为探讨预防青光眼患者健眼青光眼急性发作的方法，应用ＮｄＹＡＧ激光虹膜切除术替代传统的开放式周边虹膜切除术。选择上方虹膜１１００或１００或下方虹膜５００～７００，于虹膜中１／３与外１／３交界处之隐窝区作切口，对单眼典型青光眼急性发作者３１２例之健眼行上述手术，经８～８０个月（平均４３个月）随访观察，成功３０３例（成功率９７．１％）；失败９例（失败率２．９％），其中３例激光孔封闭、４例非适应证、２例原因不明。结果表明，该疗法经济快捷，安全无痛苦，远期疗效稳定可靠。提示ＮｄＹＡＧ激光虹膜切除术可成功地预防健眼闭角型青光眼的急性发作。
To explore the method of preventing acute glaucoma in glaucoma patients, NdYAG laser iridectomy should be used instead of the traditional open peripheral iridotomy. Select the top of the iris 1100 or 100 or below the irises 500 to 700, in the iris 1/3 and 1/3 at the junction of the junction of the recess area of the eyes of a typical glaucoma acute attack 312 cases of eye health the above operation, Eighty-eight months (mean 43 months) were followed up, 303 cases were successful (success rate was 97.1%), 9 cases failed (failure rate was 2.9%), 3 were laser hole closed and 4 were non-indications , 2 cases of unknown cause.
