In order to define the indocyanine green angiographic features of angioid streaks and associated posterior pole lesions and to compare them with fluorescein angiography, digital fluorescein and indocyanine green videoangiography was performed on 16 eyes of 8 patients with angioid streaks. Angioid streaks were visualized in all patients on fundus examination, fluorescein and ICG angiography. Streaks were hyperfluorescent in 15, hypo and hyperfluorescent in 1 of the 16 eyes with fluorescein angiography. ICG angiography showed hyperfluorescent streaks in 10 and hypofluorescent streaks in 6 eyes. Of the hyperfluorescent streaks, 6 had a hypofluorescent line between fluorescent edges and 4 were made up of numerous hyperfluorescent spots. Peau d'orange appearance was more evident in indocyanine green angiography as dark, round spots scattered in the temporal periphery. 12 of the 16 eyes had macular lesions. Of these, 5 had well-defined and 1 had occult choroidal neovascularization. Of the remaining 6 eyes, 3 had disciform scar, 1 had laser scar, 1 had toxoplasmic chorioretinitis scar and 1 had a streak involving the macula. As a conclusion, indocyanine green angiographic features of anioid streaks are different from fluorescein angiography. Angioid streaks and peau d'orange are more evident with ICG angiography.
