目的:观察巩膜扣带术治疗陈旧性视网膜脱离的效果。方法:选取38例38眼陈旧性视网膜脱离患者,术中直视下定位、冷凝视网膜裂孔。针对不同病例36眼于裂孔处缝合硅海绵(其中19眼加缝硅胶环扎带),另2眼单纯行环扎术。26眼进行了视网膜下液引流术,7眼在手术前、后联合了激光光凝术。结果:其中33眼单次手术视网膜解剖复位,首次手术复位率87%,2眼再次手术后复位,手术最终解剖复位率92%。术中及术后无严重并发症发生。结论:通过个体化设计手术方案,巩膜扣带术治疗伴有视网膜下增生的陈旧性视网膜脱离可获得较高的手术治愈率。

AIM:To discuss the therapeutic effect and surgical indication with scleral buckling for long-standing retinal detachment. ·METHODS:The major surgery was as follows:retinal breaks locating,cryotherapy,scleral buckling or encircl-ing scleral buckling. Thirty-eight patients 38 eyes with long-standing retinal detachment accepted surgery,including thirty-six eyes in scleral buckling among which nineteen eyes encircling scleral buckling and silicone encircling,and two eyes underwent encircling scleral buckling merely. Among these cases twenty-six eyes underwent subretinal fluid drainage and seven eyes combined with 532 nm laser photocoagulation. ·RESULTS:The rate of retinal reattachment after one surgical procedure was 87% and after two procedures was 92%. And there were no serious complications occurred in operation and postoperation. ·CONCLUSION:Scleral encircling and buckling proce-dures can be used effectively to treat selected cases of long-standing retinal detachment,and the choice of operation should be individualized for each patient.
