简介:目的对改良翼状胬肉手术方法进行安全性评估的研究。方法188例翼状胬肉患者随机分为实验组和对照组。实验组接受改良方法进行翼状胬肉手术。对照组按照《眼科手术图谱》传统翼状胬肉切除术方法进行手术。记录所有患者手术时间、术后角膜上皮修复时间。术后每周随访,记录术后1周、2周、3周、4周时结膜充血情况及结膜充血完全消退时间。随访3个月,记录发生角巩膜溃疡、结膜肉芽以及翼状胬肉复发的病例数。结果实验组有96人完成随访,对照组有92人完成随访。实验组患者角膜上皮修复时间为2.42±0.68天,对照组为4.27±1.05天,P〈0.05,差别有统计学意义;实验组结膜充血评分术后1周、2周、3周、4周时分别为3.31±0.47、2.76±0.74、1.89±0.860.94±0.70,对照组分别为3.84±0.37、3.58±0.67、2.93±0.71、1.85±0.78,两两比较P〈0.05,差别有统计学意义。结膜充血消退时间实验组为5.15±0.92周,对照组为7.20±1.08P〈0.05,差别有统计学意义。实验组未发生结膜肉芽,对照组为14例,P〈0.05,差别有统计学意义。实验组发生角巩膜溃疡4例、复发4例,对照组为7例、5例,P〉0.05,差别无统计学意义。结论改良的翼状胬肉手术方法在术后角膜上皮修复时间、术后结膜充血程度、结膜充血消退时间、结膜肉芽发生率上忧于传统手术方法,差别有统计学意义。在角膜溃疡发生率、翼状胬肉复发率上改良手术方法与传统手术差别无统计学意义。
简介:目的探讨两种不同手术方式治疗翼状胬肉对泪液功能的影响及影响因素。方法选取翼状胬肉患者40例(40只眼)随机分成两组:A组20个病人(20只眼)翼状胬肉切除联合冻干羊膜移植术;B组20+病人(20只眼)翼状胬肉切除联合带自体角膜缘干细胞结膜瓣移植术。术前,术后1mo,术后3mo行泪膜破裂时间(BUT)、泪液分泌试验(SchirmerI)、角膜荧光素染色(CSF),评价翼状胬肉及翼状胬肉切除术后泪膜功能变化对患者生活质量的影响。结果两组病人术后lmoBUT缩短,角膜荧光素染色增多,差异有统计学意义(P〈0.05),而术后SchirmerI与术前相比无统计学意义,两组术后3moBUT,SchirmerI,CFS与术前相比无统计学意义,翼状胬肉切除联合带自体角膜缘干细胞结膜瓣移植术组术后早期泪膜稳定性优于翼状胬肉切除联合冻干羊膜移植术,差异具有统计学意义∞〈0.05)。结论翼状胬肉切除术早期对泪膜功能有影响。翼状胬肉切除联合带自体角膜缘干细胞结膜瓣移植术早期对泪膜的影响小于翼状胬肉切除联合冻干羊膜移植术。

简介:目的观察两种不同手术方式治疗泪小管断离的临床疗效。方法在住院治疗的泪小管断离共60例(60眼),随机分为两组:A组30个病人(30只眼)硬膜外麻醉导管治疗泪小管断离;B组30个病人(30只眼)crawford管治疗泪小管断离。根据病情平均3-6个月拔管,拔出泪道硅胶管后,泪道冲洗通畅且无症状为治愈;泪道冲洗通畅,但有一定阻力且偶有流泪为好转;泪道冲洗不通畅为无效;拔管两个月以上再次流泪冲洗不通畅为复发。结果拔管后,A组:治愈:18眼(60%);好转:6眼(20%);无效:4眼(13.33%);复发:2眼(6.67%)。B组:治愈:26眼(86.67%);好转:2眼(6.67%);无效:1眼(3.33%);复发:1眼(3.33%)。结论鼻内窥镜下crawford管置管是一种有效的治疗泪小管断离的办法。

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。
