PURPOSE: The anterior ocular segment topography in angle-closure glaucoma was studied using the non-contact three-dimensional anterior segment analyzer Pentacam. SUBJECTS AND METHODS: The central anterior chamber (AC) depth, mid-peripheral AC depth, peripheral AC depth, AC volume, central AC depth/ocular axial length ratio and angles of a narrow angle group (47 eyes of 29 patients), a post laser iridotomy (LI) group (43 eyes of 30 patients), and an open-angle glaucoma (OAG) group (37 eyes of 21 patients) were measured and compared. In addition, changes in the parameters before and after LI (13 eyes of 9 patients) were investigated. RESULTS: The AC volume for the narrow angle group (74.5 ± 21.1 μl) was significantly smaller than for the other groups (post LI group: 96.4 ± 21.4 μl; OAG group: 144.2 ± 31.6 μl, p < 0.001). The most significant association was detected between AC volume and the peripheral AC depth. Only two parameters, AC volume and peripheral AC depth, increased significantly after LI (p < 0.001). DISCUSSION: Measurement of the AC volume and the peripheral AC depth using Pentacam is useful for evaluating the anterior ocular segment topography in narrow angle eyes. LA: Japanese
