Metoprolol responding uveitis

Background. Noninfectious uveitis is usually managed by topical and systemic corticosteroids and in refractory cases by immunosuppressive drugs. Objective. To describe a patient with noninfectious anterior and posterior uveitis, refractory to corticosteroids, and immunosuppressive therapy, which responded to systemic metoprolol. Patient and methods. A 49-year-old patient was treated for 3 years with topical and systemic corticosteroids and systemic cyclosporin A for a bilateral anterior and posterior uveitis of unknown origin. The treatment did not result in resolution of the uveitis. A bilateral uveitic glaucoma developed and necessitated neodymium: YAG laser iridotomies and antiglaucoma medications. A systemic betablocker, metoprolol tartrate 50mg b.i.d., was administered for palpitations because of idiopatic paroxysmal supraventricular tachycardia and short ventricular tachycardia. Results. Following administration of metoprolol tartrate, the bilateral uveitis resolved. The corticosteroids and the cyclosporin A were withdrawn after 6 weeks without any recurrence. A trial to discontinue metoprolol after 6 months resulted in flare-up of the disease and only following its readministration the inflammation resolved. The patient is currently under metoprolol for a year without flare-ups. Conclusions. The use of metoprolol tartrate in this patient resulted in resolution of bilateral noninfectious uveitis. This is the first report of non-antiinfectious, antiinflammatory, or immunosuppressive drug effective for uveitis. It is possible that a subgroup of resistant uveitis may respond to drugs other than the traditional drugs, such as metoprolol, and that other forms of uveitis of unidentified origin exist.
