title: [Interferon dysoric retinopathy in chronic viral hepatitis C: case report and literature review].
abstract: BACKGROUND
  The ophthalmic complications following interferon therapy in chronic hepatitis C are rare. The most common adverse ophthalmic outcome is the dysoric retinopathy characterized by the presence at the fundus examination of cotton wool spots and retinal hemorrhages particularly around the optic disc.
  
  
  METHODS
  A 63-year-old man presented to the hepatology department with a compensated cirrhosis C. His medical history was positive for hypertension controlled by medical treatment. A combined treatment with pegylated interferon α2a plus ribavirin was initiated. Three months later, the patient reported a sudden decreased vision in both eyes. Fundus examination revealed cotton wool spots with retinal hemorrhage. The diagnosis of dysoric retinopathy was established. The antiviral treatment was discontinued. One month later, the patient was asymptomatic and the ocular lesions have disappeared.
  
  
  CONCLUSIONS
  Dysoric retinopathy is a non-specific complication of interferon therapy in chronic hepatitis C. Despite its good prognosis, a careful fundus examination is required before and during the treatment especially for the patients with risk factors for this adverse event (advanced age, diabetes and high blood pressure).
