Figure 4.  .

TSNIT plot of the mean maximum principal strain for the eight circumferential sectors at 45 mm Hg (assuming zero deformation at 5 mm Hg and a 40 mm Hg IOP elevation) in the peripapillary and mid-peripheral regions for all 20 individual eyes from 10 human donors. Confidence limits of the sector means are not shown, because the autocorrelation function applied to the sample point data in the overall analysis is not appropriate for application to data from individual eyes. T, temporal; S, superior; N, nasal; I, inferior.
