Uveitis is an inflammatory disorder of the uveal tract of the eye that can affect both adults and children. Non-infectious uveitis can be an expression of a systemic autoimmune condition, or it can be idiopathic. It is a serious disease, associated with possible severe complications leading to visual impairment and blindness. For this reason, a prompt diagnosis and assessment of an appropriate treatment, with the collaboration of specialists such as ophthalmologists and rheumatologists, are extremely important. Many treatment options may be associated to side effects; therefore, clinicians should follow a stepladder approach starting with the least aggressive treatments to induce remission of inflammation. In this review, we reported the current evidence-based treatments for non-infectious uveitis in pediatric and adult patients with particular attention to the biologic response modifier treatment options. Important multicenter studies have demonstrated the efficacy of adalimumab, both in adults (VISUAL I, VISUAL II, VISUAL III) and in children (SYCAMORE, ADJUVITE), while for other agents data are still scarce.

There is accumulating evidence that tumor necrosis factor plays a major role in the pathogenesis of rheumatoid arthritis. Recent biotechnological advances have allowed for the development of agents that directly target TNF, a pro-inflammatory cytokine. In the last 2 years, the U.S. Food and Drug Administration and the European Union’s Commission of the European Communities have approved two biological agents for the treatment of refractory RA, etanercept and infliximab. Etanercept is a fusion protein, composed of the Fc portion of immunoglobulin G1 and the extracellular domain of a TNF receptor (p75). Infliximab is a chimeric monoclonal antibody composed of murine variable and human constant regions. In placebo-controlled trials, both agents have proven to be effective and well tolerated in PA patients.
