All values are presented as mean ± SD or median (IQR). FAZ: foveal avascular zone; AI: acircularity index; FD-300-VD: vascular density within a 300 μm wide ring around the foveal avascular zone; SVC: superficial vascular complex; DVC: deep vascular complex; VD: vascular density; RT: retinal thickness; VA: visual acuity; MO: macular oedema; the minimal-VD quadrantal: quadrantal for short; SD: standard deviation; IQR: interquartile range.
