原田病的吲哚青绿血管造影特征

Indocyanine green angiographic findings in Harada＇s disease

目的 探讨原田 (Harada)病的吲哚青绿血管造影 (indocyanine green angiography,ICGA)特征。 方法 对 2 6例经荧光素眼底血管造影 (fundus fluorescien angiography,FFA)确诊的 Harada病患者2 6例 5 2只眼同时进行 ICGA检查。 结果 Harada病的主要 ICGA表现为 :1早期异常暗的背景荧光 5例8只眼 ;2脉络膜灌注不良 12例 18只眼 ;3脉络膜血管及涡静脉扩张 2 0例 34只眼 ;4晚期斑片状强荧光 8例 12只眼 ;5中周及后极部斑点状弱荧光 4例 5只眼。 结论 Harada病 ICGA特征 :早期异常暗的背景荧光 ,脉络膜灌注不良 ,脉络膜血管及涡静脉扩张 ,中周及后极部斑片状弱荧光 ,晚期可见斑片状强荧光。

Objective To study choroidal vascular abnormal characterisitics in Haradas disease using indocyanine green angiography (ICGA). Methods Twenty six cases(52 eyes)of Haradas disease were examined with fundus fluorescein angiography(FFA) and ICGA. Results ICGA findings in Haradas disease were as follows:(1)choroidal hypofluorescence with edema in the early phase;(2)choroidal filling defects;(3)dilatation of choroidal vessels and vortex veins;(4)choroidal hyperpermeability in late period;(5)multifocal lower fluorescence in the mid periphery and posterior pole of the fundus in the late phase. Conclusions ICGA can find lesions of the choroidal vessels i.e. hypofluorescence with edema,disturbances of choroidal circulation,dilatation of choroidal vessels and vortex veins and the lower fluorescence maculation in the early phase and choroidal hyperpermeability in the late phase.
