Although this condition affects the health and well-being of millions of people, there is no global consensus on the definition, classification, diagnosis, or therapy for MGD. To achieve such a consensus, the Tear Film and Ocular Surface Society (TFOS; http://www.tearfilm.org), a nonprofit organization, launched the International Workshop on Meibomian Gland Dysfunction (www.tearfilm.org/mgdworkshop/index.html). The objectives of the workshop were to: in Invest. Ophthalmol. Vis.

The report of the Workshop on MGD, which required more than 2 years to complete, was finalized in 2010. This effort involved more than 50 leading clinical and basic research experts from around the world. These participants, who were assigned to subcommittees, reviewed published data and examined the levels of supporting evidence. Subcommittee reports were circulated among all workshop participants, presented in open forum, and discussed in an interactive manner.

At this stage, affected individuals may be symptomatic, but alternatively, they may be asymptomatic and the condition regarded as subclinical.

At this point, an MGD-related posterior blepharitis is said to be present. The term MGD is regarded as appropriate for describing the functional abnormalities of the meibomian glands.
