A montage of a region of interconnected vessels in the parafoveal retina in one subject and the respective velocity plots of the average RBC’s over a three second video. Venules and arterioles were selected due to both the size of each vessel (< 50 µm) and whether a capillary region between both vessels are visualized for analysis. The video for each of the selected vessels were taken at different times and therefore the pulsatility will vary over time between each vessel. Scale bar is 50 µm.
