Indocyanine green videoangiography of angioid streaks.

PURPOSE

This study was performed to define the indocyanine green angiographic features of angioid streaks and associated posterior pole lesions and to compare them with fluorescein angiography.

METHODS

Digital fluorescein and indocyanine green videoangiography was performed on 16 eyes of 8 patients with angioid streaks.

RESULTS

Streaks were hyperfluorescent in 15, hypo- and hyperfluorescent in 1 of the 16 eyes with fluorescein angiography. Indocyanine green 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 throughout the posterior pole. Fluorescein angiography confirmed the presence of well-defined choroidal neovascularization 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 angiographic features of angioid streaks are different from fluorescein angiography. Angioid streaks and peau d'orange are more evident with indocyanine green angiography.
