PURPOSE– To study the pupil size and effect of mydriatics in patients with pseudoexfoliation. METHODS– A group of 50 patients above the age of 40 years with pseudoexfoliation were selected over a period of 6months in a tertiary care hospital. RESULTS – It was observed that 50% of our patients belonged to the age group of 61–70 years. There were an equal number of male and female patients. 38% of the participants had small pupil prior to dilatation and 82% had small pupil after dilatation. There was no significant correlation between age, sex and small pupil in patients with pseudoexfoliation.– CONCLUSION– Thus, thorough and careful planning, surgery and postoperative care, the risk of complications in PXF patients can be minimized, thereby allowing them to achieve good visual results.
