Dry eye

Dry eye, also known as dry eye disease or keratoconjunctivitis sicca, is a multifactorial ocular condition characterized by a loss of tear film homeostasis It primarily affects the ocular surface, including the cornea and conjunctiva, and occurs across diverse demographics, with an increased prevalence in older adults and females The condition arises from tear hyperosmolarity and tear film instability driven by either inadequate aqueous tear secretion or excessive tear evaporation, frequently se...

It primarily affects the ocular surface, including the cornea and conjunctiva, and occurs across diverse demographics, with an increased prevalence in older adults and females

The condition arises from tear hyperosmolarity and tear film instability driven by either inadequate aqueous tear secretion or excessive tear evaporation, frequently secondary to meibomian gland dysfunction This cycle triggers localized ocular surface inflammation, sensory nerve abnormalities, and tissue damage, manifesting clinically as eye discomfort, burning or gritty sensations, visual disturbances, and photophobia
