Figure 5. Regional Post-BMO Total Prelaminar Volume (in cubic millimeters) Measurement Means, PID Maximums and PIPD (%) Maximums.

Figure 5

Post–BMO Total Prelaminar volume (Figure 1I) is a volumetric parameter that attempts to capture both the posterior deformation of the lamina and the expansion of the neural canal that are central to a “glaucomatous” or “laminar” form of cupping (see Figure 1 for an explanation of these relationships). It incorporates features of (and is related to) the laminar position and neural canal offset parameters outlined in Figures 3 and 4, above. Within each region, measurement mean is the mean of the n=6 right eyes of each animal and is grey scale mapped in cubic micrometers on the left. Physiologic inter-eye difference (PID) Maximum is the upper range of the PID within each region for the n=6 PID values (from the n=6 animals) and is grey scale mapped in cubic micrometers. Physiologic inter-eye percent difference (PIPD) Maximum is the upper range of the PIPD within each region (expressed as percent (%) ) for the n=6 PIPD values (from the n=6 animals) and is grey scale mapped on the right. The 15° radial region maps (Figure 2) are presented in right eye configuration. S, superior; N, nasal; I, inferior; T, temporal.
