A retrospective study of 57 eyes with chronic angle-closure showed that eyes with visual field loss are less likely to be improved by iridectomy than those without visual field loss in the presence of visual field loss, trabeculectomy achieved more satisfactory control of glaucoma than did iridectomy, and there was no noticeable difference in surgical complications between iridectomy and trabeculectomy in this small series. It is suggested that iridectomy is indicated for most cases of chronic angle closure without visual field loss, especially if the pressure is medically controllable. In the presence of visual field loss, iridectomy is usually a wise choice if medical control is easily achieved preoperatively. However, trabeculectomy might be the best choice in most patients with visual field loss and medically uncontrolled pressure, regardless of the gonioscopic findings.
一项对57只慢性闭角型青光眼患眼的回顾性研究表明，存在视野缺损时，有视野缺损的患眼通过虹膜切除术改善的可能性低于无视野缺损的患眼；小梁切除术在控制青光眼方面比虹膜切除术更令人满意；在这个小样本系列中，虹膜切除术和小梁切除术的手术并发症没有明显差异。建议对于大多数无视野缺损的慢性闭角型青光眼病例，尤其是眼压可通过药物控制的情况，虹膜切除术是适用的。存在视野缺损时，如果术前能轻松实现药物控制，虹膜切除术通常是明智的选择。然而，对于大多数有视野缺损且眼压无法通过药物控制的患者，无论房角镜检查结果如何，小梁切除术可能是最佳选择。
