To analyze indocyanine green angiography (ICGA) features in one case of diffuse choroidal hemangioma associated with Sturge-Weber syndrome.
Color fundus photography, fluorescein angiography (FA) and ICGA were performed in a patient with diffuse choroidal hemangioma associated with Sturge-Weber syndrome.
The diffuse choroidal hemangioma was not identified by FA. ICGA revealed that the vascular tissue of the diffuse hemangioma filled rapidly with dye during the arterial phase of the choroidal angiogram; copious dye leakage appeared early and persisted into the late phase of angiography. Late "wash-out" phenomenon was not observed 30 minutes after dye injection. Sectors of reduced choroidal perfusion in the upper or lower half of the midperiphery were present.
ICGA may be an important and sensitive technique in detecting the diffuse choroidal hemangioma associated with Sturge-Weber syndrome.
分析1例与斯-韦综合征相关的弥漫性脉络膜血管瘤的吲哚青绿血管造影（ICGA）特征。
对1例与斯-韦综合征相关的弥漫性脉络膜血管瘤患者进行彩色眼底照相、荧光素血管造影（FA）和ICGA检查。
FA未发现弥漫性脉络膜血管瘤。ICGA显示，在脉络膜血管造影动脉期，弥漫性血管瘤的血管组织迅速充盈染料；造影早期出现大量染料渗漏，并持续至造影晚期。注射染料30分钟后未观察到晚期“洗脱”现象。中周部上半或下半存在脉络膜灌注降低区域。
ICGA可能是检测与斯-韦综合征相关的弥漫性脉络膜血管瘤的一项重要且敏感的技术。
