An argon laser iridectomy was performed on 18 eyes of 14 patients with closed-angle glaucoma. The intraocular pressure (IOP) was controlled in all but one eye within normal limits. Variable amounts of pigment were found on gonioscopy in all cases. The mydriasis test was positive in one eye (5.5%) after homatropine and in 5 eyes (28%) after tropicamide drops. 80% of the positive results occurred in lightly pigmented irides. The dark-prone position test was positive in 7 eyes (38%), 71% of the positive results occurring in heavily pigmented irides. Tomography was also performed; the possibility of trabecular damage is discussed.
对14例闭角型青光眼患者的18只眼睛进行了氩激光虹膜切除术。除1只眼睛外，所有眼睛的眼压均控制在正常范围内。所有病例在房角镜检查中均发现了不同量的色素。用后马托品滴眼后，1只眼睛（5.5%）的散瞳试验呈阳性，用托吡卡胺滴眼后，5只眼睛（28%）的散瞳试验呈阳性。80%的阳性结果出现在色素较浅的虹膜中。暗俯卧位试验在7只眼睛（38%）呈阳性，71%的阳性结果出现在色素较深的虹膜中。还进行了断层扫描；讨论了小梁损伤的可能性。
