Average birefringence measurements calculated from EPS-OCT PR/UD radial area and ring scans plotted with respective regional neurotubule density (ρRNFL) for subjects (A) 57204 (B) and 1853. Area and ring scans of PR/UD measured within angular regions that were sampled for neurotubule density surrounding the ONH were averaged together within the respective angular section region resulting in an equal number of PR/UD measurements for every ρRNFL value. N, nasal; T, temporal; S, superior; I, inferior
