Indocyanine green angiographic findings of chorioretinal folds

PURPOSE: To analyze indocyanine green (ICG) angiographic findings of chorioretinal folds. METHODS: Eight patients (9 eyes) in whom chorioretinal folds had been diagnosed were enrolled in this study. Color photography, fluorescein angiography (FA) and ICG angiography (IA) were performed. RESULTS: Indocyanine green angiography demonstrated choroidal venous congestion and a filling delay of the choroidal vessels in one case with an orbital tumor. In one posterior scleritis case, IA showed a filling delay of choroidal vessels in the early phase and multiple patchy hypofluorescent lesions scattered in the posterior pole during the late phase. Idiopathic cases showed choroidal venous dilatation. No abnormalities of the choroidal vasculature in the form of radial folds, were revealed in two cases of AMD. Linear hyperfluorescent areas suggestive of chorioretinal folds seen on IA were less numerous and wider than those observed on FA in some eyes. On the other hand, they were equally numerous and wider on IA than those on FA in other eyes. CONCLUSION: Indocyanine green angiography is useful for evaluating both pathological conditions of the choroidal vasculature and the width of chorioretinal folds at the level of the choroidal vasculature.
