New Treatment Options for Noninfectious Uveitis

Autoimmune uveitis is a group of sight-threatening inflammatory diseases associated with an exacerbated immunological response to ocular proteins. The Standardization of Uveitis Nomenclature Working Group Guidelines have recommended the use of corticosteroids as the first line of therapy for patients who present with active uveitis. However, long-term use of corticosteroids is associated with numerous adverse effects including cataract, glaucoma and metabolic disorders. In this context, new drugs developed to treat rheumatic diseases, and other autoimmune diseases, are being employed often as monotherapy or combined with other imnnunosuppressive drugs in order to decrease the corticosteroid burden on patients and to manage refractive uveitis. These drugs are currently being evaluated in the framework of uveitis and may open a new horizon with less side effects and more responsiveness for chronic cases. Among others, calcineurin inhibitor voclosporin, mammalian target of rapamycin inhibitor sirolimus, and the IL-1 trap rilonacept, are among these new agents and will be scrutinized in detail in this chapter. More efficient modes of drug delivery are also being employed to deliver high concentration of drug locally and to minimize systemic side effects. The new modes of drug delivery that we will describe in the index chapter include nanoparticles and iontophoresis. Copyright (C) 2012 S. Karger AG, Basel
