 1 each (2.8%) had an accommodative esotropia, an intermittent exotropia, congenital ptosis, peripheral lattice degeneration, retinal scars from previous treatment of retinopathy of prematurity, hypopigmented retinal lesions, hyperpigmented retinal lesion, and HIV-associated retinal vasculitis and optic neuropathy. Six of the 12 patients with ocular findings (50.0%) were born outside of the United States. Discussion: Ocular complications of HIV/AIDS are less common in children compared to adults. The prevalence of ocular disease in our referral cohort (33.3%) was consistent with other studies. Conclusion: Ocular complications of HIV/AIDS are uncommon in children infected with HIV.

Methods: Ninety-one children with DS aged 0 to 11 years and 91 age-matched and gender-matched healthy control subjects (HCS) from same ethnic backgrounds were enrolled in the study. Intraocular pressure (IOP) was measured by induction/impact rebound tonometry and expressed in mmHg. Both eyes of each child were analyzed. Repeated measures using two-sample unpooled t-test with unequal variances were used and a Pvalue <0.05 was considered statistically significant. Results: Patients from each comparative group were divided into 3 subgroups according to their age. Sixty-two patients in group A and B (0-3 years old) and (4-7) respectively and 54 in group C (8-11). Mean IOP for group A was 10.58 in right eye (RE) and 10.65 in left eye (LE) in DS children, compared to 12.68 RE and 13.28 LE in HCS. Mean IOP for group B was 13.28 RE and 11.65 LE in DS children, compared to 14.28 RE and 15.12 LE in HCS. Mean IOP for group C was 11.70 RE and 11.88 LE in DS children, compared to 15.66 RE and 15.70 LE in HCS. Discussion: Mean IOP in DS children of all groups (11.68±4.06) was significantly lower (p<0.05) than the HCS (14.48±4.39). Conclusion: Children with DS had decreased IOP compared with HCS. No previous studies have reported IOP measurements in children with DS. Rebound tonometry provides useful ophthalmological information in these patients in which standard tonometry is difficult to perform. References: 1)Evereklioglu C, Yilmaz K, Bekir N.

Electronic Poster 44 Novel Technique for the Repair of Large Upper Eyelid Colobomas Alexandra T Elliott MD Children’s Hospital Boston Boston, Massachusetts Introduction: Large eyelid colobomas that affect between 50%-75% of the upper eyelid present a management challenge due to lack of sufficient tissue for repair. A novel approach to its repair resulting in excellent cosmesis and absence of induced astigmatism will be presented. Methods: A case series of three infants who underwent this proceedure were reviewed. Results: All three had superior cosmetic results and absence of induced astigmatism. All skin grafts were healthy and indestinguishable from surrounding tissues. Discussion: Full thickness skin grafting in children is notorious for poor healing and tissue mismatch. In this technique where the graft is harvested from the resected colobomatous tissue there is no tissue mismatch. By dividing anterior and posterior lamella but leaving middle lamella intact, graft is well perfused and astigmatism secondary to tight postoperative eyelid is avoided. Conclusion: Autogenous skin graft from colobomatous tissue when comined with middle lamella preservation offers superior cosmetic and functional results to children with large upper lid colobomas. This technique is an improvement over traditional rotational flaps. 112 Multi-tool instrument decreases complications with nasolacrimal intubation Celia Haering Robert W Arnold Alaska Blind Child Discovery Anchorage, Alaska Electronic Poster 45 Introduction: Silicone stenting is a recognized method for treatment of nasolacrimal obstruction (NLD) and canalicular laceration. Despite several variations in surgical techniques, complications including wire-stripping of the stent, premature dislocation, and re-operation persist. A combined surgical instrument was designed in hopes of simplifying Farson bilateral-monocanalicular Crawford intubation. Methods: In an ongoing IRB study with >12 months follow-up, 716 cases of tear duct care by one surgeon over two decades were evaluated for complications before and after use of a new surgical instrument- the nasolacrimal dilator-rasp. Results: 493 cases of NLD had Farson modified Crawford tube- 356 with the new dilator rasp. 146 had conventional Crawford tube, 53 had probing (21 dacryocystoceles), 18 had canalicular lacerations, 2 DCR, 3 fistula excision and 1 Lacricath. Of Farson cases comparing 137 past to 356 new instrumentation, absent puncta treated 1:10 times, wirestripping 2:2 times, re-operation 4:6 cases. Discussion: For cases of NLD, the nasolacrimal dilator-rasp and the Farson Crawford tube can achieve 98% success (no re-op) despite no in fracture of the turbinates. Parents easily remove the stent at home. Conclusion: The nasolacrimal dilator-rasp can simplify tear duct surgery.

At times hooking the silicone tube from under the inferior conchae can be difficult, time consuming and traumatic. Occasionally silicone tubes can be found in and rescued from the pharynx. We describe herein our method of tube retrieval from the pharynx. Methods: Surgical technique description Results: Our new suggested technique is to be used in cases in which the self-threading Monoka is easily pushed through the Ritleng probe into the nasal cavity but cannot be hooked from under the inferior conchae. After unsuccessful hooking of the silicone tube we ask the anesthesiologist to look into the Pharynx with a laryngoscope searching for a wire. If the wire is visualized, the Anesthesiologist uses Magill forceps to pull the wire through the patient’s mouth. We then use a funneled suction catheter, which is transferred through the nose into the pharynx and then pulled out of the mouth. The edges of the suction catheter and the Monoka silicone tube are tied together and then the suction catheter is pulled back through the nose with the edge of the silicone tube. The silicone tube is then cut short and is left to pull back into the nose. Discussion: The technique we described is simple, inexpensive and time saving at those cases in which hooking of the silicone tube from under the inferior conchae is difficult and the edge of the silicone tube is observed in the pharynx. Conclusion: see discussion 113 Electronic Poster 46 Electronic Poster 47 Canalicular laceration repair with a novel viscoelastic injection technique to locate and dilate the proximal torn edge Faruk H Orge University Hospitals of Case Medical Center, Department of Ophthalmology Cleveland, Ohio Introduction: Canalicular lacerations are common complications of eyelid trauma in the pediatric population. Irrigating air, water, colored or viscous agents through the intact canaliculus have been suggested to make locating the torn proximal edge easier. We report our experience in repairing canalicular lacerations using a novel viscoelastic injection technique with a Monoka monocanalicular stent. Methods: Patients under the age of 18 who underwent repair of a canalicular laceration with a monocanalicular stent using a novel viscoelastic injection technique at our institution were retrospectively reviewed. Demographics, cause of eyelid injury, surgical management using our novel viscoelastic injection technique, and its outcome were analyzed. Results: After reviewing 38 children with lid lacerations, 17 children (mean age = 6.27 years) who had canalicular injury due to dog bites (9 patients) and shearing trauma (8 patients) were included the study. Locations of injury included 11 lower lids, 4 upper lids, and 2 combined upper and lower lids. All patients had good anatomic repair and on follow up had negative dye disappearance tests and were free of tearing. Discussion: In our institution’s experience deploying viscoelastic in the vicinity of and injecting into the injured canaliculus has proven a useful technique. Conclusion: The technique improves visualization of the operative field by retracting the anatomy and tamponading any bleeding, aids in location and dilation of the torn canaliculus initially and in subsequent steps, eases intubation into the lubricated torn canaliculus and nasolacrimal duct, and avoids iatrogenic injury to an uninjured canaliculus. Electronic Poster 48 Analysis of the Readability of Patient Education Materials in Pediatric Ophthalmology Ann M John BA Elizabeth S John BA David R Hansberry MD, PhD Suqin Guo MD The Institute of Ophthalmology and Visual Science, Rutgers New Jersey Medical School Newark, NJ Introduction: Patients increasingly utilize online resources for healthcare information. Studies show that over eight in ten caregivers have Internet access, and 84% of them search online for health information(1). The American Medical Association (AMA) and National Institute of Health (NIH) recommend that online patient resources be written between a 3rd and 7th grade-level for sufficient patient comprehension(2,3). This study assesses whether online health information in pediatric ophthalmology abides by these guidelines. Methods: Ten pediatric ophthalmology conditions were entered into a commonly used search engine, Google.com(1). Conditions included amblyopia, cataract, conjunctivitis, corneal abrasion, nystagmus, retinoblastoma, retinopathy of prematurity, sty, and glaucoma. The first ten patient information articles for each condition were assessed using 10 validated readability scales: FleschReading Ease, Flesch-Kincaid Grade-Level, SMOG Grading, Coleman-Liau Index, Gunning-Fog Index, New Dale-Chall, FORCAST, Fry graph, Raygor-Estimate, and New Fog-Count. Scientific articles and articles written on patient forums were excluded. Common sources of articles were aapos.org, aoa.org, kidshealth.org, and geteyesmart.org. Results: The majority of articles were written above recommended guidelines. Across all scales, the 100 articles were written at a mean grade-level of 12.1±1.8. Only 12% of articles were written below a 9th grade-level and only 2% met recommended criteria. Discussion: The readability of online patient education material exceeds NIH and AMA guidelines. This can adversely affect caregiver comprehension of such resources, contributing to poor decision-making. Conclusion: Pediatric ophthalmology online articles are generally written at a level too high for caregiver comprehension. Revision of the level of articles may increase patient education, improve health outcomes, and facilitate the patient-physician relationship. References: 1. Fox S, Duggan M, Purcell K.

We assessed the impact of the transition from paper charts to EMR in a pediatric ophthalmology practice at a tertiary care center. Methods: Prospective, cross-sectional survey. Patients/guardians completed a questionnaire consisting of ten Likert-type scaled questions and two free response questions at three time points: two weeks prior to (phase 1), two weeks after (phase 2), and three months after (phase 3) the EMR transition. Results: A total of 382 surveys were collected: 158 from phase 1, 68 from phase 2 and 156 from phase 3. The survey response rate was 92%, 85% and 93% for phase 1, 2 and 3 respectively. Overall, patient satisfaction was high at all three time points. Of significance, the patients’ preference for the EMR over paper charts increased in phase 3 compared to phase 2 (p=0.022). The time between check-in and physician entering the room was significantly longer in phase 1 and phase 3 when compared to phase 2 (133 versus 102 minutes, p=0.0019; 139 versus 102 minutes, p=0.0004). Physicians spent significantly more time with the patient in phase 2 as compared to phase 3 (31 vs 18 minutes, p=0.001). Patients’ estimates of waiting time compared to actual waiting time were not significantly different at any phase; however, patients’ estimates of time spent with the physician were significantly underestimated in phase 1 (20 versus 25 minutes, p=0.04) and overestimated in phase 3 (24 versus 18 minutes, p=0.0002). Discussion: Most patients were satisfied with the service regardless of use of paper chart or EMR. The EMR does not seem to improve patient’s waiting time, but seems to have a significant impact in the perception of time spent with physician. Conclusion: Transition to EMR does not seem to impact patient wait time. Time spent with the patient increased during transition and normalized after mastery of the system, although patients continued to perceive longer time spent with the physician long after transition to EMR.

West, MD, Mary Anne Lenk, BS, Brandy L. Dearwater, RN, Christopher S. Byington, MHSA, Kelli Vieson, COT, William W. Motley, MD Cincinnati Children’s Hospital Medical Center and the University of Cincinnati College of Medicine Department of Ophthalmology, Cincinnati, Ohio Introduction: Differences in inter-patient complexity lead to variability of total physician time per patient, with adverse effects on both patients’ and physician’s experience and flow. We sought to improve scheduling accuracy by determining if simple linguistic features contained in an electronic health record (EHR) could predict total physician time per patient. Methods: The Davis Observation Code(1) and the methods of Fiks et al(2) were adapted to measure and characterize time spent by a pediatric ophthalmologist at various tasks, including documentation in an EHR, in a hospital-based pediatric ophthalmology practice. A Delphi approach was utilized to achieve consensus about which linguistic features in a patient’s EHR record signal increased physician time. Physician time per patient was recorded by an observer masked to presence/absence of identified linguistic features during two clinic days. Results: Linguistic features identified that signaled above-average (“Extended”) physician time included: ‘glaucoma’, ‘cataract’/’aphakia’/’pseudophakia’, ‘nystagmus’, ‘Trisomy 21’, ‘second opinion’, and ‘surgical consult’. Mean total physician time for ‘Extended’ patients (n=11) was 1165 sec (SD 388 sec), while mean physician time for patients lacking identified linguistic features (n=34) was 764 sec (SD 277 sec); p-value <0.0001. Our results enabled us to derive a mathematical model to optimize appointment schedule templates that account for varied patient complexity. Discussion: Simple linguistic features in an EHR can be utilized to accurately predict and account for physician time per patient based on anticipated patient complexity. Conclusion: This work provides proof-of-concept for inclusion of decision support approaches involving textual data, such as natural language processing, in an EHR. References: 1.

Methods: Medications used to treat visually threatening disorders were selected. They include: amblyopia (atropine), juvenile idiopathic arthritis (prednisolone, difluprednate, loteprednol, rimexolone), bacterial keratitis (moxifloxacin, gatifloxacin, ofloxacin, levofloxacin, ciprofloxacin, besifloxacin), herpetic keratitis (acyclovir), pediatric glaucoma (oral acetazolamide, latanoprost, dorzolamide-timolol, dorzolamide, brinzolamide), infantile hemangioma (oral propranolol), ophthalmia neonatorum prophylaxis (erythromycin), and ROP (intravitreal bevicizaumab). We reviewed the FDA status of each medication and compared this to the guidelines found in AAO, AAPOS, AAP and Cochrane. Results: 3/20 medications were FDA-approved for the indication in children of any age. 3/20 medications were FDA-approved for the indications but not proven safe in children under 1 or 2 years of age. 14/20 medications were not FDA-approved for the indication and/or not recommended for pediatric use. Current guidelines supported, to some extent, the use of all 20/20 medications for the selected indication and specifically mentioned use in children for 8/20 medication. Discussion: A divergence exists between FDA status and current guidelines for medications used in pediatric ophthalmology. Guidelines support a broader range of medications used for pediatric ophthalmologic conditions than FDA status would suggest. Conclusion: The FDA status of several medications used in pediatric ophthalmology is more restrictive than what is suggested by current medical guidelines. Medical guidelines should be considered when treating pediatric ophthalmic conditions. Future FDA classification may consider current medical guidelines in pediatric ophthalmology and other fields of medicine. Electronic Poster 52 Establishing a surgical outreach program in the developing world: pediatric strabismus surgery in Guatemala City, Guatemala Lauren C Ditta Emily T Graves Chantel Devould Ebony Murchison Natalie C Kerr University of Tennessee, Hamilton Eye Institute Memphis, TN Introduction: Organizing a sustainable pediatric surgical outreach mission to an underserved population in a foreign country presents unique challenges for the pediatric ophthalmologist. Methods: During Fall of 2013 and 2014, we organized a pediatric ophthalmic surgical outreach mission for strabismic disorders in Guatemala. In year one, patients were referred by local healthcare providers. In year two, greater than 60% were pre-screened by a local pediatric ophthalmologist prior to referral. Children were evaluated for surgical intervention by three pediatric ophthalmologists and an orthoptist. Surgical care was provided at the Moore Outpatient Surgical Care Facility in Guatemala City, Guatemala over four days. Results: We screened 47% more patients in year two (90 vs. 132). Patient age range (1-17 years). Diagnoses included congenital and acquired esotropia, consecutive and acquired exotropia, congenital nystagmus, Duane’s syndrome, and oblique muscle dysfunction. We performed 18 more surgeries in our second year (40 vs. 58), a 45% increase. Three patients from year one returned for additional treatment. Of these, one was over-corrected. There were three additional immediate post-operative over-corrections. There were no significant complications during anesthesia, surgery, or in the immediate post-operative period. Discussion: Each year, 44% of screened patients underwent surgery, suggesting that despite screening a larger volume of patients, a similar incidence of surgical pathology was identified. Conclusion: International cooperation, a multidisciplinary team of healthcare providers, and equipment allocations provide a safe and effective surgical outreach program for children with strabismus in the developing world. Coordinating pre and post-operative care with a local pediatric ophthalmologist facilitates best practice management and sustainability.

The purpose was to investigate the ophthalmologic outcome of extremely preterm children (EPT, <27 weeks) at 6.5 years Methods: A population-based cohort of all EPT children (n=496) born in Sweden 2004 - 2007 was assessed and compared with a term-born control group, as part of a prospective national follow-up study.1 Visual and stereo acuity, refraction and manifest strabismus were evaluated. Results: At a median age of 79 months 430 of 496 eligible EPT children (87%) were assessed (73 by chart review) and 296 controls. In the EPT group subnormal visual acuity was found in 15.0%, visual impairment in 2.6% and blindness in 2.1% versus 0.7%, 0.3% and 0% in the control group. Hyperopia (> 3D), myopia (</= -3D), astigmatism (< -2D) and anisometropia (>/= 2D) were found in 17.6%, 5.2%, 8.4% and 8.8% respectively in the EPT group as compared to 4.2%, 0%, 1.8% and 0.4% in the control group, and manifest strabismus in 14.1% versus 0% in the controls. Stereo acuity was deficient in 43.8% of EPT children and in 4.7% of controls and was negative in 22.6% vs 1.0%. All group differences were highly significant with p-values <0.001 (Mann-Whitney U test). Discussion: Ophthalmologic outcome will be discussed in relation to ROP, GA, BW and cognition. Conclusion: A Swedish population based three years cohort of extremely preterm children at school-age have significantly affected ophthalmologic outcomes as compared to age-matched controls.

Methods: Retrospective chart review was conducted of patients evaluated by the ophthalmology consultation service from January-March 2014. Patient charts were abstracted for data related to reasons for consult and findings/recommendations made. Results: 379 patients were evaluated, 72 (19.0%) children and 307 (81.0%) adults. More children (38.9%) than adults (7.5%) were seen with an attending (p<0.001). More adults (81.1%) than children (61.1%) had an eye complaint (p<0.001). More adults (92.2%) than children (76.4%) had abnormal findings on exam (p<0.001). The other variables were not significantly different: an alteration in management was recommended for 50% of patients; outpatient follow up was recommended for 70% of patients. Discussion: There are several differences between pediatric and adult consults in our institution. More adult patients had a chief complaint, because many pediatric exams were done to screen for systemic diseases or non-accidental trauma. Many of these screens result in negative examinations, which explains why more of the adult patients had abnormal findings. Despite the higher rate of abnormal findings in adults, patient management was changed at similar rates among children and adults. Conclusion: Comparing pediatric and adult consults allows for the identification of patterns among both providers and patients. These patterns can be used to help educate primary care physicians and ophthalmology residents on the best management of inpatient consults. 117 Electronic Poster 54 Electronic Poster 55 The Effectiveness of a Mobile Clinic in Improving Follow-up Eye Care for At-Risk Children Jinali Patel MD Wei Diao BA Melanie Snitzer MSW, LSW Michael Pond BA Rachel Weiner BS Sarah Martinez-Helfman BS Kathleen Santa Maria COT Alex V Levin MD, MHSc Wills Eye Hospital 840 Walnut Street, Philadelphia PA 19107 Introduction: Every year over 22,000 Philadelphia public school students fail a school vision screen but only approximately 4,000 see an ophthalmologist. While mobile optometric care units have had success in delivering primary eye care, only 53% of patients referred to pediatric ophthalmologists complete this consultation. This study investigates whether a mobile eye unit with the same equipment as a pediatric ophthalmologist’s office could improve the rate of successful consultation. Methods: Cohort study of students from schools in socioeconomically disadvantaged communities, referred to a mobile ophthalmic unit after failing an in-school optometric exam and obtained consent to be seen by a mobile unit instead of at a local hospital. Results: 132 students were referred by the optometric program to the mobile unit. 101 students had signed consent forms of which 82 (81%, CI 74%-89%) were seen by the mobile ophthalmic unit, which represents a follow-up rate of 62% (CI 54-70%). The rate of successful completions of ophthalmology consultation increased compared with the historical rate of 53% (p=0.036). School nurses responded favorably to this program citing improved convenience, simpler logistics, and more effective use of personnel time. Discussion: Our data suggest that a mobile eye unit can increase the ability to successfully provide ophthalmic care to high risk children. Conclusion: As screening without follow-up does not adequately address the needs of pediatric patients, the use of mobile eye clinics in schools may allow consultation completion to be more successful.

Electronic Poster 56 Epidemiology of Pediatric Ophthalmic Trauma Joshua A Schliesser David Lyon Anvesh Reddy Amneet Hans Faheem Mahomed Ruby Parikh University of Missouri - Kansas City Kansas City, Missouri Introduction: Pediatric ocular trauma is recognized as a leading cause of preventable unilateral blindness.1 Anecdotal evidence suggests pediatric ocular trauma increases during summer months. Our study aim is to determine if pediatric ocular trauma occurs more frequently during the summer season and determine how visual outcome varies by seasonality, gender, age, mechanisms of injury, and surgical management. Methods: Pediatric ophthalmology consults for ocular trauma occurring between January 2003 and November 2012 were reviewed retrospectively. Results: 374 patients with eye injuries were evaluated. 255 patients were male and 119 were female (p<0.001). Eye injuries occurred most during the spring and summer months (58.8%, p=0.007). Blunt trauma occurred more frequent than penetrating (78.34 vs 21.66%; p<0.001), with an average age of 10.49±4.48 years and 8.26±4.36 years, respectively (p<0.001), and resulted in better visual acuity (0.16 logMAR vs 0.73 logMAR; p<0.001). Projectile injuries resulted in worse vision (0.68 logMAR vs 0.21 logMAR; p<0.001). Discussion: Eye injuries were observed most in the spring and summer months. Risk factors for poor visual outcome included penetrating trauma, projectile mechanism, and trauma requiring multiple surgeries. Conclusion: Pediatric ocular trauma outcomes vary greatly. By understanding these outcome variables there is potential for improving patient safety and the management of pediatric ophthalmic trauma. References: 1.

Daniel C Terveen Benson S Hsu MD Geoffrey T Tufty MD University of South Dakota Sanford School of Medicine 1400 W 22nd St, Sioux Falls, SD 57105 Electronic Poster 57 Introduction: To determine the impact of insurance status on hospital resource utilization for pediatric ophthalmic inpatients in the United States. Methods: We conducted a retrospective cohort study using 2009 hospital discharge data from the Healthcare Cost and Utilization Project (HCUP) Kids’ Inpatient Database (KID). Pediatric ophthalmic inpatients (n=7,796) age 0-20 were stratified by primary payer status. To assess resource utilization, we used hospital charges as well as assessed length of stay, time to initial procedure, and number of procedures. Results: Pediatric ophthalmic inpatients with Medicaid (n=3,932) had higher total charges than patients with private insurance (n=3,864). Total charges were $20,773 for all Medicaid patients compared to $20,586 for those with private insurance (p<0.001). When comparing Medicaid to privately insured patients we found differences in Length of Stay (3.43 to 3.11 days, p<0.001), Time to Initial Procedure (1.10 to 0.79 days, p<0.01), and Number of Procedures (1.01 to 1.14, p<0.001). There was no difference in Number of Chronic Conditions (0.91 to 0.93, p=0.49). Discussion: Medicaid pediatric ophthalmic inpatients had longer length of stay, longer time to initial procedure, less procedures performed, and higher total charges compared to private insurance patients. Conclusion: Among pediatric ophthalmic inpatients there is a significant difference in resource utilization between the payer types. Patients with Medicaid had the longest lengths of stay and highest total charges even when controlling for patient comorbidities. Our findings suggest that shifting privately insured patients to Medicaid as proposed through the Affordable Care Act could increase costs and resource utilization in this population. Seizures induced by cycloplegic eye drops Tamara Wygnanski-Jaffe MD Paolo Nucci MD Mauro Goldchmit MD Eedy Mezer MD Goldschleger Eye Institute, University Eye Clinic San Giuseppe, Cema Hospital, Rambam Health Center Tel Hashomer, Israel, Milan, Italy, Sao Paulo, Brazil, Haifa, Israel Introduction: The Most dreaded effect of cycloplegic eye drops have been their effect on the central nervous system. The puprose of this study was to assess the incidence of seizures induced by cycloplegic drops. Methods: A survey among members of the American Association for Pediatric Ophthalmology and Strabismus yielded five patients who received cycloplegic eye drops between 1998 and 2010 and who consequently developed a seizure. Results: The median age of the patients was 5 years (range 3 months to 12years). Cyclopentolate hydrochloride 1% was the only causative agent. The seizure occured on average 12 minutes after the instillation of dilating eye drops. Three were generalized convulsions, and two patients had a focal seizure. Past medical history was unremarkable in four cases. Sixteen previous cases of seizures induced by cycloplegic drugs were identified in reports published between 1890 and 2004, implicating atropine in 9 reports,tropicamide and phenylephrine eye drops in 1, and cyclopentolate in 6. Discussion: A small amount of cyclopentolate drops could induce convulsions in young children after only minutes to less than an hour, while a larger dosage of atropine over the span of several hours could cause this rare and unpredictable complication. Predisposing factors were rare and those developing the seizures were healthy subjects. Generalized seizures were much more frequent than focal seizures. Conclusion: Fatel side effects due to cylopentolate drops are extremely rare, they occur shortly after instillation and have no predilection to unhealthy children;therefore there is no reason to fear using cyclopentolate drops.

We used an animal model to evaluate the potential for optic nerve compression (ONC) to cause RH and determine the effects of increased cerebral blood volume (CBV) and intracranial pressure (ICP). Methods: Anesthetized piglets were used as surrogates for 1 month old infants. A custom clamp with transducers to measure force applied ONC sufficient to achieve retinal vascular occlusion, confirmed ophthalmoscopically. Group 1, n=2 eyes, received static ONC alone; group 2, n=3, received static ONC with thoracoabdominal compression (TAC); group 3, n=2, received static and cyclic ONC, with TAC. Indirect ophthalmoscopy and histopathology were performed. Results: Group 1: 1/2 eyes had 3 small blot RH. Group 2: 2/3 eyes had extensive RH, including large nerve-fiber-layer hemorrhagic-schisis/cyst, deeper intra-RH, sub-RH/fluid, ON and disc hemorrhages. Group 3: 1/2 eyes had ON and disc hemorrhages. Clamping force and application rate were not clearly related to RH. Discussion: ONC with TAC presumably caused retinal venous occlusion and extensive RH. ONC may result from traumatic kinking during shaking. TAC has been shown experimentally to simulate known physiological changes (raised CBV/ICP) of crying, which is a primary trigger of infant shaking. Perhaps this combination, along with other physiological or mechanical factors, contributes to RH seen clinically. Conclusion: Multilayered RH can develop in an animal model from ONC combined with TAC. ONC from shaking, raised CBV/ICP, and their thresholds for RH when combined with traumatic retinal venous occlusion or vitreoretinal traction, require further study. Electronic Poster 60 Circumferential Macular Folds Associated with Reduced Macular Hemorrhages in Non-accidental Trauma: Implications for the Theory of Vitreous Traction Alexander E Pogrebniak MD The Nemours Children’s Clinic Jacksonville, Florida Introduction: The direct intraocular mechanisms and forces required to create retinal hemorrhages in non-accidental head injury remain a matter of controversy and conjecture. The predominant theory implicates vitreous traction on retinal vessels; however, retinal hemorrhages occur in other settings without history of rapid acceleration-deceleration injury, such as in healthy newborns. Circumferential macular folds are seen almost exclusively in severe non-accidental trauma. We sought to document the pattern of retinal hemorrhages relative to macular folds to determine if the altered vitreoretinal interface may influence the formation of retinal hemorrhages. Methods: We present a report of two cases of non-accidental trauma with circumferential macular folds to examine the location of hemorrhages related to the macular schisis cavities. Results: As seen in the analysis of photographs, in both cases retinal hemorrhage was almost confluent peripheral to the circumferential macular folds, was prominent on the apex and sides of the folds, but almost absent central to the folds (ratio area hemorrhage peripheral to fold: central to fold > 5:1). Discussion: The pattern of retinal hemorrhages post severe non-accidental trauma appears altered by the presence of retinal folds, with decreased hemorrhage central to the folds where macular schisis has occurred, in contrast to the typical finding of widespread macular hemorrhages when non-accidental trauma occurs without macular folds. Conclusion: The findings may support the theory of vitreous traction causing retinal hemorrhages whereby retinal hemorrhage is prominent on and peripheral to the retinal folds where vitreous attachments persist and minimized central to the folds where schisis has occurred. 120 SPECTRAL DOMAIN-OPTICAL COHERENCE TOMOGRAPHY FINDINGS IN PEDIATRIC TILTED DISC SYNDROME Massimiliano Serafino MD Francesco Pichi MD Simona Romano MD Paola Carrai MD Mariachiara Morara MD Antonio P Ciardella MD Kyoko-Ohno Matsui MD Paolo Nucci MD University Eye Clinic, San Giuseppe Hospital, University of Milan, Milan, italy Electronic Poster 61 Introduction: To report a novel spectral domain-optical coherence tomography (SDOCT) finding in children affected by tilted disc syndrome (TDS), and to correlate it with early visual field defects. Methods: Patients between 5 and 17 years old with TDS were enrolled in this study. The diagnosis of TDS was made by stereoscopic fundus photography. All eyes were examined with 12 radial SD-OCT B-scans of 12 mm centered on the optic disc; the fundus area encompassing the optic nerve was additionally scanned using several vertical and horizontal scans. C-scan SD-OCT were acquired using the Macular Cube 512 x128 to create the en face image. Standard automated perimetry 24-2 tests were performed on all patients. Results: Thirty-eight eyes of 20 pediatric patients with TDS syndrome were enrolled during this 24-months clinical trial. Their mean age was 10.9±2.7 years (range 7-15 years), 12 (60%) were male and 8 (40%) were female. The OCT images of the optic discs showed a protrusion of the upper edge of Bruch’s membrane and choroid at the nasal edge of the optic disc in 39.5% of the eyes. The retinal nerve fiber tissue appeared to be herniated into this protrusion and bent superiorly in 15 eyes. This severe bending corresponded to early visual field anomalies that were not reduced by corrective lenses in 46.7% of the eyes. Discussion: Visual field defects that do not improve by increased myopic correction in TDS may be due to the severe bending of the retinal nerve fiber tissue, which would impair axonal flow. Conclusion: Better understanding of correlation among myopia, optic disc, and visual field defects. Pediatric Ophthalmologists’ Trends in Abusive Head Trauma Evan C Sussenbach MD R Michael Siatkowski MD Kai Ding PhD Tammy L Yanovitch MD, MPH Dean McGee Eye Institute, Oklahoma University Health Sciences Center Oklahoma City, Oklahoma Introduction: To estimate the number of abusive head trauma (AHT) cases seen by pediatric ophthalmologists and analyze factors associated with physician subpoenas and court testimony. Methods: Pediatric ophthalmologists were surveyed about their experience with AHT. The survey was sent to 875 active members of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS). Results: The response rate was 15% (132 surveys). The median pediatric ophthalmologist was consulted 10.0 (interquartile range [IQR] = 4.0-19.0) times per year to evaluate patients for AHT and saw 2.5 (IQR = 1.0-6.0) patients with probable AHT annually. Pediatric ophthalmologists were equally likely to be subpoenaed (4.6% vs. 4.8%, p=0.84) or to testify (1.9% vs. 1.7%, p=0.79) whether they did or did not perform retinal photography. Physicians were equally likely to be subpoenaed (4.8% vs. 7.1%, p=0.92) or to testify (2.2% vs. 0.0%, p=0.17) whether a child abuse team was involved in patient care or not. Geographic location had no statistical significance on how frequently pediatric ophthalmologists were subpoenaed (p=0.17) or testified in court (p=0.12). Discussion: Obtaining retinal imaging, having a child abuse team, and geographic location had no significant relationship to how frequently pediatric ophthalmologists were subpoenaed or testified in court. Conclusion: It is likely that a pediatric ophthalmologist will be subpoenaed and testify in a case of AHT in his or her career. Although the use of retinal photography and child abuse teams assist in documenting and reporting AHT, these factors do not supersede the role of the pediatric ophthalmologist in medico-legal proceedings.

Most countries have screening guidelines but there is little national data on ROP requiring treatment. Collecting epidemiological data on the incidence of treatable ROP, the treatment methods used and facilities for treatment allows for effective planning of resources and manpower. Methods: A prospective epidemiological study of ROP treatment in the UK was started on 1 December 2013. Cases are identified through existing reporting systems by the British Ophthalmic Surveillance Unit BOSU, which sends out a monthly report card to every consultant ophthalmologist in the UK. A special interest collaborative study group (ROP SIG) was set up to facilitate information gathering. A questionnaire identifies ROP stage at time of treatment, treatment method, location, and time to treatment from making the decision to treat. Results: 174 cases were identified in the first 38 weeks: 94 male, 79 female. Mean gestational age was 24.9 weeks (range 23-30 weeks), mean birthweight 728.4g (range 360-1375g). Primary treatment was laser in 160 babies, antiVEGF in 11, cryotherapy in 1 baby. 15/142 were IVF babies. 120 were singletons. Discussion: A previous UK ROP treatment study (1) in 1997-1999 reported on 131 treatments over 15 months. At that time 76% were treated with laser, and 22% with cryo. This study demonstrates an increase in babies undergoing ROP treatment and a significant move away from cryotherapy. Conclusion: This study demonstrates the increased workload from using early treatment guidelines and shows the adoption of newer treatments in ROP management. References: 1.

Electronic Poster 64 Ensuring Successful Enrollment of Premature Babies into NICU based Clinical Studies: Lessons learned from the ‘Telemedicine Approaches to Evaluating Acute-phase retinopathy of prematurity (ROP) - e-ROP’ Study Agnieshka Baumritter Akosua Nti Graham E Quinn MD, MSCE Karen Karp RN, BSN Children’s Hospital of Philadelphia, Philadelphia Introduction: Conducting research on very low birth weight (VLBW) premature infants is challenging. Parents, NICU nurses and physicians are concerned about procedures not deemed essential or directly beneficial. We report enrollment from a multi-center, NEI-funded e-ROP study undertaken in infants with birth weight (BW)<1251g to identify those who need ophthalmological examinations. Methods: Study Certified Coordinators (SCC) at 13 Level 3 NICUs in the US/Canada sought consent to enroll 2,000 preterm babies in a minimal risk study in which babies undergo serial ROP imaging by non-physicians using a wide-field camera, and diagnostic examinations by ophthalmologists. All e-ROP investigators received training in the protocol and consenting techniques, including verbal consent. Accrual monitoring, feedback and incentives were provided to improve enrollment. Results: 1284 babies (mean BW 864g, mean GA 27 wks.) out of 2351 eligible (59.8%) were enrolled with 71.5% at 4 high enrolling (HE) centers compared to 50.4% at other centers. SCC background and time commitment varied across sites, but SCCs at HE centers were more likely to have NICU/ROP experience and be full-time research coordinators with established relationships with neonatology and nursing. Discussion: The e-ROP enrollment rate (59.8%) was higher than most research studies in VLBW infants primarily due to: SCC’s relevant experience (research training, knowledge of preemie status, ROP), time/flexibility (screening for eligibility, direct contact with parents), getting NICU’s buy-in , coordination/sequencing of competing NICU studies. Conclusion: e-ROP study demonstrated the feasibility of enrolling VLBW infants into clinical research and provided lessons for building resonant context for other clinical studies working with high risk populations.

Grace Prakalapakorn, MD, MPH Duke Eye Center, Durham, North Carolina Electronic Poster 65 Introduction: Current U.S. guidelines for retinopathy of prematurity (ROP) screening require retinal examinations for at-risk infants be performed by an ophthalmologist with sufficient knowledge and experience to identify serial changes of ROP.1 The insufficient supply of experienced examiners able and willing to screen for ROP necessitates strategies for effective screening by less-experienced examiners. Purpose: 1) to evaluate the ability of non-ROP experts (ophthalmology residents/fellows) to use video indirect ophthalmoscopy (Keeler) to acquire retinal images, and 2) to determine whether these images can be accurately graded for ROP. Methods: We reviewed all videos (with visible optic nerves) acquired by fellows/residents during ROP examinations (7/2013-6/2014). Still images (≤3) captured from each video examination were presented to one junior and one senior attending, masked to all clinical data, who graded them for quality and normal/pre-plus/plus disease. Grades were then compared to clinical examination results (as reference standard). Results: 258 images (107 infants) were presented to the graders; 248/258(96%) were considered good or fair quality by the senior grader. The junior and senior grader had 71% vs. 88% agreement with the clinical exam, respectively. Of those infants with plus disease on clinical examination, the senior vs. junior grader had a sensitivity of grading pre-plus or plus disease of 100% vs. 90% and specificity of 65% vs. 89%, respectively. Discussion: Trainees can obtain high quality retinal images using video indirect ophthalmoscopy of infants requiring ROP screening, which can be graded with high sensitivity to detect plus disease. Conclusion: Less-experienced examiners may play an integral role in future ROP screening guidelines. References: 1.

Quantifying and Qualifying the Use of Topical Anesthetics in Retinopathy of Prematurity Examinations, a Survey Blake D Forcina MD Dean J Bonsall MD, MS, FACS, FACP West Virginia University Morgantown, WV Introduction: Use of topical anesthetic eye drops during retinopathy of prematurity examinations is a common practice, but many ophthalmologists believe it is unnecessary. No data exists to quantify the practice of topical anesthetic use or physicians’ reasons for using or not using anesthetics. Methods: IRB approval was obtained. An online survey was distributed to all active United States and international members of AAPOS. Results: Two hundred and thirty-eight responses were collected. Of the 225 respondents who are active members and screen for ROP, 185 (82.2%) use topical anesthetics, and 40 (17.8%) do not. Of those using anesthetics, proparacaine was the most common at 61%, followed by tetracaine at 34%. Common reasons cited in favor of topical anesthetic use were 1) decreased pain from the speculum insertion and overall comfort, 2) habit, practice pattern, or hospital policy, and 3) decreased pain from scleral depression. Reasons for not using anesthetics included 1) no noticeable difference or unnecessary, 2) no speculum use, and 3) equal efficacy of alternative methods of soothing. Discussion: Although topical anesthetic use during ROP examinations is common, it is far from universal practice. While some believe it decreases ocular pain and its sequelae, others hold that alternative methods are equally effective or that speculum use is unnecessary. Conclusion: This survey is the first of its kind to quantify and qualify use of topical anesthetics during ROP examinations and will guide further research of anesthetic use in ROP screening and development of preferred practice patterns. 123 Electronic Poster 66 Electronic Poster 67 Program for prevention on blindness in Peru: an update Luz J Gordillo MD Ana M Villanueva MD Luz Dodobara MD Arminda Gil Graham E Quinn MD Instituto Damos Vision Avenida Brasil 1129 Lima 11 - Peru Introduction: Retinopathy of prematurity is a common cause of blindness in countries with rapidly developing systems of neonatal care. At present, detection and treatment programs are not widely available in many regions of middle and low income countries. Purpose: Determine the effect of an evidence-based approach to decreasing ROP blindness in Peru by workshops emphasizing neonatal care, especially oxygen administration Methods: Identify where ROP blind babies had been cared for. Concentrating on those teaching hospitals with >1000 births/year, we assessed conditions of oxygen delivery in the neonatal service. We provided interventional workshops, attended by all NICU personnel, offering training and equipment designed to improve neonatal care. A training program for ophthalmologists in detection and treatment of ROP was also provided. Since 2007, 24 NICUs in Lima (2007-July 2013) and 15 NICUs outside Lima (Jan 2012 to present) have participated Results: Only 8 NICUs had sufficient pre-workshop data to assess efficacy, but in those NICUs there are more babies being screened. In 4 of the NICUs, before and after the intervention data were available for treatment. In these, 28 infants were treated among 260 examined before intervention (11%) and 21 of 397 (5%) were treated after intervention (P <0.01), suggesting decreasing severity of ROP associated with the intervention. At present, no new ROP blind children have been found from those NICUs that have participated in the project. Discussion: These results show a positive effect from training of NICU personnel in systems with scarce resources. Conclusion: Though time intensive, intervention workshops to improve neonatal care can reduce the burden of ROP blindness in a country.

However, little is known about the accommodation in individuals treated with IVB or laser. This study is to compare accommodative lag in infants treated with bevacizumab and infants treated with laser ablation. Methods: Infants treated with IVB (N=9; gestational age (GA)=24.2±1.3WK) and with laser ablation (N=11, GA=24.4±1.3WK) were enrolled. Infants treated with IVB had severe zone 1 ROP or posterior zone 2 disease. Between 9 and 24 months, cycloplegic refraction and Teller cards visual acuity were measured; accommodative lag was measured with “monocular estimation method” retinoscopy in binocular viewing a near target at a 50cm distance. Results from the right eye were reported. Results: Spherical equivalent is -0.11±2.63D in the IVB group and 1.20±2.54D in the laser group (P=0.55). Accommodative lag was 0.34±0.47D in the IVB group and 0.69±0.63D in the laser group (P=0.42). Visual acuity was 1.05±0.19logMAR in the IVB group and 0.81±0.22logMAR, in the laser group (P=0.20). The correlation coefficient of accommodative lag and spherical equivalent is 0.81 (P=0.001), suggesting accommodative lag are highly correlated with uncorrected refractive error. Discussion: In this pilot study, although patients in the IVB group often had more severe ROP than in the laser group, our results are promising. Conclusion: There is no significant difference in refraction, visual acuity and accommodation between IVB and laser groups. With the increasing use of IVB, further study with a larger sample is required to understand its effect on refractive development. 124 Severe Retinopathy of Prematurity (ROP) is associated with hypocarbia in ventilated preterm infants Hana Leiba MD Pesah Melnik MD Tali Bdolach Eric Shinwell MD Kaplan Medical Center, Rehovot Israel Electronic Poster 69 Introduction: Retinopathy of Prematurity (ROP) is a leading cause of blindness in children. While excessive Oxygen administration has been implicated in the pathogenesis, the potential role of high or low levels of CO2, a highly vasoactive compound, is unclear. Mechanical ventilation may contribute to both hypercarbia (vasodilatation) and hypocarbia (vasoconstriction). We report a case-control study of the relationship between CO2 levels during the first 3 days of life in ventilated preterm infants and the development of ROP. Methods: The study included ventilated infants born at less than 34 weeks gestational age (GA) at Kaplan Medical Center, Rehovot during 2010-2013. 300 infants met criteria and of these 15 developed ROP of all grades. 16 healthy birth weight and GA-matched controls were identified. The first 72 hours of life were split into18 epochs of 4 hours and in each hypercarbia was defined as above 50 or above 60 and hypocarbia as less than 30 or 35. ROP was assessed as all grades and also as mild (Grades 1-2) and severe (Grades 3+). Results: No difference was found in the occurrence of both hypercarbia and hypocarbia between the ROP and non-ROP groups. However, hypocarbia below 30 mmHg was found in 71% (5/7) infants with severe ROP and in no infants with mild ROP and 19% (3/16) non-ROP infants (p=0.005). Similarly, hypocarbia below 35 was more common in the severe ROP group (86%) vs. 13% in mild ROP and 50% in the non-ROP group (p=0.021). Discussion: Hypocarbia is a risk factor for severe ROP in ventilated preterm infants and should be avoided whenever possible. Conclusion: Hypocarbia is a risk factor for severe ROP in ventilated preterm infants and should be avoided whenever possible. This finding should be confirmed in a larger study. Babies at Risk for Retinopathy of Prematurity in Ghana Akosua A Nti M.D.,1 Vera A Essuman MB.ChB., F.W.A.C.S,2 Christabel Enweronu-Laryea M.R.C.P.C.H., F.G.C.P., 2 Asiedua Ofori-Darko MB.ChB., 2 Graham E Quinn M.D., M.S.C.E. 1 1 Children’s Hospital of Philadelphia, Philadelphia, USA 2 Korle Bu Teaching Hospital, University of Ghana, Accra, Ghana Introduction: Developing Retinopathy of Prematurity (ROP) detection and treatment programs in a region with emerging expertise in care of premature infants is a complex and multifaceted task. We sought to determine the need for such a program in Accra, Ghana. Methods: We undertook a retrospective survey of neonatal care and infants born from 6/2011 to 12/2013 in a single neonatal intensive care unit (NICU) in Korle Bu Teaching Hospital in Accra, Ghana. We collected birth weight (BW), gestational age (GA), survival to discharge, oxygen treatment, and pulse oximeter monitoring status for neonates. Results: The records of 647 premature infants with a GA </= 34 weeks and BW </= 1800g were available for review. Of these, 88% survived to discharge. Mean BW= 1612g (+/- 439g), and GA= 33.4 weeks (+/-2.9 weeks). Of the 37 infants with GA </= 28 weeks, and 63 babies with GA >28-30 weeks, 51% and 68%, respectively, survived to discharge. Among the 62 infants with BW </= 1000g, 45% survived to discharge. Fifty-one percent of infants received oxygen therapy, however only 22% were on pulse oximeter. The nurse to patient ratio in the NICU was 1: 15. Discussion: There are infants at risk of developing ROP in this NICU. Thirteen percent of the infants reviewed fell within the US screening criteria, and 49% fell within the criteria established in Brazil.1-2 Conclusion: There is an urgent need for an ROP screening program in Ghana. Next steps include presenting these data to administrators/Ministry of Health, and a survey of blind schools for ROP blind children in Ghana. References: 1.

While laser photocoagulation remains the ‘gold standard’ treatment, ablative therapy leads to permanent loss of peripheral retinal tissue, may require general anesthesia, is problematic in posterior disease, and may result in greater amounts of myopia later in life. The use of biologic therapies, including bevacizumab, is an evolving treatment paradigm which has short term effectiveness, but has not been systematically studied. Methods: We retrospectively analyzed short- and intermediate-term clinical outcomes for infants treated with either 0.5mg or 0.625mg of intravitreal bevacizumab between February 2011 and August 2014. Outcome measures include recurrence of disease, need for additional procedures, refractive error, and ocular alignment. These data were analyzed both in aggregate as well as via random selection to control for correlation effect. Results: We report clinical outcomes for 27 preterm infants representing 48 eyes treated with intravitreal bevacizumab for vision threatening ROP with follow-up ranging from 3 months to 3.5 years. We identified 13 eyes treated with 0.5mg and 35 eyes treated with 0.625 mg of bevacizumab. There was no statistically significant difference between the gestational age, birth weight, or stage of ROP at treatment between the two groups. When taken in aggregate, we found a 15% (odds ratio 0.2149 95% CI 0.0390 to 1.1848) recurrence rate in those treated with 0.5mg of bevacizumab vs a 9% (odds ratio of 0.1315; 95% CI 0.0264 to 0.6543) rate of recurrence in the 0.625 mg treatment group. Using random eye selection analysis, the 0.5 mg treatment group demonstrated a 12.5% recurrence rate; the 0.625 mg group demonstrated a 5% recurrence rate. |Recurrence in the 0.625mg treatment group occurred at 4.5 weeks post-treatment on average and 14 weeks post-treatment in the 0.5mg treatment group. One-third of treated eyes (16 of 48) demonstrated anatomically full vascularization without evidence of functional impairment by indirect ophthalmoscopy. Laser photocoagulation was performed in the 4 eyes demonstrating recurrent disease; infants not displaying recurrent disease required no additional ocular procedures. The remaining 27 eyes demonstrated stable regression of ROP. When analyzed in aggregate, the average spherical equivalent was -0.98 D. There was no statistically significant difference in refractive outcome between the two treatment groups. Two patients demonstrated a small angle esotropia not requiring surgical intervention; no others displayed strabismus. Discussion: Short and intermediate-term clinical outcomes after treatment of ROP with intravitreal bevacizumab are not well understood. Further, the optimum bevacizumab dose has not been determined. We demonstrate a slightly increased rate of recurrence in the 0.5 mg treatement group; however, no statistical difference was found between groups. Importantly, when taken in aggregate, our data show that a significant proportion of bevacizumab treated eyes, regardless of dose, achieved full vascularization, and no cases of late recurrence were observed in infants followed as long as 3.5 years. All patients showed appropriate visual behavior and no more than minimal myopia. Conclusion: 0.625mg or 0.5 mg of intravitreal bevacizumab are effective for treatment of vision-threatening ROP and appear to produce good intermediate-term visual outcomes. Recurrence of ROP, though uncommon, occurred as late as 15 weeks post-treatment and timing may correlate with bevacizumab dose. References: 1. Blair M and Shapiro MJ. Bevacizumab for ROP.

Lindner, M.S., David Antonetti, Ph.D., Steven Abcouwer, Ph.D. Univerity of Michigan Kellogg Eye Center Ann Arbor, MI Introduction: Retinal ischemia is common in retinopathy of prematurity and diabetic retinopathy. The retinal ischemia-reperfusion (IR) model exhibits neurodegeneration, blood-retina-barrier (BRB) disruption and neuroinflammation, coinciding with increased CCL2 chemokine expression. CCL2 is known to alter endothelial tight junction function, attract monocytes, and modulate microglial activation in the central nervous system. This study examined leukocyte infiltration and the role of CCL2 in retinal microglia reaction to IR injury. Methods: Immunofluorescence (IF) analysis of flat-mounted retinas was used to identify microglia, leukocytes, blood vessels, and endothelial tight junctions. The effects of IR injury on microglia numbers and soma volume increase (a measure of activation) were compared in wild-type (Ccl2+/+) and Ccl2 knock-out (Ccl2-/-) mice. Results: After IR, CD45+ leukocytes appeared in regions with disrupted vascular tight junctions suggesting a possible route of extravasation. Iba1+ microglia exhibited decreased ramification and increased soma size after IR. The number and soma size of microglia were increased after IR in both Ccl2-/- and Ccl2+/+ retinas, with a significantly larger increase in soma size for Ccl2-/- compared to Ccl2+/+ retinas. Discussion: Neroinflammation following retinal IR injury included microglial activation, disruption of endothelial tight junctions, and leukocyte infiltration. Future studies using bone marrow chimeras may help elucidate whether additional Iba1+ cells are derived from resident microglia or from infiltrating monocytes. Conclusion: CCL2 appears to modulate the activation of microglia after IR. 126 Facilitated versus self-guided training for grading of retinal images for ROP Nikolas N Raufi, BA; Caleb K Morris, MD; Sharon F Freedman, MD; David K Wallace, MD, MPH; Sasapin G Prakalapakorn, MD, MPH Duke University Eye Center 2351 Erwin Rd. Durham, NC 27705 Electronic Poster 73 Introduction: Retinopathy of prematurity (ROP) remains an important cause of preventable blindness; screening barriers necessitate novel approaches. While trained non-physicians can accurately grade wide-field retinal images for ROP,i effective training protocols have not been determined. This study compares the effectiveness of facilitated versus self-guided training for grading retinal images for ROP. Methods: Thirty undergraduate and graduate students were trained to analyze narrow-field (i.e. from indirect ophthalmoscopy) still retinal imagesii for the presence of pre-plus or plus disease. Students were randomized into one of two training protocols. Both utilized identical electronic slideshows, but one was guided by an in-person facilitator, and the other was self-guided. After completing their respective training, students showing proficiency in grading pre-plus and plus disease graded a 107-retinal-image screening scenario. Accuracy of grading for ROP was compared to a reference standard (i.e. clinical examination). Results: 80% (24/30) of trained students (89% in the facilitated versus 76% in the self-guided group, p=0.6) qualified to grade the ROP screening scenario. Median accuracy for grading normal, pre-plus or plus disease was 71% (71% in the facilitated vs. 70% in the self-guided group). When considering the designation of plus or pre-plus disease by graders as a screening test for detecting plus disease (confirmed on clinical exam), the median sensitivity of both groups was 97% and the median specificity 63%. Discussion: Both facilitated- and self-guided teaching protocols yielded similar performance in ROP image grading. Conclusion: Self-guided training protocols may be adequate to train non-ophthalmologists to appreciate retinal blood vessel changes and detect plus disease with high sensitivity. References: i.

Evaluating the Clinical Benefit of Earlier Retinopathy of Prematurity Screening Dipal P Shah, MD Majida Gaffar, MD North Shore - Long Island Jewish Health Center Great Neck, NY Introduction: To determine if screening of infants born between 22-24 weeks gestational age (GA) prior to 31 weeks is beneficial to the neonate in diagnosing and treating their retinopathy.(1) Methods: Retrospective chart review of 275 infants (550 eyes) screened between July 2013 - August 2014 at a XXX NICU was conducted. Infants included were 22-24 weeks GA. Outcome measures were presence of ROP prior to 31 weeks, ROP at initial examination, and treatment initiated prior to 31 weeks. Results: Twenty patients met criteria; 1 died prior to first examination. Average GA 23.65 weeks (SD=0.49); average BW 692.45 grams. Average age on initial examination 29.95 weeks (SD=1.22). Ten babies screened prior to 31 weeks GA, 3 had ROP (30%) on initial examination. Nine subjects first evaluated at 31 weeks, 6 (66%) had ROP on initial presentation. No infants had type I ROP prior to 31 weeks. Nine infants required treatment (47%) with average GA 34.9 weeks. Average number of examinations prior to 31 weeks 0.95 (range=0-3). Discussion: ROP examinations on neonates can be psychologically harmful for both infant and parents. Although rare, dilating drops can cause episodes of apnea and bradycardia in neonates, further warranting the need to elucidate the efficacy of earlier ROP exams.(2) Conclusion: Although more data is needed, based on this small subset of infants, we can conclude that starting the screening process at 31 weeks may be adequate in identifying at risk infants.

Methods: A retrospective chart review was done for all infants with minimum of 72 weeks of postmenstrual age at last follow up. Main outcomes included timing of involution of type 1 ROP for the first 12 weeks post treatment and structural outcomes at last follow up. Data was collected on demographics, retinal examination results at each visit and development of recurrence and/or retinal detachment (RD). Findings are described in cumulative frequency tables. Results: Seventeen infants (28 eyes) were included. The average follow up period post treatment was 22 ±11.25 months (range 8.9-55.1). Regression of plus disease was seen in 71%, 88%, and 100% by days 3, 5, and 8 cumulatively. Regression of both stage 3 and plus/preplus ROP was observed cumulatively in 29%, 82%, 88%, and 100% by weeks 1, 2, 3, and 4 post treatment. None developed a recurrence or RD at last follow up. Discussion: Regression of plus disease occurred earlier than regression of stage 3 and was seen in all by eight days. Regression of stage 3 was observed in 100% of eyes by week four. We did not observe any unfavorable structural outcomes at last follow up. Conclusion: Based on this data, routine laser treatment soon after bevacizumab injection may not be indicated. Our experience suggests that disease recurrence and retinal detachment are not common. None of our patients required further laser treatment. Electronic Poster 76 ROPtool Analysis of Images from a Non-contact Handheld Fundus Camera Laura A Vickers Sharon F Freedman David K Wallace S. Grace Prakalapakorn Duke University Eye Center Durham, North Carolina, 27710 Introduction: While the diagnosis of plus disease in retinopathy of prematurity (ROP) largely determines the need for treatment, it is subjective and prone to error. ROPtool is a semi-automated computer program that quantifies vascular tortuosity and dilation. Pictor is an FDA-approved, non-contact, handheld fundus camera that can simultaneously take a color and red-free digital retinal photograph. We evaluated ROPtool’s ability to analyze digital retinal images of prematurely born infants taken with Pictor. Methods: We analyzed Pictor images that were previously acquired coinciding with routine ROP screening of infants.[1] For this study, we included only images that were considered to have fair or good quality and four quadrants that could be graded by experts. We used ROPtool to analyze a color and corresponding red-free image from one eye of each infant. An image was ‘traceable’ if ROPtool could trace 2 major blood vessels >/=1 disc diameter from the optic nerve in each of the 4 quadrants. We evaluated ROPtool’s ability to analyze Pictor images and generated ROC curves to assess ROPtool’s accuracy relative to bedside clinical examination. Results: Of the 48 infants with Pictor images, 40(83%) fulfilled inclusion criteria. Of these, ROPtool could trace 35(88%) color and 37(92%) red-free images. Areas under ROC curves for the diagnosis of plus disease were 0.83 for color versus 0.89 for red-free images (p=0.2). Discussion: ROPtool can trace most fair or good quality Pictor fundus images and can diagnose plus disease with very good accuracy. Conclusion: ROPtool analysis of Pictor images shows promise for ROP screening. References: [1] Prakalapakorn SG, Wallace DK, Freedman SF.

Methods: In 2090 premature infants (11 centers), multiple logistic regression analysis (MLRA) of predictive variables for an outcome of TROP included ADL during days 61-90 after conception (ADL61-90). Results: Increasing birth weight & gestational age and black race were associated with a lower, while male gender was associated with a higher, likelihood of TROP. Multiple birth status was not predictive of outcome. While ADL61-90 was not significantly associated with TROP in the overall population (p=0.104), subgroup analysis for 530 black infants showed that each additional hour of ADL61-90 (range: 8.98 to 15.4 h) was associated with a 31.5 % lower likelihood of developing TROP (Odds Ratio: 0.685, p = 0.003). The addition of WINROP alarm status, a marker of “illness severity”, to the MLRA did not eliminate ADL61-90 as a significant predictor. Discussion: The association of ADL with TROP occurred only in black infants and may be due to greater attenuation of light to a critical threshold of response by the mother’s darker skin pigment and/or involvement of a different pathway for light-induced vascular development. Current treatment at the less severe type 1 prethreshold ROP may have masked the previously reported association of ADL with more severe ROP, i.e. classic threshold, in a different cohort of infants. Conclusion: There may be a role for light therapy in early gestation to reduce the risk of TROP among black premature infants. References: 1.

The spectrum of diplopia management in ocular motility disorders Shauna E Berry DO Matthew D Kay MD Garima Lal MD Kathryn E Ireland DO Clint W Kellogg DO Hang M Tran MPH Larkin Community Hospital Miami, FL Introduction: We retrospectively evaluated the percentage of patients with an ocular motility disorder that opted for strabismus surgery versus prismatic correction. Methods: All new patients billed between March- June 2013 with a 378 ICD9 code were selected for chart review. We assessed whether the diplopia was managed with observation, occlusion, prism glasses, or strabismus surgery. Patients with the diagnosis of ocular myasthenia gravis were excluded. Other factors taken into consideration were patient satisfaction with prism glasses, previous strabismus surgery, if surgery was discussed as an option, and if pathology was evident on radiologic or laboratory studies. Results: 122 patients with a total of 135 independent diplopic events were reviewed in regards to management. Of these diplopic events, surgery was discussed with 15 % of patients of which 47% selected surgical management. Prism glasses were prescribed to 51.9% of patients which yielded 67% patient satisfaction with prismatic correction alone. Discussion: A large volume of patients present to neuro-ophthalmology practices with ocular motility disorders. In this setting it is important that the neuro-ophthalmologist and strabismologist work together to manage the diplopia. Strabismus surgery was discussed as an option with the patient when deemed appropriate, typically after stabilization of the motility dysfunction. Patients included in this study presented with a cranial nerve palsy, divergence insufficiency, thyroid eye disease, convergence insufficiency, hypertropias, exotropias, and esotropias. Spontaneous resolution occurred in approximately 25% of cases, generally in the setting of a microvascular nerve palsy. Conclusion: The majority of patients presenting with diplopia were satisfied with conservative non-surgical management. 129 Electronic Poster 78 Electronic Poster 79 Acquired Inverse Duane Retraction Syndrome Secondary to Medial Rectus Muscle Cysticercosis Venkateshwar Bhoompally MD Ramesh Kekunnaya DO, FRCS Jyoti Matalia DNB Shreya Eye Care Center Hyderabad India Introduction: Inverse Duane retraction syndrome is an uncommon condition with reverse clinical features of classic Duane syndrome. It is most often seen due to entrapment of medial rectus muscle in the medial orbital wall after trauma. Purpose - To report 2 cases of acquired inverse Duane retraction syndrome caused by infestation of the medial rectus muscle by cysticercosis cellulosae. Methods: Two cases presented with 5-10 days history of pain, redness with diplopia. Clinical examination of ocular motility established a diagnosis of inverse Duane retraction syndrome.Imaging(CT/MRI) and ultrasonography of the orbit established the diagnosis of cysticercosis of the medial rectus muscle. Oral albendazole (15 mg/kg) and corticosteroid (1mg/kg) were given for a month and followed up for one year Results: Clinical recovery with improvement of ocular motility and regression of imaging features was noted at the end of treatment Discussion: The treatment of cysticercosis of extraocular muscles has shifted from surgical to medical therapy following successful results using oral albendazole.Oral corticosteroids are recommended along with cysticidal drugs to control the inflammation produced from the dying cyst, thereby preventing chronic fibrosis in the involved extraocular muscle. Conclusion: Acquired inverse Duane retraction syndrome secondary to medial rectus muscle cysticercosis is a new entity.

Michael Siatkowski MD Bradley K Farris MD Dean McGee Eye Institute Oklahoma City, Oklahoma Introduction: Accurate measurement of strabismus is vital to diagnosis and treatment. We hypothesized that subjective measurement techniques would measure larger deviations than objective ones. Methods: Adults with strabismus, visual acuity > 20/40 in each eye and normal retinal correspondence had deviations measured at distance and near using alternate prism cover (ACPT) and red glass tests (RGT). Results: Forty-two subjects have been enrolled to date. Median data points were compared using the signed rank test. McNemar’s test was used to compare categorical data points. The RGT tended to measure a larger distance horizontal deviation (6 vs 4 PD, p=0.03), and detected a vertical deviation more frequently at both distance (5 vs 0, p=0.025) and near (9 vs 1, p=0.011). Of 158 measurement sets, 136 (86%) were within 4 PD of each other. In 5% of cases, the discrepancy was > 10 PD. Discussion: While in the majority of cases both tests measured similar deviations, the RGT was more likely to measure a larger distance horizontal deviation and to detect vertical deviations. Deviation discrepancy of > 10 PD occurred rarely and there was no obvious trend for either technique to measure a larger deviation in these cases. Conclusion: In patients with NRC, both subjective and objective measurement techniques generally yield similar results. The differences we noted were most likely to be clinically important when prescribing small amounts of vertical prism. Inter-test discrepancy that would likely influence surgical planning occurred in only 5% of cases, with neither technique being clearly superior. 130 Correction of binocular diplopia with novel contact lens technology Tara L Bragg CO Christine Sindt OD University of Iowa Department of Ophthalmology & Visual Sciences Iowa City, Iowa Electronic Poster 81 Introduction: Small angle strabismic deviations with binocular diplopia can be difficult to treat satisfactorily in contact lens wearers who are often not happy wearing glasses. This is a case study examining the clinical success of new prismatic contact lens technology in the correction of binocular diplopia. Methods: We present a 48 year old woman with a history of keratoconus, high myopia and a 4 prism diopter comitant right hypertropia with binocular diplopia. Her refractive needs had previously been met by scleral contact lens wear; however she needed the addition of spectacles with vertical prismatic correction for the maintenance of binocular single vision. She was fit with an EyePrintPROTM custom scleral device, made from an impression of the ocular surface, in each eye for correction of her irregular astigmatism. 3.5 prism diopters base up prism was incorporated into the device design for the left eye. Results: Wearing these contact lenses, her acuity is 20/20 in each eye and she reports no vertical diplopia. She measures 1 to 2 prism diopters of right hyperphoria in primary. Discussion: To our knowledge, stable base up prismatic correction has not been reported in a contact lens device. It is the manufacturers’ hope to incorporate up to 8 prism diopters of optical prism per lens in any direction; approximately equivalent to the maximum amount of prism that can be comfortably ground into spectacle lenses. Conclusion: This case study introduces and examines the successful use of new custom scleral contact lens technology for stable base up prismatic correction of vertical binocular diplopia. Quality of Life in Strabismus Melinda Chang MD Federico Velez MD Joseph Demer MD, PhD Sherwin Isenberg MD Anne Coleman MD, PhD Stacy Pineles MD Jules Stein Eye Institute, University of California, Los Angeles Los Angeles, CA Introduction: Strabismus can detrimentally influence quality of life by affecting both vision and appearance. Little is known about how quality of life in strabismus patients compares to quality of life in patients with other ocular diseases. We aim to assess the relative impact of strabismus on quality of life. Methods: Forty-two adults over the age of 50 with strabismus were recruited from four pediatric ophthalmology clinics at a single institution. All subjects completed the 25-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25). NEI VFQ-25 subscale score means and standard deviations were compared between strabismus patients and patients with other ocular diseases, including diabetic retinopathy, age-related macular degeneration (AMD), glaucoma, cataract, cytomegalovirus (CMV) retinitis, and low vision, as reported in the National Eye Institute Visual Functioning Questionnaire field test study. Results: Patients with strabismus performed the same or worse on nearly all vision-related subscales compared to patients with diabetic retinopathy, age-related macular degeneration, glaucoma, cataract, and CMV retinitis. Additionally, strabismic patients reported significantly worse ocular pain than patients with all other ocular diseases studied (p < 0.0001 in all cases). Discussion: Strabismus may have a greater impact on quality of life than other common ocular diseases. Both functional and psychosocial factors may contribute to diminished quality of life in strabismic patients. Conclusion: Physicians treating patients with strabismus should be aware of the quality of life issues unique to these patients and address them accordingly. References: 1.

Methods: Surface coil MRI was obtained at 312 micron resolution in quasi-coronal planes in 13 subjects (25 orbits) in target-controlled central gaze, plus a wide range of supraduction and infraduction. Ductions were quantified by change in position of the globe-optic nerve junction. EOM cross-sections were manually outlined in contigous 2-mm thick image planes spanning the orbit, then areas, partial volumes, and locations of peak cross sections were computed. Results: All single plane and posterior multi-plane measures correlated significantly with degrees of duction for all cyclovertical EOMs (p < 0.01). For the inferior rectus (IR) and superior oblique (SO), anterior multi-plane measures had a significant negative correlation. The best measure observable in a single plane was the percentage change in maximum cross-section (R2 = 0.76 for superior rectus (SR), 0.53 for IR, and 0.46 for SO). The best measure observable from multiple planes was the percentage change in partial volumes (PPV) in the region 8-14 mm posterior to the globe-optic nerve junction (R2 = 0.84 for SR, 0.90 for IR, 0.56 for SO). Discussion: Like horizontal EOMs, the percentage change in PPV correlates best with degrees of vertical duction. Conclusion: Change in cyclovertical EOM morphology correlates well with degrees of duction, providing a reliable estimate of contractility useful for quantifying over- and underaction.

Electronic Poster 84 ‘Knobby Eye Syndrome:’ Irregular Posterior Staphyloma As A Factor Complicating Strabismus In High Myopia Joseph L Demer MD, PhD Stein Eye Institute and Department of Neurology, University of California, Los Angeles Los Angeles, California Introduction: Traditional concepts of strabismus assume a spherical globe. This study employed magnetic resonance imaging (MRI) to demonstrate complex effects of irregular posterior staphylomata in axial high myopes with strabismus. Methods: High resolution (2 mm planes, 312 micron resolution), surface coil axial MRI was obtained in central gaze in 18 highly myopic subjects with strabismus. Scans were repeated in dextro- and levoversion in most subjects. Images were analyzed for scleral shape and deflection of muscle paths. Results: While myopic globes were generally spherical in 6 subjects, one or both globes of the other 12 subjects exhibited prominent irregular nasal posterior, temporal posterior, nasal and temporal posterior, or equatorial (1 case) staphylomata. These scleral ectasias were positioned to contact and elongate the paths of the horizontal rectus muscles in some gaze positions. Axial length averaged 30.3±3.3 (SD) mm for eyes with irregular staphylomata, not significantly different from 28.2±0.8 mm in spherical eyes (P>0.15). While subjects with irregular staphylomata were older at 57±11 years than spherical eye subjects at 24±8 years (P<0.0005), other clinical features were similar. Discussion: Irregular equatorial or posterior staphylomata are common in strabismic axial high myopes. Staphylomata act like ‘cams’ affixed to the normally spherical globe; thus staphylomata have no mechanical effect until they ecentrically rotate against muscles. After rotational contact, staphylomata would add tension to the muscle that increases non-linearly with further duction. This phenomenon, detectable only by imaging, might be confused with myopathic or neurogenic pathology. Conclusion: Concepts of strabismus in axial high myopes should be expanded to include nonlinear changes in muscle tension produced by irregular posterior staphylomata; imaging may be clinically informative about this “knobby eye syndrome.” 132 Dissociated ocular deviations in adults Sneh S Dhannawat MBBS David A Leske MS Jonathan M Holmes BM, BCh Mayo Clinic Rochester, Minnesota Electronic Poster 85 Introduction: To describe clinical characteristics, symptoms and quality of life in adults with dissociated vertical deviation (DVD) and dissociated horizontal deviation (DHD). Methods: We retrospectively identified adults with dissociated ocular deviations, defined as a difference in deviation between fixing right and fixing left eyes (violating Hering’s law) of >2pd vertically (DVD) and/ or >5pd horizontally (DHD). We used a standardized 10 seconds prism under cover test. We excluded paretic and restrictive strabismus. All patients completed the Adult Strabismus-20 (AS-20) HRQOL questionnaire, the diplopia questionnaire, and rated strain on a 5-point frequency scale. Results: Of 35 adults, all had DVD and 6 also had DHD. Associated current distance horizontal deviations were esotropia (17) and exotropia (18). 14 (40%) were microtropic at distance and near. 31 (89%) patients had childhood strabismus surgery. Regarding original strabismus, 28 (80%) had infantile ET, 2 (6%) had infantile XT, 1 (3%) had childhood ET, and 4 (11%) had childhood XT. 20 (57%) rated strain as often or sometimes. Subnormal AS-20 scores were found in 25 (71%) in self-perception, 25 (71%) in interactions, 21 (60%) in reading function, and 26 (74%) in general function. 5 (14%) reported more than rare diplopia in distance straight ahead and 4 (11%) reported more than rare diplopia for reading. Discussion: DVD and DHD in adults may be associated with strain, diplopia, and HRQOL concerns. Conclusion: DVD and DHD may be symptomatic in adults and treatment should be considered. Childhood intermittent exotropia from a different angle: does severity affect quality of life? Shin B Lim Miss Wan L Wong Miss Inez B Wong FRCSEd(Ophth) National University Hospital 1E Kent Ridge Road, NUHS Tower Block 7, Singapore 119288, Republic of Singapore Introduction: Few studies have explored the relationship between heath-related quality of life (HRQOL) and clinical severity of childhood intermittent exotropia (IXT). Methods: Sixty-eight consecutive children aged 5-17 with IXT attending the pediatric eye clinic were recruited, together with 1 accompanying parent. HRQOL was measured using the intermittent exotropia questionnaire (IXTQ)[1]. Clinical measures of IXT (angle of deviation, control, stereoacuity and visual acuity) were correlated with IXTQ scores using Student’s t-test and Pearson’s correlation coefficient. Results: 62 children and 68 parents were included in the analysis. There was no correlation between child HRQOL and clinical measures of IXT. Poorer parent HRQOL was correlated with poorer distance control (surgery subscale, r = -0.24 p = 0.049), poorer near control (surgery subscale, r = -0.30, p = 0.013), poorer office control (mean, r = -0.24, p = 0.047; psychological subscale, r = -0.27, p = 0.025; surgery subscale, r = -0.28, p = 0.020) and larger angle of deviation (psychological subscale, r = -0.30, p = 0.013). Poorer proxy HRQOL was correlated with poorer home control (r = -0.28, p = 0.022) and larger angle of deviation (r = 0.33, p = 0.0061). Discussion: It is difficult to predict child HRQOL based on clinical measurements. However, parent HRQOL is likely to be worse if the child’s IXT is more severe. Conclusion: Parents’ views have a major influence on treatment decisions in this pediatric condition. HRQOL can be routinely assessed in clinic to ensure the views of both children and parents are represented, so as to tailor management appropriately. References: 1.

We describe the first documented case of excyclotorsion causing diplopia following toric IOL implantation. Methods: Retrospective case note review and literature search. Results: A 78 year-old woman presented with one week’s history of diplopia. She had undergone bilateral cataract surgery, the right with a toric IOL. On examination, visual acuity was 20/40 OD and 20/30 OS. She exhibited right hyperphoria (3 ^ R/L), exophoria (15 ^ BI) and excyclotorsion measuring 5° in primary gaze, worsening to 8° in downgaze. Anterior segment examination demonstrated rotation of the right toric IOL with its axis at 85° - 20° away from the intended position. The patient underwent urgent repositioning of the toric IOL. Post-operatively, her visual acuity improved to 20/20, excyclotorsion reduced to 2° in primary gaze and hyperphoria to 2 ^ R/L, which she could fuse. At 3-month follow-up, the patient was asymptomatic. Discussion: Post-operative rotation of toric IOLs has clinically significant consequences. Rayner T-flex IOLs (as used in this case) have a reported 3.4-5.0° mean rotational stability and 9-21% of these patients have >10° post-operative misalignment (Entabi et al 2011, Stewart & McAlister 2010). In this case, toric IOL implantation exacerbated a pre-existing asymptomatic torsion, resulting in visual decompensation and subsequent diplopia. Conclusion: The case described is a rare complication following toric IOL implantation and ophthalmologists need to examine for torsion carefully and be aware of the possibility of inducing torsional symptoms following surgery.

Electronic Poster 88 Stereoacuity in Children with Accommodative Esotropia versus Partially Accommodative Esotropia Brian Mohney Nancy N Diehl Mayo Clinic Rochester, Minnesota Introduction: High grade stereoacuity is an essential characteristic of ocular alignment and long-term motor stability. The purpose of this study was to assess population-based stereoacuity outcomes in children with fully accommodative esotropia compared to partially accommodative esotropia. Methods: All children (< 19 years) diagnosed with accommodative esotropia in XXX from January 1, 1975 through December 31, 1994, were retrospectively reviewed for their final stereoacuity. Results: A total of 306 children with accommodative esotropia were diagnosed during the study years; 244 (80%) were fully accommodative and 62 (20%) were partially accommodative. After a mean follow-up of 9.8 years, the median final stereoacuity was 100 arc seconds (range, 40-nil) among children with fully accommodative esotropia compared to 800 arc seconds (range, 40-nil) for those with partially accommodative esotropia (p=<0.001). High-grade stereoacuity (> 60 arc seconds) was found in 81/230 (35.2%) of the 244 children with accommodative esotropia compared to 8/58 (13.8%) of 62 with partially accommodative esotropia at final follow-up (p=0.002). Discussion: Children with fully accommodative esotropia are significantly more likely to achieve high-grade stereoacuity than are those with partially accommodative esotropia. Further investigation is warranted to explain these differences and the factors associated with the development of high-grade stereoacuity. Conclusion: In this population-based cohort of 306 children, fully accommodative esotropia was associated with significantly better stereoacuity outcomes compared to those with partially accommodative esotropia. 134 Superior oblique muscle size in Brown syndrome Soh Youn Suh MD Joseph Demer MD,PhD Stein Eye Institute, UCLA Los Angeles, California Introduction: Isometric exercise has been promoted for skeletal muscle growth. The restrictive limitation to supraduction in adduction in Brown syndrome can cause isometric contraction of the superior oblique (SO) muscle that might potentially contribute to muscle hypertrophy. We thus asked if there are size changes in SO muscles in Brown syndrome. Methods: High resolution, quasi-coronal orbital MRI were obtained in 20 patients with Brown syndrome and 59 normal control subjects. Maximum cross-section area of the SO muscle belly in central gaze was determined by digital image analysis in both eyes of patients with Brown syndrome, and compared with controls. Results: Eight congenital and 12 acquired Brown syndrome patients were included. Seventeen patients had unilateral and 3 had bilateral Brown syndrome. Mean maximum SO cross-section area was 16.3 ± 3.8 mm2 in the ipsilesional eye, and 16.6 ± 3.4 mm2 in contralesional eye in unilateral cases, and 17.8 ± 2.2 mm2 in bilateral cases. Differences in SO muscle size between ipsilesional and contralesional eyes were not significant (P=.356). Mean SO cross-section area was 17.8 ± 2.8 mm2 in normal subjects, not significantly different from Brown syndrome (P=.122). Discussion: Isometric SO contraction in attempted supraduction in adduction in Brown syndrome does not produce compensatory change in SO muscle size. This may be because isometric contraction does not induce hypertrophy in extraocular muscles, or because patients compensate by avoiding the problematic gaze position. Conclusion: Despite restriction that requires the unusual situation of isometric contraction, affected SO muscles in Brown syndrome have normal size, reflecting absence of compensatory hypertrophy.

What does convergence insufficiency look like to the strabismologist? Naomie K Warner DO Judith Lavrich MD Barry Wasserman MD Caroline Debenedictis MD Bruce Schnall MD Donnelson Manley MD Kammi Gunton MD Wills Eye Hospital 840 Walnut St, Suite 1210, Philadelphia, PA 19107 Introduction: Convergence insufficiency (CI) is commonly described as the inability to bring both eyes together on a near target. Patients with CI often have symptoms such as headaches, asthenopia, difficulty reading or doing tasks at near, or diplopia. The clinical findings of abnormal near points of convergence, decreased fusional amplitudes and phorias or tropias can help to make a diagnosis, however not all patients will have all findings. Methods: We have conducted a retrospective chart review of over 800 patients with the diagnosis of convergence insufficiency to examine exactly what this disease looks like to the strabismologist on initial diagnosis. We reviewed 260 patient charts to date and collected data on 145 patients. Data was analyzed using positive regression. Results: Our results showed a significant correlation between an older age of diagnosis and manifest refraction, strabismus and symptoms such as diplopia, difficulty focusing and pain. Individuals who are orthophoric were more likely to be diagnosed at a younger age than those who are exotrophic or exophoric. Myopic and emmetropic individuals were also more likely to be diagnosed at an older age. Discussion: The current literature discusses patients who have been diagnosed with convergence insufficiency while not having any of the above findings. Controversy also exists regarding fusional amplitudes, tropias and phorias. Typically CI has manifested as an exotropia greater at near than distance, however in up to 3% of diagnoses there may actually be an esotropia reported. Conclusion: Definitive criteria are needed to better classify convergence insufficiency. 135 Electronic Poster 90 Electronic Poster 91 Extraocular Muscles Abnormalities and Surgical Management of Strabismus Following Melanoma Plaque Brachytherapy Shatha H Alfreihi MD Stacy Pineles MD Tara McCannel M.D. , Ph.D Colin McCannel M.D. Ben Glasgow MD Federico Velez MD UCLA Los Angeles, CA Introduction: Strabismus following plaque brachytherapy for ocular melanoma is a rare complication. Management is complex due to factors affecting the muscles and periocular tissues that may have resulted from the plaque implantation and the radiation exposure. The mechanism of strabismus is not well described. Methods: Patients who developed strabismus following melanoma plaque brachytherapy that underwent strabismus surgery were retrospectively studied. Pre-operative and post-operative orthotropic examination findings, intraoperative and MRI findings were reviewed. Results: A total of 6 patients were included. Preoperatively, 5 patients had a horizontal and vertical deviation in primary gaze, 1 had vertical deviation only, and 2 had excycolotorsion. Mean preoperative horizontal deviation was 22.6 PD, and mean vertical deviation was 10 PD. At final follow-up examination mean horizontal deviation was 4.4 PD and vertical 5.83 PD. In a patient with large exotropia, pathology showed mild myofiibrillar disarry and endomesial fibrosis of the medial rectus muscle, and MRI showed enlarged muscle. Intraoperative photos of another patient showed enlarged muscle. Discussion: Strabismus post plaque brachytherapy for ocular melanoma is associated with a unique form of extraocular muscle fibrosis, thickening and weakening. Antagonist muscle contracture and radiation could also contribute to the etiology. Conclusion: Strabismus following brachytherapy plaque for melanoma is challenging due to incomitance caused by muscle fibrosis and weakness. Ocular motility assessment and Imaging studies may help guide surgical planning. Electronic Poster 92 Successfully Managed Endophthalmitis following Strabismus Surgery in Three Patients Saba T Alniemi MD Sophie J Bakri MD Brian G Mohney MD Mayo Clinic Department of Ophthalmology Rochester, Minnesota, USA Introduction: Endophthalmitis generally results in very poor outcomes. The purpose of this study was to report a series of 3 consecutive patients with severe endophthalmitis following apparently uneventful strabismus surgery in which all 3 returned to their preoperative vision. Methods: The medical records of 3 consecutive cases of post-operative endophthalmitis following strabismus surgery at a single institution were retrospectively reviewed. Results: Three male patients (age 20 months, 6 years, and 57 years) each underwent uneventful bilateral strabismus surgery. Unilateral endophthalmitis with an associated scleral or choroidal abscess adjacent to a recessed muscle was diagnosed a mean of 11 days (range, 3-18 days) following surgery. All 3 were treated with >/= 1 dose of intravitreal antibiotics as well as intravitreal dexamethasone in 2, while one patient required cataract surgery. The vision returned to the preoperative level by 11 weeks in the adult and to normal vision after 18 months of follow-up in the 2 children. Discussion: Traditional treatment of endophthalmitis consists of a vitreal tap and intravitreal antibiotics, often also accompanied by vitrectomy, and subconjunctival, topical, and systemic antibiotics. All 3 of the study cases were treated with intravitreal, topical, and systemic antibiotics at the first suspicion of infection. Intravitreal steroids were utilized in 2 of the patients to decrease ocular inflammation. Conclusion: Endophthalmitis following strabismus surgery is not always associated with poor outcomes. The use of intravitreal dexamethasone in 2 of the study patients, although controversial, may have played an advantageous role in the outcome of these patients. 136 Defining Quality Standards in Primary Convergent Squint SurgeryA Prospective 5 year Audit Electronic Poster 93 Adam C Bates MBChB, FRCOphth Phey Feng Lo MBBS Eye, Ear and Mouth Unit, Maidstone and Tunbridge Wells NHS Trust Maidstone, Kent, United Kingdom Introduction: To measure consistency of the Consultant team’s performance in performing primary convergent squint surgery over 5 years. Methods: Data was collected prospectively on 107 children undergoing unilateral or bilateral convergent squint surgery for primary esotropia over a 5-year period. Age of children ranged from 1 to 13 years old. The target distance angle on prism cover testing was determined pre-operatively and the outcome 3 months post-operatively was compared to the target angle. Results: Validity of surgical dosage tables was confirmed by the average deviation from aim being -0.29 prism dioptres (indicating a slight tendency to undercorrection). The mean absolute deviation as a measure of variability in performance was 6.78 prism dioptres over the 5-year period. To assess a trend in performance the period was split into 4 equal sections and the mean absolute deviation showed a reduction with time. 58.9% of cases were within 5 prism dioptres from the aim whilst 79.4% were within 10 prism dioptres from the aim. Discussion: Most published papers on horizontal strabismus show outcomes of surgery with patients achieving an outcome within 10PD of orthotropia. We believe that an individualised target angle should be determined for each patient based primarily on the probability of a patient obtaining motor with or without sensory control post-operatively and/or the probable long-term tendency to exotropic shift in non-binocular patients. Conclusion: Our results show both consistencies in outcomes over time and continued accuracy of the team’s surgical tables. Instructions to patients and families following strabismus surgery Gad Dotan Hanya M Qureshi Leonard B Nelson Department of Ophthalmology, Tel Aviv Medical Center and Pediatric Ophthalmology and Ocular Genetics, Wills Eye Hospital Tel Aviv, Israel and Philadelphia, PA Introduction: Instructions to patients following strabismus surgery often differ between surgeons, and are usually based on personal experience and prior training. The purpose of this study was to identify common post-operative practice policies. Methods: In April 2012 a 12 question electronic survey was sent to all AAPOS members questioning their instructions to patients undergoing strabismus surgery. The questions specifically addressed patients’ daily activities, such as their resumption of school and work, sports, swimming, normal showering and bathing, and contact lens use. Results: One hundred and two responses were completed. Participation was greater by North-American members (86%) and respondents with more than 10 years of experience (75%). Fifty percent of the respondents advised patients to resume normal showering and bathing 24 hours after surgery. Conversely, respondents recommended that children wait 3-4 days before resuming schoolwork (52%) and at least 2 weeks before playing in a sandbox (47%). Furthermore, respondents indicated that patients should refrain from participating in sports-related activities for at least a week (43%) and should not go swimming for at least 2 weeks (56%). Finally, 47% percent advised their patients not to wear contact lenses for 2 weeks after surgery. Discussion: Overall, the responses indicated a high regard amongst AAPOS members for promoting normal healing and prevention of infection and other post-operative complications. Conclusion: This survey identified that following strabismus surgery, normal showering is commonly resumed after 1 day, schooling after 3-4 days, sports-related activities after 1 week, and sandbox play, swimming, and contact lens wear after 2 weeks. 137 Electronic Poster 94 Electronic Poster 95 Electronic Poster 96 Total Transposition Combined with Resection of Superior and Inferior Rectus Muscles in the Treatment of Complete 6th Cranial Nerve Palsy. Marina A Eisenberg Steven M Archer Monte A Del Monte University of Michigan, Kellogg Eye Center Ann Arbor, Michigan Introduction: Complete 6th cranial nerve palsy results in large angle incomitant esotropia, often with diplopia. Current surgical techniques are often technically difficult and associated with complications. This study compares outcomes of combining small resections of superior and inferior rectus muscles with total transposition adjacent to the lateral rectus insertion to outcomes of Foster-Augmented Transpositions. Methods: Records of patients undergoing transpositions for complete 6th cranial nerve palsies between 1/1/1985 and 8/1/2014 done by MDM and SMA were reviewed. A t-test was employed for statistical analysis. Results: Relative changes in horizontal deviation in primary gaze were not statistically significant between procedures(p=0.2). Nevertheless, horizontal and vertical post-operative deviations were smaller (p=0.016 and p=0.006) after Foster-Augmented Transpositions. Post-operative abduction improvement measured 1.9 with Foster-Augmented Transpositions and 1.6 with transpotision with resection, making the two procedures equivalent to within one unit (TOST, p=0.04). Multivariate analysis showed that preoperative deviation carried highest statistical correlation with final outcomes (p=0.018). Discussion: Foster-Augmented Transpositions appeared to have better post-operative horizontal and vertical alignment than transpositions with resections, possibly due to the larger preoperative deviations in the resection group. When compared to Foster-Augmented Transpositions, the simplicity of transposition with resection and its amenability to reoperation should be considered when a selecting a procedure for patients with complete 6th nerve palsies. Conclusion: Foster-Augmented Transpositions appear more effective at reducing primary esotropia and unwanted vertical deviations in patients with total 6th nerve palsies, but the differences are small and the simplicity of the transposition and resection procedure may make it the procedure of choice in many patients. Accommodative Esotropia (AET) Treatment Utilizing Simultaneous Strabismus Surgery and Photorefractive Keratoplasty H Sprague Eustis MD Pulin Shah D Ochsner Clinic Foundation New Orleans, La Introduction: Accommodative esotropia (AET) is a common cause of acquired esotropia. Pathogenesis varies among patients but usually includes excessive hyperopia and a high AC/A ratio or tight medial recti. The present study reviews an individualized treatment plan combining refractive surgery (PRK) and strabismus surgery to correct these problems. Methods: 14 patients with AET treated were retrospectively reviewed. Patient ages ranged from 11 to 19 yrs. PRK and strabismus surgery were performed on 11 patients and PRK only in 3 patients. The goal was to create a physiologic refractive error, good visual acuity (VA), and straight eyes without correction. Results: All patients were spectacle free at 6 mos. follow up. 26/28 eyes had VA equal to preoperative VA without correction. Two eyes had a 2 line reduction in VA. Alignment results: plus or minus 10 PD: 13/14. Spherical refractive outcomes: 20 of 28 eyes within 1 D of target: 8 eyes within 2 D of target. Astigmatism refractive outcomes: 21/28 eyes <1 D: 3 eyes: 1- 2 D: 4 eyes > 2 D. Two patients complained of halos at night, and one patient had peripheral corneal haze. Additional patients may be added. Discussion: Simultaneous PRK and strabismus surgery is safe and effective in treating AET. Outcomes are skewed for under corrections at 6 mos. and present algorithms need to be revisited. Residual uncorrected astigmatism was seen in 2 patients, yet visual acuity was unaffected. Conclusion: An individualized treatment plan in AET, addressing the causes can result in a physiologic refractive error, good visual acuity, and a spectacle free existence. 138 Long-term Outcomes of Strabismus Surgery in Mobius Syndrome Marlo Galli CO Gregg Lueder MD St. Louis Children’s Hospital, Washington University School of Medicine Saint Louis, MO Electronic Poster 97 Introduction: Mobius syndrome is a rare disorder characterized by presumed congenital sixth and seventh nerve palsies. Approximately half of affected patients have esotropia with limitation of extraocular movements. This study reviewed the long-term outcome of strabismus surgery for such patients. Methods: Retrospective review of five children with Mobius syndrome and congenital esotropia who underwent bilateral medial rectus muscle recessions. Results: All patients had limitation of abduction in both eyes. The age at surgery ranged from 4.5 to 14 months. The preoperative esotropia ranged from 20 to 30 prism diopters (mean 27). The medial rectus muscles were recessed from 4.0 to 6.5 mm. Inferior transposition of the medial rectus muscles was performed in two patients for treatment of associated V-pattern, and two patients also had surgery for vertical strabismus. The final horizontal alignment was < 8 prism diopters in all patients, and all demonstrated some binocularity. Follow-up ranged from 1.5 to 17 years (mean 13 years). Discussion: The presence of relatively moderate angles of esotropia despite marked limitation of abduction and the good response to medial rectus muscle recessions alone suggests that the strabismus in Mobius syndrome is more like that seen in Duane retraction syndrome, rather than congenital sixth nerve palsy. Conclusion: Bilateral medial rectus muscle recession alone is an effective treatment for esotropia associated with Mobius syndrome, with good long-term stability. Novel Technique for Surgical Correction of Small Angle Vertical Deviation Larissa A Habib MD Steven E Brooks MD Columbia University Medical Center - Harkness Eye Institute New York, NY Introduction: Surgical options for adult patients with small angle (<5PD) vertical strabismus and fusion potential are limited, as standard recess/resect procedures are not well suited for such small angles. We describe a novel surgical technique designed to address this subset of patients, and its results in three patients. Methods: The surgery consisted of disinserting the medial and lateral thirds of the superior rectus from the globe, and recessing each pole a pre-determined amount using 6-0 vicryl suture. It was assumed that full muscle recession corrects 3PD/mm. Because only 2/3 of the muscle is recessed this is reduced to 2PD/mm. Furthermore, the recession increases in a linear fashion from the intact central third out to each pole, reducing the weakening effect by 50%, yielding a final expected effect of 1PD/mm. Results: Patient Age (yrs) Preop (PD) Recession (mm) Postop (PD) Length F/U 1 53 2 RHT 2.5 ortho 3 yrs 2 38 3-4 RHT 3 ortho 2 yrs 3 59 4 RHT 4 ortho 2 weeks Discussion: In each case the dose-response matched the predicted effect, and appeared to demonstrate long term stability. There were no complications. The procedure is potentially revisable in the case of over or under-correction, and does not exclude the use of adjustable sutures, features which are not available with marginal or central tenotomy. Conclusion: Our procedure appears to be a safe, effective, titratable technique for correcting very small angle vertical strabismus in adults who cannot, or do not wish to, wear prisms.

Methods: The medical records of all patients undergoing bilateral weakening surgery for esotropia by a single surgeon between January 1, 2002, and July 1, 2014 (n=544) were reviewed. Exclusion criteria included those with prior strabismus surgery, unilateral surgery, strengthening procedures, vertical or superior oblique surgery, and those wearing hyperopic spectacles for accommodative esotropia. Additionally, all patients had to have a 1 week and 6 week postoperative exam, and have </=8 PD of deviation at their 6 week examination. Results: Ninety-five (17.5%) of the 544 met inclusion criteria. Surgery was performed at a median age of 3.7 years (range, 7 months to 86 years) for a median esodeviation of 35 (range, 12 to 70) prism diopters. Among the 73 patients under 11 years, the immediate mean postoperative alignment was 9 PD of exotropia (range, 14 ET to 30 XT) compared to a mean of 2 PD of exotropia (range 9 ET to 30 XT) in the 22 patients 11 years or older (p=0.001). Discussion: Esotropic children who undergo successful strabismus surgery have a greater immediate postoperative overcorrection compared to adults. Recognizing these differences is useful in predicting and anticipating motor outcomes for strabismic patients of various ages. Conclusion: Successful bilateral strabismus surgery for esotropic children results in a significantly greater overcorrection in the immediate postoperative period compared to adult patients. Electronic Poster 100 The Newcastle Control Score A Predictor Of Surgical Outcome In Distance Intermittent Exotropia? Mr Hugh Jewsbury, Mr Patrick Watts Cardiff Eye Unit, Cardiff, UK Introduction: The Newcastle Control Score (NCS) is used to quantify observed control of distance intermittent exotropia(1). It has been demonstrated as a valuable tool in predicting those likely to require surgical intervention when compared to historical criteria for listing(2). However, whether the NCS predicts actual surgical outcome is unclear. This study aims to investigate if a relationship exists. Methods: Retrospective analysis of patients’ notes undergoing strabismus surgery for distance intermittent exotropia at a UK teaching hospital between February 2002 and February 2014. The primary end point was the magnitude of deviation for near and distance at 3 months post operatively. Results: 67 patients included with 35 of them male. Mean age 12.3 ± 5.19yrs. The differences in pre-operative NCS for distance, near, home and total control were compared between patients achieving an excellent result (within 10D of orthophoria) and those achieving a poor outcome (>10D of orthophoria). There was no statistical difference between any groups (p = >0.3). There was no statistical difference in the number of patients achieving an excellent result (within 10D of orthophoria) when divided into those with a low pre-operative NCS (≤5) and a high pre-operative score (≥6), Chi-square statistic 0.042, p = 0.84. Discussion: Whilst the NCS may predict those that are likely to undergo surgery, it does not appear to predict successful outcomes. Conclusion: Additional tools need to be developed to help predict surgical outcomes in patients with intermittent exotropia in order to better inform surgeons, patients and families of the need for surgery and likely success.

We investigated factors potentially augmenting this difference. Methods: Review of our database of outcomes after surgical remediation of exotropia (years 2007 - 2013) identified those with alignment documented both by SPCT and APCT at the same examination. Patients were divided into those demonstrating no difference, and those with signficant difference(1) between SPCT and APCT. Age, visual acuity, fusion, size of pre-operative deviation, intermittency versus non-intermittency, type of deviation, alphabet patterns, inclusion of resection during repair, and post-operative exotropia versus esotropia were among factors analyzed. Results: 273 patients had available SPCT and APCT measures at distance, and 318 at near. We found an increased difference between SPCT and APCT at distance for those with intermittent exotropia (p=0.028), larger pre-operative angle (p=0.003), surgery without resection (p=0.015), and post-operative exotropia rather than esotropia (p<0.001). Post-operative exotropia rather than esotropia increased this difference at near (p=0.005). Performance of a resection had a similar impact on those with intermittent versus non-intermittent exotropia. Post-operative alignment within 10 prism diopters of orthophoria by SPCT was associated with much greater difference between SPCT and APCT than those with greater post-operative misalignment. Discussion: Although surgeon’s choice to resect narrows the range between SPCT and APCT at distance effectively improving control of residual misalignment, independent risk factors may remain including presence of intermittent exotropia, larger pre-operative deviation and undercorrection. Conclusion: Surgical approach can impact the SPCT versus APCT difference. Outcomes based on SPCT versus APCT are not readily comparable.

Improved maintenance of binocularity in ocular neuromyotonia after strabismus surgery Anna Kim MD Stacy Pineles MD Federico Velez MD University of California Los Angeles; Stein Eye Institute Los Angeles, California Introduction: Surgical treatment for ocular neuromyotonia has not yet been described. Variable baseline deviation and episodic spasms make correction challenging in these patients. We report the strategies and outcomes of surgery in patients with ocular neuromyotonia. Methods: Three patients with ipsilateral cranial sixth nerve palsy and ipsilateral lateral rectus muscle ocular neuromyotonia who underwent strabismus surgery were included. All patients had a history of radiation therapy for tumors, including a pituitary tumor invading the cavernous sinus, an invasive nasophargyngeal carcinoma and a clival chordoma. Preoperative and postoperative data are described and analyzed. Results: All patients were female with a mean age of 61±14 years. The delay in onset of neuromyotonia post-radiation was 10.3 years (range 6-13). Preoperative ocular alignment during the resting phase measured 41±30 PD of esotropia (range 18-75 PD) at distance and 37.6±41 PD (range 12-85 PD) at near. All patients developed a large angle exotropia with limited adduction during the spasmodic phase. Postoperative follow-up ranged from 8 months to 2 years. Postoperative ocular alignment ranged from 0-8 PD of esotropia in all gaze positions. Neuromyotonic paroxysms were significantly reduced in two patients. Two patients demonstrated stereopsis post-operatively. Discussion: Strabismus surgery is a safe and effective procedure to achieve single vision, fusion and ocular alignment in patients with ocular neuromyotonia. Surgery did not result in worsening of neuromyotonic spasms. Conclusion: Surgical management is a safe alternative in patients who do not respond to medical treatment. 141 Electronic Poster 102 Electronic Poster 103 Long-Term Surgical Outcome and Developmental Abnormalities in Infantile Exotropia Gregg Lueder MD Marlo Galli CO St. Louis Children’s Hospital, Washington University School of Medicine Saint Louis, MO Introduction: Because infantile exotropia may be associated with developmental delay, some have recommended neurologic evaluations for all such patients. We evaluated a group of patients with infantile exotropia with regard to associated developmental problems and surgical outcomes. Methods: Retrospective review of children who had surgery for exotropia that presented within the first year of life, including patients with developmental delay. Patients with <1 year postoperative follow-up were excluded. Surgery was considered successful if the horizontal deviation was less than 10 prism diopters (PD). Results: Twenty-six patients were included. Age at presentation ranged from 2-10 months. The range of exotropia was 20-95 PD. Ten patients (38%) had developmental delay. Nine of these had systemic conditions that were recognized at the time of their initial evaluation. Age at surgery ranged from 4-18 months. Successful outcomes occurred in 10/26 (38%) patients after one surgery and an additional 13 (50%) patients after two surgeries. Three patients underwent 3 or more surgeries. Follow-up ranged from 1-16 years (mean 7 years). Discussion: Developmental delay is common in patients with infantile exotropia, but the cause of delay is usually recognized at the time of the initial evaluation. The need for more than one surgery is higher in infantile exotropia than in other forms of childhood strabismus. Conclusion: Routine neurologic screening of otherwise normal infants with infantile exotropia is not indicated. Most children achieve good long-term alignment with one or two surgeries. Electronic Poster 104 A Comparison of Surgical Outcomes in Patients with Unilateral Cranial Nerve VI Palsy. Kimberly S Merrill CO Laura Lenius BS Erick D Bothun MD Stephen P Christiansen MD University of Minnesota Department of Ophthalmology and Visual Neuroscience and Boston University School of Medicine Department of Ophthalmology Minneapolis, MN and Boston, MA Introduction: A significant abduction deficit complicates surgical management of patients with CN VI palsy. We compared the outcomes of four surgical interventions in patients with unilateral CN VI palsy who had a -3 or greater abduction deficit: botulinum toxin (BTX-A) alone, horizontal surgery alone, vertical transposition alone, and vertical transposition plus BTX-A. Methods: With IRB approval, we performed a retrospective chart review for patients with unilateral CN VI palsy who had surgery between 1998 and 2013. Inclusion criteria were -3 or greater abduction deficit, stable preoperative alignment > 6 months, and > 6 months postoperative follow-up. Results: Of 82 patients with CN VI palsy, 26 met inclusion criteria. Mean duration of follow-up was 18 months (6-51 mo). There was a trend towards better alignment at distance in patients treated with vertical transposition with or without BTX-A, although these patients were more likely to develop a consecutive exodeviation at distance or near (11/19, 58% vs. 1/7, 14%). Residual esotropia was most common in patients treated with BTX-A alone. Discussion: In this study, horizontal transposition of the vertical rectus muscles with or without BTX-A resulted in better alignment than horizontal muscle surgery or BTX-A alone. Conclusion: A significant abduction deficit is an indication for transposition in patients with CN VI palsy but this procedure may result in a consecutive exodeviation. 142 A modified technique for strabismus surgery in the presence of a scleral buckle Mitra Nejad Anna J Kim Stacy L Pineles Federico G Velez Jules Stein Eye Institute Los Angeles Electronic Poster 105 Introduction: Scleral exoplant implantation for retinal detachment can cause strabismus. Removing the exoplant has minimal effect in ocular alignment, while increasing the risk of scar tissue formation and retinal re-detachment. Scleral exoplants may interfere with EOM reattachment during strabismus surgery especially during recessions and adjustable suture techniques where the final position of the muscle insertion after adjustment is not always clear to the surgeon. We describe a surgical technique to perform strabismus surgery including adjustable sutures in patients with scleral exoplant without removing or modifying the exoplant. Methods: All patients with scleral exoplant who underwent strabismus surgery preserving the integrity of the scleral exoplant were included in the study. Recessed muscles and those operated on adjustable sutures were repositioned between the scleral exoplant and the sclera leaving the exoplant intact. Analysis included motor and sensory results, easiness of adjustment and postoperative complications. Results: Six patients were included. Mean age was 45+/-2 years. Time between scleral exoplant implantation and strabismus surgery ranged between 0.5-38 years. Six rectus EOM were recessed and 2 were resected, all on adjustable suture. All rectus EOM excluding the inferior rectus were operated on. Postoperative follow up ranged between 6-24 months. Discussion: No patient developed retinal re-detachment, exoplant extrusion, EOM slippage or significant ocular alignment shift following the postoperative course. If needed, EOM adjustments were performed without difficulties. Conclusion: Strabismus surgery, including adjustable sutures, can be performed without affecting the integrity of the scleral exoplant in patients with previous retinal detachment surgery. Surgical success in strabismus surgery with conventional vs Hang-back technique Cristian M Salgado MD Alvaro E Morgado MD Bernardita M Alamos MD Sylvia A Araneda MD Pablo Altschwager MD Felipe A Sanhueza MD Pontificia Universidad Catolica de Chile, Santiago, Chile Introduction: Muscle recession using the suspension technique (hang-back) is an alternative to conventional (scleral) surgery with some advantages. We compare the surgical outcomes of both techniques in Chilean patients. Methods: We conducted a prospective, randomized, comparative study of patients undergoing scleral or hang-back surgery between June 2011 and December 2013. Patients had horizontal strabismus, full motility and visual acuity greater than or equal to 20/80. Patients with neurological disorders or genetic syndromes, previous eye surgery, vertical strabismus and A or V anisotropia were excluded. The main outcome was motor successful surgery established as a residual deviation of 10 or fewer prism diopters. For the comparison of groups, Fischer’s exact test was used and p values < 0.05 were considered significant. Results: Thirty-nine patients were studied. Twenty-three patients underwent scleral surgery and sixteen underwent hang-back surgery. The average age of the patients was 94 months, and 20 patients were male (51.3%) and 23 patients had esotropia (59.0%). There were no significant differences between the groups. The average follow-up period was 11.6 months. The surgical success rate was 76.9% in the whole group at the last follow up: 69.6% in the conventional group and 87.5% in the hang-back group (p = 0.26). No severe complications occurred in any group. Discussion: Although there was a tendency of better long-term stability with the hang-back technique, both techniques produced similar surgical success rates that were not statistically different. Conclusion: Hang-back surgery is a safe and effective alternative to strabismus surgery with several advantages. References: 1. Rajavi Z, Ghadim HM, Nikkhoo M, Dehsarvi B.

Medial rectus recession was done as indicated by passive ductions. Adjustment done after 5 hours of surgery. Results: Mean change of esodeviation was from 49.4+13.62 prism diopter (PD) to 1.3± 2.66 PD in group 1 and from 45.8 ± 9.56 PD to 4.3± 4.47 PD in group 2.The inter group difference was significant, p value=0.016. Orthotropia (<8pd) was achieved in 9/10cases in group 1 vs 5/10 in group 2(p=0.04). Percentage improvement in BSV was 560 ±381.22 vs 246 ±131.04 in group 1 and 2 (p value=0.047). The grade of abduction improved to 3.3+1.41 vs 2.1+.87 respectively from the preoperative 0.9+.56 in each group. The difference between the two groups was significant (p=0.015). No vertical deviations and evidence of anterior segment ischemia noted Discussion: Postoperative diplopia can be intriguing and is better controlled by the adjustable technique. Conclusion: In management of lateral rectus palsy adjustable partial VRT holds statistically significant advantage over conventional partial VRT giving better improvement in abduction, total binocular single visual fields and achieving orthotropia. Electronic Poster 108 Long-term stability of postoperative deviation in sensory strabismus: surgery of the dominant or non-dominant eye. Federica Solanes MD, Bernardita Alamos MD, Cristóbal Morales MD, Cristián Salgado MD Pontificia Universidad Catolica de Chile Santiago, Chile Introduction: The non-fixing eye (NFE) is typically operated to improve sensory strabismus (SS). It is believed that surgery on the fixing eye (FE) would provide more longterm stability. To evaluate the surgical success, stability and complications of monocular surgery in FE versus NFE in SS. Methods: Descriptive prospective study which included patients with SS, with deviations from 15 to 70 with modified Krimsky (MK), visual acuity logMAR >0,3 in FE and <0,7 in NFE. Secondary strabismus and previously operated were excluded. Monocular surgery was performed according to tables of Wright (endotropia and exotropia <50) and Rosenbaum (exotropia >50). Surgery was based on the inability to operate on the NFE or the decision of the patient providing informed consent prior to the procedure. We assessed postoperative surgical success (MK for endotropia +10 to -5 and -10 to +5 for exotropia), complications and stability at 1 week and 1, 6 and 12 months. Results: We operated 9 patients: in 5 the NFE and in 4 the FE. The rate of success on the FE was 100% in all controls. On the NFE, the rate of success at 1 week was 60%, 50% at 1 month, 40% at 6 and 12 months (p0.119). No patients had complications that threatened their vision. Discussion: Although the number of patients in our series is small, those who underwent surgery on their FE tended to improve surgical success and stability for 12 months without complications that threatened their vision. Conclusion: Surgery on FE shows tendency to be better in success and stability. References: 1. Dotan G.

The number of diagnosed cases has risen over recent years [2]. We investigated whether this increase is reflected in the number of surgeries performed for DI, and if rising numbers are associated with a possible increased awareness among eye care professionals that strabismus in adults is treatable. Methods: Medical records from 2006 to 2013 were searched for surgical DI cases in a private practice specializing in adult strabismus. For each patient, the referral source was categorized as specialist, general ophthalmologist, optometrist, or primary care practitioner. Results: A total of 120 patients with DI received surgery (recession of one lateral rectus muscle [3].) The annualized number of DI surgeries increased from 12 to 26 (P=0.02), representing a change from 4% to 12% of all adult surgeries. The proportion of DI patients referred by general ophthalmologists increased from 23% to 53% (P=0.02), the proportion referred by specialists (neuro-ophthalmology; neurology; oculoplastics; cataract or retinal surgeons) decreased from 60% to 27% (P=0.01), while the proportion of referrals from optometrists (18%) and primary care practitioners (8%) remained approximately constant. Discussion: We found an increase in the relative and absolute annual number of surgeries for adults with DI and a shift in the referral pattern, with more patients being referred by general ophthalmologists. Referrals from optometrists remain constant and comparatively low. Conclusion: The increased number of DI surgeries mirrors the reported increased incidence of DI. Attention in the general ophthalmic literature may have led to an increase in referrals to the strabismus surgeon by general ophthalmologists. References: 1.

Rectus muscle advancement for the treatment of ocular misalignment following scleral buckle Kirstin L Tawse Mitchell B Strominger Shelley Klein Tufts Medical Center Boston, Massachusetts Introduction: Reestablishment of ocular alignment following scleral buckle is fraught with difficulty and limited literature. The primary etiology of the deviation is thought to be secondary to scarring of the extraocular muscles and restrictive in nature. We report our experience in the surgical management of these patients. Methods: We present a retrospective chart review of 10 patients who underwent eye muscle surgery since 2010 for the reestablishment of ocular alignment following scleral buckle. Preoperatively, there were five patients with exotropia, three with esotropia and two with hypotropia. Results: All patients were discovered intraoperative to have a rectus muscle scarred posterior to the buckle and in the direction away from the deviation, causing posterior fixation of the muscle with underaction. In all cases the posterior fixated muscle was advanced to the original insertion using an adjustable suture. Four of these cases were combined with a resection of the advanced muscle. In our cases prior to June 2012, exploration of the opposing muscle also demonstrated posterior scarring allowing further recession to be impossible. Discussion: Posterior scarring of the rectus muscle behind the scleral buckle with underaction in the direction away from the deviation appears to play a significant role in the ocular misalignment following scleral buckle placement. Conclusion: Surgical advancement with possible additional resection of these posterior scarred muscles is critical in reestablishing ocular alignment. In many cases, exploration of the opposing muscle is unnecessary because they too are found scarred posterior, thus prohibiting further recession. 145 Electronic Poster 110 Electronic Poster 111 Poster Withdrawn Electronic Poster 112 Surgical Treatment of Divergence Insufficiency Esotropia Chris Y. Wu, B.S., Monte A. Del Monte, M.D. Department of Ophthalmology and Visual Sciences, WK Kellogg Eye Center University of Michigan, Ann Arbor, Michigan 48105, USA Introduction: Several surgical protocols for divergence insufficiency pattern of esotropia (DPE) have been reported. We aim to compare the effectiveness of isolated unilateral medial rectus (MR) recession with unilateral MR recession-lateral rectus (LR) resection. Methods: We analyzed 33 patients who underwent surgery for DPE by one surgeon at our institution between 1996 and 2014; most recessions were performed on adjustable sutures. DPE was defined by exam findings of diplopia at distance with distance esodeviation >/= 5 PD more than at near deviation. Patients with distance esodeviation </= 20 PD underwent isolated MR recession, while those with esodeviation > 20 PD underwent combined recess-resection. Results: Eighteen patients underwent MR recession while 15 underwent recess-resection. Mean preoperative distance/near esodeviations were 12.83/2.44 PD for recessions and 25.47/15.26 PD for recess-resections (P < 0.001). For recessions, final dosages were 1.96 ± 1.02 mm greater than that recommended by Park’s Surgical Tables for esotropia, while recess-resections required 1.18 ± 1.64 mm more recession and 0.37 ± 1.36 mm more resection. Post-operatively, recession patients needed prisms more often (38.9% vs. 6.7%; P = 0.046) though reoperation rates did not differ (11.1% vs. 0%; P = 0.489). Recess-resections were more likely to cause early lateral incomitant exotropia (P = 0.033). Discussion: Unilateral MR recession for ET </= 20 PD and unilateral recess-resection for ET > 20 PD effectively treats DPE with a 6% cumulative reoperation rate. Larger dosages were needed for MR recessions than recommended, affirming the utility of adjustable sutures. Adding ipsilateral resection to solitary MR recession may be beneficial given the high rate of post-operative diplopia requiring prism correction. Conclusion: Several effective surgical protocols exist for DPE though better-powered comparative studies are still needed. 146 The newly sighted match seen with feltan answer to Molyneux question from 1688 Electronic Poster 113 Itay Ben-Zion MD Goldschlager eye insitiute, Sheba medical center Sackler Faculty of Medicine. Tel-Aviv, Israel Introduction: William Molyneux raised a question that was only philosophical until recently : Imagine, Molyneux wrote, that a man blind from birth that has learned to identify objects only through his sense of touch is suddenly able to see. The puzzle is: whether he could by his sight only know and name the objects? The answer to Molyneux question will resolve a fundamental uncertainty about the human mind: Do we recognize identities between seen shapes and felt ones by associative learning or by using intrinsic connections between these modalities Methods: In Ethiopia we conduct a study of kids with bilateral Congenital Cataract who present late for medicl treatment (age>6 years old) with sensory nystagmus and positive family history Vision preoperative is LP OU, under general anaesthesia we perform cataract extraction and foldable P/C IOL bilateral. Vision and object recognition is performed immediately after bandages removal the next day Results: we demonstrate (with video recording) visual performance, recognition and naming of objects by one child of the cohort preop and immediately following sight restoration, the child is able postop with sight only to name objects he has named preop by touch only, Visual acuity was 2 meter finger count (tested immediately following the recognition task) Discussion: This child demonstrates tactile-visual transformation thus answering positively to the question Molyneux raised nearly 250 years ago Conclusion: Revealing how we learn to see is crucial for our understanding of the entire visual processing possibly enabling us in the future with better treatment modalities New trends in childhood vision impairment in a developed country Susan Carden MBBS, FRANZCO, FRACS, PhD Shivanand J Sheth MS, DOMS, FICO, FAICO Chengde Pham MBBS, B.Med.Sci Jill Keeffe OAM, PhD The Royal Victorian Eye and Ear Hospital, Melbourne, Australia Introduction: The Educational Vision Assessment Clinic (EVAC) reviews school children aged 4 to 18 years with vision impairment, in the State of Victoria, Australia, to determine their eligibility for educational support. The clinic is conducted at the Royal Victorian Eye and Ear Hospital, Melbourne, and is staffed by a pediatric ophthalmologist, an education officer and an educational psychologist. Methods: A retrospective chart review was undertaken of all students (n=543) attending EVAC during the period from 2003 - 2012 (10 years). Demographic data analyzed included: age, gender, visual acuity, diagnosis, and eligibility for educational support. Results: 355 (65%) students were eligible for educational assistance (best corrected visual acuity <20/60 in the better eye and/or a field of vision constricted to <20 degrees). Of those, 106 had a VA <20/200 and/or field of vision < 10 degrees. The commonest causes of visual impairment amongst the children eligible for educational assistance were: retinal dystrophies (16%), optic nerve pathology (15%), ocular albinism (13%), congenital nystagmus (8%), cortical visual impairment (5%), retinopathy of prematurity (5%), and congenital cataract-related low vision (4%). Discussion: EVAC is instrumental in ensuring that students with low vision, from any socioeconomic background, benefit from specialist services. It is likely that most students with significant vision impairment, including those with multiple disabilities, in the State of Victoria, attend this free clinic. Conclusion: The treatable and potentially preventable causes of vision loss such as retinopathy of prematurity and cataract now make up <10% of cases of significant vision loss in school children in Victoria, Australia.

This study evaluates the feasibility of using atropine 0.01% in a private practice, documents side-effects, and reports on myopic progression. Methods: Patient charts treated by the author with atropine 0.01% for greater than one year from February 2012 to present were retrospectively reviewed. These patients were compared to a control set who were offered atropine, but deferred, and had two cycloplegic refractions. Results: Seven patients were treated with atropine 0.01% and 5 in the control group. Both groups had one female. One of the 7 atropine patients was Asian, 1 Hispanic and 5 Caucasian. In the control group, 3 were Asian, 1 Hispanic and 1 Caucasian. The average age at the beginning of treatment was 10 years versus 9 in the control group(p=0.03). The treatment group had progressed by 1.20 diopters in the previous year versus 1.79 diopters in the controls(p=0.10). Prior to treatment, the range of spherical equivalent myopia was -3.00 to -12.00 diopters in the atropine group and -1.00 to -7.00 diopters in the controls. After an average of 20 months on atropine, the treatment group progressed by 0.40 diopters versus 0.81 diopters after an average of 11.5 months in the control group(p=0.005). Patients in the atropine group had mild difficulty reading for less than 4 weeks; one had headaches. Discussion: Most patients in this study tolerated the use of atropine 0.01% well without side effects and instilled the drops for one year. The treatment group showed a significant decrease in myopic progression. Conclusion: The use of atropine 0.01% is well tolerated and effective in a private practice with a variety of racial backgrounds. References: 1.

Methods: This study will demonstrate and discuss survey results from over 400 pediatric ophthalmologists in the United States. The Survey included 21 commonly encountered clinical situations. Results: Each clinical situation will be analyzed and presented with percentage of responses in bar figure fashion. We will also provide a case-based approach to analyze the most commonly encountered clinical situations in prescribing glasses in preverbal children. Discussion: The results will provide: (1) better understanding of when and how to prescribe eyeglasses in commonly encountered clinical situations (2) learning the simplified rules for prescribing eye glasses in preverbal children. Conclusion: The survey reveals valuable data to explain how and why these decisions in prescribing eye glasses in preverbal children are made by experienced pediatric ophthalmologists. The survey analysis reveals useful guidelines to help maximize vision, promote fusion and prevent the development of amblyopia in preverbal children. 148 Parent Experiences and Perspectives on Medical Services for their Children with Albinism: A qualitative study Kelly E Lusk PhD, CLVT Anne L Corn EdD Terry L Schwartz MD Cincinnati Children’s Hospital Medical Center/University of Cincinnati College of Medicine Cincinnati, OH Electronic Poster 117 Introduction: For parents of children with visual impairments, including albinism, it is often difficult to navigate the array of medical services. The purpose of this study was to investigate experiences and perspectives of parents regarding their children’s medical care (specifically, but not limited to, pediatric ophthalmologists and primary eye care physicians) via guided focus groups. Methods: Parents of children with albinism were recruited through participation at the National Organization of Albinism and Hypopigmentation Conference in July 2014. Focus groups were conducted on four separate occasions during the conference. Results: Thirty-seven parents from across the U.S. and Canada participated in focus groups. Overall themes from the focus groups included knowledge level of albinism, coordination of services/interdisciplinary approach to services, referral practices regarding pediatric low vision services and local school systems, and expectations for future visual and independent functioning. Discussion: Parents had both positive and negative experiences/perspectives regarding medical services. Many parents were not aware of some medical services/resources that other parents discussed. There are wide differences in parents’ statements about how medical services are provided to children with albinism. Conclusion: These data give insight into how families perceive experiences with medical professionals, including pediatric ophthalmologists. This information can aid pediatric ophthalmologists and their staff, in understanding how and why parents may be satisfied or dissatisfied with the care their children receive. A quantitative study is currently underway on this same topic to further investigate and provide additional guidance to pediatric ophthalmologists and other medical professionals regarding the care of patients with albinism.

Pando 5 Etapa San Miguel, Lima 32 - Peru Introduction: The purpose of this study is to determine if students with neurodevelopmental disorders and significant refractive errors, can demonstrate behavioral and communication improvements by adapting to wearing glasses. Methods: Sixty students with neurodevelopmental disorders at an educational center in Lima, Peru were identified by a pediatric ophthalmologist as needing glasses to improve functional vision, and prescribed accordingly. Ten months later the parents completed a survey regarding the use of glasses. Parents reported on the frequency of use, the activities and locations when glasses were used and any changes in behavior when wearing the glasses. Results: Fifty-one (85%) students were using the glasses 10 months after they were prescribed. Thirty-three (55%) used glasses at home, at school and in the street, with the remaining students using glasses in on or two of these environments. Fourteen (23%) of the students reportedly cleaned and cared for their own glasses. Forty-three (72%) of the parents surveyed reported seeing positive behaviors ranging from increased help around the house to more interest in books and improved general behavior and communication when glasses were worn. Discussion: Ten months after glasses prescription a vast majority of the students had obtained glasses and were using them. Conclusion: Visual impairment in students with neurodevelopmental disorders is under diagnosed. The results collected from the current study demonstrate that students with developmental disorders and vision problems can adapt to wearing glasses when given proper diagnosis, intervention, and support leading to an increase in quality of life.

Michael Cotten MD, MHS Sharon F Freedman MD Cynthia A Toth MD Duke University School of Medicine Durham, NC Introduction: We relate posterior segment microanatomy from perinatal spectral-domain optical coherence tomography (SDOCT) to visual acuity (VA), brain abnormalities, and neurodevelopment. Methods: Twelve infants (10 preterm, 2 term birth), imaged in the nursery with portable SDOCT, had VA and sensorimotor testing at age 9-15 months (grating acuity) or 4-5 years (optotype), and medical records reviewed for brain magnetic resonance imaging (MRI) reports and Bayley Scales testing at age 18-24 months. Two children with retinal detachments or dense vitreous hemorrhages and suboptimal acuity were excluded from analysis. Results: Five children with age-appropriate macular microanatomy without edema on perinatal SDOCT had optimal (> 20/40) or within normal limits (grating acuity) VA. Five children with perinatal macular edema and some with additional OCT anomalies had suboptimal VA (in 9/10 eyes) and either sensorimotor deficits, MRI abnormalities or poor neurodevelopment. Macular edema persisted in one infant through 9 months corrected age. Discussion: Maturation of the visual system and evolution of retinal anomalies can be monitored with posterior segment SDOCT. Macular edema on perinatal SDOCT appears as a potential indicator of retinal or visual pathway function and potentially of global problems in early brain development. Conclusion: Retinal microanatomy might predict acuity and relate to other central nervous system events, but additional studies are needed to determine the range of normal microanatomy in infants and how this relates to vision and neurodevelopment. Electronic Poster 120 Outcome of Optical Iridectomy in Peters anomaly Sirinya Suwannaraj, Oriel Spierer, Kara M. Cavuoto, Ta Chang Peter Chang, Craig McKeown Bascom Palmer Eye Institute Miami Introduction: Peters anomaly is a rare congenital corneal opacity. It may result in profound amblyopia if the opacity involves the visual axis. The purpose of this study is to evaluate the outcomes of optical sector iridectomy in children with Peters anomaly. Methods: The medical records of all patients diagnosed with Peters anomaly who underwent optical iridectomy during the years 2002-2014 were reviewed. Data collection included visual outcome and surgical complications. Results: Twelve eyes (8 patients) were included in the study. Mean age at the time of surgery was 17.0 ± 28.8 months (range 1.5-92). Mean follow-up time was 38.5 ± 29.9 months (range 4-94). A red reflex was obtained in all of the patients after surgery. Mean visual acuity improved from 2.4 to 2.0 logMAR at last follow-up visit (p=0.04). No intraoperative or postoperative complications occurred. Mean intraocular pressure at last followup was 17.8 ± 3.2 mm Hg (range 12-24) with none of the patients requiring treatment for ocular hypertension. Discussion: The conventional treatment for potentially amblyogenic Peters anomaly is early penetrating keratoplasty. However, corneal transplantation in young children is associated with a high graft failure rate and other post-operative complications, including glaucoma. Optical sector iridectomy is an alternative in cases where there is a clear peripheral corneal zone. Our study found that children who underwent optical iridectomy had improvement in visual acuity and a low complication rate. Conclusion: Optical sector iridectomy is a safe and effective alternative for penetrating keratoplasty in certain patients with Peters anomaly. References: 1. Sundaresh K, Jethani J, Vijayalakshmi P.

Methods: Children with hypermetropia > 5 dioptres were identified from a paediatric ophthalmology database. The age, gender, visual acuity, refraction, presence of strabismus, duration of follow up and the systemic associations were recorded. Children with < 6 months follow up or where a crowded acuity could not be recorded were excluded. Results: 103 children were included with 57 of them boys. The mean age at presentation and final follow up was 3.6 ±1.9 years and 6.3±1.8 years respectively with a mean follow up of 33±21 months (range 6 -124 months). Mean hypermetropia was 7.07 ±1.5 dioptres. 50% of children had an esotropia. The mean presenting and final visual acuity was 0.46± 0.28 LogMAR and 0.21±0.15 LogMAR respectively. There was a significant association between the degree of hypermetropia and the final visual acuity (P<0.05). There was no association between the age of presentation and the final visual acuity. Residual amblyopia was present in 34%. 11 children had developmental delay or a syndromic condition. Discussion: The prevalence of residual amblyopia in this study reinforces reports of suboptimal visual outcomes in high hyperopes1,2 and refutes previous studies suggesting excellent visual outcomes in these patients3. Carers of high hyperopes can be better informed at the outset of treatment regarding the possible visual outcomes and associations of high hypermetropia. Conclusion: A third of children with high hypermetropia have residual amblyopia. A significant number of children have strabismus. References: 1. Klimek DL, Cruz OA.

Methods: The University of California Los Angeles (UCLA) preschool vision program (UPVP) screened low income children aged 3-5 years with the Retinomax autorefractor. Children who failed screening were fully examined on the UCLA Mobile Eye Clinic. Amblyopia was defined as unilateral if there was a >/=2 line difference in the best corrected visual acuity (BCVA), and bilateral if BCVA was <20/50 for children <4 years old, and <20/40 for children >/=4 years old. Results: Between August 2012 and May 2013, 11,260 children were screened by the UPVP. Of those, 1007 failed and were examined by an ophthalmologist. Glasses were prescribed for 73.5%. Uncorrected visual acuity was 0.4±0.2 (logMAR mean±SD), and BCVA was 0.2±0.1. Of the 85% cyclopleged, 57.4% had hyperopia (spherical equivalent (SE)>/=+0.50D) with a mean of +2.50D, and 20.8% had myopia (SE</=-0.50D) with a mean of -1.40D. A total of 71.3% had astigmatism >/=1.50D. Mean astigmatism was 1.50D (range 0-5.75D). Most children (76%) were corrected to ≥20/30. Refractive amblyopia was found in 9% of those examined, or 0.8% of the original population. Of the amblyopes, 76% were unilateral. Discussion: Screening by the UPVP led to diagnosis and early treatment of uncorrected refractive errors. By treating children early, amblyopia can be prevented. Conclusion: Vision screening has been recommended for children aged 3-5 years. Preschool vision screening should become an important part of child care and preventive health. 151 Electronic Poster 122 Electronic Poster 123 Brückner test, a novel technique for the rapid detection of refractive errors in children by the paediatricians Piyush Jain Vaibhav Gode Mihir Kothari Jyotirmay Eye Clinic, Thane, India Introduction: Purpose: To present the efficiency of Brückner test in detection of ametropia when used by a pediatrician. Methods: In this prospective double masked cohort study, a paediatrician performed the Brückner test in class room of a school in dark lighting condition using a direct ophthalmoscope followed by the same test being performed by a masked ophthalmologist. Findings of the test were noted as emmetropia, hyperopia or myopia. For the purpose of the analysis, the data of hyperopia and myopia was clubbed into a single category - ametropia. The sensitivity, specificity, predictive value and clinical agreement were calculated from 2x2 Bayesian table. The findings of the paediatric ophthalmologists were considered gold standard. The technique of Brückner test used in this study has been already validated against the cycloplegic refraction and vision assessment and published previously.1 Results: 236 eyes of 118 subjects were examined.. The time taken to complete this test was < 10 seconds per subject. Ophthalmologist identified 59 eyes as ametropic (12 hyperopic and 47 myopic eyes) and 177 as emmetropic compared to 61 eyes as ametropic and 175 emmetropic by paediatrician. At prevalence of 25.9%, the sensitivity of the Brückner test by paediatrician was 90.2%, specificity was 97.7%,predictive value of the positive test was 93.2% and predictive value of the negative test was 96.6%. Clinical agreement (kappa) between the ophthalmologist and the paediatrician was 0.9. Discussion: Conclusion: Brückner test is an excellent tool for the detection of significant refractive errors in the hands of paediatrician to rapidly screen the children for ametropia.

Electronic Poster 124 High Specificity of the Pediatric Vision Scanner in a Private Pediatric Primary Care Setting Reed M Jost MS David Stager, Jr MD Lori Dao MD Scott Katz MD Russ McDonald MD Eileen E Birch PhD Retina Foundation of the Southwest, Dallas, TX Introduction: The Pediatric Vision Scanner (PVS) directly detects strabismus and amblyopia by analyzing binocular scans for birefringence that, due to the organization of the radially arranged Henle fibers, is characteristic of steady, bifoveal fixation. In a pediatric ophthalmology office setting,1 we found that the PVS had 97% sensitivity and 87% specificity for detection of strabismus and amblyopia. However, this study did not directly assess performance of the PVS in a primary care screening setting, where it is designed to be used. Here we report PVS specificity and positive likelihood ratio for a cohort of children screened in a pediatric primary care setting. Methods: 95 children (2-6y) were screened with the PVS and SureSight™ Autorefractor in a pediatric primary care setting. Each test yielded a recommendation of ‘pass’ or ‘refer.’ All children received a gold-standard comprehensive ophthalmic exam by a pediatric ophthalmologist who was masked to the screening results. Results: Screening success rates were 93% for PVS and 92% for SureSight™. At the goldstandard exam, one child was identified as having anisometropic amblyopia; 94 had normal exams. Both the PVS and SureSight™ referred the amblyopic child. The PVS passed 78 of 88 children with no strabismus or amblyopia (90% specificity; 95%CI: 82-98%). In comparison, the SureSight™ passed 73 of 87 children with no strabismus or amblyopia (85% specificity; 95%CI: 75-95%). Positive likelihood ratios were 9.7 (95%CI: 4.4-21.3) for PVS and 6.6 (95%CI: 3.5-12.5) for SureSight™. Discussion: In this ongoing study of the PVS in a pediatric primary care setting, results were comparable to the 87% specificity reported previously for an large cohort (n=300) tested in an ophthalmology practice with high prevalence of strabismus and amblyopia.1 In a pediatric primary care setting, the PVS had higher specificity and positive likelihood ratio compared to the SureSight™, resulting in fewer over-referrals of children with no strabismus or amblyopia. Conclusion: Preschool vision screening appears to be more efficient with a device that directly detects strabismus and/or amblyopia. References: 1.

Jill C Rotruck Susan Day California Pacific Medical Center 2340 Clay Street San Francisco, CA 94115 Electronic Poster 125 Introduction: The Baylor Visual Acuity Tester (BVAT) is a common computer software program that presents randomized sequences of optotypes for visual acuity testing. Based on anecdotal concerns of multiple pediatric ophthalmologists, the purpose of this study was to evaluate if the sequence ‘F followed by U’ occurs more frequently than would be expected by chance. Methods: A single individual (JR) blinded to the purpose of the study obtained 6,750 serial samples of two-letter sequences from a single computer with BVAT software. The number of occurrences of each two-letter sequence were then totaled and analyzed. Results: The mean number of occurrences of each two-letter sequence was 18.2 with a SD of 5.5. The occurrence of the sequence ‘F followed by U’ was 18, which was not significantly different from the mean number of occurrences for all two-letter sequences. Two-letter sequences of repeat letters (i.e. AA, BB, etc.) were found to occur at significantly lower frequencies than average (Mean 4.2 with SD of 3.2 with P-value <0.001). Discussion: The number of occurrences of two-letter sequences randomly generated by BVAT software follows a normal distribution. Despite impressions of multiple pediatric ophthalmologists, the sequence ‘F followed by U’ was not found to occur more than would be expected by programming of other sequences. Significantly lower rates of repeat letter sequences suggest that it is possible to alter the BVAT algorithm to decrease the number of occurrences of unwanted sequences. Conclusion: While the sequence ‘F followed by U’ does not occur at a greater rate than chance, the BVAT algorithm could be altered to decrease its occurrence, thereby avoiding awkward moments during pediatric exams. Do we need to directly detect astigmatism when photoscreening for Amblyopia Risk Factors (ARFs)? David I Silbert MD Robert Arnold Family Eye Group Lancaster, Pennsylvania USA Introduction: The cost of smart phone platforms makes them highly desirable for use as vision-screening devices. Traditional vision screening uses two off-axis flashes in sequential photographs. We hypothesize that the vast majority of astigmatic eyes could be appropriately detected with a single flash and only one photograph simplifying image acquisition. Methods: 174 patients at 2 sites were enrolled prospectively. Children aged 12-72 months of age were consented and tested. The GoCheck Kids (Gobiquity Mobile Health, Inc) smartphone photorefraction measurements were compared to cycloplegic (gold standard) refraction using AAPOS ARF guidelines. Two photos were taken on each patient at 90 and 180 degrees. Analyses were performed for single-axis and double-axis photorefraction and compared. Results: 55/348 eyes of 30 patients identified with a cycloplegic astigmatism component above AAPOS ARF guidelines. 14/30 patients referred for cylinder only with the remaining 16 with refractive anomalies. Overall Single-axis sensitivity/specificity for AAPOS ARFs were 59%/83% respectively, while dual axis was 74%/82% respectively. Discussion: A single flash photoscreening system is effective for the detection of hypermetropia, myopia, and anisometropia. Although it will not directly detect astigmatism, astigmatism is indirectly detected and referred due to its association to other refractive anomalies. Elimination of need for a second photograph simplifies the use of a smartphone to detect ARFs. Conclusion: A single flash photoscreening system such as the Gobiquity mobile photoscreening device can be substituted for traditional two flash systems without sacrificing much sensitivity and specificity in astigmatism detection. 153 Electronic Poster 126 Electronic Poster 127 Efficacy of a vision-screening tool for birth to 3 early intervention programs. Roger Struble Jr. Ryan R House Linda M Lawrence MD Joyce E Trower PT University Of Kansas School of Medicine Kansas City, Kansas, ASA Introduction: This study aims to validate a screening tool to detect unsuspected ocular pathology in developmentally disabled children under age 3. There is a lack of a nationwide standardized vision-screening tool for children in birth to 3 in early intervention programs(1), and this inherently difficult-to-screen population is known to have a high risk for ocular pathology(2). Methods: 300 consecutive charts were reviewed from the health records at a birth to 3 early intervention program. Inclusion criteria were documented Kansas Department of Health and Environment vision screening exams performed by trained early interventionist, and full ophthalmologic evaluations. The patients were considered a passed exam if it was recorded on the chart and did not have any of the 23 risk factors listed by KDHE automatic referral guidelines(3). The ocular pathology status was determined after comprehensive ophthalmic examination, with the ophthalmologist blinded to the vision screen results. 216 met inclusion criteria. Results: The vision screen referred 85 of 216 children. The sensitivity, specificity, positive predictive value, negative predictive value, and negative likelihood ratio were respectively: 95.3% (90.8, 99.8), 57.25%, 59.1%, 94.9%, and 0.082. A Yates-Corrected Chi-Square test for goodness of fit gave an approximate p value of <0.001. Discussion: Information bias present with 65 incomplete charts and 19 children did not show for ophthalmologic exam. Conclusion: This inexpensive screening tool is effective as a standardized vision screen in early intervention programs for developmentally disabled children under age 3. References: 1.

The main goal of this study is to determine the accuracy of the plusoptiX referrals during 2013. Methods: In Oregon, 4077 vision screenings were completed by Head Start teachers and Elks Children’s Eye Clinic vision screening staff. Children were screened using a plusoptiX S12 with option 5 settings. IRB consent was obtained to follow up on referrals and to review exam chart notes. Results: Dilated eye exams were recommended for 1067 (26%) who were referred by the screening. A chart note review of 618 exams indicates that 54% of those referred received treatment, usually glasses. The primary treatment was glasses for 327 referrals. Of those treated with glasses, 225 received glasses after a dilated exam, 72 received glasses without the benefit of dilation, and 30 received glasses and it was unclear if they were dilated. Amblyopia was diagnosed by eye exam in 51 cases. The most common diagnosis was refractive error. Discussion: The program goal is to achieve high quality referrals. Astigmatism was the most common reason for over referrals. 42.4% of the plusoptiX astigmatism referrals did not require treatment. Conclusion: The plusoptiX S12 settings should be modified to minimize over referrals. In order to improve the quality of the referrals, the plusoptiX settings for astigmatism will be changed from 1.50D to 2.50D. 154 Notes 155 Notes 156 Workshop Schedule Thursday, March 26, 2015 2:45 PM - 4:00 PM Workshop #1 OMIC Workshop - The Risks and Benefits of Malpractice Litigation Paul Weber, JD; Denise R.

In order to successfully defend the lawsuit, ophthalmologists need to understand the legal process and the emotional challenges they will face. They also need to understand good risk management practices (documentation, informed consent) that will help them prevail in litigation. Target Audience: Ophthalmologists who specialize in pediatric ophthalmology and treat strabismus Current Practice: Ophthalmologists often experience shock and anger when sued for malpractice. While these emotions are natural they tend to be counterproductive in understanding the legal process and preparing an effective defense. Best Practice: This review of an actual lawsuit against an ophthalmologist that went to jury trial will describe specific steps to channel the strong emotions that arise in litigation into effectively working with the defense team to defend the lawsuit. Expected Outcomes: When faced with a malpractice claim, ophthalmologists will be able to identify positive steps they can take to successfully weather this stressful event. Format: Didactic and panel discussion Summary: This workshop will explore the personal, professional and legal issues that arise in malpractice litigation. Specifically, the faculty will discuss the importance of positive collaboration between the ophthalmologist, the defense attorney and the insurance company, and how this essential teamwork helps minimize the stress of litigation and increase the potential for a favorable outcome.

Graham E Quinn MD, MSCE, P Lloyd Hildebrand MD, Karen A Karp BSN, Ebenezer Daniel MBBS, MS, MPH, PhD, Kelly Wade MD, PhD, Alex R Kemper MD, MPH, MS, Daniel T. Weaver, MD Purpose/Relevance: To describe a telemedicine system for the detection of serious acute-phase ROP (e-ROP) and the implications of the study results. Target Audience: Ophthalmologists providing ROP detection and/or treatment Current Practice: The present strategy to identify infants needing treatment for retinopathy of prematurity (ROP) relies on repeated eye examinations of at-risk infants, few of whom require treatment. Best Practice: The best practice is to identify all premature infants at risk for serious ROP using non-physician personnel and targeting only those infants for examination by an ophthalmologist. Expected Outcomes: Retinal imaging by non-physicians with remote image interpretation by non-physicians may provide a more effective, accessible and efficient strategy than that currently in place. Format: Presentations, panel discussion with audience questions Summary: There is an urgent need to develop programs for detection of serious ROP that efficiently and effectively identify at-risk infants worldwide and that reduce the reliance on serial examinations by ophthalmologists. The results of the e-ROP study provide important information about the value of an ROP telemedicine system. Using a systematic approach with trained imagers and graders with quality management can decrease the burden of examinations on infants with sufficient identification of those infants that require more intensive eye care.

Is the Worth 4-dot Test Really Worth-Less? Lisa Rovick CO Natalie Kerr MD Anna Schweigert CO Raymond Areaux MD Jorie Jackson CO Aaron Miller MD Cindy Pritchard CO George Ellis MD Erika Acera CO David Granet MD David Silbert MD Purpose/Relevance: Sensory evaluation is an essential element in the preoperative evaluation of strabismic patients. The accurate selection, administration, and interpretation of sensory tests is crucial for optimizing the surgical plan. This workshop will illustrate how to effectively utilize preoperative sensory testing to improve surgical outcomes, including Lancaster red-green, synoptophore, Worth 4-Dot, stereo, and fusional/accommodative amplitudes.. Alternative means of testing will be presented for situations when the desired instrument or test is not available. Target Audience: Pediatric Ophthalmologists, Orthoptists, Researchers Current Practice: Surgeons do not always develop a surgical plan based on the knowledge of a patient’s sensory status. Best Practice: Practitioners will recognize the best sensory test for each clinical situation, and will administer and interpret the results correctly to help patients develop the best post- surgical alignment and binocularity. Expected Outcomes: Preoperative sensory testing allows the orthoptist and ophthalmologist to develop an appropriate surgical plan which optimizes patient binocularity and increases post-operative patient satisfaction. Format: Case-based illustrations with MD/CO co-presenters Summary: The best surgical plans incorporate accurate and effective preoperative sensory testing. This workshop will illustrate how and when these tests are best employed. References: Etezad Razavi M1, Najaran M, Moravvej R, Ansari Astaneh MR, Azimi A.

Workshop 4 Friday 7:00 - 8:15 am The tools of data analysis: matching the hammer to the nail Kristina Tarczy-Hornoch Gil Binenbaum Mays A El-Dairi Joost Felius Jing Jin Iris S Kassem Sudha Nallasamy Stacy L Pineles Jingyun Wang Purpose/Relevance: In this workshop, a panel of research committee members will present a friendly overview of the tools of data analysis, with the aim of helping the audience become more comfortable with approaching analysis of their own data, or understanding the data analysis in papers they read. Target Audience: Pediatric ophthalmologists who are not normally enamored of statistics. Current Practice: Clinicians do not always feel comfortable with statistical concepts and statistical jargon; yet reading or contributing to the evidence that forms the basis for our clinical practice requires a basic understanding of statistical analysis. Best Practice: Clinicians should feel at ease, not mystified, when reading the clinical research literature, and should be empowered to attempt straightforward data analysis of their own. Expected Outcomes: At the conclusion of this workshop, attendees will not be statisticians; they will be able to suggest appropriate statistical tools for different types of data analysis, and have a basic understanding of common analysis tools used in the clinical research literature. Format: Panel presentation, with didactic lectures and question/answer period. Summary: Components covered in this workshop include: a practical approach to basic statistics with a focus on the analysis tools commonly used in clinical trials and other clinical research; what tools are appropriate for what types of data; comparison of mean values; comparison of proportions; correlations; multivariate analysis; repeatability; sensitivity, specificity, and predictive values; power vector analysis of refractive error; numerical examples to promote empirical understanding (minimizing mathematical theory); common analysis pitfalls to avoid; a glossary of common and important statistical terms and concepts.

Presentation and Discussion of Cases in Pediatric Ophthalmology and Strabismus When the Unexpected Happened. What Happened and Why? How Can I Treat It? Prevent It? What I Learned From It? Workshop 5 Friday 7:00 - 8:15 am Tamara Wygnanski-Jaffe MD Alex V Levin MD Sharon F Freedman MD Joseph L Demer MD Itay Ben-Zion MD Gregg T Lueder MD Purpose/Relevance: The workshop is designed to share mistakes, unpredicted findings and outcomes with a discussion on preventive measures and management. Target Audience: Pediatric ophthalmologists, general ophthalmologists, and trainees. Current Practice: It’s much more difficult to present and discuss mistakes in history taking, diagnosis, imaging, surgical techniques, and unexpected surgical findings and complications than it is to present treatment successes. Sharing others experiences can teach us to expect, be aware, avoid and plan for the unexpected, if/when it should occur. Best Practice: This workshop allows participants to observe cases with unexpected outcomes with an explanation and discussion by the presenting clinician and discussion with the panel and the audience. Expected Outcomes: At the conclusion of the workshop the audience and the panel will have shared their experience with unexpected findings in common and rare clinical scenarios. It encourages the participants to expect the unexpected, seek and plan for it appropriately. Format: Members of the panel will present clinical and surgical cases in which they experienced an unusual finding due to a clinical anomaly or a clinical, imaging, or surgical mistake. Summary: Clinical and surgical cases with appropriate audio and visual material will be presented for discussion. These presentations will attempt to give the participants something to think about and take back to their respective practices. What Pediatric Ophthalmologists Need to Know about Clinical Quality Measurement, Registries, PQRS, and Measure Development Michael F Chiang Michael X Repka Christie Morse Robert Wiggins Kristina Tarczy-Hornoch Purpose/Relevance: We are rapidly moving from a reimbursement system that pays for volume (fee-for-service) to one that pays for value. This means that physicians are increasingly rated according to the costs and quality of their care. The Physician Quality Reporting System (PQRS) is expanding with the move to value-based purchasing. Meanwhile, large-scale registries (such as the AAO IRIS Registry) are providing unprecedented opportunities for access to clinical data that may be used for quality measurement. These trends are critical for pediatric ophthalmologists to understand. The purpose of this workshop is to discuss these topics, including ongoing work by AAO and AAPOS on developing quality measures for pediatric ophthalmology and strabismus. Target Audience: Pediatric ophthalmologists, administrators, researchers Current Practice: There are currently no PQRS quality measures directly related to pediatric ophthalmology. Lack of good quality measures may have negative financial implications for pediatric ophthalmologists under value-based payment models. Best Practice: AAPOS and AAO are working to develop quality measures relevant to pediatric ophthalmology practice. Expected Outcomes: Participants will understand the implications of these issues for quality improvement, how clinical documentation must be performed to support these outcome measures, and how this will affect reimbursement under value-based payment models. Format: 1) Panel presentations (45 minutes) 2) Open question and answer forum (30 minutes) Summary: This workshop will discuss: 1) Big data and registries for quality improvement. 2) Value-based purchasing and financial implications of PQRS and Meaningful Use for pediatric ophthalmologists. 3) Past and future work by AAO and AAPOS in these areas.

Melinda Rainey M.D. William O Young M.D. Purpose/Relevance: Initial difficulty in learning to read occurs in nearly 40% of students in the U.S. A number of different factors can cause difficulties in early reading including a true reading disability called dyslexia. Dyslexia is the most common learning disability, representing 80% of all learning disabilities and nearly 1 in 5 people in the U.S. have some degree of a learning disability. Most parents are unfamiliar with dyslexia and may believe that it is a vision-based disorder. Pediatric ophthalmologists need to be thoroughly informed about dyslexia, its controversial treatments, evidence-based educational treatments and resources available to be able to provide information and guidance to families of struggling readers. Target Audience: Pediatric Ophthalmologists and Certified Orthoptists Current Practice: Pediatric Ophthalmologists are often asked to evaluate children with reading or learning problems early in the process but may not have enough information to guide families. Best Practice: Pediatric ophthalmologists will be able to evaluate and manage children with reading and learning problems, become familiar with the AAPOS Learning Disabilities Package and guide families to resources and local educational experts. Expected Outcomes: The participant will gain a thorough understanding of the issues, controversies, evidence and resources on dyslexia to be better equipped to evaluate the patient who is experiencing reading difficulties, discuss dyslexia and provide guidance to our patients and their families. Format: Lecture format with question and answer session Summary: This workshop will give a comprehensive summary of the latest information on language acquisition, reading, dyslexia, the educational process, evidence-based educational treatments, the eye functions necessary to read and how to test for them in the ophthalmic exam. We will explore the controversial topics of vision therapy and colored lenses and filters. We will also provide information and guidance on what to tell parents using the AAPOS Learning Disabilities Package as an aid so that we can assist our patients in receiving the correct diagnoses and beneficial evidence-based therapies and accommodations.

Workshop 8 Friday 8:30 - 9:45 am The Impact of Brain Tumors on Vision and Ocular Motility Gena Heidary MD, PhD, Robert Avery, DO, Stacy Pineles, MD, Jane Edmond, MD Purpose/Relevance: Central nervous system (CNS) neoplasms comprise the most common solid tumors in childhood accounting for 27% of childhood cancer.1, 2 As the survival rate from childhood tumors continues to improve, visual morbidity from childhood cancer is significant. The direct effects of the tumor itself and tumor therapy including surgical resection, chemotherapy, and radiation therapy may impact visual function. The purpose of this workshop is to highlight important considerations regarding visual and ocular motility outcomes in those children suffering from CNS tumors. Target Audience: Pediatric ophthalmologists and pediatric neuro-ophthalmologists Current Practice: Ophthalmologists may not be familiar with the ophthalmic symptoms/signs suggestive of a CNS tumor, advances in our ability to screen for tumors of the visual pathways, and the role of the ophthalmologist in long term management of brain tumors that impact the visual system. Best Practice: Ophthalmologists should recognize the clinical signs that warrant urgent neuroimaging and be familiar with the natural history of tumors that affect the visual pathways in order to optimize clinical management. Expected Outcomes: The attendee will be empowered to recognize clinical signs suggestive of a CNS tumor and be familiar with the diagnostic evaluation. The clinician will become aware of evidence based visual and ocular motility outcomes for these patients thereby enhancing clinical management. Format: Panel with case presentations, didactic lectures and question/answer period Summary: The workshop will be divided into four topics: optic pathway gliomas (OPGs), craniopharyngiomas, dorsal midbrain tumors, and posterior fossa tumors. Each topic will be led by one of the authors with a case presentation followed by a didactic talk. The OPG section will provide insight into the natural history and treatment outcomes of these tumors as well as utility of handheld OCT. The craniopharyngioma and posterior fossa sections will provide data regarding visual outcomes and ocular motility outcomes. The dorsal midbrain tumors section will be focused on the tumor types that affect the dorsal midbrain and the afferent and efferent dysfunction associated with these tumors. References: 1.

Secrets to Solve Pediatric Ophthalmology Case Mysteries Aparna Ramasubramanian Carol L Shields Alex V Levin Bruce Schnall Jerry A Shields Workshop 9 Friday 8:30 - 9:45 am Purpose/Relevance: The specialty of pediatric ophthalmology poses a unique challenge in that there are a multitude of diseases. Some can masquerade and have atypical presentations. The exam is often limited and the diagnosis may need to be determined with few clinical signs. This workshop will provide rapid diagnostic and management tips to crack some of the mysteries of pediatric ophthalmology. Target Audience: Pediatric Ophthalmologists & General Ophthalmologists Current Practice: Pediatric ophthalmologists often encounter diagnostic dilemmas in the setting of atypical clinical presentations or rare clinical diseases. Clinical acumen is essential and there are several ancillary tests that can add critical information in each particular scenario. Best Practice: Recognition of key clinical features and ordering the right diagnostic test that can clinche the diagnosis. Appropriate treatment decisions can make an immense difference in the final outcome of the child. Expected Outcomes: At the conclusion of this presentation, attendees would be able to recognize key clinical features of various pediatric ophthalmology conditions. The workshop would aid in ordering the appropriate diagnostic test and would give management tips to the audience. Format: Case Presentation Summary: With the use of multiple split second cases an overview of important diagnostic pearls in pediatric ophthalmology will be provided. The range of the workshop would be from external diseases to glaucoma, systemic syndromes and tumors. References: Shields CL, Schoenfeld E, Kocher K, Shukla SY, Kaliki S, Shields JA.

Neuro-ophthalmic Manifestations of Systemic Disease, Part 2 Jane C Edmond MD R Michael Siatkowski MD Purpose/Relevance: The afferent and efferent visual systems may be affected by a wide range of systemic diseases: neurologic, hematologic, inflammatory, infectious, toxic/adverse drug reactions, paraneoplastic and genetic. In a case presentation style, specific conditions will be presented and discussed. Examples are neuro-degenerative and demyelinating diesases, acquired Horner syndrome, nystagmus and cranial nerve palsies. Target Audience: Comprehensive pediatric ophthalmologists Current Practice: Pediatric ophthalmologists, especially those who are performing hospital consultations or who practice in tertiary care facilities, often encounter children with multi-system disease. A wide variety of systemic disorders cause neuroophthalmic complications, some that may be sight threatening if not recognized and treated. This symposium with present some of the more common systemic diseases that lead to neuro-ophthalmic complications in the pediatric population Best Practice: Pediatric ophthalmologists may not be aware of the ophthalmic complications of common systemic disease states, especially when they are neuroophthalmic in nature. Expected Outcomes: Participants will be better able to identify neuro-ophthalmic complications of certain systemic diseases and provide a prompt diagnosis and treatment, with may impact the visual and overall outcome of the patient. Format: Case presentations with panel discussion, with open question and answer forum for the audience. Summary: Summarize material to be presented at the workshop : neuro-degenerative and demyelinating diesases, acquired Horner syndrome, nystagmus and cranial nerve palsies.

Target Audience: Pediatric Ophthalmologist, Pediatricians, Orthoptists, and others involved in the treatment of children. Current Practice: Pediatric ophthalmologists need information about what exists in the real world for their patients with low vision and/or blindness. They may not understand the importance of their “eye report” for the individual education plan (IEP) that legally governs the child’s education. Communication with the educational specialist at home and school is not commonplace from the medical profession. Best Practice: Referrals to vision rehabilitation and intervention services should be made within 30 days of diagnosis. Accurate and understandable documentation and communication is crucial to ensure the educational team can provide the proper resources in the home or classroom for the child with visual impairment. Pediatric ophthalmologists and their eye care teams need better understanding of how their evaluations and recommendations translate into the educational setting. Expected Outcomes: Expected outcomes are earlier referrals from medical to educational resources, better understanding of educational interventions that exist for children with low vision and blindness, including those with multiple disabilities, and the importance of the IFSP (Individual Family Service plan (for birth to 3) or IEP (Individual Educational Plan for 3-22yo), documents that direct the child’s educational interventions. Format: Presenting ophthalmologists will team with educational experts. Case presentation will demonstrate proper assessments and interventions with interactive discussion between the ophthalmologist and educators: 1. Introduction of the history of pediatric low vision interventions 2. Early intervention 3. School age 4. Teenage and transition to work 5. Open questions and answers Summary: Low vision and blindness needs a continuum of care between medical and educational professionals. References: 1.

Workshop 12 Friday 10:30 - 11:45 am Apt Lecture Workshop Science, Pseudoscience, and the law in AHT Alex V Levin MD, MHSc, FRCSC Brian J Forbes Sr Gil Binenbaum Steve E Rubin Purpose/Relevance: Ophthalmologic examination is an important component in the evaluation of the young child whose injuries are suspicious for child abuse. Abusive head trauma (AHT) refers to the repetitive violent acceleration-deceleration head and neck movements with resultant injuries in children typically younger than 3 years of age. It is generally characterized by fractures, intracranial hemorrhages, and/or intraocular hemorrhages, with retinal hemorrhages being the most characteristic ocular finding. Target Audience: All doctors, although focusing on ophthalmologists, evaluating children in the setting of possible abuse and those expected to appear in court or be deposed to report their medical findings. Current Practice: Recent publications have disputed some of the long held beliefs associated with AHT, and pediatric ophthalmologists are increasingly encountering questionable proposed alternative diagnoses and a controversy over the diagnosis of AHT. We will present and discuss these theories and evaluate examples of recent literature consistent with or challenging previous beliefs about the interpretation of retinal findings. Best Practice: It is the hope of all health care providers to do what is best for both the child and the family in cases of AHT but navigating the medical, legal and judicial systems can be out of our comfort zone as physicians. This workshop is designed to help participants gain comfort with the process. Expected Outcomes: This workshop is designed to help participants gain comfort in navigating the medical, legal and judicial systems in cases of AHT by familarizing them with the current AHT literature and means by which to navigate the legal system. Format: A didactic presentation of characteristic ophthalmic aspects of AHT, ‘new science’ and ‘new pseudoscience’, followed by a talk on the legal aspects of AHT within the contexts of medical certainty, reasonableness and practical advice for the legal area will be presented. Finally, time will be reserved for the audience to submit cases for discussion. Summary: Recent publications have disputed some of the long held beliefs associated with Shaken Baby Syndrome/Abusive Head Trauma, and pediatric ophthalmologists are increasingly encountering questionable proposed alternative diagnoses and a controversy over the diagnosis of abusive head trauma. We will present and discuss these theories and evaluate examples of recent literature consistent with or challenging previous beliefs about the interpretation of retinal findings. References: 1.

Khan MD; Elias I Traboulsi MD Purpose/Relevance: The phenotype of bilateral congenital or juvenile cataract is generally non-specific. However, there are exceptions. These include treatable disease which the pediatric ophthalmologist is uniquely able to recognize early. Target Audience: Pediatric ophthalmologists. Current Practice: Pediatric ophthalmologists often manage pediatric cataracts with minimal or no diagnostic evaluation. Best Practice: Certain types of cataract (phenotypes) should raise suspicion for particular underlying genetic/metabolic conditions, the early diagnosis of which is optimal for the child. Expected Outcomes: Improved diagnosis and decreased patient morbidity. Format: Didactic lecture, case presentation, open question and answer forum, panel discussion. Summary: Certain forms of bilateral pediatric cataracts are characteristic of specific underlying gene mutations and metabolic disorders, some of which are amenable to early treatment. The pediatric ophthalmologist is uniquely able to recognize these conditions early. Several recognizable phenotype-genotype correlations for pediatric cataracts will be discussed, with emphasis on treatable conditions. References: 1. Trumler AA.

Simultaneously attaining these goals for a business that is heavily regulated, such as medicine, can be challenging. One way to improve efficiency and productivity is to hire a physician extender, such as an orthoptist. But for this to be effective, revenue generated by the hiring of additional personnel must well outweigh the increased overhead. Target Audience: This workshop is directed to pediatric ophthalmologists and administrators with an interest in incorporating an orthoptist into their practice, or for those who already employ orthoptists, and are seeking to boost productivity and practice income. Current Practice: Currently in many areas of the country, there is limited access to a pediatric ophthalmologist. Pediatric ophthalmologists may find themselves sacrificing quality of care in order to meet the high demand for their services. Best Practice: When physician extenders, such as an orthoptist, are utilized appropriately one can increase access of care to the pediatric ophthalmologist without compromising quality of care. Expected Outcomes: Panelists will present data on the value of an orthoptist as an income generator, and as a skilled, well-educated provider, as well as how to hire an orthoptist and create a thriving orthoptic clinic within a practice. Format: Panel discussion that will feature the Chair of the AACO Practice Management Committee, practice managers for both a private group practice and an academic institution, pediatric ophthalmologists who successfully employ orthoptists and other technical personnel, and an Orthoptist Program Director and past Chair of the AACO Education Committee. Summary: An orthoptist can be a valuable asset to both academic and private practices, who will stimulate growth, enhance the quality of care, and increase profits.

Currently there are no approved pharmacologic treatments, but current phase III subretinal gene replacement clinical trials show potential for treatment availability in the near future. There are potentially many patients in the U.S. with RPE65 mutations that do not have genetic testing confirmation. Pediatric ophthalmologists are often the first to make a diagnosis of LCA or RP, and are therefore in a unique position to educate patients and parents about current clinical trials and potential future treatments. Target Audience: Pediatric ophthalmologists, orthoptists and inherited retinal degeneration specialists Current Practice: Genetic testing for inherited retinal degeneration (IRD) has not always been viewed as a necessary component of patient care. Since historically these conditions were untreatable, eye care professionals may not have been trained to educate patients about genetic testing, clinical trials and possible future treatments. Best Practice: Gene replacement strategies have made major advances toward a treatment of RPE65 related disease as well as other retinal disorders. The standard of care should include molecular genetic testing, genetic counseling and education about clinical trials and future treatment options, enabling identification of patients who may benefit from gene-based therapies. Expected Outcomes: 1. To be knowledgeable about ordering appropriate genetic tests. 2. Be able to discuss current gene therapy trials, the impact for patients and future availability of treatment. Format: Didactic lecture, open question and answer forum Summary: 1. Overview of RPE65 gene therapy trials, and update on which disorders have treatment trials underway. 2. Outline of the procedures for obtaining genetic testing. 3. Summary of gene therapy and pharmacologic therapy clinical trials for other IRDs. 4. Summary of what animal models are teaching us about subretinal gene therapy. References: 1. Zanolli, Mario T., et al, Curr Opin Ophthalmol., 2014 Lancet. 2009 168 2. Bennett, J., et al., Sci Transl Med. 2012 3. Maguire, AM., et al., Does this child have glaucoma or something else? Applying newer technologies to the diagnosis and management of pediatric glaucoma. Sharon F Freedman MD Allen D Beck MD Alex V Levin MD Workshop 17 Friday 1:15 - 2:30 pm Purpose/Relevance: The workshop is designed to highlight the sometimes challenging clinical entity of the ‘glaucoma suspect’, with emphasis on newer ophthalmic technologies and how they may assist in our diagnostic evaluation of these cases. Medication update and pearls for use in children will be included. Target Audience: Pediatric ophthalmologists, pediatric-interested comprehensive ophthalmologists, and trainees. Current Practice: Although childhood glaucoma cases often present with clear objective signs that make its diagnosis (though not necessarily its successful treatment!) rather straightforward, there are other cases where optic nerve or other features raise the specter of ‘glaucoma suspect’. The stakes are high, since missing true glaucoma may lead to irreversible optic nerve/vision damage. On the other hand, labeling a child with glaucoma who has ‘something else’ may involve needless worry, unnecessary testing, and even long-term interventions that have risks. Discussing challenging cases where glaucoma suspicion arises, and examining the selective use of newer technologies and other clinical clues, may assist the clinician in dealing with cases of possible childhood glaucoma. New glaucoma medications and combinations keep ‘popping up’, often without clear guidelines for their optimal use/warnings in children. Best Practice: Ideally, the practicing pediatric ophthalmologist and pediatric-oriented comprehensive ophthalmologist, should employ clinical and family history, clinical examination of the child’s ocular features (anterior segment and angle, intraocular pressure, refraction, and optic nerve), together with technology (when appropriate to include tonometry, pachymetry, visual fields, and retinal nerve fiber layer analysis, optic nerve head photography), to assess the likelihood that a particular child’s eye has true or suspected glaucoma, or ‘something else’ (concerning or reassuring). A management plan should follow based upon the level of risk. The clinician should be able to devise a medication regimen (when indicated) that maximizes effect and minimizes risk to the child. Expected Outcomes: At the conclusion of this workshop, the audience will have seen examples of children suspected of glaucoma based upon optic nerve head abnormalities, elevated intraocular pressure, and other ocular features. They will also have seen cases presenting as possible glaucoma that turned out to be ‘non-glaucoma’ entities. They should have gained an understanding of when to use newer tonometers, how to interpret corneal pachymetry findings, as well as imaging such as optical coherence tomography as tools in the diagnosis of these ‘glaucoma suspects’. They should have gleaned several strategies for managing ‘suspects’ at various degrees of “suspicion” for true glaucoma in their practices, as well as criteria that might prompt referral or treatment. They should be familiar with current medications for glaucoma and tips for their safe use in children who need them. Format: Members of the panel will present cases where glaucoma was suspected, and highlight their diagnostic strategy, highlighting technology when appropriate to the case diagnosis or management. Attendee questions and comments will be encouraged. Summary: This workshop will examine the features that bring children in as ‘glaucoma suspects’, and will include cases of ‘real’ glaucoma, legitimate ‘suspects’, as well as those who turned out to have “something else” that was either benign or worrisome. We will emphasis newer ophthalmic technologies (including tonometry, optical coherence tomography, visual fields and ultrasound), as well as good old clinical acumen, and how they may assist in our diagnostic evaluation of these cases. We will include a medication update and pearls for medication use in children. References: World Glaucoma Association, Childhood Glaucoma, Consensus series 9, 2013.

Adult Strabismus Workshop David B Granet MD, David L Guyton MD, Edward G Buckley MD, Steven M Archer MD, David Stager, Sr MD, Forrest J Ellis MD, Lionel Kowal MD, David Hunter MD Purpose/Relevance: The surgical treatment of the adult with strabismus comprises a significant portion of the clinical and surgical volume of many pediatric ophthalmologists. This workshop is designed to educate attendees regarding surgical treatment of adults with strabismus. Target Audience: Pediatric ophthalmologists & orthoptists interested in evaluating and treating adults with strabismus. Current Practice: Pediatric ophthalmologists are often intimidated by adults with complicated forms of strabismus. A variety of challenges often deter surgical intervention including fear of post-operative diplopia and a lack of confidence in managing torsion and re-operations. Best Practice: Clinicians will gain a more thorough understanding of the surgical approaches and techniques which yield better outcomes in adults with strabismus. Expected Outcomes: At the conclusion of the workshop, attendees will have a better understanding of effective strategies for managing adults with complicated forms of strabismus. Format: The workshop will include discussions and presentations by a panel of experts. In addition, time for audience participation with questions of the panelists is planned. Use of video for teaching will be included. Throughout the discussions, pertinent scientific literature will be presented and reviewed. Summary: Topics will include challenging cases of adults with complicated forms of strabismus; including re-operation strategies, management of torsion and incomitant deviations, and correction after other ocular surgery or disease, as well as tips, pearls, and advice from surgeons with years of experience.

Williams MD, Patrick Hynes Purpose/Relevance: This symposium will (1) present information about the myriad of external forces that may negatively impact the eye health of our patients, (2) provide attendees with social media tools for communication with patients and (3) motivate attendees to integrate patient advocacy activities into our professional life. Target Audience: This symposium is targeted to pediatric and general ophthalmologists, orthoptists, and others engaged in the work of improving eye care for our patients. Current Practice: Legislative and regulatory policies can negatively impact the eye health of our patients. Ophthalmologists historically have received little formal education about such external forces and know little of the tools, including social media and advocacy, that can be utilized to improve eyecare for our patients. Best Practice: Ophthalmologists spend years of training to develop a strong knowledge base and excellent clinical skills. Personal professional attention must also be directed at system-wide issues that impact the eye health of our patients and consumer perception of eye health options. Expected Outcomes: It is hoped that with an increase in knowledge and awareness of the many different types of advocacy activities available, in addition to increased skills in social media communication, attendees will become personally engaged in social media communication and advocacy on behalf of our patients. Format: The format for the symposium will be panel discussion, highlighted entertaining presentation, with open Q&A Summary: Our ability to take care of our patients is influenced by many forces outside of medicine on the national, state and local level. Techniques for effective social media communication, applicable to many types of relationships, will be discussed. Through education, with a focus on social media, and humorous entertainment, the AAPOS Legislative Committee hopes to inspire attendees to include advocacy activity as an integral part of his/her professional life.

David I Silbert MD (Moderator); Sean Donahue MD; Alan Greene MD; Deborah Alcorn MD; Robert Arnold MD Workshop 25 Saturday 7:00 - 8:15 am Purpose/Relevance: Traditional vision screening utilizes visual acuity charts, requiring a subjective response from a child. This can be especially challenging for non-verbal, preverbal, and early verbal children and can lead to over-referral of young children for confirmatory examinations with significant cost implications. This has led to the wide use of photoscreeners. Target Audience: Pediatric Ophthalmologists, Orthoptists and Ophthalmic Technicians Current Practice: Screening for ARF’s are performed in the medical home, as well as the school setting utilizing both objective and subjective tests including acuity testing and photoscreening. Best Practice: This seminar will provide evidence-based data and will familiarize participants with the various commercially available photoscreeners. The literature will be reviewed looking at the sensitivity and specificity of the devices for detection of AAPOS ARF’s and comparing this to subjective acuity testing, specifically looking at the detection of AAPOS Amblyopia Referral Criteria (ARF’s) and comparing as compared to subjective acuity testing. Expected Outcomes: Improvement in detection of ARF’s and effective treatment of target population Format: The seminar will address: 1) AAPOS, AAO, and AAP positions on photoscreening, AAPOS guidelines, USPF task force recommendations and the recent National Expert Panel recommendations 2) Positive Predictive Value of acuity testing and photoscreening 3) Evidence-based look at sensitivity and specificity of photoscreeners 4) A pediatrician’s perspective on acuity testing and photoscreening including, challenges of vision screening in the primary care setting, understanding impact of sensitivity and specificity, and impact of over-referral to ophthalmology 5) Evidence of benefit of early detection and treatment of amblyopia and communication with referring pediatricians to improve outcomes 6) Partnership between primary care and pediatric ophthalmology, to enhance outcomes, the Alaska experience.

Fiscal Benchmarking Workshop- Data From CY 2013, AAPOS Socioeconomic Committee Deborah S Lenahan MD Nils Mungan MD Eric Lichtenstein MD Bob Wiggins MD John Bishop MD Mike Bartiss MD, OD Purpose/Relevance: The purpose of this presentation is to present financial data gathered by a survey of AAPOS members. This will be the fifth consecutive year that key metrics for a successful pediatric ophthalmology practice have been evaluated and discussed. Each year, the survey continues to be refined. This year will debut a new survey platform intended to minimize unreliable responses and diminish loss of data due to incomplete surveys. Target Audience: The target audience is pediatric ophthalmologists and their practices. Current Practice: Financial benchmarks have not been available for pediatric ophthalmology until the advent of the SEC Fiscal Benchmarks Project in 2010. Best Practice: The ongoing survey discussed at this workshop allows AAPOS members to establish norms specific to pediatric ophthalmology, thus enabling participants to identify potential problem areas in their practice, whether private or academic. Expected Outcomes: At the conclusion of the session, the attendees will be able to understand key financial metrics in their practices and have norms available for comparison. Additionally, they will gain a better understanding of how practice patterns can be modified to enhance practice profitability. Format: Panel discussion/open question and answer forum. Summary: The data from the just completed CY 2013 survey will be presented. This information will be discussed, with a panel discussion of each of the benchmarks and questions from the audience.

Ophthalmic Coding Series Essential Topics and Pediatric/ Video Demonstrations of Signs, Diseases, and Complex Surgical Procedures in Pediatric Ophthalmology and Strabismus Federico G Velez MD Evelyn A Paysse MD Jonathan M Holmes MD Michael X Repka MD Bibiana Jin Reiser MD Ramesh Kekunnaya MD Purpose/Relevance: Video demonstration of unusual and complex signs, diseases, and surgical procedures in pediatric ophthalmology and strabismus Target Audience: Pediatric Ophthalmologist and Strabismologist, Orthoptists, and Training Ophthalmologist. Current Practice: Some signs and surgical procedures described in textbooks represent a challenge because some conditions are rarely seen in clinics and some surgical procedures are almost exclusively performed at tertiary referring centers. Best Practice: This workshop allows to see videos of rare signs and surgical procedures, with an explanation by the ophthalmologist who recorded it and a discussion with the panelist and the audience. Expected Outcomes: Increase the level of awareness and confidence when performing an examination, making a diagnosis and planning treatment. Format: Six experienced pediatric ophthalmologist and strabismologist will present and discuss videos of signs, diseases, and surgical procedures. Panelist will discuss differential diagnosis and potential treatment options. Audience participation is encouraged. Summary: Demonstration of classical or rare signs, diseases, surgical procedures using high quality video presentations. 174 Difficult Non-Strabismus Problems in Pediatric Ophthalmology Elias I Traboulsi MD, MEd Arlene V Drack MD F. James Ellis MD Mohamad S Jaafar MD Virginia Utz, MD Deborah Vanderveen MD Workshop 29 Sunday 9:00 - 10:00 am Purpose/Relevance: Sharing the difficulties in making the diagnosis and managing rare and atypical cases allows practitioners to benefit from each other’s experience and to discuss alternative evaluation and treatment plans. The presentation of several such cases to a broad audience of interested individuals allows the appropriate ditribution of such teaching cases. Target Audience: Pediatric ophthalmologists , orthoptists, vision scientists and trainees Current Practice: While many pediatric ophthalmologists elect to manage difficult cases, others refer such cases to other pediatric ophthalmologists or subspecialists with advanced or more extensive experience in the particular area of disease or management that the patient needs. Best Practice: While many difficult diagnostic cases can be addressed via telephone or email communications between the primary treating physician and the expert, others need to visit one or more subspecialists before a final diagnosis is reached and a treatment plan is firmly established. Group presentation of cases in some instances is necessary with the participation of several advanced practitioners, sometimes from specialities outside of ophthalmology. Expected Outcomes: At the conclusion of the workshop the audience and the panel will have shared their experiences and strategies for the diagnosis and management of a few challenging cases. The practitioner in the audience is expected to gain new insights into the clinical reasoning behind each diagnosis and the purpose of any intervention. Format: Each panelist will present one case and invite the other panelists to discuss their approaches to diagnosis and treatment. The audience will participate by asking questions or providing personal insights. Summary: Case-based learning experience involving 5 challenging pediatric ophthlalmology non-strabismus cases Difficult Problems: Strabismus Sean P Donahue MD, PhD Ed Buckley MD Stacy Pineles MD Oscar Cruz MD Linda Dagi MD Marc Greenberg MD Purpose/Relevance: The most common ICD-9 codes used by pediatric ophthalmologists concerned strabismus. Patients that present with straight-forward unoperated strabismus do not present a challenge to most pediatric ophthalmologists. However, patients may also present with very complex strabismus that pose diagnostic and therapeutic challenges: strabismus secondary to brain injury, brain tumors, cranial nerve palsies, orbital disease or anomalies, and status post multiple extraocular muscle surgeries. This workshop will specifically deal with rarer and more atypical presentations of strabismus that present a knowledge gap to the practicing pediatric ophthalmologist. Target Audience: Pediatric ophthalmologists in practice and fellowship training, Orthoptists, Opthalmology Residents Current Practice: They are reading medical journals, attending CME meetings, talking among their colleagues. Best Practice: Participants will gain new perspective from the review of cases by pediatric ophthalmologist experts who deal with complex strabismus. New insights will inform clinical and surgical approach when confronted complex strabismus. Expected Outcomes: At the conclusion of the symposium the attendees will have been taught new skills and refine previous skills in the diagnosis of complex and diverse strabismus conditions, the salient exam features to perform, tests to order, and new surgical skills in the treatment of complicated strabismus Format: The symposium will consist of expert panel discussion and subsequent open question and answer forum with the audience’s participation. Actual patient vignettes will be presented. The presenter will provide a differential diagnosis, a treatment plan, shedding insight on the disease process, the etiology of the strabismus, and the rationale behind the treatment, and treatment outcome. Also discussed will be the potential reasons for the treatment success or failure Summary: The panel participants are all internationally recognized experts in the field of strabismus and strabismus surgery. They will each present a difficult case that will be discussed by the other experts, and the results of the treatment will be presented and discussed. Approximately 6 cases will be presented.
