Typical FFA image of the MFC eyes. a The same eye in arterial stage. The active inflammatory lesion on the nasal side of the macula exhibits hyperfluorescence surrounding by a hypofluorescent boundary (white arrow). The inactive inflammatory lesion at the supraorbital vascular arch exhibits as a weakly fluorescent plaque (white arrow). b The same eye in venous stage. The active inflammatory lesions on the nasal side of the macula gradually increases, but the internal hemorrhage obscures the fluorescence (white arrow). The hypofluorescent rings around the inactive inflammatory lesion at the supraorbital vascular arch gradually strengthen in the FFA procedure (white arrow). c The same eye in advanced stage. The fluorescein leakage can be seen around the active inflammatory lesions on the nasal side of the macula with a blurred boundary. The fluorescence is obscured by the internal bleeding (white arrow). The inactive inflammatory lesion at the supraorbital vascular arch is homogeneously stained with optic disc leakage (white arrow). d The same eye in advanced stage. The atrophy lesions at the posterior pole and the optic disc are transflective. The CNV secondary inactive lesion at the macular area exhibits typical scar staining. e The healthy control
