简介:目的:分析最小量节段性外垫压手术治疗复杂原发性视网膜脱离的效果和手术并发症。方法:回顾性分析2006-10/2008-10在西安市第四医院眼科住院的、接受最小量节段性外垫压术治疗的连续的复杂原发性孔源性视网膜脱离76例。复杂原发性孔源性视网膜脱离限定为裂孔位于两个及两个以上象限,玻璃体视网膜病变分级在C1~C2。最小量节段性外垫压术是指仅限于裂孔区的节段性外垫压,联合前房穿刺放房水,术后裂孔周围激光凝固。分析其发病年龄、病程、手术前后视力、视网膜脱离范围、裂孔数目、裂孔形态、一次手术复位率、再次手术复位率、再次手术率及术后并发症,并行统计学处理。结果:患者发病年龄平均31.92(19~62)岁,平均病程为7.40(2.0~36.5)mo,视网膜脱离象限平均为3.33个,平均裂孔数量为3.43(2~7)个。手术后视力提高的患者为48例,一次手术复位率是84%(64/76);再次手术复位率是93%;再次手术率为38%。术后并发症包括:术后短期复视3例,短期高眼压12例,黄斑水肿2例,共17例。结论:和文献资料比较,以最小量手术治疗复杂原发性视网膜脱离可以取得与环扎手术同样的解剖及功能复位,但是再次手术率较高。强调手术适应证选择的重要性。
简介:目的探讨表而麻醉下小切口囊袋内圈垫式切核白内障囊外摘除术的手术疗效。方法表面麻醉下对116眼(96例)白内障行小切口囊袋内圈垫式切核白内障摘除术,记录术中患者眼疼痛情况及手术时间,术后角膜水肿情况、最佳矫正视力及手术并发症。结果116眼手术均在表面麻醉下完成,术中疼痛分级情况:0级96眼,1级14眼,2级6眼,3级0眼。手术平均时间为13.6±3.5min。术后第1天最佳矫正视力情况:0.2-0.4者16眼,0.5-0.8者82眼,≥1.0者18眼。术后第一天角膜水肿情况:角膜内皮纹样水肿28眼,均于术后3天左右消退;局部斑片样混浊3眼,术后1周内消退。结论表面麻醉下小切口囊袋内圈垫式切核白内障摘除术具有术中操作简便,手术时间短,前房操作空间大,并发症少等优点。
