摘　　要：应用Storz公司生产的笑气冷凝器对28例(28只眼)穿透角膜移植术后药物及常规滤过手术不能控制眼压的青光眼施行睫状体冷冻术,并进行一年以上的随访观察。结果表明:用睫状体冷冻术治疗穿透角膜移植术后难治性青光眼其控制眼压的有效率达89％,移植片透明率达85％,视功能的有效保存率达82％。准确把握手术时机,严格控制冷冻温度、时间与范围,术后联合抗排斥措施是确保手术成功的关键。切忌一次冷凝过度造成眼球萎缩或一次冷凝不足便放弃治疗。Twenty-eight patients (28 eyes) with secondary glaucoma following penetrating keratoplasty and failed to respond to anti-glaucoma drugs and routine filtering procedures were performed with cyclocryotherapy by nitrogen monoxide. All patines were followed up for more than one year. The results showed intraocular pressure was well controlled in 89% of the eyes,graft remained clear in 85%, and visual functions are preserved in 82% of the patients. Our study suggests that precisely controlled temperature, time, and extent of cryotherapy,and post-operative anti-rejection agents be the key factor to success. Over-treatment,which may lead to atrophy of the eye,must be avoided. It should not be given up flowing under-treatment in the intial procedure.
