Figure 2: Laser speckle flowgraphy images. LSFG snapshot of (a) a healthy eye and (b) a glaucoma eye. LSFG uses the mean blur rate as an indicator of blood flow. The colormap shows blood-flow-related information in the optic disc with the right-hand-side scale bar, where the blue color indicates lower blood flow and the red color indicates higher blood flow.
