This study evaluated the effect of argon laser iridoplasty (ALI) on 11 eyes with primary chronic angle closure glaucoma (CACG). All eyes had an intraocular pressure greater than 20 mmHg despite maximum medical therapy and were followed up for six months after ALI. Iridoplasty successfully opened at least half of the angle in all eyes, maximally reducing the intraocular pressure (IOP) in all eyes in the first week (paired t test p < 0.002). At three months, the IOP in 7 eyes were medically controlled while 4 eyes required trabeculectomy. The results at six months showed no further changes. Iridoplasty may be useful for lowering IOP in CACG and avoiding the need for surgery for up to six months in 64% of the eyes studied.
本研究评估了氩激光虹膜成形术（ALI）对11只原发性慢性闭角型青光眼（CACG）患眼的疗效。尽管采用了最大剂量的药物治疗，所有患眼的眼压均高于20 mmHg，并在氩激光虹膜成形术后随访6个月。虹膜成形术成功使所有患眼的房角至少开放一半，在第一周时所有患眼的眼压均显著降低（配对t检验p<0.002）。3个月时，7只眼的眼压通过药物得到控制，而4只眼需要进行小梁切除术。6个月时的结果显示无进一步变化。虹膜成形术可能有助于降低慢性闭角型青光眼的眼压，并且在所研究的64%的患眼中可避免长达6个月的手术需求。
