NCT04351100

Brief Summary

Dry eyes is multi-factorial disease which inflammation play etiological role. Diacerein is drug which has anti-inflammatory effect by antagonist Interleukin-1, decrease Interleukin-1 receptor, increase Interleukin-1 Receptor antagonist. This observational study enrolled participants who going to take diacerein for osteoarthritis, measure corneal staining score, Ocular surface disease index score, Tear Osmolarity, Tear break up time, Schirmer 1 test, Interleukin-1 Receptor antagonist, Interleukin-1 alpha, Interleukin-1 beta level in tear at the time of enrollment and after 2 months.
