ABSTRACT
In order to evaluate the morphologic types of appositional angle-closure glaucoma, biometric measurements were made in angle-closure glaucoma patients using Ultrasound biomicroscopy (UBM). Twenty-six patients with primary angle-closure glaucoma and 21 cataract patients with as a control group were examined. The angle-closure glaucomatous eyes were classified as type B in which the angle closure started at the bottom of the angle and type S in which the angle closure occurred in the vicinity of Schwalbe's line. The trabecular-ciliary process distance (TCPD, type B; 873.20+/-86.77 microm, type S; 832.52+/-82.96 microm, control; 1233.50+/-73.01 microm, p = 0.000) and the angle opening distance (AOD500, type B; 89.75+/-63.27 microm, type S; 88.85+/-72.95 microm, control; 304.40+/-104.30 microm, p = 0.000) were significantly shorter in patients with angle closure vice control group. No significant difference were noted in the three groups of patients in regards to iris thickness or ciliary process-iris angle. In this study, we have demonstrated that there are two types of appositional angle-closure and have shown the forward rotation of the ciliary process without changes of the ciliary process-iris angle in cases of angle-closure glaucoma.
