Purpose:
This study aims to evaluate the ocular surface characteristics in children diagnosed with uveitis and explore the association between uveitis and dry eye disease (DED).
Methods:
We included 84 children, 42 with uveitis and 42 healthy children. We performed the OSDI questionnaire and several ocular surface tests, including osmolarity, NITBUT, Schirmer test, and vital staining. We used Fisher's exact test and Mann-Whitney to compare variables and a binomial logistic regression to determine the factors associated with DED.
Results:
The difference in the prevalence of DED between uveitis (54.8%) and healthy (31%) groups was statistically significant (p < 0.05). Most patients with uveitis had mixed DED, and none of the healthy subjects had a severe form of the disease. There were no statistically significant differences in most of the tear film tests. However, all parameters tended to worsen in the uveitis group, and lipid layer thickness was thinner (p < 0.036). The uveitis group exhibited significantly more symptoms (p < 0.05). In the multivariate logistic regression, uveitis was associated with an odds ratio (OR) of 3.0 (95% CI: 1.07-8.42, p < 0.05) for DED.
Conclusions:
Our findings demonstrate a significantly higher prevalence of DED in children with uveitis compared to their healthy counterparts. Furthermore, our analysis indicates that the risk of DED in pediatric patients with uveitis is threefold higher than in healthy children. Therefore, it is crucial for clinicians to vigilantly monitor the development of DED in pediatric patients with uveitis and consider the implementation of preventive treatments.
