Gonioscopy was performed on 110 patients with primary open-angle glaucoma over the age of 40 and an equal number of normal subjects matched by race and age. The frequency distribution of various angle features differed in two groups. In the glaucoma group there were more iris processes at all levels of insertion, a higher insertion of the iris root, and more trabecular pigmentation. We believe that a congenital angle anomaly is an important factor in the pathogenesis of the elevated intraocular pressure.
