Faf hypofluorescence
WebDec 20, 2024 · In active lesions occurring at the margins of an atrophic lesion, FA typically shows early hypofluorescence with late leakage. As in other inflammatory choroidopathies, ICG is characterized by hypofluorescent areas from early to late frames. FAF has become increasingly useful and a minimally invasive tool for monitoring disease progression in SC. WebFA revealed hypofluorescence or blockage corresponding to areas of the lesions in the early phase, followed by hyperfluorescence in the late phase consistent with staining ( Fig. 3A; see also Web Extra Fig. 4 ). …
