SD: standard deviation; RT: retinal thickness; RV: retinal volume; SVD: superficial vessel density; DVD: deep vessel densities; FAZ: foveal avascular zone. One-way ANOVA for normal distribution data among the 3 groups followed by post hoc least significant difference analysis between each two groups. a: compared with control; b: compared with NPDR/DME- group, was deemed to be statistically significant.
