简单孔源性视网膜脱离外路手术后视网膜再脱离原因分析

Clinical analysis of postoperative retinal redetachment of simple rhegmatogenous retinal detachment scleral buckling microsurgery

目的:分析简单孔源性视网膜脱离外路显微手术后视网膜再脱离的主要原因,根据这些原因采取有效的预防措施,提高手术的成功率。方法:对15例15眼简单孔源性视网膜脱离外路显微手术后视网膜再脱离的患者进行分析,查找视网膜再脱离的主要原因。所有视网膜再脱离患者增生性玻璃体视网膜病变(PVR)≤B级。结果:术后随访1a,简单孔源性视网膜脱离外路显微手术后视网膜再脱离15例15眼患者中,出现新裂孔7眼(46.7%);原裂孔未能封闭4眼(26.7%);遗漏裂孔2眼(13.3%);脉络膜脱落1眼(6.7%);PVR1眼(6.7%)。结论:简单孔源性视网膜脱离外路显微手术后视网膜再脱离的主要原因为:出现新裂孔、原裂孔未能封闭、遗漏裂孔。

AIM：To analyze principal causes of postoperative retinal re-detachment of simple rhegmatogenous retinal detachment（RRD） scleral buckling microsurgery in order to take effective measures and improve the success of surgery.METHODS：Fifteen cases（15 eyes） of postoperative retinal re-detachment of simple RRD Scleral Buckling microsurgery were studied to search for principal cause of retinal re-detachment.Then a conclusion was drawn that PVR was under B／[1／]in all retinal re-detachment cases.RESULTS：In post operative follow-up of 1 year,new split pore took place in 7 eyes（46.7%）.Original split pore was not closed in 4 eyes（26.7%）.Missing hole was in 2 eyes（13.3%）.Detachment of choroid was in 1 eye（6.7%） and PVR was in 1 eye（6.7%）.CONCIUSION：Principal causes of retinal re-detachment under Scleral Buckling microsurgery of RRD include new split pore,unenclosed original split pore and missing hole.
