Correlation between baseline retinal microstructures in spectral-domain optic coherence tomography and need for early intervention in central serous chorioretinopathy

PURPOSE: To investigate the association between baseline retinal microstructures observed with spectral-domain optical coherence tomography (OCT) and the need for early intervention in central serous chorioretinopathy (CSC). METHODS: Cases of acute CSC from July 2011 to December 2014 were retrospectively reviewed. OCT images were further classified using six parameters: foveal serous retinal detachment; pigment epithelial detachment; fibrinous exudates in the subretinal space; retinal pigment epithelium bumps; thickened outer retinal layer and hyper-reflective dots in the intraretinal and/or subretinal layer. Correlation among these parameters and the need for intervention was analysed. Receiver operating characteristic (ROC) curves were performed to identify the optimal number of parameters for prediction. RESULTS: A total of 47 eyes from 47 patients were included. Among these, 25 eyes required treatment. The presence of subretinal hyper-reflective dots was the only OCT factor having significant association with the need for intervention. An ROC curve analysis revealed that the optimal cut-off value (Youden index) was achieved when combining subretinal hyper-reflective dots with aged ≥50 years and female sex for analysis (area under the curve, 0.735; Youden index: 0.425). CONCLUSION: The presence of subretinal/intraretinal hyper-reflective dots observed with OCT, female and aged ≥50 years might help predict the need for early intervention in acute CSC.
