This study aimed to examine the effect of Tiotropium, which is used in the treatment of COPD, on eye symptoms.The study was conducted prospectively. Patients were examined in three groups. Thirty-six patients were included in each group in the study. Anterior chamber parameters, intraocular pressure values, and photopic-mesopic pupil diameters were measured at the initial visit for Group 1 and Group 2 patients, and at the third month of treatment for Group 3 patients.
