Tear film insufficiency

Tear film insufficiency refers to an ocular surface disorder characterized by a quantitative deficiency or qualitative instability in the precorneal tear film, encompassing conditions such as aqueous-deficient dry eye disease and evaporative dry eye states Pathophysiologically, lacrimal gland hyposecretion, lipid layer abnormalities, or altered mucin production lead to tear hyperosmolarity, rapid tear film breakup, and ocular surface inflammation
