Quantitative transit time metrics for individual microvascular layers show similar trends across animals. Kinetic measurements include arrival time (A), peak time (B), time to peak (C), and mean transit time (MTT), where MTT can be calculated from the arteriovenous transport function between artery-vein pairs in the inner retina and choroid (D), from a model-based residue deconvolution approach (E), or from a singular value decomposition (SVD) residue deconvolution solution (F). Measurements from individual animals are shown as blue lines with differently oriented triangles for each animal. Mean values are shown as red squares. Unfilled symbols represent measurements based on a retinal artery time reference (A-C, Section 2.6.5) or calibration (D-F, Section 2.5.3) while filled symbols used a choroidal artery time reference or calibration. IR – Total Inner Retina, ONF/GCL – Optic Nerve Fiber/Ganglion Cell Layer, IPL – Inner Plexiform Layer, OPL – Outer Plexiform Layer, and CC – Choriocapillaris.
