Abstract

Objective: To evaluate changes in anterior segment anatomy after laser iridotomy for pigment dispersion syndrome. Methods: Ultrasound biomicroscopy was performed on 7 eyes of 7 untreated patients with reverse pupillary block and pigment dispersion syndrome. A radially oriented image with the probe perpendicular to the eye in the superior meridian was obtained before and at least 1 week after laser iridotomy in each eye. We assessed changes in angle recess area and iris-lens contact distance. Results: Mean ± SD patient age was 31.3 ± 5.7 years and mean ±SD refractive error was -5.0 ± 3.9 diopters. Angle recess area (mean ±SD, 0.78 ± 0.28 vs 0.35 ±0.11 mm2; P=.001, paired t test) and iris-lens contact distance (2.05 ± 0.28 vs 0.79 ± 0.13 mm; P<001) decreased following iridotomy. Central anterior chamber depth did not change. Conclusion: Flattening of the iris following laser iridotomy for pigment dispersion syndrome Causes a decrease in iris-lens contact and angle width while lens position remains constant.
