氩激光和Nd:YAG激光联合虹膜切除治疗葡萄膜炎继发闭角型青光眼

Combing argon laser and Nd:YAG laser iridectomy to therapy angle-closure glaucoma following uveitis

目的探讨葡萄膜炎瞳孔闭锁继发闭角型青光眼的激光治疗。方法对9例(9只眼)葡萄膜炎继发闭角型青光眼行氩激光和Nd:YAG激光联合虹膜切除术。在选择虹膜切除的部位先用氩激光在虹膜表面行分层击射,使虹膜收缩、部分炭化,后用Nd:YAG激光作穿透击射,形成一个1～1.5mm的虹膜根切孔。结果术后随访4～16个月,9只眼激光虹膜切除孔均保持通畅,眼压控制良好,除1只眼术中虹膜少量出血,余无其他并发症。结论氩激光与Nd:YAG激光联合行虹膜切除术是治疗葡萄膜炎瞳孔闭锁继发闭角型青光眼的一种安全有效的方法。

Objective To discussb the laser therapy of angle-closure glaucoma following uveitis seclusion of the pupil. Methods The methods that argon laser and Nd ： YAG laser combing with iridectomy were used to treat 9 eyes of angle-closure glaucoma following uveitis. Argon laser was used to partial-layer shot in iris surface that choosed to be therapied by iridectomy. Then Nd：YAG laser was used to whole-layer shot after iris shrinkage and charring . So a hole diammter is 1 mm～ 1.5 mm was formed. Results The patients were observed 4 to 16 months after surgery . 9 iridectomy hole are through , and eye pressure are all right . Only one patients iris has little haemorrhage during surgery .. The others have no syndrome. Conclusion Argon laser and Nd：YAG laser combined with iridectomy is a safe and effetive Methods to therapy angle-closure glaucoma following uveitis seclusion of the pupil . The key are effectively control inflammation and forepart surgery .
