Processed OCTA images in MATLAB showing larger periarteriole (111 µm; vessel linear distance = 4.2 mm) and perivenule CFZ (93.2 µm; vessel linear distance = 6.7 mm) in a 66-year-old high-risk cognitively unimpaired (CU) female (b) than those observed in a 68-year-old low-risk CU female (a; periarteriole CFZ = 72.6 µm, vessel linear distance = 4.7 mm; perivenule CFZ = 64.9 µm, vessel linear distance = 5 mm). Periarteriole CFZ; red “A” and arrows. Perivenule CFZ; blue “V” and arrows. Scale bar: 200 µm
