A 60-year-old man with diabetes mellitus had a sudden decrease in vision in his right eye 3 weeks after confirmed West Nile virus infection. Visual acuity in the right eye was 20/400. Fundus examination showed bilateral multifocal chorioretinitis, which was associated with proliferative diabetic retinopathy in the right eye and severe nonproliferative diabetic retinopathy in the left eye. There were deep, dense retinal hemorrhages, retinal opacification, and retinal arterial sheathing in the macula of the right eye. Fluorescein angiography revealed extensive capillary nonperfusion in the macular area of the right eye. Six months later, vision remained unchanged and a choroidal neovascularization developed over a chorioretinal scar in the same eye.
