a Fundus examination revealed bilateral mild elevation and blurriness of the optic discs nasally. In the right eye, there was a small yellowish small focus consistent with retinitis adjacent to the fovea (circle). Similar findings were found in the left eye in the macular area (arrows). No retinal detachment or signs of inflammation in the periphery were observed. b Fluorescein angiography revealed bilateral mild disc hyperfluorescence without vascular leakage. An ICG scan of the right eye showed no focal lesions, while on the left, a few small hypofluorescent foci were observed within the macula and nasally to the disc (arrows). c OCT of the right eye (upper image) revealed hyperreflective retinal areas para-centrally, with irregularities in the photoreceptor layer (arrows). Additionally, small hyperreflective foci were observed in the posterior vitreous (circles), and the choroid was thickened. In the left eye, a similar pattern can be seen (white arrow) but without outer band irregularities
