[Acute loss of vision during therapy of chronic hepatitis C].

A patient undergoing combined therapy of chronic hepatitis C with pegylated interferon-α-2a (PEG-IFN-α-2a) and ribavirin suddenly developed severe loss of visual acuity. A central vein occlusion with macular edema was found and intravitreal injections of bevacizumab were initiated. Retinal occlusion is a known complication of therapy with pegylated interferon-α-2a and ribavirin. An interdisciplinary assessment of patients treated for a chronic hepatitis C as well as an early anti-VEGF administration can be helpful in the therapy of this complication of chronic hepatitis C.
