简介:目的对马凡综合症伴晶状体半脱位患者行超声乳化吸除联合人工晶体植入合并张力环植入或超声乳化吸除联合人工晶体悬吊两种手术方法的探讨和分析.方法对3例(3眼)合并晶状体半脱位(脱位范围<1/2象限)的患者行超声乳化吸除联合人工晶体植入合并张力环植入术;对10例(11眼)合并晶状体半脱位(脱位范围>1/2象限)的患者行超声乳化吸除联合人工晶体悬吊术,分析手术前后视力及并发症.结果随访3-24个月,13例患者视力有不同程度的提高,未发生视网膜脱离及葡萄膜炎等并发症.结论超声乳化吸除联合人工晶体植入合并张力环植入或超声乳化吸除联合人工晶体悬吊术是进行马凡综合症晶状体半脱位治疗的有效手术方式,临床应根据晶状体脱位情况的不同选择不同的手术方式.
简介:目的:在高度轴性近视眼与正常眼轴眼之间作对比分析,观察眼轴长度与白内障超声乳化加人工晶状体(intraocularlens,IOL)植入手术风险的相关性。方法:回顾性分析2012-02/2013-02在我院行白内障超声乳化加IOL植入术的连续病例843例1042眼。正常眼轴组(21~24mm)853眼,高度轴性近视组(≥26mm)189眼。对比分析两组的眼内并发症,包括玻璃体脱失,后囊膜破裂,晶状体核掉入玻璃体腔和IOL位置异常。结果:年龄在两个组中都是眼内并发症的风险因素,年龄的增长与眼内并发症的发生呈正相关,眼轴长度与眼内并发症的发生呈正相关,尤其对于后囊膜破裂和玻璃体脱失两个并发症。结论:此项研究结果提示,年龄和眼轴长度是白内障超声乳化手术并发症发生的两个风险因素,了解这些风险并提前做好准备可能会降低并发症的发生。

简介:目的研究高纤维蛋白原血症在突发性耳聋发病中的作用.方法40例诊断明确、发病在7d以内的患者为研究对象(共49只耳),42例正常健康人作为对照组,分别对其血液流变学、血生化、全血细胞计数、凝血功能作检测,检测结果输入SPSS软件作处理进行统计学分析.结果突发性耳聋患者纤维蛋白原水平、红细胞聚集指数、血浆粘度明显高于对照组;差异有显著统计学意义(P<0.05),血浆凝血酶原时间、白陶土部分凝血活酶时间明显短于对照组,差异也有显著统计学意义(P<0.05),血生化和全血细胞计数无明显统计学意义(P>0.05).结论血浆纤维蛋白原水平的提高可能是突发性耳聋血管性病因中的主要因素.
简介:目的探讨用改良圈匙娩核并注重粘弹剂应用对防止小切口非超声乳化白内障囊外摘出人工晶体植入术并发症的作用。方法用改良圈匙娩核并注重粘弹剂应用对355例白内障行小切口非超声乳化白内障人工晶体植入术。结果术后三天矫正视力≥0.5者291眼达82%,脱残339眼(95.5%)脱盲315眼(98.9%)。术后角膜水肿39眼,占10.98%均在3~6天后恢复透明。后囊破裂7眼,占1.97%,前房出血4眼,占1.13%。瞳孔轻度变形10眼,占2.8%,暂时性高眼压4眼,占1.13%。结论在行小切口白内障囊外摘出人工晶体植入时,应用改良后的圈匙娩核并注重粘弹剂应用,就会明显减少并发症,达到良好的效果。
简介:目的:系统评价拉坦前列素(Latanoprost)滴眼液与噻吗心安(Timolol)滴眼液降眼压的有效性和安全性。方法:计算机检索PubMed,Medline,CNKI及中国生物医学文献数据库收录的,并辅以手工检索、因特网搜索的有关拉坦前列素与噻吗心安治疗原发性开角型青光眼和高眼压症的随机对照试验(RCT)。按照纳入和排除标准限定研究对象,通过Jadad评分量表进行文献质量评估后,针对眼压下降比例、药物不良反应2项内容,使用Cochrane协作网提供的RevMan5.0软件进行Meta分析。结果:共纳入9项RCT,合计555例患者。Meta分析结果显示:(1)拉坦前列素滴眼液与噻吗心安滴眼液降眼压效果,在2,6,12wk时差异均有统计学意义(P<0.01),加权平均差(WMD)分别为:在2wk[WMD=-0.76,95%CI(-1.32,-0.20)],在6wk[WMD=-1.15,95%CI(-1.68,0.63)]和12wk[WMD=-1.01,95%CI(-1.42,-0.61)]。(2)随访结束时,结膜充血、异物感为拉坦前列素的两种较为常见的不良反应,但其发生率拉坦前列素组与噻吗心安组比较,结膜充血的发生率[OR=2.25,95%CI(0.99,5.08)],异物感的发生率[OR=2.48,95%CI(1.02,6.03)],显示二者差异均无统计学意义。结论:治疗原发性开角型青光眼和高眼压症,拉坦前列素降眼压效果在用药12wk内较噻吗心安好;两者在12wk内引起结膜充血、异物感、虹膜色素加深、视野损害等的不良反应方面,差异不明显。由于纳入研究的样本量偏小,且方法学质量中等,致使本系统评价结果论证强度不高,因此还需要开展更多的高质量的临床随机对照研究,以便更客观、准确、全面地评价其疗效和安全性。
