简介:目的:探讨穿透性角膜移植的主要病因、疗效及并发症。方法:回顾性分析2011-01/2013-06于我院行穿透性角膜移植术的患者150例150眼。结果:病因:角膜白斑99眼(66%),角膜变性18眼(12%),角膜溃疡15眼(10%),角膜内皮失代偿10眼(6.7%),圆锥角膜8眼(5.3%)。疗效:植片透明110例(73.3%)。视力≤0.05者42例(28%),0.05〈视力≤0.3者60例(40%),视力〉0.3者48例(32%)。并发症:主要并发症为免疫排斥反应28例(18.7%)。结论:穿透性角膜移植是治疗角膜疾病致盲的重要有效手段,但术后排斥反应仍是影响手术成功的主要因素。
简介:目的方法结果结论分析青光眼小梁切除术后浅前房的原因及治疗效果。对2003年2月-2008年1月126例(138眼)青光眼小梁切除术后浅前房者(37眼)进行回顾性分析。138眼小梁切除手术有37眼(26.81%)发生浅前房,其发生原因有:滤过过强17眼(45.95%),结膜瓣渗漏14眼(37.84%),脉络膜脱离2眼(5.41%),睫状环阻塞性青光眼1眼(2.7%),其它3眼(8.1%)。其中33眼(89.19%)经保守治疗治愈,4眼(10.81%)经前房注射透明质酸钠治疗,使前房形成。青光眼小梁切除术后浅前房发生率较高,大部分经保守治疗可恢复正常,透明质酸钠在前房重建中效果良好。

简介:目的探讨基层医院开展高龄老人白内障超声乳化吸除术应注意的问题,手术难点及处理对策,旨在减少手术并发症,提高成功率。方法对109只眼,75—84岁老人白内障超声乳化吸除术作回顾性总结和分析。结果术后一周视力0.5以上68只眼,占63%。视力0.1—0.3者14只眼,占13%。0.3—0.5者23只眼,占21%。4只眼未脱盲,占3%术中并发症为后囊破裂,未发生核坠入玻璃体,无严重全是并发症发生,术后并发症主要是角膜水肿,未发生大泡性角膜炎。结论本组病例疗效满意。无严重并发症发生。手术成功的关键是要充分了解高龄白内障老人眼部及全身生理特点,对各种手术并发症的原因和表现有清醒的认识,具备扎实的手术操作技巧。
简介:目的:应用频域光学相干断层扫描(opticalcoherencetomography,OCT)对特发性和继发性黄斑前膜(macularepiretinalmembrane,ERM)的形态特征、黄斑中心凹厚度及其与视力的关系进行对比研究。方法:应用频域OCT观察用裂隙灯显微镜、荧光素眼底血管造影(fundusfluoresceinangiography,FFA)及OCT确诊为特发性ERM(92例112眼)、继发性ERM(78例96眼)的患者,观察前膜的形态特征、定量测量前膜及其下视网膜厚度、分析黄斑中心凹厚度与视力的关系。结果:ERM的OCT图像表现为视网膜神经上皮层表面厚薄不一的高反射光带,主要表现为前膜与视网膜内表面出现局灶及大部分粘连,其次表现为黄斑中心凹变浅或消失、神经上皮层增厚、黄斑水肿。特发性ERM患者视网膜平均厚度为398.32±112.07μm,前膜的平均厚度为52.28±9.65μm;继发性ERM患者视网膜平均厚度为416.87±104.17μm,前膜的平均厚度为57.05±10.33μm。两组间的差异无统计学意义(P〉0.05)。在相同视力区间,两组黄斑中心凹厚度比较,差异无统计学意义(P〉0.05)。而分别在两组及同组不同视力区间之间,黄斑中心凹厚度差异有统计学意义(P〈0.05)。结论:OCT可以客观地显示ERM及黄斑部组织结构的改变,并能定量检测ERM、中心凹视网膜厚度变化,是ERM可靠的检测手段。
