目的 :在原板层下巩膜咬切术的基础上进行改进以增加手术成功率.方法 :①扩大巩膜瓣设计面积 (6mm* 6mm) ,加强滤过 ,确保理想的术后眼压 ,防止瘢痕形成.②巩膜瓣采用多线埋藏缝合 ,五针大跨度 ,缝线连接咬切口、巩膜层间、结膜下. 5个线结均放于巩膜瓣下 ,需要一定张力 ,有利于术后前房形成.结果 :通过 79例 96只眼术后两年观察 ,手术成功率为 98 95%.明显高于传统的板层下巩膜咬切手术方法.结论 :该术式术后前房恢复快 ,并发症少 ,结膜滤枕形成好 ,均为生理性滤过泡 ,远期疗效佳 ,值得推广.“,”Objective:We developed sublamina sclera biting operation in order to increase the success rate of operation.Methord:①We extend sclera valve area(6 mm*6 mm),imprest infiltration.insure ideal postoperation eye pressure and prevent scar.②We use multi-thread burial to suture sclera valve with five times of interval suturing.We put the five threads under the sclera valve,it is propitious to hold anterior chamber.Result:79 cases(96 eyes)two-year follow-up after operation tells us that operation success rate is 9895%.The result is higher than traditional sublamina sclera biting operation.Conclusion:This operation has less complications,has quick recovery of anterior chamber,can build gad sclera follicle occipital and fare-period effect is good.
