Uveitic CME is a major cause of visual loss associated with uveitis. Systemic and/or local corticosteroid therapy and systemic immunosuppression with steroid-sparing agents such as cyclosporine, methotrexate, azathioprine, or others, effectively treats uveitis and associated CME in many patients. However, in many cases, CME persists in spite of adequate suppression of uveitis. No consensus exists on how best to treat such cases. The further addition of immunosuppressive agents appears to have little effect on this form of CME. Oral corticosteroids are useful, but high dosage and prolonged use can be associated with serious side-effects. Periocular and intravitreal corticosteroid injections are associated with well-known, significant side effects such as glaucoma and cataract formation. Vascular endothelial growth factor (VEGF) is suspected to play a role in the loss of vascular integrity in the eye and known to be induced by inflammatory cytokines, such as interleukin IL-1β and IL-6, which are elevated intraocularly in uveitis. In addition, it has been demonstrated that aqueous VEGF concentrations are statistically significantly higher in those uveitis patients with CME than those without CME. Inhibition of inappropriate VEGF activity is a potential approach to treatment of CME in uveitis given our current knowledge of the pathophysiology of this condition and also because of the clinical need for additional treatment options for these patients. Ranibizumab, a recombinant, humanized monoclonal antibody antigen-binding fragment (Fab) that neutralizes all active forms of VEGF-A, would target this pathway and may be useful in cases of persistent CME in uveitis patients. The objective of this study is to determine if an anti-VEGF agent, Lucentis, is safe and effective in leading to regression of macular edema due to chronic non-infectious uveitis in patients with well-controlled uveitis.
