Peripheral ulcerative keratitis as presenting manifestation of systemic microscopic polyangiitis: a case report.

Abstract

Microscopic polyangiitis is a rare autoimmune disease of unknown etiology, characterized by inflammation and necrosis of blood vessels. It forms a part of the antineutrophil cytoplasmic antibody-associated vasculitides-a heterogeneous group of disorders characterized by vasculitis. It is a systemic disease affecting multiple organs. The patients may present with a wide variety of symptoms. Ocular manifestations may present as its initial clinical symptoms, necessitating a multidisciplinary approach for reducing the morbidity and mortality. Early diagnosis aids in the formulation of appropriate treatment and prevention of further complications. Aggressive treatment, including surgery, is often necessary to limit structural damage and preserve visual function. We present the case of an 82-year-old woman who initially presented with peripheral ulcerative keratitis that led to the diagnosis of microscopic polyangiitis.
