摘要 目的观察视网膜分支静脉阻塞继发黄斑水肿(BRVO-ME)患眼脉络膜厚度及血流灌注变化特征。方法回顾性纳入2022年10-11月在金华市中心医院就诊的病程≤1个月且未经治疗的BRVO-ME患者22例22眼,同时纳入年龄、性别匹配的健康对照者20名20眼。采用SS-OCTA扫描所有受检者的黄斑区视网膜及脉络膜,获取图像,测量黄斑中心凹厚度(CMT)、中心凹下脉络膜厚度(SFCT)、脉络膜毛细血管密度、脉络膜中大血管密度及脉络膜血管指数(CVI)。比较BRVO-ME患眼与正常对照眼间参数的差异。结果BRVO-ME眼与正常对照眼CMT分别为(404.36±82.71)μm和(282.80±20.14)μm,SFCT分别为(283.05±70.45)μm和(241.40±58.05)μm,脉络膜毛细血管密度分别为(18.68±5.63)%和(13.8±5.41)%,脉络膜中大血管密度分别为(69.59±2.68)%和(67.95±1.90)%,CVI分别为(52.05±5.56)%和(47.00±5.50)%。BRVO-ME眼CMT、SFCT、脉络膜毛细血管密度、脉络膜中大血管密度、CVI均大于正常对照眼(均P<0.05)。结论BRVO-ME眼黄斑区脉络膜较正常人增厚,脉络膜血管密度增加,脉络膜血管存在扩张。
