The PD, VLD, and FD are expressed as the mean (standard deviation) for the SRL, DRL, and Non-seg layers.
DR, diabetic retinopathy; DRL, deep retinal layer; FD, fractal dimension; Non-seg, non-segmented layer; NPDR, non-proliferative diabetic retinopathy; PD, perfusion density; PDR, proliferative diabetic retinopathy; SRL, superficial retinal layer; VLD, vessel length density.
