简介：目的：评价聚乙二醇滴眼液联合重组牛碱性成纤维细胞生长因子滴眼液治疗干眼症的疗效。方法：干眼症患者51例102眼，双眼自身对照，随机分为治疗组和对照组。治疗组给予聚乙二醇滴眼液和重组牛碱性成纤维细胞生长因子滴眼液，均4次／d，两种滴眼液之间间隔5～10min。对照组给予聚乙二醇滴眼液滴眼，4次／d，连续用药1mo后复查。观察每组用药前后SchirmerI试验，BUT，角膜荧光素染色和症状改善情况。结果：两组治疗前后BUT，角膜荧光素染色和症状都有显著差异（P〈0．05）。两组治疗前后SchirmerI试验结果无显著差异（P〉0．05）。治疗后两组BUT，角膜荧光素染色和症状也有显著差异（P〈0．05）。结论：聚乙二醇滴眼液联合重组牛碱性成纤维细胞生长因子滴眼液对治疗干眼症有明显的疗效。

简介：目的：利用频域三维相干光学断层扫描（threedimensionalfrequencydomaincoherentopticaltomography,3D-OCT）评估准分子激光原位角膜磨镶术（laserinsitukeratomileusis,LASIK）对视网膜神经纤维层厚度（retinalnervefibrelayerthickness,RNFLT）的影响。方法：对83例83右眼接受LASIK治疗的受试者分别于术前及术后1d;1wk;1,3mo行3D-OCT检查,测量视乳头上方、下方、鼻侧、颞侧及12个钟点位RNFLT,利用重复测量方差分析及配对t检验对术前及术后的数据统计学处理。结果：术前及术后各时间点行重复测量方差分析显示,视乳头下方、颞侧、5：00～11：00位RNFLT均值无显著差异（P〉0.05）,而视乳头上方、鼻侧、1：00～4：00位、12：00位RNFLT有显著差异（P〈0.05）;进一步对术前及术后各时间点视乳头上方、鼻侧、1：00～4：00位、12：00位RNFLT分别行配对t检验得出,术后1d时视乳头上方、鼻侧及1：00～4：00位、12：00位RNFLT较术前变薄,差异有统计学意义（P〈0.05）,术后1wk;1,3mo时以上各方位RNFLT较术前比较均无统计学差异（P〉0.05）。同时表明RNFLT变薄与屈光度及激光时间成正相关。结论：LASIK术后早期上方及鼻侧RNFLT变薄,但术后1wk恢复至正常水平,LASIK手术对RNFLT无长远影响。
