Fundus examination of the right eye showed crescent-shaped retinal ischemic whitening involving the superior and inferior fovea with multiple retinal arterial wall plaques called as Gass plaques (black arrows). Fundus fluorescein angiography revealed the patched arterial wall hyper-fluorescence of Gass plaques in addition to obstruction of midarteriolar segment located at the superior of fovea. Vertical spectral-domain optical coherence scan of the retinal ischemic areas demonstrated hyper-reflectivity of inner retinal layers with posterior shadowing. In light of these multimodal imaging findings, the preliminary diagnosis was probable Susac syndrome and therefore, further medical examination was carried out by the Otorhinolaryngology and Neurology departments. While audiometry was normal; MRI imaging was reported as white matter disturbances affecting peri-corpus callosum compatible with Susac syndrome.
