Another one just appeared. One of the first non-invasive methods for assessing retinal microcirculation was laser Doppler flowmetry (LDF). In the early 1980s, it began to be more widely used in ...
Alternatively, laser Doppler flowmetry (LDF) can measure blood flow and mean velocity in relative units, and its extension, laser Doppler holography (LDH), can estimate pulsatile retinal flow in ...
