简介:手法小切口白内障术(manualsmallincisioncataractsurgepy,MSICS)特别是在发展中国家已广泛应用于临床手术。本文旨在比较传统白内障囊外摘除术(extracapsularcataractextraction,ECCE)、MSICS以及超声乳化白内障吸除术治疗效果以及安全性(术中并发症以及术后并发症)。通过使用PubMed搜索引擎,我们收集了传统ECCE、MSICS以及超声乳化白内障吸除术的相关文献,以评价其安全性和治疗效果。同时,也参考了国内出版的相关文献。结果发现,与超声乳化白内障吸除术相比,传统ECCE以及MSICS也取得了很好的治疗效果,并且具有并发症少等优点。MSICS不需要依赖昂贵的仪器,并且具有手术快速、费用低廉以及技术门槛低等特点,特别适用于硬核白内障的治疗。虽然在白内障手术治疗过程中MSICS需要一定的技术和耐心,但它仍然是一种安全、有效、经济治疗手段,特别是在发展中国家可以替代超声乳化进行白内障的治疗。
简介:目的了解531例患者(含家属)对我院民生工程白内障手术疗效的评价。方法我院固定1名眼科主治医师在不同时间段进行电话回访(含手机),如固定电话打不通再换手机打,打1-2次通话者为1次打通,3次(含3次者)以上为多次打通,打4-7次不通者放弃。结果531例共打电话1327次,平均每名患者2.49次,回访率为100%,最终获得有效通话者427例,回访成功率为80.41%。手术满意380例,占88.99%;基本满意33例,占7.73%;满意率为96.72%。不满意14例,占3.28%。术后复查1-3次者314例,占73.53%;未复查93例,占21.77%;不知道是否复查20例,占4.68%;复查率最高者琅琊区100%,最低者定远县63.44%。无1例在住院手术期间花钱。未发现严重并发症和医疗事故及医疗纠纷。结论电话回访能有效获得民生工程白内障手术患者的疗效评价,且经济方便,应纳入常规内容。

简介:目的研究分泌性中耳炎(SOM)患者与正常人相比,声导抗各值的差异及与纯音听阈的关系。方法回顾分析我科2008年1月~2013年6月收治的120例(162耳)SOM患者的声导抗和纯音测听资料,并将声导抗各项指标、纯音听阈测试结果与正常对照组作比较。将能抽出液体和不能抽出液体者进行上述指标比较。结果SOM患者声导抗测试鼓室压、声顺值和Grad明显低于正常组,TW明显高于正常组(P〈0.05),耳道容积差异无统计学意义(P〉0.05)。能抽出液体和不能抽出液体组,声导抗各指标差异无统计学意义(P〉0.05)。SOM患者纯音听阈频率分布差异有统计学意义(P〈0.05)。听力是否出现障碍除TW外,其余指标差异均无统计学意义。结论声导抗测试鼓室压、声顺值、Grad和TW有助于诊断SOM。鼓室压、声顺值、Grad和TW的值的大小不能为鼓室有否积液提供依据。SOM患者有听力下降,以高频听力下降为主,可以通过声导抗中TW指标的大小,估计听力是否受损。
简介:目的:探讨机械性眼外伤的临床特征及诊疗结果分析。方法:收集我院收治的机械性眼外伤122例122眼的临床资料,进行记录及回顾性分析。结果:机械性眼外伤122例中,开放性眼外伤116眼(95.1%),闭合性眼外伤6眼(4.9%),男女之比6.18∶1,机械性眼外伤以眼球开放性损伤为最多,致伤多以异物为主,经过及时手术治疗,全部保住了眼球,与入院视力相比,出院视力得到明显提高。结论:工作和生产意外是机械性眼外伤的主要原因,病情复杂,合并症多,后果严重,应加强防范。及时的医院就诊和眼科显微手术技术的提高及玻璃体视网膜手术的开展是挽救伤眼视力、降低机械性眼外伤并发症的有效措施。
简介:目的:比较波前像差仪与主观验光法对屈光度检查的结果,探讨波前像差仪对低阶像差测量的可靠性和准确性。方法:对2007-07/2007—10在我院拟行准分子激光角膜屈光手术的患者88例168眼,分别使用以Hartmann—Shack原理为基础设计的德国蔡司WASCA波前像差仪分析系统以及主观插片验光方法进行检查,并对近视球镜、近视柱镜、散光轴向的结果比较、分析。结果:波前像差仪与主观验光测量的屈光度较为接近,等效球镜度分别为_6.53±1.64D和_6.44±1.89D;近视球镜度分别为-5.93±1.65D和-5.83±1.80D;近视柱镜度分别为-1.22±0.66D和-1.27±0.70D;散光轴向度分别为110.67±75.69°和119.24±74.21°;四组数据的统计学分析均无显著性差异(P〉0.05)。结论:波前像差仪在无需散瞳的情况下能够较为准确地反映眼屈光度的情况。
简介:目的研究非接触式角膜内皮镜中参与分析的细胞数(NC)对测量结果重复性的影响。方法收集2011年3月至2016年3月到我院诊治并在同一时间行2次以上(含2次)非接触式角膜内皮镜测量的患者,其测量结果包括中央角膜厚度(CCT)、内皮细胞密度(ECD)、平均细胞面积(ACS)、细胞面积变异系数(CV)和六边形细胞百分比(HEX%),排除NC=0的结果,〉2次测量的患者,选择NC最大的2组结果,以每位患者所得的2组结果中NC较小者(NCmin)为分组依据,10个细胞为一个等级,获得(NCmin〈10、10~20……90~100、≥100)11个组段,采用组内相关系数(ICC)及其95%置信区间(95%CI)对各组段内2组数据的重复性进行评估,并对ICC进行F检验,检验水准α=0.05。结果各组段CCT的ICC均〉0.9,且95%CI下限在0.75以上;ECD和ACS的ICC,当NC≥100时,均〉0.9,且95%CI下限在0.75以上,当NC≥50时,均〉0.75;CV的ICC,当NC≥90时,〉0.75,其余组段均〈0.75;HEX%的ICC,当NC≥100时,〉0.75,其余组段均〈0.75。结论CCT测量结果的重复性不受NC限制;分析ECD和ACS时,NC应在50以上,当NC≥100时,测量结果的重复性最佳;分析CV和HEX%时,NC应分别在90和100以上。
