Prevalence of Uveitis: An Epidemiological Analysis By Age, Sex, and Etiology

Uveitis represents a significant cause of visual impairment worldwide, accounting for up to 5–20% of blindness in developed countries. Its epidemiological patterns vary widely across geographic regions, age groups, sex, and underlying etiologies. This study provides an analytical overview of uveitis prevalence with a focus on demographic indicators—age and sex—as well as etiological classification. Available epidemiological studies indicate that uveitis most commonly affects individuals aged 20–50 years, with anterior uveitis remaining the predominant anatomical subtype. Sex distribution varies with etiology: autoimmune-related uveitis is more prevalent in females, whereas infectious uveitis is more common in males in several regions. Etiologically, non-infectious immune-mediated uveitis remains the leading cause globally, although infectious etiologies are more dominant in developing countries. Understanding these patterns is essential for improving diagnostic accuracy, guiding patient management, and designing region-specific public health strategies.
