FFA images of the right eye and left eye. a. The temporal field of the right eye showed a vascular loop. b. The posterior pole of the right eye was normal. c. The superior field of the left eye showed a descending venule that drained into the optic disc and divide into 2 branches when it reached the disc-like lesion. Approximately 5 small arterioles and 3 venules departed from the central cupping area. d. Hyperfluorescence with patchy fluorescence was evident in the inferotemporal field of the left eye. e. The temporal field of the left eye showed a vascular loop. f. The inferior disc-like lesions of the left eye showed marked hypofluorescence, and the area located between the optic disc and the lesion showed late hyperfluorescence
