Changes in anterior segment morphology after laser peripheral iridotomy: An anterior segment optical coherence tomography study

Abstract

Purpose: Novel anterior segment optical coherence tomography (ASOCT) parameters associated with angle closure include anterior chamber area (ACA), anterior chamber volume (ACV), anterior chamber width (ACW), lens vault (LV), iris thickness (IT), iris area (I-area), and iris curvature (I-curv). We aimed to investigate changes in these parameters after laser peripheral iridotomy (LPI) in a cohort of primary angle-closure suspects (PACS). Design: Prospective observational study. Participants and Controls: A total of 176 PACS aged <50 years who underwent LPI in 1 eye. Methods: We analyzed ASOCT images (Visante, Carl Zeiss Meditec, Dublin, CA) from all subjects using customized software before an..
