title: Comparison of Anterior Segment Parameters Obtained by Dual-Scheimpflug Analyzer Before and After Cycloplegia in Children.
abstract: OBJECTIVE
  To assess the changes of anterior segment parameters with cycloplegia.
  
  
  METHODS
  A cross-sectional study of healthy pediatric patients was performed. Anterior segment parameters were obtained by the Galilei Dual-Scheimpflug analyzer (Ziemer Group, Port, Switzerland) before and 40 minutes after the instillation of cyclopentolate. The effect of gender was evaluated.
  
  
  RESULTS
  There were 43 boys and 50 girls with a mean age of 7.76 ± 2.7 years. There was a significant increase in anterior chamber depth, anterior chamber volume, and pupil diameter after the cycloplegia (P < .05). The anterior chamber angle increased after cycloplegia in the nasal, temporal, and inferior quadrants (P < .05), but not in the superior quadrant (P > .05). The mean values of anterior segment parameters were similar in both genders.
  
  
  CONCLUSIONS
  The values of anterior chamber depth, anterior chamber volume, anterior chamber angle, and pupil diameter measured with the Galilei Dual-Scheimpflug analyzer increased significantly after cycloplegia. Gender did not have an effect on anterior segment parameters. [J Pediatr Ophthalmol Strabismus. 2016;53(4):234-237.].
