Indocyanine green angiography in angioid streaks
1Department of Ophthalmology and Visual Sciences, Scientific Institute H S. Raffaele, University of Milano, Italy.
Purpose:
To define the indocyanine green angiographic aspects of angioid streaks, peau d'orange and choroidal new vessels.
Methods:
Fifty-seven consecutive patients (112 eyes) with angioid streaks were evaluated by fluorescein angiography and indocyanine green angiography.
Results:
Indocyanine green angiography showed angioid streaks in all eyes. We identified three different indocyanine green patterns of streaks (four groups): fluorescent (63%), hypofluorescent (8%), 'track-like' (19%) and mixed (10%). Angioid streaks were visualized better by indocyanine green angiography and red-free retinography than fluorescein angiography. Peau d'orange was seen better and found to be more widespread by indocyanine green angiography. Fluorescein angiography visualized choroidal neovascularization better, except for occult forms.
Conclusions:
Our findings show that angioid streaks have different indocyanine green angiography patterns. Considering that the hypofluorescent pattern was significantly observed in younger patients, indocyanine green angiography aspects might be correlated with different stages of the disease.
