Abstract

Purpose: To investigate whether subclinical ciliochoroidal effusion and resulting asymptomatic angle narrowing occurs in patients taking topiramate, by ultrasound biomicroscopy (UBM).Methods: Chinese patients aged 18-75 years for whom topiramate was indicated were recruited. Examinations including UBM were performed before and 4 weeks after commencement of topiramate.Results: In this pilot of 20 eyes of 20 patients, there were no statistically significant changes in the angle parameters noted on gonioscopy or UBM, including anterior chamber depth, angle-opening distance at 500 m, trabecular ciliary process distance, trabecular-iris angle, and scleral thickness.Conclusion: Short-term use of topiramate does not induce asymptomatic angle narrowing.
