The Real Cause and Extent of Evaporative Dry Eye
Dry Eye is a long-term chronic disease that takes years to develop. There are two main forms, evaporative and aqueous deficient. It’s only recently that researchers have been able to pinpoint the differences and the causes.
At least 65% of dry eye patients have Evaporative Dry Eye. This occurs when the water (or aqueous) in tears evaporates at a faster rate than normal, due to an insufficient lipid (oil) layer on the surface of the tear film. It’s a result of blockage in the oil-producing meibomian glands located within the eyelids (referred to as Meibomian Gland Dysfunction)1.
Very few patients suffer exclusively from Aqueous Deficient Dry Eye, which occurs when aqueous generation from the lacrimal gland is insufficient to keep the eyes moist.
If you’ve been unable to receive long-lasting relief from the remedies you’ve tried, it may be because they haven’t been targeting the primary cause of your condition.
