    PURPOSE: The sclera is reportedly thicker in eyes with central serous chorioretinopathy (CSC) than in healthy control eyes. We compared the scleral thicknesses of the affected and unaffected fellow eyes of patients with unilateral CSC. METHODS: We retrospectively examined the findings of 115 patients with unilateral CSC. Comparisons of the spherical equivalent (SE), axial length, anterior chamber depth (ACD), subfoveal choroidal thickness (SCT), scleral thickness, and presence of peripheral ciliochoroidal effusion (CE) of the affected and fellow eyes were made. Using anterior segment optical coherence tomography, scleral thickness was measured vertically, 6 mm posterior to the scleral spur in the superior, temporal, inferior, and nasal directions. RESULTS: No significant differences in scleral thickness in all four directions, SE, axial length, ACD, and frequency of CE were found between the affected and unaffected fellow eyes. The only significant difference between the affected and fellow eyes was observed in the SCT (398.8 µm vs. 346.6 µm, P < 0.001). CONCLUSION: A thickened choroid seems to have a direct effect on CSC development. In contrast, the affected and fellow eyes showed no significant difference in scleral thickness, indicating that scleral thickening may be a predisposing factor for the development of CSC.

     View Summary

    PURPOSE: Central serous chorioretinopathy (CSC) is a retinal disorder characterized by serous retinal detachment with or without pigment epithelial detachment in the posterior pole of the eye. We aimed to elucidate the relationship between scleral thickness and choroidal structure in CSC eyes. METHODS: This single-center retrospective study included 111 eyes of 111 CSC patients. Using swept-source optical coherence tomography, the horizontal cross-sectional images of the posterior choroid were converted to binary images by semiautomated software. The luminal and stromal areas of the choroid were measured, and the luminal/stromal (L/S) ratios of the whole choroid (WC), inner choroid, and outer choroid (OC) at 1500 µm, 3000 µm, and 7500 µm ranges centered on the fovea were calculated. Correlations of L/S ratio and age, spherical equivalent, axial length, subfoveal choroidal thickness (SCT), and scleral thickness were determined. Scleral thickness was measured vertically, 6 mm posterior to the scleral spur in four directions. RESULTS: SCT and mean scleral thickness were significantly positively correlated with the L/S ratio in all ranges of WC and OC. Multiple regression analysis found that SCT and mean scleral thickness were significantly correlated with the L/S ratio, and the strength of correlation of mean scleral thickness (WC: 0.386, P < 0.001; OC: 0.391, P < 0.001) was greater than that of SCT (WC: 0.368, P < 0.001; OC: 0.383, P < 0.001) in 7500 µm range. CONCLUSIONS: Thick sclera appeared to play a role in an increase in the luminal component of the posterior choroid in CSC eyes.
