【摘要】 目的 探讨一种从周边部视网膜裂孔剥离视网膜下膜的新技术。方法 连续10例伴有视网膜下增生的裂孔性视网膜脱离和外伤性视网膜脱离患者，采用标准经睫状体平部三通道玻璃体切除术，利用上方2个睫状体平部穿刺孔附近的周边部视网膜裂孔，或直接从锯齿缘区视网膜插入视网膜剥离钩或显微钳，分离和取出视网膜下膜。结果 利用上方11点裂孔1例、利用锯齿缘视网膜裂孔8例和直接从10点锯齿缘视网膜插入眼内器械1例。从10点方位视网膜裂孔，剥离视网膜下膜范围可达6～3点，在2点方位，剥膜范围可达到9～6点。顺利取出视网膜下膜8例;钩断粘连松解收缩2例。并发症主要是医源性视网膜裂孔2例。随访平均28个月，全部病例视网膜最终解剖复位。结论 从周边部视网膜裂孔剥离视网膜下膜范围广泛，切口容易封闭，可减少后极部剥膜的并发症。

    【Abstract】 Objective To introduce a newtechnique of peeling subretinal membrane(SRM)through a peripheral retinal break(RB).Methods 10patients with consecutive rhegmatogenous and traumatic retinal detachment were enˉrolled in this study.The standard three port pars plana vitrectomy was performed.The RBs available was always periphˉeral ones near two superior sclerectomy sites or formed through inserting peeling hook or microforceps at the ora serrata to separate and peel SRM.Results Peeling-SRM was performed through the RB at11o’clock hour in1case and the RBs near ora serrata in8cases ......
