Correlations between Log V-FABP4 or Log V-VEGFA and ocular blood flow (MV-MT at baseline). Levels of Log V-FABP4 or Log V-VEGFA were plotted against MV-MT at the baseline for each subject (n = 40, panel A; Log V-FABP4; r = − 0.62, P < 0.001, panel B; Log V-VEGFA; r = − 0.48, P = 0.005). Open circles, subjects with non-PDR; closed circles, subjects with PDR; FABP4 fatty acid-binding protein 4; VEGFA vascular endothelial growth factor A; V-FABP4 vitreous FABP4; V-VEGFA vitreous VEGFA, MBR mean blur rate; ONH optic nerve head; MV the MBR of the vascular area of the ONH, MT the MBR of the tissue area of the ONH.
