Patterns and Etiologies of Uveitis at a Tertiary Referral Center in Taiwan

Purpose: To analyze the patterns and etiologies of uveitis at a tertiary referral center in Taiwan.Methods: This retrospective chart review of uveitis patients from January 2001 to December 2014 updates a previous study a decade ago (2003).Results: We identified 450 patients, among whom anterior uveitis was most common, followed by panuveitis, posterior uveitis, and intermediate uveitis. A specific diagnosis was identified in 331 patients. In 73 infectious uveitis cases, herpetic anterior uveitis was the leading cause, followed by endogenous bacterial endophthalmitis and acute retinal necrosis. In 258 non-infectious uveitis cases, HLA-B27-associated uveitis was most commonly seen, followed by Vogt-Koyanagi-Harada disease and Posner-Schlossman syndrome. Compared with our previous study, we found more viral infection and sarcoidosis but fewer cases of Behcet disease, tuberculosis, and toxoplasmosis.Conclusions: Our results provide useful information about the patterns and etiologies of uveitis in a selected population in Taiwan.
