Parafoveal and peripapillary superficial vessel density and parafoveal superficial retinal thickness were the main parameters of interest. Area under receiver operating characteristic curves were calculated.Results: There were significant decreases in parafoveal superficial vessel density in primary open-angle (40.06±4.54%, P |
