Forty-nine eyes were treated with iridectomy for primary acute angle-closure glaucoma. Forty asymptomatic, normotensive fellow eyes were similarly treated. The duration of follow-up after surgery was 52.3 +/- 3.6 months. Thirty-seven (76%) of the eyes with acute attacks were cured by iridectomy alone and required no medical therapy. Twelve eyes (24%) developed increased intraocular pressure following iridectomy, but only one eye (2%) required filtering surgery. Eighty-eight percent of the asymptomatic, normotensive fellow eyes required no subsequent therapy, and none developed visual field defects. Visual acuity was unchanged in 22 of 49 (45%) of the acutely involved eyes and decreased more than six lines in 11 (22%) eyes. In the 40 fellow eyes, visual acuity was unchanged in 63% and decreased more than six lines in only one (2%) eye.
49只眼睛因原发性急性闭角型青光眼接受了虹膜切除术治疗。40只无症状、血压正常的对侧眼也接受了同样的治疗。术后随访时间为52.3±3.6个月。37只（76%）急性发作的眼睛仅通过虹膜切除术就治愈了，无需药物治疗。12只眼睛（24%）在虹膜切除术后眼压升高，但只有1只眼睛（2%）需要进行滤过手术。88%的无症状、血压正常的对侧眼无需后续治疗，且无一例出现视野缺损。49只急性发病眼中有22只（45%）视力无变化，11只眼睛（22%）视力下降超过6行。在40只对侧眼中，63%视力无变化，只有1只眼睛（2%）视力下降超过6行。
