Immunosuppressive drugs such as the therapeutic monoclonal antibody daclizumab, ciclosporin, methotrexate and Adalimumab, sold under the trade name Humira, have proven to be effective treatment options for birdshot chorioretinopathy. Substantial reduction and even stabilization of both vitreous inflammation and retinal vasculitis have been evident via electroretinography, during daclizumab (IL-2 receptor blocker) therapy. This is also supported by the observation of elevated levels of IL-2 in the eyes of patients.[1] Loss of visual acuity unrelated to the inflammation caused by the disorder, however, often remains unchanged despite usage of the drug.
