目的探讨孤立性脉络膜血管瘤的吲哚青绿血管造影（ｉｎｄｏｃｙａｎｉｎｅｇｒｅｅｎａｎｇｉｏｇｒａｐｈｙ，ＩＣＧＡ）特征及其临床意义。方法采用眼底彩色照相、眼底荧光血管造影（ｆｕｎｄｕｓｆｌｕｏｒｅｓｃｅｉｎａｎｇｉｏｇｒａ－ｐｈｙ，ＦＦＡ）及ＩＣＧＡ对１０例孤立性脉络膜血管瘤患者的１０只眼进行检查。结果１０只被检查眼中８只眼ＩＣＧＡ能比ＦＦＡ更清晰显示瘤体的范围大小；１０只眼在瘤体显影的１～５秒内均见整个瘤体由不规则脉络膜血管网团组成；１０只眼造影晚期均有特征性的“冲洗现象”；９只眼有瘤体周围的扇形脉络膜灌注不良。结论孤立性脉络膜血管瘤的ＩＣＧＡ特征对诊断与鉴别诊断及指导激光光凝治疗都有重要的临床价值
Objective To investigate the characteristics of indocyanine green angiography (ICGA) in isolated choroidal hemangiomas and its clinical significance. Methods 10 eyes of 10 patients with solitary choroidal hemangioma were examined by fundus fundus photography, fundus fluorescein angiogra-phy (FFA) and ICGA. Results The ICGA of 8 of the 10 examined eyes showed the size of the tumor more clearly than that of the FFA. In 10 eyes, the entire tumor was composed of an irregular choroidal network within 1 to 5 seconds after the development of the tumor. Only the late phase of the ectopic angiography showed a characteristic “flushing phenomenon”; 9 eyes had a fan-shaped choroidal perfusion around the tumor. Conclusion The ICGA features of solitary choroidal hemangioma have important clinical value in the diagnosis and differential diagnosis and guidance of laser photocoagulation
