[Retinopathy caused by interferon. Apropos of a case]

Toxic retinopathy due to alpha interferon in a 20-year-old female is reported. This was an unusual case due to its severity in a non diabetic patient. Recovery of visual acuity was incomplete though angiographic tests normalized. Retinal toxicity in nondiabetic patients is usually reversible, suggesting careful surveillance of high risk patients with retinal microangiopathy given interferon therapy.
