Method of Literature Search
Articles were searched for in PubMed using different combinations of the following terms: orbit, eye, or ocular with Wegener's granulomatosis, Churg–Strauss, polyarteritis nodosa, systemis lupus erythematosis, atypical Cogan's, temporal arteritis, Kawasaki, dermatomyositis, rheumatoid arthritis, or Behcet's. A separate search was also performed for orbital vasculitis. The resultant articles were evaluated and those with information relevant to vascular inflammation within the orbit were included. Relevant articles listed in bibliographies of these articles were also included. In addition, other selected articles and books with information on the pathogenesis, epidemiology, diagnosis, and treatment of the systemic vasculitides were included.
