摘　　要：目的:分析中心性渗出性脉络膜视网膜病变(central exudative chorioretinopathy,CEC)吲哚青绿血管造影(indocyaninegreen angiography,ICGA)特点。方法:应用海德堡造影系统HRA2对24例24眼CEC患者进行荧光素、吲哚青绿眼底血管造影,并对ICGA与眼底荧光造影(fundus fluorescein angiography,FFA)结果进行对比分析。结果:CEC患者24眼FFA均证实为典型性脉络膜新生血管(choroidal neovascularization,CNV)。ICGA早期,24例CEC可见边界清晰的网状CNV。5例见CNV周围局限性脉络膜血管扩张。ICGA晚期可见CNV处染料渗漏或染色。20眼ICGA早期可见宽窄不一的暗环包绕CNV,4眼未见暗环。ICGA晚期,24眼CNV周围均可见暗环。1例患者光动力(photodynamic therapy,PDT)治疗后2mo,因视力继续下降复查ICGA,可见视网膜脉络膜血管吻合(retinal-choroidal anastomosis,RCA)。结论:由HRA2进行的ICGA对CEC的CNV的结构、边界、局部脉络膜静脉的改变、RCA的显示优于FFA。AIM： To analyze the characteristics of indocyanine green angiography （ ICGA ） in central exudative chorioretinopathy （CEC）. METHODS：A total of 24 cases （24 eyes） with CEC were examined with fundus fluorescein angiography（FFA） and ICGA using Heidelberg retina angiography 2 （ HRA2 ）. The images of ICGA and FFA were analyzed. RESULTS： The choroidal neovascularization （CNV） of CEC was classic CNV confirmed by FFA. In early phase of ICGA, 24 CEC eyes showed a well-defined CNV and 5 eyes showed local dilatation of choroidal vessels around lesion. In the late phase of ICGA, CNV showed dye leakage or staining. In the early phase of ICGA, 20 eyes showed a dark rim around CNV and the other 4 eyes without the dark rim. In the late phase of ICGA, all CEC eyes showed a dark rim around CNV. The repeated ICGA images of a patient with CEC treated by photodynamic therapy （PDT） 2 months ago showed retinal-choroidal anastomosis （RCA）. CONCLUSION ： The structure, border, changes of local choroidal vessels and RCA of CNV were more clearly displayed on ICGA performed by HRA2 than on FFA in patients with CEC.
