目的探讨显微镜直视下孔源性视网膜脱离巩膜外加压术治疗孔源性视网膜脱离的临床疗效。方法采用间接检眼镜和三面镜诊断孔源性视网膜脱离50例(50眼)。术中利用显微镜直视对裂孔及变性区进行精确定位,用810nm激光对视网膜裂孔周围进行环形凝固,并行巩膜外垫压术。结果术后随访1～6个月,裂孔封闭,视网膜完全复位48例(48眼),手术成功率达96%。结论显微镜直视下视网膜裂孔光凝巩膜外加压术具有疗效确切、操作简便、术野清晰、定位准确、污染机会少和手术并发症少等优点,较其他术式更易在我国基层医院中推广应用。
Objective To investigate the clinical efficacy of rhegmatogenous retinal detachment with rhegmatogenous retinal detachment under scleral microscope. Methods 50 cases (50 eyes) of rhegmatogenous retinal detachment were diagnosed by indirect ophthalmoscope and three-facet mirror. Intraoperative use of microscope for accurate positioning of the hole and degeneration of the fracture zone, with 810nm laser ring around the retinal ring coagulation, scleral buckling surgery. Results The patients were followed up for 1 to 6 months. The holes were closed and the retina was completely reset in 48 cases (48 eyes). The successful rate of operation was 96%. Conclusions Under microscope, retinal hole photocoagulation and scleral buckling have the advantages of definite curative effect, simple operation, clear operative field, accurate positioning, fewer chances of contamination and fewer complications. They are more easily used in primary hospitals in our country application.
