Figure 3

A representative optical coherence tomography angiography (OCTA) image of a 22-year-old healthy male subject in the signal strength 10 group. A vessel density (VD) map of the superficial capillary plexus (SCP) according to the Early Treatment of Diabetic Retinopathy Study (ETDRS) subfields. The VD for the total area was 17.8 mm−1 (A). A perfusion density (PD) map of the SCP according to the ETDRS subfields. The PD for the total area was 0.427 (B). The automatically detected foveal avascular zone (FAZ). The area, perimeter, and circularity were 0.28 mm2, 2.09, and 0.81, respectively (C).
