PURPOSE: To evaluate changes in anterior segment morphology by anterior segment optical coherence tomography (OCT) and gonioscopy before and after laser peripheral iridotomy (LPI). DESIGN: Prospective comparative observational case series. METHODS: Ten eyes of 10 patients with narrow angles were enrolled in the study. Angles were assessed by gonioscopy and anterior segment OCT pre- and post-LPI. The angle opening distance at 500 μm, angle recess area at 500 μm and 750 μm, and trabecular-iris space area at 500 μm and 750 μm were compared pre- and post-LPI. RESULTS: The mean gonioscopy grade increased significantly from 0.56 to 2.6 (P < .001). All OCT parameters increased significantly post-LPI. CONCLUSIONS: Changes in the anterior chamber angle morphology post-LPI can be imaged and objectively quantified by anterior segment OCT.
