case_images: Fundus photography of the right eye (a) and left eye (b). There are multiple cotton-wool spots and significant arterial narrowing with posterior pole edema in the left eye. The right eye is normal.

case_images: Fundus exam of the right eye was normal, but in the left eye, we noticed cotton-wool-like geographic white patches in posterior pole and equatorial area of the retina (Fig. 1).
case_images: Fluorescein angiography and optical coherent tomography of the left eye. There is choroidal and arterial filling delay in the arterial and venous (a, b) and late (c, d) phases of FAG. Some arteries are not filled to the end of FAG. OCT of the left eye (f) shows hyperreflecting thickened inner retinal layer due to ischemic edema, and the right eye (e) is normal.

case_images: In fluorescein angiography, delayed retinal arterial filling (after 40 s) and vascular filling defect in the regions of white patches were obvious (Fig. 2a-d). Optical coherence tomography demonstrated increased reflectivity and thickness of the retinal inner layers of the left eye (Fig. 2e, f).
