title: Evaluation of the change in accommodation amplitude in subjects with pseudoexfoliation.
abstract: OBJECTIVE
  To evaluate the changes in accommodation amplitude in cases with pseudoexfoliation.
  
  
  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=0.131). Mean accommodation amplitude was significantly lower in cases with pseudoexfoliation (P=0.002). Axial length, anterior chamber depth, and lens thickness measurements did not show significant change between groups (P=0.55, P=0.66, P=0.36, respectively).
  
  
  CONCLUSIONS
  In the presence of pseudoexfoliation, ciliary apparatus can be affected and accommodation amplitude can be decreased in earlier ages.
