Meibomian gland dysfunction

Meibomian gland dysfunction

 

(MGD) is one of the most prevalent ailments that ophthalmologists diagnose. In more than 2/3 of cases of patients suffering from the common symptoms of dry eyes, meibomian gland dysfunction is to blame.

 

The meibomian gland is responsible for secreting an oil film of lipids which cover the outer most surface of the eyes. The purpose of this lipid layer is to keep the layer of tears which rests beneath it from evaporating in dry environments.

 

When someone suffers from meibomian gland dysfunction, this oily shield of lipids is not produced sufficiently and the tear layer evaporates more quickly than it might otherwise do, forcing the lacrimal gland to work overtime in order to keep the eye moisturized. Unfortunately, the tear layer is rarely able to keep up with this level of production, and the eye inevitably dries out unless other preventative measures are utilized (e.g., eye drops are applied).
