Objective: To identify the clinical characteristics and prevalence of neoplastic and nonneoplastic inflammatory masquerade syndromes (IMSs) in a tertiary center and determine the useful diagnostic tests.
Methods: A retrospective cohort study of consecutive 1906 patients diagnosed with intraocular inflammatory disease.
Results: Of all patients initially diagnosed with intraocular inflammatory disease, we identified 116 (6%) patients with noninflammatory causes (neoplastic IMSs in 36/116; 31% and nonneoplastic IMSs in 52/116; 45%).
