Purpose: The aim of our study was to investigate the change in the subfoveal choroidal thickness in unilateral acute anterior uveitis with treatment. Choroidal inflammation is uncommon but can occur in the acute stage of anterior uveitis. Methods: All diagnosed patients with the first episode of unilateral acute anterior uveitis were included in the study conducted for a period of July 2017–July 2018. Choroidal thickness at subfoveal region was measured with spectralis spectral domain optical coherence tomography using enhanced depth-imaging scans. Standardized, masked manual measurement of the choroidal thickness was performed in the center of the ETDRS fields. The unaffected fellow eye of the same patient was taken as a control group and their subfoveal choroidal thickness was measured. Follow up of the patients was done at 2 weeks posttreatment to reevaluate the choroidal thickness. Results: A total of 61 eyes of 61 patients with unilateral acute anterior uveitis were included in the study. The mean central subfoveal choroidal thickness was significantly higher (304.82 ± 73.17 μm) as compared to that of controls (251.28 ± 66.38 μm) at presentation (P < 0.001). Following treatment and at two weeks follow up, the subfoveal choroidal thickness significantly reduced from 304.82 ± 73.17 to 274.46 ± 63.82 μm (P < 0.001). Also the subfoveal choroidal thickness was positively correlated with visual acuity (r = 0.22, P < 0.251) before treatment. Conclusion: Acute anterior uveitis is associated with an increase in the subfoveal choroidal thickness followed by the significant decrease in choroidal thickness with treatment, suggesting that choroid is also inflamed along with anterior segment inflammation.
