Interpretation of ICG Angiography

我们描述了从实验工作中获得的基本结果，以及吲哚菁绿（ICG）荧光血管造影的解释标准。视网膜和脉络膜ICG定位的组织学证明。显示ICG可以通过绒毛膜毛细血管渗漏，但不能从视网膜血管和视网膜色素上皮（RPE）渗漏。ICG血管造影早期弥漫性薄纱样弱高荧光显示绒毛膜毛细血管内ICG充盈，晚期弥漫性高荧光显示ICG在脉络膜间质中弥漫性染色。早期ICG血管造影反映脉络膜循环，晚期反映RPE情况。脉络膜新生血管在ICG血管造影中表现良好，尤其是在血管造影中以暗边缘为特征。我们解释了早期和晚期的高荧光，以及ICG血管造影中的高荧光。ICG血管造影和荧光素血管造影是相辅相成的，两种血管造影一起解读有很大的价值。

We described fundamental results obtained from experimental works, and criterias for interpretation in indocyanine green (ICG) fluorescence angiography.Histological proof on localization of ICG in the retina and choroid. demonstrated that ICG can leak through the choriocapillaris, but not from the retinal vessels and retinal pigment epithelium (RPE). Diffuse veil-like weak hyperfluorescence in the early phase in ICG angiography revealed filling of ICG in the choriocapillaris, and diffuse hyperfluorescence in the late phase demonstrated tissue staining by diffusion of ICG in the choroidal stroma. ICG angiography in the early phase reflects choroidal circulation, and in the late phase does condition of RPE.Choroidal neovascularizations are well demonstrated in ICG angiography, particularly characterized with dark rim in angiography.We interpreted on hyperfluorescence in the early as well as late phase, and hyperfluorescence in ICG angiography. Both of ICG angiography and fluorescein angiography are mutually supplementary, and both angiographies show a great value to interprete together.
