目的探讨ＹＡＧ激光行虹膜后粘连切开的可行性。方法对我科１９９６年４月至１９９８年１２月收治的慢性虹膜后粘连病人２１例２５眼，控制炎症反应１月，治疗前３天结膜下注射庆大霉素２万单位、地塞米松２ｍｇ及阿托品０．３ｍｇ，采用国产ＹＡＧ激光，能量４．１～８．１ｍｊ，光斑直径２８ｕｍ，治疗前托品酰胚点眼加强散瞳，准确聚焦自下向上击射后粘连。结果２５眼中有１２眼治疗后瞳孔正圆，另１３眼瞳孔有缺损，其中后粘连＜３处者可完全解除后粘连，３～５处者亦有效。结论ＹＡＧ激光虹膜后粘连切开术对于虹膜后粘连治疗行之有效。
Objective To investigate the feasibility of posterior Iment adhesions in YAG laser. Methods Twenty-one patients (25 eyes) with chronic post-iris adhesion were treated from April 1996 to December 1998 in our department. Inflammatory reaction was controlled in January. Gentamicin 20000 units and dexamethasone 2mg And atropine 0.3mg, using domestic YAG laser, energy 4.1 ~ 8.1mj, spot diameter 28um, before treatment, trophoblastic embryo point to strengthen mydriasis, accurate focus from the bottom up shot after adhesion. Results Of the 25 eyes, 12 eyes had a round pupil after treatment and another 13 had pupillary defects. The posterior adhesions <3 were completely relieved of posterior adhesions and 3 to 5 were also effective. Conclusion YAG laser posterior iridotomy for the treatment of posterior iridia adhesion is effective.
