OBJECTIVE: To evaluate the association between baseline measurements of iris thickness at 3 positions and change in anterior segment biometric parameters after prophylactic laser peripheral iridotomy (LPI). DESIGN: Prospective clinical cohort study. PARTICIPANTS: Fifty-two eyes of 52 nonglaucomatous subjects with anatomically narrow angles. METHODS: Anterior segment optical coherence tomography (ASOCT) images captured before and after LPI were analyzed using customized software, the Zhongshan Angle Assessment Program (ZAAP) (Zhongshan Ophthalmic Centre, Guangzhou, China). Differences in preoperative and postoperative measurements for anterior segment biometric parameters were compared by pai..View full abstract
