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.
