Types of Dry Eyes

There are two main types of dry eyes and this includes:

ADDE: Aqueous Deficient Dry Eyes – which is simply defined as a reduction in the production of tears.

EDE: Evaporative Dry Eyes – which is the loss of tears from the surface of the eye when there is normal production of tears.

Meibomian Gland Dysfunction MGD is the result when the Meibomian glands cease to function optimally. MGD is associated with Evaporative Dry Eye. These blocked glands can no longer secrete the oils necessary to maintaining a healthy tear film. MGD is often thought to be the leading cause of dry eye disease. If MGD is left untreated for an extended period of time, permanent damage to the eyes may occur.

Although, dry eyes are broadly classified into these two categories, they are not mutually exclusive and you can have a combination of the two.
