简介：目的比较巩膜外局部加压术与巩膜环扎手术治疗孔源性视网膜脱离的疗效。方法将30眼孔源性视网膜脱离病人随机分A,B两组,A组16眼,采用巩膜外局部加压术;B组14眼采用巩膜环扎手术,术后随访半年至一年,观其视网膜复位和视功能的恢复程度。结果A组13眼视网膜复位顺利,一次手术成功率为81.25%;术后视力提高13眼,不变2眼,下降1眼,出现并发症8眼。B组11眼视网膜一次手术复位,一次手术成功率为78.57%;术后视力提高9眼,不变2眼,下降3眼,出现并发症9眼。两组一次手术成功率、术后视力提高情况、并发症发生率比较.差异无显著性（P〉0.05）。结论巩膜外局部加压术手术治疗RRD是经济,操作简单,并发症较少的理想的手术方法。
