Basement membranes serve as the foundation on which the epithelial cells, which absorb nutrients from tears, anchor and organize themselves. When the basement membrane develops abnormality, the epithelial cells cannot properly adhere to it. This in turn, causes recurrent epithelial erosions, in which the epithelium's rises slightly, exposing a small gap between the outermost layer and the rest of the cornea. Epithelial erosions can be a chronic problem, and may alter the cornea's normal curvature, causing periodic blurred vision, also moderate to severe pain that lasting several days. Generally, pain will be worse on awakening in the morning, and other symptoms include sensitivity to light, excessive tearing and foreign body sensation. Most common, it occurs in both eyes and usually affects adults ages 40-70, although can develop earlier. Typically, EBMD will flare up occasionally for a few years and then go away on its own, with no lasting loss of vision. Prescribe lubricating eye drops and ointments (Muro-128 gtts & ung “Sodium-chloride 5%”), control the pain, and patch the eye, w/tx. these erosions usually heal within 3-days, although periodic pain may occur for several weeks. Other treatments includes; therapeutic soft contact lenses, anterior corneal punctures to allow better adherence of cells, corneal scraping to remove eroded areas and allow regeneration of epithelial tissue, also use of the excimer laser to remove surface irregularities. 63 Fuchs' Dystrophy: D O N O T PR IN T O R C O PY ,V IE W O N LY Is a slow progressing disease that affects both eyes equally (all-dystrophies), is more common in women, and affects vision in adults age 50-60, (although can see early-sign in 30-40 years old Pt.). Fuchs' dystrophy occurs when endothelial cells gradually deteriorate without any apparent reason. As more endothelial cells are lost over the years, the endothelium becomes less efficient at pumping water out of the stroma. This causes the cornea to swell and distort vision. Eventually, the epithelium also takes on water, resulting in pain and severe visual impairment. Epithelial swelling damages vision by changing the cornea's normal curvature, and causing a sight-impairing haze to appear in the tissue. Epithelial swelling will also produce tiny blisters on the corneal surface. When these blisters burst, they are extremely painful. At first, a person with Fuchs' dystrophy will awaken with blurred vision that will gradually clear during the day. This occurs because the cornea is thicker in the morning; it retains fluids during sleep that evaporate in the tear film while we are awake. As the disease worsens, this swelling will remain constant and reduce vision throughout the day. Try to reduce the swelling with ointments, drops (Muro-128 gtts & ung). Also, may instruct the patient to use a hair dryer, held at arm's length, directed across the face, to dry out the epithelial blisters (can be done 2-3 times a day). Corneal transplant has a good short term success rate, but long term survival proven to be a problem. 64 Lattice Dystrophy: D O N O T PR IN T O R C O PY ,V IE W O N LY Is an accumulation of amyloid deposits or abnormal protein fibers throughout the middle and anterior of stroma. Slit lamp observation shows these deposits in the stroma as, clear comma shaped overlapping dots, and branching filaments. Over time, the lattice lines will grow opaque and involve more of the stroma, and gradually converge, giving the cornea a cloudiness that may also reduce vision. In some cases these protein fibers can accumulate under the epithelium and cause epithelial erosion (known as recurrent epithelial erosion). This results in temporary vision problem (due to curvature alteration) and severe pain (due to nerve ending exposures) even with blinking. Prescribe ointments and drops (Muro-128 gtts & ung), reduce the friction on the eroded cornea, and sometimes eye patch, to immobilize the eyelids. These erosions usually heal within 3-days, although occasional pain may occur for the next 6-8 weeks. Although lattice dystrophy can occur at any time in life, but usually arises in children age 2-7, and by age 40, scarring under epithelium results in haze on the cornea that can greatly obscure vision. Recurrence of the disease can arise in the donor corneal transplant in as little as 3-years, (in 50% of transplant Pt. between 2 to 26 years after Sx.), and may require a 2nd transplant. Excimer laser has shown good response in patients, (removes surface irregularities). 65 Keratoconus: IN T O R C O PY ,V IE W O N LY It is more prevalent in teenagers and adults in their 20‟s. Keratoconus arises when the middle of the cornea thins and gradually bulges outward, forming a rounded cone shape. This curvature change produces, moderate to severe astigmatism (distortion) and blurriness. It may also cause swelling and scarring of the tissue. It is about 7% inherited and Down-syndrome could be one of the systemic factors. Usually affects both eyes, and specially fitted contact lenses (RGP) are the vision correction of the choice. In most-cases, the cornea will stabilize after a few years without ever causing severe vision problems. But in about 10-20% of patients, corneal transplant is needed due to scar, and this operation is successful in 90% of patients, with 80% of them having 20/40 or better vision after the Sx.

Diabetes O N O T PR IN T O R C O PY ,V IE W O N LY Insulin: glucose is a sugar-metabolized by cell to create the energy necessary for biological-processes. Insulin is a hormone produced by the islet-cells in the pancreas, it promotes the transport of glucose from the blood across the cell-membrane into muscle and fat cells where it is converted-into glycogen (a form of glucose that can be stored in the liver), insulin also ↑both the rate of synthesis of proteins from amino-acids and the cellular-uptake of amino-acids certain ions and fats. Consequently, insulin ↓blood-glucose-concentrations. *Glucagon is a hormone that is also produced in the pancreas but acts to ↑blood-glucose level by promoting the metabolism of glycogen in the liver into glucose.

Furthermore glucose in excess have vascular-endothelium effects, resulting in weak, leaky-capillaries which lead to less blood-perfusion to tissues. Diabetic-nephropathy, results from the thickening of the capillary basement-membrane in the glomerulus of the kidney resulting in a poor-filtration. The result is abnormal-excretion of larger macro-molecules such as proteins. As the disease progresses, frank renal-failure and hypertension occurs requiring kidney-transplantation.

Diabetes O PY ,V IE W O N LY NIDDM, type-II: Pathophysiology processes of this diabetes-mellitus has adult onset, and milder forms of hyper-glycemic conditions (90% of cases). Ample amount of insulin is produced by the pancreas, but the insulin is ineffective at transporting glucose across muscle and fat cell membranes. O N O T PR IN T O R C There are two sub-types: “non-obese” form occurs when the insulin that is produced is defective in promoting glucose transport across cell-membranes. In the most common form of diabetes, the “obese” form of NIDDM, the insulin produced is normal in both amount and its effectivity. The disease lie at the level of the insulin-receptors on the outside-surface of muscle and fat cells that do not-respond properly to the effect of insulin, (cause unknown, speculation that over-eating leads to desensitizing “perhapsreversible” of target-cell insulin-receptors). Glucose-build in the blood-stream causing to further ↑insulin being-produced. D 115 IDDM, type-I: damage (possibly from prior infection by a virus or an exogenous-toxin) to the insulin-producing cells of the pancreas causes an insufficient amount of insulin to be produced, consistently there is not sufficient ability to move the glucose across cell membrane into muscle and fat cells, and blood-glucose levels increases, (10% of all cases, usually diagnosed in children, certain genetic Oral hypoglycemic drugs (category of sulfonyl-ureas), are first-line choice for NIDDM patients, they act by ↑activity of insulin-producing cells in the pancreas, (most effective in non-obese NIDDM, but used in all types). **first-generation: -chlorpromadine (diabenese) 100 - 250 mg qd, -tolbutamide (orinase) 500mg bid, -tolazamide (tolinase)100-500 mg qd-bid **second-generation; more-powerful, and commonly prescribed NIDDM): -Glipizide(glucotrol)5-15mg qd, -Glyburide(diabeta, micronase)2.5-10mg qd *Insulin (concentration of 100 units/ml “u100” are dispensed in 10ml vials) sub-cutaneous injection, for IDDM “and NIDDM who poorly controlled by oral-medicines”.

Microvascular leakage fallows the impairment of the structural integrity of retinal capillaries heralded by the development of microaneurysms. Microaneurysms may either become thrombosed or may leak serum components into the surroundings retina, “microaneurysms may leak-fluid and can sometimes be at the center of a ring of exudates”. Retinal-edema, lipidexudates and dot-blot intraretinal hemorrhages are the result of such break-down of the blood-retinal barrier. Capillary nonperfusion, on the other hand, results in the formation of arteriovenous-shunts known as intra-retinal micro-vascular -abnormalities (IRMA) - [Unlike extraretinal neovascularization, IRMA do not-leak on fluorescein angiography (FA)]. Elaboration of vascular-endothelial growth-factor (VEGF) form hypoxic-retina in areas of capillary-nonperfusion results in the development of extraretinal-neovascularization. These new-vessels extend from the retina-into the vitreous. D 117 Extraretinal-neovascularization is associated with vitreous-hemorrhage and production of fibrovascular-traction. These new-vessels may arise from the optic disc (NVD) or elsewhere in the retinal-periphery (NVE). Such neo-vascularization and its associated fibrous-component may spontaneously involute, or be complicated by vitreous-hemorrhage or traction retinal-detachment. Neovascularization may be easily seen on fluorescein-angiogram by the profuse-leakage of dye from these new vessels, since they lack the tight-endothelial junctions of the retinal-vasculature. Impaired axoplasmic-flow in areas of retinal-hypoxia result in cotton-wool spots. Until the late-stages of its development, diabetic-retinopathy remain largely asymptomatic. For this reason uniform-classification and careful screening of diabetics is required in order to identify those patient who would benefit from timely-treatment. Diabetic-retinopathy is Classified into two main-groups: Nonproliferative and Proliferative, based on the presence of neovascularization. Macular-edema may be associated with either-group. Areas suspicious for neovascularization may be confirmed by their marked leakage of fluorescein-dye by angiography. D O N O T PR IN T O R C O PY ,V IE W O N LY - 118 Nonproliferative diabetic retinopathy (NPDR) can be further divided into mild-NPDR, moderate-NPDR, and severe-NPDR in an effort to predict which eyes are at higher risk of developing-proliferative retinopathy. Mild-NPDR describes eyes with scattered-hemorrhages and microaneurysms. Moderate-NPDR contains hemorrhages and microaneurysms and mild-degrees of soft-exudates, venous-beading and IRMA. Severe-NPDR is defined by the presence of venous-beading in two or more-quadrants, IRMA in one or more-quadrant or microaneurysm and dot-hemorrhages in all 4-quadrants. Proliferative diabetic retinopathy(PDR)can be divided into Non-High-riskPDR and High-RiskPDR in order to identify those eyes at greater risk of severe visual loss, and therefore most likely to benefit from panretinalPhotocoagulation(PRP), PRP may be successful by ablating areas of ischemic-retina, reducing the production of growth-factors responsible for neovascularization. C R O T IN PR T O N O *High-risk PDR is defined by the presence of three or more of the following characteristics {which requires PRP without-Delay}: Any-new-vessels, new vessels on-or-within one-disc-diameter of the optic-nerve head (NVD), Severe-new-vessels [as defined by one-third-disc-area neovascularization at the optic-nerve or one-half disc-area neovascularization elsewhere (NVE)], and pre-retinal or vitreous hemorrhage. D - O PY ,V IE W O N LY - 119 Clinically-significant macular-edema (CSME) is defined by the presence of retinal-thickening within 500microns of the foveal-center, hard-exudates within 500microns of the foveal-center associated with retinal-thickening, or retinal-thickening of one-disc-area-or-grater located partially-within one-disc-diameter of the foveal-center. *The presence of diabetic macular-edema, is a clinical determination made by the Stereoscopic-observation of retinal-thickening by contact lens-fundus examination or stereoPhotography. All eyes with PDR should undergo detailed examination of the Iris and angle for signs of growth of new-vessels (NVI, rubeosis) in order to avert the devastating development of neovascular-glaucoma in severely ischemic eyes or those with extensive retinal-detachment. N O T PR IN T O R C O PY ,V IE W O N LY D O *The importance of these distinction is that 52% of severe NPDR, versus 27% and 5% of moderate and mild NPDR respectively, progress to proliferative diabetic retinopathy (PDR), within 1-year. 120 The Early Treatment Diabetic Retinopathy Study ( ETDRS) evaluated the benefit of early panretinal-photocoagulation (PRP) in patients with mild to severe-NPDR. While early-PRP compared with-deferral of treatment; it was associated with a small-reduction in the rates of severe visual-loss to the 5/200 level or-worse over 5-years, (the incidence of such-loss was-decreased in-both the treatment and deferral-groups 2.6% and 3.7% respectively). The Diabetic Retinopathy Study (DRS) evaluated the benefits of panretinalphotocoagulation in eyes-with PDR; treated-eyes with high-risk-PDR were half-as-likely to-sustain severe visual-loss, to the 5/200 level or-worse at 4-years. PhotoCoagulation; reduces only 2-years rate of sever vision-loss (NEI). IN PR N O T The ETDRS evaluated-the-benefit of focal-or-grid laser-photocoagulation for the treatment of macular-edema. At 3-years treated-eyes with CSME were half-as-likely to-sustain moderate-visual-loss (doubling of the visual-angle) as-untreated-eyes (12% versus 24%). In eyes-with CSME and foveal-thickening, treatment-tripled the chance of moderate-visual-gain compared with untreated-eyes (17% versus 5%). O D T O R C O PY ,V IE W O N LY 121 Panretinal-Photocoagulation was found to worsen diabetic Macular-edema; more over, focal-laser treatment benefit-is-delayed until after the placement of panretinal-photocoagulation, as such, efforts should-be-made to treat diabetic macular-edema before the institution of panretinal-photocoagulation, if at all possible. Fluorescein-Angiography; is useful in identifying-sites of focal-leakage from microaneurysms, as well as diffuse-areas of leakage and cystoids-macular-edema. Areas of diffuse-leakage may benefit from treatment with a grid-pattern of laser in these areas. Extensive-diffuse-edema and cystoids-macula-edema are less-likely to-respond to-treatment. Despite-treatment with panretinal-photocoagulation, a small-portion of eyes still-progress to non-clearing vitreous-hemorrhage or traction-retinal-detach. Vitreous-surgery may be indicated when these complications-occur. O PY ,V IE W O T O O N The Diabetes Control and Complication Trail (DCCT) showed that intensive-therapy with tight-control of blood-sugars, as compared with conventional-therapy in patients with Type-I, IDDM delayed the onset and slowed-the-progression of diabetic retinopathy, nephropathy and neuropathy. D T PR IN R C O N LY 122 The Diabetic Retinopathy Vitrectomy Study (DRVS) examined the timing-and-benefit of vitrectomy in eyes with advanced-proliferative diabetic-retinopathy. *At 2-years early-vitrectomy for vitreous-hemorrhage compared with deferral, was associated with a three-fold-increased likelihood of achieving 20/40 or better visual-acuity(36% versus 12%). This benefit was only-present in Type-I diabetics; and no-difference in the ability to prevent severe visual-loss was observed for Type-II diabetics (28% versus 26%). *Four-years results of early-vitrectomy for eyes with severe-PDR characterized by extensive-neovascularization with fibrovascular-proliferation, showed an improved likelihood of achieving 20/40 or better visual-acuity compared with the deferral-group (44% versus 28%), but-again no-benefit in the prevention of severe visual-loss was observed.

A thin, central light-reflection in the center of the blood-column appears as a yellow-refractile-line about one-fifth the width of the column. As the wall of the arterioles become infiltrated with lipids and cholesterol, the vessels become sclerotic; as this process continues, the vessel-wall gradually-loses its transparency and becomes-visible, the blood column-appears wider than normal,and the thin-light-reflection becomes-broader. The grayish-yellow fat-products in the vessel-wall blend-with the red of the blood-column to produce a typical “cooper-wire” appearance; this indicates moderate-arterioSclerosis. As sclerosis-proceeds, the blood-column vessel-wall light-reflection resembles“silver-wire”,which indicates severe-arterioSclerosis; at times, which occlusion of an arteriolar-branch may occur. *Red-free light (a white-light with a green-filter) allows-detail of hemorrhages, focal-irregularity of blood-vessels, and nerve-fibers to be seen more clearly.

Ophthalmoscopy shows generalized and focal arterial-narrowing through-autoregulation, in-response to elevated perfusion-pressure. Narrowing is best-appreciated in-relative arterial-to-vein diameters,the so-called A/V-ratio. A normal-value is approximately 2/3. Over-time, arterial-walls lose their luster, assuming first a copper-color, and finally a silver-wire appearance. Depression of underlying-veins at crossing-sites by thickening arterial-walls typically occurs, referred to as A/V-nicking. Acute, severe (malignant) hypertension; produces visual-symptoms. Affected patients may complain of transient-obscuration of diminished central-visions. Systemic complaints may include headache, nausea and vomiting, alterations in mental-status, and convulsions. The retinal-venules may become dilated and tortuous in acutely or severely-elevated blood-pressure.

The blind-spot usually enlarges and may move-across their field of vision. This entire migraine phenomenon may end in only a few minutes, but usually lasts as long as about 20-30 minutes. Generally, ocular-migraines are considered harmless. Usually they are painless, cause no permanent visual or brain damage and do not require treatment. The vision symptoms accompanying painless ocular migraines are not related directly to the eyes. Instead, these visual symptoms occur as a result of the migraine “activity” in the visual cortex of the brain in the back of the skull.

Loss of Vision, from Occlusion of blood-Vessel in the Brain Neurologically significant field defects are most often central scotomas (due to optic nerve lesions), bitemporal field defects (due to chiasmal disease), or homonymous visual field defects (due to retrochiasmal damage to the optic tracts, the radiations, or the occipital cortex). In almost all locations, the effects produced are most profound within the central 30' of the visual field.

The level of a D O N O T PR IN T O R C O PY ,V IE W O N LY lesion can be determined by the specific deficit in the visual field. In the diagram of the cortex the numbers along the visual pathway indicate the sites of lesions. The deficits that result from lesions at each site are shown in the visual field maps on the right as black areas. Deficits in the visual field of the left eye represent what an individual would not see with the right eye closed rather than deficits of the left visual hemifield. 1. A lesion of the right optic nerve causes a total loss of vision in the right eye. 2. A lesion of the optic chiasm causes a loss of vision in the temporal halfes of both visual fields (bitemporal hemianopsia). Because the chiasm carries crossing fibers from both eyes, this is the only lesion in the visual system that causes a nonhomonymous deficit in vision, (ie. a deficit in two different parts of the visual field resulting from a single lesion). 3. A lesion of the optic tract causes a complete loss of vision in the opposite half of the visual field (contralateral hemianopsia). In this case, because the lesion is on the right side, vision loss occurs on the left side. 4. After leaving the lateral geniculate nucleus the fibers representing both retinas mix in the optic radiation. A lesion of the optic radiation fibers that curve into the temporal lobe (Meyer's loop) causes a loss of vision in the upper quadrant of the opposite half of the visual field of both eyes (upper contralateral quadrantic anopsia). 5, 6. Partial lesions of the visual cortex lead to partial field deficits on the opposite side. A lesion in the upper bank of the calcarine sulcus (5) causes a partial deficit in the inferior quadrant of the visual field on the opposite side. A lesion in the lower bank of the calcarine sulcus (6) causes a partial deficit in the superior quadrant of the visual field on the opposite side. A more extensive lesion of the visual cortex, including parts of both banks of the calcarine cortex, would cause a more extensive loss of vision in the contralateral hemifield. The central area of the visual field is unaffected by cortical lesions (5 and 6), probably because the representation of the foveal region of the retina is so extensive that a single lesion is unlikely to destroy the entire representation. The representation of the periphery of the visual field is smaller and hence more easily destroyed by a single lesion. 154 Isolated lesions anterior to the chiasm within the optic nerve produce visual field defects in one eye only. Optic nerve dysfunction typically produces a central scotoma, with accompanying reduction in visual acuity. Common causes of unilateral optic neuropathy include optic neuritis, optic nerve glioma, and meningioma. Lesions in the optic chiasm produce visual field defects that affect both eyes, but in a dissimilar fashion. The most common example is a bitemporal hemianopia caused by pituitary adenoma. Another common visual field defect due to disease near the chiasm is loss of central field in one eye and a temporal visual field defect in the other eye. Lesions affecting the visual pathways behind the chiasm produce homonymous hemianopia or homonymous defects that are less than a complete hemianopia. Because the fibers serving the corresponding portions of the two retinas lie increasingly closer together as the fibers pass back toward the occipital cortex, there is greater correspondence of the field defects in the two eyes as the lesions occur more posteriorly. Central visual acuity is not affected in homonymous hemianopia unless both hemispheres are involved. Stroke is the most common cause of a homonymous hemianopia. Middle cerebral artery occlusion tends to cause a complete hemianopia with other neurologic signs, whereas posterior cerebral artery occlusion causes isolated, congruous (identical) hemianopic scotomas.

D O N O T PR IN T O R C O PY ,V IE W O N LY 200 O PY ,V IE W Most of the time, all eyewear must sit on a patient with a certain amount of angle toward the face from the lower rim. This lower rim tilt toward the cheeks is called pantoscopic tilt, and it is needed in order for patients to rotate the eyes from distance to reading without having difficulty, looking under the glasses and in order to maintain vertex distance, also to decrease surface reflections. Pantoscopic tilt refers to the frame alignment in the up and down position of the frame. A properly adjusted frame will normally have 7-12 degrees of tilt towards the cheek. This provides the multifocal wearer the maximum benefit from the reading portion of the lens. O N O D T PR IN T O R C O N Standard Adjustment: The temples on the frame should be open and “equally angled to the front of the frame”. Before presenting a frame to a patient, ensure that the “temple tips” and “both corners of the front” lie in the “same plane”. Pantoscopic-tilt, vertex-distance and face-form are critical adjustments, to ensure patient comfort and good vision. We rotate the lens horizontally, or on the 180 meridian, for pantoscopic tilt. And we rotate the lens vertically, on the 90 meridian, for face form. LY 201 O PY ,V IE W C R Face form is the adjustment that matches the frame front to the wearer‟s facial shape. A correct face form adjustment matches the curve of the frame to the brow line. To add face form on a plastic frame, use the frame warmer until the frame is pliable and use gentle hand pressure to obtain the correct curvature. *To add face form on a metal frame, “bend the frame at the bridge” using gentle hand pressure. A “positive” face-form-tilt brings the left edge of the lens toward the observer and takes the right edge of the lens away from the observer. O N D O T PR IN T O O N LY *To obtain proper pantoscopic tilt, use angling pliers to “bend the temples down from the frame front at the end-piece”. A “positive” pantoscopic tilt displaces the top edge the lens “forward”, away from the patient‟s eyebrow in the usual configuration, and the bottom of the lens “backward” toward the cheekbone. -Retroscopic tilt is the opposite of pantoscopic tilt. The frame is tilted away from the cheek. Retroscopic tilt is sometimes necessary to fit frames on people with full cheeks, but it is not a desirable adjustment. 202 Vertex distance is the distance from the front of the cornea to the back of the lens. The frame front should be positioned as close as possible to the eye without the lenses touching the brow, lashes or cheeks. This provides the widest viewing areas in all parts of the lens. Proper vertex distance also helps eliminate back surface reflections on the lenses. *To obtain the correct vertex distance, adjust the “nose pads” on a metal frame with nose pad pliers to bring the “frame front” closer to or farther away from the face. When fitting a plastic frame, it is necessary to start with the proper bridge fit. *The three important “Nose-Pad” angles are: the frontal angle, the splay angle and the vertical angle. View the frontal angle from the “front of the frame”. Standard alignment of the frontal angle requires that the pads be closer together at the top than at the bottoms.

Standard alignment of the vertical angle requires that the bottom edges of the pads be closer to the eye-wires than the top edges of the pads. After the “frame-front” is adjusted, you are ready to adjust the temples. Temple wrap refers to the portion of the temple that extends “from the frame front to the top of the ear”. As with all adjustments, the closer the frame conforms to the face and head structure, the better the overall fit. In most cases, a very slight curve from front to back will help the temple to achieve a comfortable fit. The next consideration in adjusting the temple is the temple bend. This is the portion of the temple “from the top of the ear to the back of the ear”. A good temple bend will follow the contour of the ear. A good over-the-ear fit will allow gravity to work in your favor. The temple will lie close to the contours of the ear without pressing against it.

Special Note: No sleeping, no swimming, no showering and no bathing with your contact lenses on. Contact Lens Policy D O N O T PR IN T O R C Prescription release and expiration date: Your contact prescription is valid up to 1 year from the date of the EXAM. The expiration date is determined by the State law and our doctor and will be based on the health of your eyes, as well as your compliance with necessary follow-up care and lens use. After this time you cannot replace/purchase your contact lenses until you have a new exam or an updated prescription from another doctor. There is no valid prescription for contact lenses until you have completed the entire fitting process. Follow-up visits: After you get your contacts from us (even if you have worn them before), you must come back to our doctor to receive the follow-up exam(s). The importance of this is to make sure your contacts are fitting and interacting with your eyes properly. Remember that a contact lens is a medical devise and problems can occur that may not be felt. Our follow-up exams are designed as prevention of complications and to ensure good fit, comfort, and good vision. The cost of all regularly scheduled follow-up exams is included in your fitting. Failure to comply with these scheduled appointments such as not showing up, failing to call to reschedule, or a time lapse greater than the prescribed replacement of the trial contact lenses between follow-up will result in additional office visit fees or invalidation of the prescription. Disposable or frequent replacements: These lenses come in a specific Daily, Bi-weekly or Monthly replacement plans depending on the brand and the manufacturer’s recommendation. The brand is specific to the contact prescription, as is with any contact lens. You may not change brands without having been fit for that specific brand of contact lens. Spectacles: You must have a pair of spectacles with a usable prescription for times that you are not wearing the contact lenses. This can be an out of date prescription as long as it corrects your vision to 20/40 or better in each eye. By signing below; I agree to the conditions of the above stated office policy. I acknowledge that my failure to comply with this policy and/or proper recommended use and follow-up care of my CL, will result in my prescription being invalid. I have read all the enclosed material and have been instructed and educated on insertion, removal, and care of my contact lenses and I understand it completely. I acknowledge that I have chosen to assume the risk of injury or infection that may result from wearing my contact lenses, by failing to properly care for my lenses or failing to follow my doctor’s instructions regarding my contact lens wearing-time and replacement-schedule. Patient Signature: _______________________________ My next follow-up visit is: ________________ INFORMED REFUSAL — DILATION A dilated fundus exam is the use of eye drops to temporarily enlarge the pupil to allow for better viewing of the inside of the eye. Without dilation only 45% of the retina can be seen. Dilating the pupils may cause blurred vision, especially up close, and an increased sensitivity to light which may last up to 4 hours. Driving is usually not impaired but may require extra attention. A dilated exam is recommended on the initial examination. Every two years for those over 40, or whenever the doctor cannot properly evaluate your eyes without dilation. It is especially important for patients with a history of diabetes, high blood pressure, flashes of light or floaters, high spectacle prescriptions, glaucoma or a family history of eye disease. ____/____/____ (DATE) PY ,V IE W O N LY I, __________________________________ have been informed on this date by my optometrist of the need for a dilated examination of my eyes. It has been explained to me and I understand that a condition with the potential for partial or total loss of vision may exist and without dilation it may go undetected.

I have been informed and understand that if I have glaucoma and a pressure test is not performed, the disease may be undetected with the potential for a partial or total loss of vision. I have also been informed of the various means by which my eye pressure may be tested. Being advised of the above, I hereby decline an eye pressure test. _____________________________________ (PATIENT SIGNATURE) D O INFORMED REFUSAL — VISUAL FIELD TESTING / SCREENING Visual field testing is an important tool that measures, detects and monitors retinal function. This test can help in the early detection of many disorders including, but not limited to, glaucoma, retinal detachment and brain tumors. During this test you will be instructed to press a buzzer when you become aware of a small light within your peripheral field. Once the results are printed out by the computer your doctor can easily detect blind spots or other abnormalities in your visual field. Your optometrist strongly recommends this test, particularly for those patients who have any of the following: headaches, flashes of light or floaters, reduced vision without apparent reason, heart or circulatory problems, or those who take certain medications including plaquenil, and especially for glaucoma suspect patients. Date: I, ___________________________________ have been informed on this date by my optometrist of the need for a visual field test, have read the above and understand the importance of the findings and the information regarding the visual field testing.
