| Popis: | Primary angle closure glaucoma is common in certain regions of the world and is an important cause of blindness worldwide. Currently accepted treatment for patients with anatomically narrow angles is laser peripheral iridotomy (LPI). Gonioscopy is currently the standard clinical tool for detecting occludable angles. However, this subjective technique is limited by interobserver bias and is difficult to perform in a reproducible fashion. Ultrasound biomicroscopy (UBM) is a more objective and reproducible method of angle assessment,1, 2 but the contact or immersion requirement is inconvenient and may cause artifactual widening of the angle. Optical coherence tomography (OCT)3 is a new imaging modality that allows high-resolution, cross-sectional imaging of the eye.4-5 OCT requires no contact or immersion and has higher spatial resolution than ultrasound. In this study, we used OCT to quantify changes in anterior segment morphology after LPI. |
