孤立性脉络膜血管瘤的吲哚青绿血管造影

目的 探讨孤立性脉络膜血管瘤的吲哚青绿血管造影(indocyanine green angiography,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(fundus fluorescein angiography,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。(中华眼底病杂志,1998,14:81-83)

Indocyanine green angiography of circumscribed choroidal hemangiomas

Objective To investigate the value of indocyanine green angiography(ICGA) in evaluating circumscribed choroidal hemangiomas. Methods Color photography,funds fluorescein angiography(FFA) and (ICGA) were performed in 10 caese (10 eyes) of circumscribed choroidal hemangiomas. Results Among 10 affected eyes examined in this series,the tumors were better defined in this series,the FFA in 8 of them.ICGA showed the tumors were composed of irregular choroidal vasculature in earlyphase (1-5 seconds) of ICGA and "washed out" phenomenon in late phase of ICGA in all of 10 affected eyes.An adjacent disturbances of choroidal circulation in a sector downstream from the tumors in 9 eyes. Conclusion ICGA is useful in diagnosis and differential diagnosis of circumscribed choroidal hemanfiomas and helpful in the laser photocagulation treatment of the tumor.(Chin J Ocul Fundus Dis,1998,14:81-83)
