Multimodal imaging of the left eye at first presentation. a Fundus photograph showing a localized inflammatory vitreous exudate overlying an infiltrated optic disc and peripapillary retina with associated retinal hemorrhages b Late-phase fluorescein angiography demonstrating optic disc leakage and masking effect from retinal hemorrhages. c SS OCT of the optic nerve head showing a “mushroom-shaped” hyperreflectivity of the prepapillary vitreous exudation seen on clinical examination. d Macular SS OCT showing an associated shallow macular serous retinal detachment. e, f, g SS OCTA revealing a dark area overlying the optic disc due to blockage from the prepapillary exudate. The prepapillary hypointense area decreases in size while scanning deeper layers, reflecting the “mushroom-saphed” pattern of the prepapillary vitreous exudate. Note the presence of a superotemporal hyposignal area (arrows). One month after presentation, SS OCT shows the resolution of the prepapillary vitreous exudate and serous retinal detachment (h, i)
