激光周边虹膜切除术治疗早期原发或继发性闭角型青光眼效果较好,较手术切除并发症少且方便。过去曾用氩激光造成的虹膜孔常不够大,且由于色素增殖易发生虹膜孔闭合。自钕钇铝石榴石(YAG)激光问世,一致认为YAG 激光虹膜切除较氩激光好,主要是不易发生虹膜孔的闭合。但是YAG激光击穿虹膜的机制是电离效应的微小爆炸作用,故易发生术中虹膜出血,给激光手术增加困难和并发症。为了减少虹膜出血,我们设计先用氩激光局部光凝,减少YAG 激光虹膜切除过程中的出血,收到满意效果,现报告如下。 Laser peripheral iridotomy for early primary or secondary angle-closure glaucoma better, less complications than surgical resection and convenience. In the past, the iris holes caused by argon laser were often not large enough, and the iris holes were easily closed due to the proliferation of the pigment. Since the advent of Nd: YAG lasers, it has been agreed that YAG laser iridectomy is better than Argon laser, and that the occlusion of iris holes is not easy to occur mainly. However, YAG laser puncture the iris mechanism is a small explosion of ionization effect, it is prone to intraoperative iris bleeding, laser surgery to increase difficulties and complications. In order to reduce iris bleeding, we designed the first local laser photocoagulation with argon laser to reduce bleeding during YAG laser iridectomy, and received satisfactory results, are as follows.
