Hyperfluorescence on fa

Web30 jan. 2015 · Fluorescein angiography (FA) of both eyes showed the presence of multiple discrete and partially confluent hyperfluorescent lesions due to window defects (Figure 2 ). In the right eye these lesions were multiple hyperfluorescent areas involving the macula in both early (2A) and late (2B) arteriovenous phase. WebThe hyperfluorescence and/or hypofluorescence seen both on FA and ICGA probably represent changes secondary to retinal inflammation. However, 76.8% of these hyperfluor-escent and hypofluorescent lesions seen on ICGA were not evident on FA, which suggests that these may reflect primary choroidal involvement as well as ICG leakage from choroidal
