目的评价视网膜切开在复杂性视网膜脱离手术中的应用价值。方法回顾性总结了1994年7月至1995年12月在我科做视网膜切开手术的连续病例45例46只眼，其中裂孔性视网膜脱离伴增殖性玻璃体视网膜病变（proliferativevitreoretinopathy．PVR）35例35只眼、外伤性PVRS例8只眼、牵引性视网膜脱离2例3只眼。结果平均追踪7个月，内排液组40只眼一次手术成功24只眼占60％，有12只眼再发视网膜脱离做了第二次同样手术，其中同时取视网膜下膜2眼；取视网膜下膜5只眼和视网膜切开减张3只眼中，有6只眼视网膜复位，失败2只眼。视力改善37只眼占80％。结论在复杂性视网膜脱离中，合理选用视网膜切开、眼内排出视网膜下液、取除视网膜下膜和松解缩短、僵硬的视网膜，可提高手术疗效。
Objective To evaluate the value of retinal detachment in complex retinal detachment surgery. Methods A retrospective review of 45 cases (46 eyes) with retinal detachment in our department from July 1994 to December 1995 were retrospectively reviewed. 35 cases of proliferative vitreoretinopathy (PVR) Only eyes, traumatic PVRS cases in 8 eyes, traction retinal detachment in 2 cases and 3 eyes. Results The average follow-up time was 7 months. In one group, 40 eyes of the intrauterine drainage group were successful in 24 eyes (60%), and 12 eyes underwent repeated retinal detachment for the same surgery In 5 eyes of retina and 3 eyes of retina, 3 eyes retreated and 2 eyes failed. 37 eyes improved visual acuity 80%. Conclusion In the complex retinal detachment, the rational use of retinal incision, intraocular discharge of subretinal fluid, removal of the subretinal membrane and the release of shortened, stiff retina, can improve the surgical effect.
