节段性巩膜外加压手术治疗孔源性视网膜脱离

目的 评价节段性巩膜外加压手术治疗孔源性视网膜脱离的效果。方法 对163例孔源性视网膜脱离患者在间接检眼镜下行视网膜裂孔精确定位，行孔周冷凝、放液、巩膜外加压手术。试验组为不联合巩膜环扎组,共89 例(93 眼);对照组为联合巩膜环扎组,共74 例(76 眼)。术后随访6～9 个月。结果 ①试验组视网膜复位89眼，对照组视网膜复位72眼；②视网膜复位者术后6个月矫正视力：试验组提高82 眼，对照组提高64 眼。结论 节段性巩膜外加压手术治疗孔源性视网膜脱离简化了手术操作，视力预后较好，是一种有效的手术方式。

Segmental scleral buckling surgery for rhegmatogenous retinal detachment

Objective To evaluate the results of segmental scleral buckling surgery for rhegmatogenous retinal detachment. Methods 163 cases of rhegmatogenous retinal detachment from Mar. 2005 to Jan. 2009 were enrolled in the study. Each retinal break was located by indirect ophthalmoscopy.Scleral buckling，cryotherapy and drainage of subretinal fluid procedure were applied. Encircling was used in 93 eyes of 89 patients (the test group) but was not used in 76 eyes of 74 patients (the control group).All patients were followed-up for 6-9 months. Results ①89 eyes in the test group and 64 eyes in the control group got complete retinal reattachment;② postoperative corrected visual acuity improved in 82 eyes of the test group and 64 eyes of the control group. Conclusions Segmental scleral buckling without combining encircling surgery to treat rhegmatogenous retinal detachment simplifies the surgical procedure and has a better visual prognosis. It is an effective surgical procedure.
