Ocular findings in patients with psoriasis

Background  Psoriasis is a chronic inflammatory disease affecting skin, nails, and joints. Although there are not many reports in the literature, ocular findings occur in approximately 10% of patients, in mostly those who have psoriatic arthritis. In this study, we aimed to evaluate eye involvement in psoriasis patients. Methods  This study was performed on a total of 100 psoriasis patients and a group of 100 healthy individuals. History was taken from all study and control subjects, and dermatological, systemic, and ophthalmological examinations were performed and Schirmer and BUT values were measured. Constant variables were compared using the t-test, and categorical variables were compared using chi-square test. Relationship between ocular findings and sex, age, duration of psoriasis, PASI score, presence of psoriatic plaques on the eyelid, nail involvement, and psoriatic arthritis was evaluated using logistic regression analysis. Statistical analyses were performed individually for both right and left eyes. Results  The number of ocular findings in both eyes in the patient group was found to be statistically higher than that in the control group. Schirmer and BUT values were statistically lower in the patient group than those in the control group. Conclusions  Although results of our study support the necessity of routine ophthalmological examination of psoriasis patients for early diagnosis and treatment, we believe that further studies are required on the etiopathogenesis of ocular involvement in psoriasis patients.
