Abstract;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 .MU.l) was significantly smaller than for the other groups(post LI group: 96.4.+-.21.4 .MU.l; OAG group: 144.2.+-.31.6,ul, 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. (author abst.)
