Fig. 4 — Relations of blood flow velocities (BFVs) between OD and OS in healthy controls (HCs). Both BFVs in arterioles and venules were measured in OD and OS of the HC cohort (N = 20, 40 eyes). Strong inter-eyes correlations in BFVs were found in the arterioles (top panel, r = 0.84, P < 0.001) and venules (bottom panel, r = 0.87, P < 0.001)
