目的 观察手术显微镜直视下巩膜扣带术治疗陈旧性视网膜脱离的临床效果.方法 回顾性对36例36眼陈旧性视网膜脱离采用显微镜直视下巩膜外环扎、加压、冷凝、放液等手段治疗对术后并发症视网膜复位情况和视力进行分析.结果 随访6个月以上, 36眼中29眼1次手术达到视网膜解剖复位 (80.5％), 术后矫正视力0.05以上28眼 (77.8％) .结论 手术显微镜直视下巩膜扣带术治疗某些类型的陈旧性视网膜脱离简单有效, 值得临床推广应用.“,”Objective To observe the clinical effect of scleral buckling surgery under surgical microscope in the treatment of old retinal detachment. Methods Retrospective analysis of 36 cases of 36 cases of old retinal detachment under the microscope with scleral buckling, compression, condensation, draining and other means of treatment of postoperative complications of retinal reattachment and visual acuity were analyzed. Results Follow-up 29 of 36 eyes achieved retinal anatomic reduction (80. 5％) in one operation and corrected visual acuity of 0. 05 to 28 eyes (77. 8％) after operation. Conclusion Under the operating microscope, scleral buckling surgery is simple and effective in treating some types of old retinal detachment and is worthy of clinical application.
