Comparisons of the retinal capillary density (RCD) in diabetic patients with controls on OCT-A images in the superficial and deep retinal capillary layers (SRCL and DRCL). The RCDs in the SRCL (a) and DRCL (b) of both the no DR (NDR) group and the mild DR (MDR) group were lower than those of the control group. In addition, the RCDs in the MDR group were also decreased compared to those of the NDR group. *P < 0.05, **P < 0.01, ***P < 0.001
