Retinal changes and visual impairment.

摘要

He was undergoing hemodialysis for chronic kidney disease and had hypertension, dyslip-idemia, and peripheral vascular disease that led to amputation below his left knee. The patient's visual acuity was 20/50 in his right eye and 20/100 in his left. Scattered hemorrhages, cotton-wool spots, atherosclerosis of the retinal arterioles, and venous engorgement and beading were noted in his right retina (see accompanying figure). Although visualization of the left retina was obscured by posterior subcapsular cataract, hemorrhages and cotton-wool spots were discernible.
