Do not discount the diagnosis of VKH based on race: self-reported race and ethnicity of patients with Vogt-Koyanagi-Harada disease in a predominantly white population.

BACKGROUND: We examined the racial and ethnic distribution of patients with Vogt-Koyanagi-Harada disease (VKH) in a Midwestern US population through a retrospective chart review of patients with VKH seen in a tertiary referral centre between 2012 and 2017. All patients were diagnosed by one uveitis specialist (DAG). We identified 32 patients with VKH seen during this time period. The mean age at diagnosis was 37.7 ± 15.7 years, 7 were male, 25 female. Mean follow-up was 36.7 ± 21.7 months. Nine patients reported themselves as White non-Hispanic, (28.1%), 9 as Black/African-American (28.1%), 2 as Asian (6.3%) and 9 as Hispanic or Latino (28.1%). Three patients (9.4%) were of Middle-Eastern origin. The 2010 census results for race and ethnicity in the state of Illinois were: 71.5% White, 14.5% Black/African-American, 4.6% Asian, and 6.7% as Some Other Race. From the total population 15.8% reported themselves as Hispanic or Latino (of any race). CONCLUSIONS: VKH was much more frequent among white non-Hispanic patients (28.1%) and Black/African-American patients (28.1%) in our patient population than in previous reports from the US (3-14% and 4-23% respectively). While Hispanic patients in this series were over represented in the VKH population compared with the overall census data, the percentage of VKH patients in this series who were White non-Hispanic and Hispanic was the same. The diagnosis of VKH should be considered in any patient with the appropriate clinical features, regardless of race or ethnicity.
