Analysis of the pulse waveform at the optic nerve head (ONH) using laser speckle flowgraphy (LSFG). Representative color-coded composite map (a). The ONH, the mean blur rate (MBR), and other waveform parameters can be measured within the marked circle. Pulse waves showing MBR changes due to the cardiac cycle for 4 s. The total number of frames is 118 in 1 scan (b). The change of the MBR in one heartbeat (c)
