Relationship between foveal microstructures and visual outcomes in eyes with resolved central serous chorioretinopathy

Abstract

To determine whether significant correlations exist between the foveal microstructures and visual outcomes in eyes with resolved central serous chorioretinopathy (CSC). We retrospectively reviewed the medical records of patients who had a complete resolution of the serous retinal detachment (SRD) and had an intact ellipsoid zone in the fovea in the spectral-domain optical coherence tomographic (SD-OCT) images. Twenty-five eyes with CSC (CSC group) and 18 unaffected fellow eyes (control group) of 23 patients were evaluated. The eyes in the CSC group were divided into those with (n = 11) and those without (n = 14) visual disturbances after resolution of the SRD. The thickness of each retinal layer at the fovea was measured in the SD-OCT images. The photoreceptor outer segment (OS) length in the CSC group was significantly shorter than that in the control group (p = 0.0003). In addition, the photoreceptor OS length in the visual disturbances group was significantly shorter and the duration of SRD was significantly longer than that in the no visual disturbances group (p = 0.0230, p = 0.0021, respectively). The photoreceptor OS length is a good parameter to indicate the integrity of the foveal photoreceptors in eyes with a resolved CSC.
