INDOCYANINE GREEN VIDEOANGIOGRAPHY OF HEMORRHAGIC RETINAL ARTERIAL MACROANEURYSMS

We examined 3 patients with isolated retinal macroaneurysms and second ary hemorrhage by standard fluorescein angiography (FA) and indocyanin e green (ICG) angiography. In contrast to standard FA, ICG videoangiog raphy clearly demonstrated the lesion to be pulsatile, contiguous with the arterial wall and pathognomonic of an isolated retinal artery mac roaneurysm ICG with its absorption and emission peak in the near-infra red range penetrates hemorrhage to a greater degree than does blue or green light of conventional FA. ICG can be essential in delineating th e specific cause of the bleeding and allow the physician to choose the correct specific form of treatment needed.
