  • 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。
