PurposeTo identify the demographic and clinical characteristics, along with the frequency, of neoplastic masquerade syndromes in a tertiary uveitis clinic.DesignA retrospective observational cohort.MethodsDemographic and clinical data on all patients presenting to the National Eye Institute (NEI) with uveitis between 2004 and 2012 were used to compare neoplastic masquerade syndromes and uveitis.ResultsA total of 853 patients presenting with uveitis were identified. Of these, 21 (2.5%) were diagnosed with neoplastic masquerade syndromes. The average age at presentation of masquerade syndrome patients was 57 years (median, 55; range, 38-78); for uveitis, 42 years (median, 43; range, 3-98) (P = 0.0003). There were 48% females in the masquerade syndromes group, compared with 59% females in the uveitis group. African American patients represented 9% of the masquerade syndrome patients and 36% of uveitis patients (P = 0.01). Mean worse eye visual acuity was 0.89 (20/160) in neoplastic masquerade syndromes, and 0.66 (20/100) in the uveitis group (P = 0.21). Of masquerade syndrome patients, 90% had posterior inflammation, compared with 63% of uveitis patients (P = 0.006). Of those with masquerade syndromes, 48% of patients had unilateral disease, compared with 27% of the uveitis patients (P = 0.04).ConclusionsPatients with neoplastic masquerade syndromes were more likely to be older, male, or non-African American and to have posterior segment inflammation and unilateral disease. Patients with masquerade syndromes also had worse visual acuity than did uveitis patients. These differences in clinical characteristics may help to raise the suspicion for neoplastic masquerade syndromes.Published by Elsevier Inc.
