A sudden loss of vision attributable to Purtscher-like retinopathy occurred in a 4-year-old boy with focal segmental glomerulosclerosis and nephrotic syndrome as well as mild chronic renal failure. This retinopathy was bilateral. After treatment with intravenous methylprednisolone, infusion of 20% albumin, and low molecular weight heparin (nadroparin calcium), his visual acuity improved within 3 days. Ischemic retinal blanching and hemorrhages gradually disappeared. The pathogenesis of this disorder is unknown.
