(A) Brain DWI. The brain DWI scan showed the brain was scattered with ischemic foc (arrows). (B) Fundus photography of the right eye showing tortuosity and dilatation of all branches of the central retinal vein, cotton wool patches, blot and flame-shaped hemorrhages throughout all four quadrants, without optic disc edema. (C) Optical Coherence Tomography (OCT) of the macula was within normal limits.

Based on head magnetic resonance imaging (MRI) and diffusion weighted imaging (DWI) (Figure 2A), cerebral infarction were diagnosed. The right eye exhibited tortuosity and central retinal vein dilatation, cotton wool patches, blot and flame-shaped hemorrhages throughout all four quadrants, without optic disc edema, as evidenced by fundoscopy (Figure 2B). The macula Optical Coherence Tomography (OCT) was normal ((Figure 2C).
(A) Fluorescein angiography of the right eye in 31 s showing marked delay in venous filling, masking by retinal hemorrhages. (B) Fluorescein angiography of the right eye showing staining of dilated tortuous veins, stiff and thin arteries, and masking by retinal hemorrhages. (C) Fluorescein angiography of the right eye after 3 months showing microangioma and retinal no perfusion areas.

Fundus fluorescein angiography (FFA) revealed significant arteriovenous transit delay, dilated tortuous vein staining and retinal hemorrhages-related masking (Figures 3A, B). FFA revealed there was non-perfusion zone in the retinal (Figure 3C).
