Central Retinal Artery Embolus

CL is a 70-year-old man who presented with the history of marked reduction of vision in his left eye several days ago. Examination found vision 20/30 OD and OS of hand motions at 1 meter. He had a 3+ afferent papillary defect in this eye. Slit-lamp examination was normal and fundus examination found some narrowing of the retinal arterioles and a faint reddish appearance to the central macula. It was assumed that a vascular event had occurred and a workup was done including erythrocyte sedimentation rate, C-reactive protein, complete blood count (CBC) with platelet level, antiphospholipid antibodies, plasma homocysteine, and a carotid duplex scan. These tests were unremarkable except for 50% stenosis of both carotid arteries.
