Abstract
Dry eye disease, as an ocular surface disorder, affects millions of people globally and has consequently become one of the most prevalent conditions encountered in ophthalmic clinics. The pathogenesis of dry eye involves several key factors, including tear film instability, hyperosmolarity, chronic ocular surface inflammation, and neurosensory abnormalities. The ocular surface expresses a diverse array of ion channels, which play essential physiological roles in maintaining tear film stability, regulating osmotic pressure, balancing ion transport, and modulating inflammatory responses. This review systematically elucidates the relationship between ion channels and dry eye disease through three key aspects: the distribution and physiological functions of ion channels in ocular surface tissues, the therapeutic efficacy and mechanistic basis of ion channel targeted modulators in dry eye treatment, and a comprehensive classification of molecular mechanisms underlying ion channel targeted therapies for dry eye. Research on these targeted mechanisms establishes a theoretical foundation for clinical dry eye management and provides innovative strategies for developing novel ion channel based therapeutics.
