Abstract
BACKGROUND
Currently, there are a limited number of reports of structural changes in the retina and choroid in acute anterior uveitis (AAU). The aim of this study was to evaluate choroidal and central foveal thicknesses during episodes of AAU.

METHODS
The medical records of 120 patients with AAU and 120 healthy subjects matched for age, sex, and spherical equivalent of refractive error were reviewed. Subjects were divided into group 1 (AAU-affected eyes), 2 (unaffected fellow eyes), and 3 (healthy control eyes).

RESULTS
In the uveitis group, etiologic diagnoses included human leukocyte antigen (HLA)-B27-associated (n = 71) and idiopathic (n = 49) AAU. The mean subfoveal choroidal thicknesses (SFCTs) in groups 1-3 were 326.7 ± 64.2, 296.1 ± 66.6, and 294.9 ± 41.7 μm, respectively. The corresponding mean central foveal thicknesses (CFTs) were 273.5 ± 29.3, 264.4 ± 24.6, and 263.0 ± 30.8 μm, respectively. The AAU group exhibited a significantly greater SFCT than the control groups (P < .001). Relative to the control group, while eyes with idiopathic AAU exhibited a significantly greater CFT, those with HLA-B27-associated AAU exhibited no such significant difference. Anterior chamber cell grade was not associated with SFCT or CFT. CONCLUSIONS
The SFCT increased significantly during AAU. This indicates the importance of OCT examination for detection of subclinical choroidal and retinal changes in all types of AAU.
