Susac syndrome fundal pictures

(A) Optical coherence tomography infrared image of the right eye shows inferior retinal branch involvement (black arrows); the black arrows on the right of the image show occlusion, whereas on the left there is incomplete occlusion. (B) Fundus fluorescein angiography, late phase of the left eye in the same patient seen in A. There is arteriolar wall hyper-fluorescence seen along with frank leakage. (C) Late phase of fundus fluorescein angiography of the left eye demonstrates the requirement for peripheral views to gauge the extent of the retinal vascular involvement. (D) Late phase of fundus fluorescein angiography of the right eye shows superior arterial tree involvement in the same patient. (Source: Bose S, Papathanasiou A, Karkhanis S, et al.
