Choroidal neovascularization with interferon associated retinopathy: case report and review of literature.

We report a case of new interferon-associated ocular complication during treatment with combination of pegylated interferon plus ribavirin for chronic hepatitis C infection. Our patient developed choroidal neovascularization in addition to the classic interferon associated retinopathy. Choroidal neovascularization has not been reported before in association with interferon induced retinopathy. We describe our management to control the ocular symptoms and the retinal lesions with one year follow up. We also provide literature report on the natural history, the pathophysiology and the variable characteristics of interferon associated retinopathy versus hepatitis C related ophthalmopathy.
