    摘 要:目的 观察中心性浆液性脉络膜视网膜病变(CSC)的吲哚青绿血管造影(ICGA)和荧光素眼底血管造影(FFA)特征，以探讨该病的发病机制. 方法 用Heidelberg共焦激光扫描眼底血管造影仪(HRA)对48例CSC患者(96只眼)进行ICGA和FFA. 结果 全部受检眼中，ICGA都可见造影早期脉络膜有因为动脉充盈延迟而表现的局限性暗荧光区.在造影中晚期，原充盈延迟区内的脉络膜可因通透性增强而有高荧光表现，或者因毛细血管小叶缺血而表现的斑片状低荧光;其相应部位的色素上皮(RPE)在FFA过程中则表现为渗漏或萎缩.此外，在7只眼中，可见脉络膜涡静脉分支扩张及渗漏. 结论 脉络膜静脉及毛细血管瘀血可能是导致FFA中RPE渗漏的原因.
