Comparison of Anterior Segment Parameters Obtained by Dual-Scheimpflug Analyzer Before and After Cycloplegia in Children

Abstract

Purpose: 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. © SLACK Incorporated.
