Anterior Segment Optical Coherence Tomography for Imaging the Anterior Chamber After Laser Peripheral Iridotomy - 21/08/11
Inquiries to David Huang, Doheny Eye Institute, 1450 San Pablo Street, DEI5702, Los Angeles, CA 90033Résumé |
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.
