AD, axial eye diameter; OA, orbital aperture diameter; TD, transverse eye diameter. “Growth residuals” were calculated using least-squares regressions. For each variable, the adult value was regressed against the neonatal value in order to calculate an “expected” adult value. Residuals were calculated from these equations. Since the predicted y value estimates the adult eye size for a given eye size at birth, the residuals approximate how much growth occurs postnatally as opposed to prenatally (positive values indicate more postnatal growth; negative growth residuals indicate more prenatal growth.
