Ocular complications in adults with psoriasis: a cross-sectional study in a referral center in Brazil

Purpose There is limited literature on the ocular manifestations in patients with psoriasis. Therefore, this study aimed to identify the prevalence of and factors associated with ocular manifestations in adults with psoriasis. Methods This cross-sectional study included Brazilian adults with psoriasis. The dermatological evaluation included diagnosis, clinical form, Psoriasis Area and Severity Index (PASI) measurement, and location of the lesions.

A significant correlation was observed between MGD and PASI ( p = 0.05), and between MGD and certain treatment modalities. DED was significantly associated with PASI ( p
