title: Wegener's granulomatosis: clinical manifestations, differential diagnosis, and management of ocular and systemic disease.
abstract: Wegener's granulomatosis (WG) is a systemic inflammatory disease whose histopathologic features often include necrosis, granuloma formation, and vasculitis of small-to-medium-sized vessels. WG involves many interrelated pathogenic pathways that are genetic, cell-mediated, neutrophil-mediated, humoral, and environmental. WG most commonly involves the upper respiratory tract, lungs, and kidneys, but has been reported to affect almost any organ. Ophthalmologic involvement is an important cause of morbidity in WG patients, occurring in approximately one-half of patients. The presence of unexplained orbital inflammatory disease, scleritis, peripheral ulcerative keratitis, cicatricial conjunctivitis, nasolacrimal duct stenosis, retinal vascular occlusion, or infrequently uveitis should raise the question of possible WG. A thorough clinical examination, laboratory testing, radiologic imaging, and histologic examination are essential to diagnosing WG and excluding potential mimics. Previously a uniformly fatal disease, treatment with cytotoxic and immunosuppressive agents has greatly improved survival. Treatment-related morbidity is a serious limitation of conventional therapies, leading to numerous ongoing studies of alternative agents.
