Visual field status in the management of chronic angle-closure glaucoma

A retrospective analysis of the case histories of 40 patients with chronic angle-closure glaucoma yielded 31 eyes without visual field loss and 26 eyes with field loss. Peripheral iridectomy was highly successful in cases without field loss. Trabeculectomy was significantly more successful (93%) than iridectomy (64%) in treating cases with field loss. It is suggested that the choice of surgical procedure in this syndrome be dictated in part by the character of the visual field.
