X2 test or Fisher’s exact test was used for analysis of categorical variables. T-test was employed for analysis of continuous variables.
*P<0.05, **P<0.01, ***P<0.001.
†56 patients (62 eyes) have been detected to have thick choroidal.
CSCR, central serous chorioretinopathy; EDI-OCT, enhanced depth imaging-optical coherence tomography.
