Measurements of foveal and parafoveal vascular density in superficial and deep layers among NC, PC and GDM groups. The foveal vascular density in PC and GDM groups was lower than NC group both in superficial and deep layers (a, b). While the parafoveal vascular density in PC and GDM groups was lower than NC group in superficial layer (c), the measurement was higher than NC group in deep capillary layer (d). All the measurements were similar between PC and GDM groups (P > 0.05)
