Data for each group are reported for “All Eyes” as well as for “Hi-ESF and for “Non-Hi-ESF” sub-groups (Hi-ESF eyes were defined to be those eyes in which the magnitude of the ESF subregion was ≥ 100 μm in at least one ONH sector – (see Methods). Within the Hi-Myo eyes (Right Panel), data in bold red with asterisks are significantly different from the Non-Hi-Myo value (Left Panel) for the same sub-group

^***(p < 0.001
