Abstract
A 43-year-old man presented with sudden painless loss of vision in his left eye. Funduscopic examination revealed hyperemia and swelling of the optic nerve, macular edema, diffuse intraretinal hemorrhages, and dilated and tortuous retinal veins.
A 43-year-old man with hypertension presented with sudden painless loss of vision in his left eye. Visual acuity was measurable only by ability to count fingers at a distance of 3 feet. A relative afferent pupillary defect was also noted. Intraocular pressure was at the upper limit of the normal range, at 20 mm Hg bilaterally. Funduscopic examination was remarkable for optic-nerve cupping of the right eye (Panel A, arrow) and hyperemia and swelling of the optic nerve (Panel B, arrow), macular edema, diffuse intraretinal hemorrhages, and dilated and tortuous retinal veins (Panel B, arrowhead) in the left eye.
