[Anterior chamber dimensions in patients with angle-closure glaucoma measured by an anterior eye segment analysis system].

The corneal curvatures, iridocorneal angles, anterior chamber depths, and anterior chamber volumes in 26 (5 male and 21 female) patients with primary angle-closure glaucoma were measured using an anterior eye segment analysis system (EAS-1000, Nidek). The radius of corneal curvature was 7.65 +/- 0.25 mm (mean +/- standard deviation), significantly smaller than age-matched controls, and the iridocorneal angles ranged between 19 and 21 degrees. The anterior chamber depth and volume of angle-closure glaucoma eyes did not correlate with age; the depth averaged 1.90 +/- 0.41 mm, and the volume averaged 83.3 +/- 28.4 microliters.
