What does Evaporative Dry Eye Disease (EDED) stand for?

Explanation:
The name itself encodes the mechanism. EDED expands to Evaporative Dry Eye Disease, meaning dry eye caused by increased tear evaporation. This is usually due to a deficient lipid layer from Meibomian gland dysfunction, which destabilizes the tear film and leads to rapid tear evaporation and ocular surface irritation. It’s distinct from aqueous-deficient dry eye, where tear production is reduced rather than evaporation increased. The other terms would imply involvement of different tissues or non-evaporative mechanisms, so they don’t fit the concept of an evaporation-driven tear film disorder.
