INDOCYANINE GREEN VIDEOANGIOGRAPHY OF ANGIOID STREAKS

Purpose: This study was performed to define the indocyanine green angi ographic features of angioid streaks and associated posterior pole les ions and to compare them with fluorescein angiography, Methods: Digita l fluorescein and indocyanine green videoangiography was performed on 16 eyes of 8 patients with angioid streaks. Results: Streaks were hype rfluorescent in 15, hypo- and hyperfluorescent in 1 of the 16 eyes wit h fluorescein angiography, Indocyanine green angiography showed hyperf luorescent streaks in 10 and hypofluorescent streaks in 6 eyes, Of the hyperfluorescent streaks, 6 had a hypofluorescent line between fluore scent edges and 3 were made up of numerous hyperfluorescent spots, Pea u d'orange appearance was more evident in indocyanine green angiograph y as dark, round spots throughout the posterior pole, Fluorescein angi ography confirmed the presence of well-defined choroidal neovasculariz ation in 5 eyes. In one eye, occult choroidal neovascularization which was not evident on fluorescein angiography, became well-demarcated on indocyanine green angiography. Conclusion: Indocyanine green angiogra phic features of angioid streaks are different from fluorescein angiog raphy. Angioid streaks and peau d'orange are more evident with indocya nine green angiography.
