Abstract： 目的观察中国人息肉状脉络膜血管病变(polypoidal choroidal vasculopathy, PCV)的眼底表现及眼底血管造影特征. 方法分析经眼底彩色照相、荧光素眼底血管造影(fundus fluorescein angiography,FFA)及吲哚青绿血管造影(indocyanine green angiography,ICGA)检查确诊的PCV患者42例48只患眼的眼底图像资料. 结果 PCV患眼眼底最常见表现为斑片状视网膜下出血,占72.9%;其次是黄白色渗出,占27.1%;仅14.6%的患眼于后极部可见特征性的视网膜下结节样橘红色病灶;54.2%的患眼有出血性或浆液性视网膜色素上皮脱离(pigment epithelium detachment, PED).75.0%的患眼显示有异常分支的脉络膜血管网及其末梢的息肉状扩张灶;25.0%的患眼见多个息肉状脉络膜血管扩张灶而无明显的分支状脉络膜血管网与之相连.62.5%的息肉状病灶位于黄斑区;12.5%的息肉状病灶在血管弓区;6.3%的息肉状病灶位于视盘旁区;18.8%的息肉状病灶在上述2个部位同时存在. 结论中国人PCV患眼眼底最常见表现为视网膜下出血,大部分患眼存在PED. PCV好发部位为黄斑区及血管弓区,大部分患眼ICGA可见特征性的脉络膜血管网及其末梢的息肉状扩张灶.
