How are pupillary parameters affected in pseudoexfoliation syndrome? A quantitative study

Purpose We evaluated the effects of pseudoexfoliation syndrome on dynamic, static pupillary parameters (scotopic, mesopic, photopic) and the pupil dilation speed, with automatic pupillometry. Material and methods The study group included 140 eyes with clinically visible pseudoexfoliation material (PXM) of 110 patients. The study group was compared with the control group formed by including 140 eyes of 110 patients. Scotopic measurements at 0.4 lx illumination, mesopic measurements at 4 lx illumination, and photopic measurements at 40 lx illumination were performed. Dynamic measurements were made at 500 lx illumination. The mean pupil dilation speed at 10th second was calculated. In addition, the eyes (80 patients) with clinically unilateral PXM were compared with the other eyes of the patients. Results The mean scotopic, mesopic, photopic and dynamic pupil diameters of eyes with clinical PXM were compared with the control group, all values were found to be significantly lower in eyes with PXM.
