简介：目的：观察和分析Vogt-小柳原田病（Vogt—Koyanagi—Harada，VKH）葡萄膜炎期多湖状视网膜脱离的光学相干断层扫描（OCT）图像特征。方法：对12例VKH患者24眼进行眼底荧光血管造影（fundusfluoresceinangiography，FFA）和OCT检查。结果：OCT图像可见12例24眼均有视网膜神经上皮浆液性脱离，视网膜下间隔将视网膜神经上皮脱离区分成多个部分。应用激素治疗后，视网膜浆液性渗出吸收，视网膜下的间隔完全消失。结论：VKH治疗前，视网膜下间隔导致VKH多湖状视网膜脱离。

简介：目的：通过光学相干断层扫描（opticalcoherencetomography,OCT）观察视网膜色素变性（retinitispigmentosa,RP）患者黄斑中心凹的厚薄改变及黄斑部图片特点。方法：选取2014-09/2016-09在本院门诊确诊的RP患者74例148眼,同时选取50例100眼正常人作为对照。对两组进行OCT检测和眼底拍照,观察患者视网膜黄斑部位的图像特征,并对患者眼底拍照的结果进行对比,测量黄斑中心凹颞侧面4mm位置、乳头黄斑束中点及黄斑中心凹厚度。结果：对两组研究对象测量视网膜厚度显示,RP患者黄斑中心凹视网膜和中心凹颞侧部4mm厚度与正常人相比,差异无统计学意义（P〉0.05）;RP患者乳头黄斑束中点厚度变薄,与正常人对比差异有统计学意义（P〈0.05）;RP患者黄斑区OCT检测图像表征有5种类型：视网膜黄斑区域水肿者19例38眼;视网膜色素脉络膜毛细血管层和上皮层变薄者18例36眼;视网膜色素上皮层发生萎缩者12例24眼;黄斑部视网膜厚度正常者12例24眼;色素上皮层厚薄表现不一者13例26眼。结论：OCT能在前期及时地发现RP患者黄斑部位的病变,帮助患者深入了解病情发展,为患者早期诊疗提供了临床依据。
