Contour map of the age-related strain change coefficients of the nonlinear regression function (b coefficients in Table 1) for the peripapllary scleral region. Negative values of the strain change coefficient indicate a local increase in scleral compliance with age, while positive values indicate local scleral stiffening with age. Age was significantly associated with peripapillary scleral strain in all but the temporal sector (P<0.05). S, superior; I, inferior; N, nasal; T, temporal; ONH, optic nerve head
