[Interferon and retinal vasculitis]

The treatment of noninfectious posterior uveitis can lead to severe vision loss, and the first-line conventional treatment includes systemic steroids. When the prednisone doses necessary to control intraocular inflammation are above 0.3mg/day, a therapeutic association is proposed in order to lower the daily prednisone dose. The combined drugs are immunosuppressive or immunomodulative. The side effects of immunosuppressive drugs are oncogenic, infectious, and hematological, and can involve reproductive troubles, associated with specific toxic effects depending on the drug used. Recently adding polyclonal or monoclonal antibodies and the interferons to immunomodulative drugs has been suggested. Interferon alpha has been shown to be effective in Behçet's disease. The efficacy of interferon needs to be evaluated in other etiologies of retinal vasculitis through randomized studies.
