Abstract： 目的观察息肉状脉络膜血管病变(polypiodal choroidal vasculopathy, PCV)的临床表现及眼底血管造影特征. 方法回顾分析6例PCV患者7只眼的临床资料及荧光素眼底血管造影(fundus fluorescein angiography, FFA)与吲哚青绿血管造影(indocyanine green angiography, ICGA)检查资料. 结果 PCV患者早期眼底仅可见橘红色病变,随病情进展出现出血、渗出、水肿、浆液性和(或)出血性视网膜色素上皮(retinal pigment epithelium, RPE)脱离,病程长者可出现视网膜、脉络膜萎缩.FFA检查1只眼病变处脉络膜血管网扩张,6只眼见密度不均的斑点状强荧光,造影过程中荧光渗漏,晚期呈强度不均的强荧光片;ICGA检查5只眼早期显示分支状脉络膜血管网,末端扩张呈息肉状,晚期脉络膜血管结构不清,息肉状扩张仍然可辨,7只眼均有形态独特的孤立或簇状分布的息肉状强荧光点,晚期仍有染料存留. 结论 PCV患者眼底可见橘红色病变及出血、渗出和RPE脱离,FFA及ICG检查可见分支状脉络膜血管网及末端息肉状扩张.
