　　［摘要］  目的  探讨氪激光周边虹膜成形术治疗原发性闭角型青光眼急性发作的安全性和有效性。方法  原发性闭角型青光眼第一次急性发作者，经检查确诊后立即给予1%匹罗卡品及0.5%噻吗心安点眼，1 h后眼压仍不能下降至40 mm Hg以下者24例24眼行氪激光周边虹膜成形术，观察治疗前及治疗后30 min、1、2、24 h的症状、视力、角膜水肿、眼压及前房角变化。结果  氪激光周边虹膜成形术30 min后，眼压从42～81 mm Hg降至25～72 mm Hg，平均下降10.7%；术后1 h眼压为15～47 mm Hg，平均下降58.2%；术后2 h眼压为12～28 mm Hg，平均下降71.4%；术后24 h眼压为9～18 mm Hg，均降至正常，平均下降82.7%。激光治疗后患者不适症状迅速缓解，视力快速提高，角膜水肿消退，前房角有不同程度的加宽。结论  氪激光周边虹膜成形术能机械性拉开房角，迅速降低原发性闭角型青光眼急性发作期的眼压，起效快，并发症少，是治疗青光眼急性发作的一种安全有效的方法。
