Pegylated Interferon-Associated Severe Retinopathy in a Patient with Chronic Hepatitis

ABSTRACT

This paper reports a case of pegylated interferon-associated retinopathy in a patient with chronic hepatitis C. A 32-year-old female with chronic hepatitis C undergoing pegylated interferon and ribavirin combination therapy complained of visual blurring. Features of interferon-associated retinopathy, including ocular complications such as cotton wool spots, retinal hemorrhages, macular edema, and branch retinal vein occlusion, were found in the fundus of both of her eyes. Pegylated interferon combination therapy was stopped, and the retinopathy of the patient was treated with intravitreal bevacizumab injections and panretinal photocoagulations. This case shows that pharmacokinetically improved pegylated interferon has ocular complications for patients with chronic hepatitis C. Accordingly, patients undergoing pegylated interferon treatment for hepatitis C need regular eye examinations for protection of their vision.
