Insights
Pediatric uveitis epidemiology is poorly understood, with anterior uveitis most common globally. Geographic variations exist, influenced by factors like juvenile idiopathic arthritis and infectious diseases, impacting uveitis patterns in children.
Area of Science:
- Ophthalmology
- Pediatrics
- Epidemiology
Background:
- Pediatric uveitis is rare, with limited epidemiological data, especially from developed nations.
- Tertiary referral center reports offer insights but face comparison challenges.
- Understanding uveitis patterns in children is crucial for diagnosis and treatment.
Purpose of the Study:
- To review the current understanding of pediatric uveitis epidemiology.
- To highlight global variations in uveitis types and associated conditions.
- To discuss diagnostic challenges and improvements in childhood uveitis.
Main Methods:
- Literature review of population-based studies and tertiary referral center reports.
- Analysis of uveitis patterns based on geographic region and age group.
- Examination of associations with systemic and infectious diseases.
Main Results:
- Anterior uveitis is the most common form worldwide, particularly in Western countries linked to juvenile idiopathic arthritis.
- Intermediate uveitis often lacks systemic associations.
- Posterior uveitis and panuveitis are more prevalent in low- and middle-income countries due to infectious etiologies and diseases like Behçet disease.
Conclusions:
- Significant geographic disparities exist in pediatric uveitis prevalence and types.
- Improved diagnostic methods have led to a decrease in idiopathic uveitis rates.
- Further population-based studies are needed to clarify pediatric uveitis epidemiology.
Abstract:
Uveitis is uncommon in children and its diagnosis and treatment are challenging. Little is known of the epidemiology of pediatric uveitis. Indeed, population-based studies in the literature are rare. However, there are many tertiary referral center reports that describe the patterns of uveitis in childhood, although few are from developed countries, and their comparison presents some issues. Anterior uveitis is the most frequent entity worldwide, especially in Western countries, where juvenile idiopathic arthritis is diffuse. Most cases of intermediate uveitis do not show any association with infectious or noninfectious systemic diseases. In low- and middle-income countries, posterior uveitis and panuveitis are prevalent due to the higher rates of infectious etiologies and systemic diseases such as Behçet disease and Vogt-Koyanagi-Harada disease. In recent decades, idiopathic uveitis rate has decreased thanks to diagnostic improvements.
