Choroidal change in acute anterior uveitis associated with human leukocyte antigen-B27

PurposeTo evaluate choroidal changes in eyes with acute anterior uveitis associated with human leukocyte antigen (HLA)-B27MethodsIn 44 patients with first-onset, unilateral, acute-onset (ResultsCompared to the fellow eyes, eyes with acute anterior uveitis showed significant choroidal thickening on the subfoveal and parafoveal areas at baseline (all P ConclusionsEyes with HLA-B27-associated anterior uveitis showed significant choroidal thickening at acute phase that subsequently decreased after treatment, indicating subclinical choroidal inflammation in the eyes. Choroidal thickness might indicate disease activity in acute anterior uveitis associated with HLA-B27.
