In vivo imaging of human retinal vascular wall fine structures in arterioles and venules using nonconfocal AOSLO. Structural images of a venule and b an arteriole of a 25-year-old male healthy control (RR0216). Arrows indicate individual vascular mural cells. c1 Structural image of a 40 µm arteriole located at 5° superior to the fovea in a 26-year-old female (RR0172). c2 Corresponding motion contrast perfusion map of c1. Periarteriolar capillary free zone along the arteriole is clearly visualized. d1, d2 Structural image and motion contrast perfusion map of a 50 µm venule located at 7° superior to the fovea in a 26-year-old male (RR0025). No distinct capillary free zone along the venule is observed
