a Blood flow (microlitre per minute, µL/min) and (b) vascular pressure (millimeter of mercury, mm Hg) were simulated using Poiseuille flow, with inlet arterial pressure and outlet venous pressure fixed at 56.2 ± 14.0 and 20.0 ± 10.0 mmHg, respectively. c–e Simulated delivery of fluorescein at 17 s (arterial phase), 30 s (venous phase) and 600 s (recirculation), with clinical fluorescein images (registered to the same coordinate space) shown in (f–h) for comparison.
