title: Indocyanine green videoangiography of hemorrhagic retinal arterial macroaneurysms.
abstract: We examined 3 patients with isolated retinal macroaneurysms and secondary hemorrhage by standard fluorescein angiography (FA) and indocyanine green (ICG) angiography. In contrast to standard FA, ICG videoangiography clearly demonstrated the lesion to be pulsatile, contiguous with the arterial wall and pathognomonic of an isolated retinal artery macroaneurysm. ICG with its absorption and emission peak in the near-infrared range penetrates hemorrhage to a greater degree than does blue or green light of conventional FA. ICG can be essential in delineating the specific cause of the bleeding and allow the physician to choose the correct specific form of treatment needed.
