Purpose: To describe a proportion of uveitis and to analyse differences between immune-related uveitis and infectious uveitis groups.
Methods: A retrospective study of 458 uveitis patients were categorized into immune-related uveitis, infectious uveitis, masquerade, and undetermined groups. The pattern of inflammation was described. Subgroup analysis was performed to compare pattern differences between immune-related uveitis and infectious uveitis groups.
Results: The most common location of inflammation was the anterior eye segment. Vogt-Koyanagi-Harada disease was the most common identifiable cause. From multivariate analysis, variables found to be significantly different between immune-related uveitis group and infectious uveitis group were age of onset, presence of systemic autoimmune diseases, HIV infection, and laterality.
Conclusions: Idiopathic anterior uveitis was the most prevalent diagnosis. Vogt-Koyanagi-Harada disease was the most common identifiable uveitis. Most immune-related uveitis patients were young and presented with chronic bilateral panuveitis, with most patients in the infectious uveitis group presenting with chronic unilateral posterior uveitis.
