(A) Correlation between the average retinal nerve fiber thickness (RNFLT) and the average MBR over the entire optic disk (MBR_D) in myopic glaucoma patients (Y = 1.6767X + 41.844; r = 0.5324, P = 0.0008). (B) Correlation between MD of Humphrey SITA 30-2 program and MBR_D in myopic glaucoma patients (Y = 0.8673X − 26.646, r = 0.5797, P = 0.0002).
Abbreviations: MBR, mean blur rate; MBR_D, average MBR over the entire optic disk; MD, mean deviation.

(A) A fundus photograph showing a typical myopia-type optic disk. The disk is oval and is tilted to the temporal side with crescent peripapillary atrophy. (B) The color-coded map of the optic nerve head. The colors in this map represent the time averages of MBR over one heartbeat. (C) The disk area was divided into the vessel area and tissue area by LSFG analyzer. The white area represents the vessel area, and the black area represents the tissue area of the optic disk. (D) The elliptical area where MBR was determined by LSFG was set at the outer edge of the myopic optic disk manually. Measurements were taken for the superior, temporal, inferior, and nasal quadrants.
Abbreviations: MBR, mean blur rate; LSFG, Laser speckle flowgraphy.

Comparisons of MBR of the entire optic disk area between control and glaucoma group. The color scale bars in Figure 2A and B show the degree of MBR. The proportions of cool colors in the optic disk, which represent low MBR, are increased in the map of the glaucomatous eye rather than those of the control. (A) A color-coded map of ocular fundus of a control eye. The eyes in control group have myopic disk without glaucomatous visual field loss. (B) A color-coded map of ocular fundus in a glaucomatous eye. (C) Comparisons of MBR_D between two groups. There are significant differences in these parameters between control and glaucoma groups.
Notes: *Glaucoma group significantly different from control group (Mann–Whitney U test; P < 0.05)
Abbreviations: MBR, mean blur rate; MBR_D, average MBR over the entire optic disk.
