bstractPurpose To evaluate the changes in accommodation amplitude in cases with pseudoexfoliation. Materials and methods Twenty-nine eyes having pseudoexfoliation and 37 normal eyes aged between 40-60 years were included in the study. After ophthalmic examination, accommodation amplitude was measured using Powerrefractor II. Besides, axial length, anterior chamber depth, and lens thickness was measured by A-scan ultrasonography. The results obtained were evaluated by independent samples' t-test. Results There was no difference in mean age between cases with pseudoexfoliation and normal cases (P ¼ 0.131). Mean accommodation amplitude was significantly lower in cases with pseudoexfoliation (P ¼ 0.002). Axial length, anterior chamber depth, and lens thickness measurements did not show significant change between groups (P ¼ 0.55, P ¼ 0.66, P ¼ 0.36, respectively). Conclusion In the presence of pseudoexfoliation, ciliary apparatus can be affected and accommodation amplitude can be decreased in earlier ages.
