目的 观察中心性浆液性脉络膜视网膜病变 (central serous chorioretinopathy,CSC)的吲哚青绿血管造影 (indocyanine green angiography,ICGA)特征。 方法 用共焦激光扫描眼底血管造影仪对 70例 CSC患者进行荧光素眼底血管造影 (fundus fluorescein angiography,FFA)与 ICGA同步检查。 结果 79只眼 FFA检查有视网膜色素上皮 (retinal pigment epithelium,RPE)渗漏。 ICGA检查 2 3只眼的脉络膜血管充盈迟缓 ;79只患眼有脉络膜血管扩张充血 ;78只眼的 RPE渗漏处有脉络膜血管的通透性增高 ;2 7只对侧健眼有同样的改变 ;19只患眼和 6只健眼有 RPE脱离 ;2 1只眼有 RPE的色素脱失、萎缩和 /或带状萎缩。 结论 脉络膜血管异常是 CSC的基本 ICGA特征。
Objective To observe the characteristics of indocyanine green angiography (ICGA) in central serous chorioretinopathy (CSC). Methods Seventy CSC patients underwent fundus fluorescein angiography (FFA) and ICGA were examined synchronously with confocal laser scanning fundus angiography. Results In 79 eyes, FFA showed retinal pigment epithelium (RPE) leakage. In ICGA examination, choroidal vessels were slow to fill in 23 eyes, choroidal vasodilation and congestion in 79 eyes, increased choroidal vascular permeability in RPE at 78 eyes, and similar changes in 27 contralateral eye ; RPE detachment in 19 affected eyes and 6 healthy eyes; pigmentation, atrophy and / or atrophy of RPE in 21 eyes. Conclusion Choroidal vascular abnormalities are the basic ICGA features of CSC.
