Trends in Patterns of Posterior Uveitis and Panuveitis in a Tertiary Institution in Singapore

Abstract

The study aims to analyze the trends of posterior uveitis and panuveitis patients seen by a tertiary eye center in Singapore between 2004 and 2012. We conducted a retrospective analysis of 363 consecutive new cases of posterior uveitis and panuveitis. The cases were segregated into idiopathic, infectious, or noninfectious. We found statistically significant differences between etiologies and ethnicity (p = 0.014). We noticed a statistically significant downward trend (Spearman's rho (ρ) = -0.812, p = 0.008) for dengue uveitis, and an upward trend for the idiopathic category (Spearman's rho (ρ) = 0.753, p = 0.019). We observed differences between etiologies and ethnicity, pointing toward potential susceptibility variations. There was an upward trend of idiopathic causes, possibly due to better control of systemic and infectious etiologies. The dengue uveitis incidence correlates well with our national statistics. The downward trend of dengue uveitis could be due to the introduction of Singapore's dengue surveillance in 2005, emphasizing the importance of controlling the disease.
