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。
简介:目的探讨白内障超声乳化摘除及人工晶体植入联合房角分离术治疗闭角型青光眼合并白内障的临床效果方法回顾性分析2009年10月至2011年6月我院收治的闭角型青光眼合并白内障共112例(120眼),应用白内障超声乳化摘除及人工晶体植入联合房角分离术,对房角关闭区域用粘弹剂和手指按压进行钝性分离。观察手术前后的房角及前房变化、视力、眼压及并发症情况,随访6月。结果均经统计学处理。结果120眼手术顺利,术后追踪6月,全部患者术后视力提高,房角开放,中央前房加深,眼压控制良好,手术前后比较差异具有统计学意义。结论超声乳化白内障摘除联合房角分离术是治疗闭角型青光眼合并白内障的有效方法之一,但具体适应证尚待进一步探讨。
