{Abstract}: <B>BACKGROUND: </B>The aim of this study was to determine whether anterior scleral thickness (AST) varies significantly between patients with central serous chorioretinopathy (CSCR) versus normal individuals. To validate scleral thickness measurements by ultrasound biomicroscopy (UBM) vis a vis anterior segment optical coherence tomography (ASOCT).<BR><B>METHODS: </B>This case-control study analyzed 50 eyes of 50 patients with CSCR (cases) and compared it with that of 50 eyes of 50 age- and gender-matched controls. In cases, AST was measured at 1 mm and 2 mm temporal to the temporal scleral spur by ASOCT and UBM. In controls, AST was measured only by ASOCT. In all participants, posterior choroidal thickness (CT) was measured subfoveally, 1 mm nasal and 1 mm temporal to fovea by enhanced depth imaging optical coherence tomography.<BR><B>RESULTS: </B>The mean AST, as measured by ASOCT among cases and controls was 703.86 μm and 667.54 μm, respectively (P = 0.006). The mean AST by ASOCT and UBM in cases were 703.86 μm and 657.42 μm, respectively (P = 0.001). AST measurement by ASOCT and UBM showed a positive and statistically significant correlation (r = 0.431, P = 0.000). The mean CT among cases and controls was 443.56 μm and 373.88 μm, respectively (P = 0.000). We found a weak positive correlation (r = 0.11) in cases and weaker positive correlation in controls, between CT and AST measured by ASOCT.<BR><B>CONCLUSIONS: </B>Our findings suggest that AST varies significantly between patients with CSCR versus normal individuals. We found poor agreement of AST when measured by ASOCT and UBM.
