Longitudinal follow-up measurement of the velocity changes in the RBC flow in the same mouse for 14 weeks. (a, b) The RBC flow velocity in the retinal vessels of the artery, vein, and capillary measured at different ages in the same mice (n = 2) with the two strains, (a) C57BL/6 and (b) Balb/c. For comparison, the cross-sectional measurement results presented in Figure 4 are shown by the gray lines with symbols. The symbols and shades represent the mean value and standard deviation, respectively.
