目的:观察巩膜扣带术治疗陈旧性孔源性视网膜脱离的疗效。方法:陈旧性孔源性视网膜脱离患者12例12眼,术前均在裂隙灯下用三面镜进行裂孔定位,术中均在显微镜下行巩膜扣带术,按术前裂孔的定位预置巩膜缝线,放出黏稠视网膜下液,冷凝封闭裂孔,预置缝线下植入硅胶,根据病情,部分患者植入环扎带,结扎缝线固定。术后随访,观察视网膜复位情况。结果:本组病例初次手术视网膜解剖复位率100%。结论:巩膜扣带术对于部分陈旧性孔源性视网膜脱离可以取得较好的效果。

AIM:To observe the therapeutic effect of scleral buckling procedure for old retinal detachment. METHODS:Totally 12 patients 12 eyes with old retinal detachment preoperatively were under slit-lamp,using three mirrors to locate the retinal breaks,performed scleral buckling under the microscope.According to the preoperative position of the breaks pre-scleral suture was set,viscous subretinal fluid was drained,retinal breaks closed by croytherapy,silicone implanted under prescleral suture,and some patients combined with encircling band,ligated scleral suture to fixation.Patients were followed up to observe the retinal reattachment. RESULTS:The initial surgical retinal reattachment rate was 100%in all patients. CONCLUSION:Reattachment of retina can be achieved in some patients with old retinal detachment who undergo simple scleral buckling procedure.
