简介:目的:分析抗血管内皮生长因子(VEGF)药物加Ahmed青光眼引流阀(AGV)对新生血管性青光眼(NVG)的疗效和安全性。方法:选取2020.01-2020.11本院收治的NVG患者10例为研究对象,均通过抗VEGF药物加AGV开展治疗,观察术后不同时间的手术成功率;术前及术后不同时间的眼压水平、视力改变、视功能受损眼病患者生活质量评定量表(QOL)评分和并发症情况。结果:术后1d及1周,手术成功率达到100.00%,后伴随时间延长有轻微下降,但术后不同时间的手术成功率相比无显著差异(P>0.05)。术后1d及1周,眼压水平较术前显著下降(P<0.05),至术后1个月眼压有轻度升高,但仍低于术前(P<0.05),术前及术后眼压水平相比差异显著(P<0.05)。术后1d及1周,视力提升比例达到100.00%,术后1个月开始有轻微下降,但术后不同时间的视力水平相比无显著差异(P>0.05)。术后,患者QOL评分术前显著升高(P<0.05),至术后1个月QOL评分有轻度下降,但仍高于术前(P<0.05)。10例患者中1例出现前房少量出血,1例出现轻度角膜水肿,均未经特殊处理后自行消失,无1例出现严重并发症。结论:抗VEGF加AGV对NVG患者疗效确切,能改善其视力,降低其眼压水平,且安全性较高,值得采用。

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。
