Left: Schematic representation of the radial compressive stress P_LC originating within the lamina cribrosa as a consequence of the action of IOP, CSFp and scleral tension acting on it. P_LC acts as external pressure on the translaminar segments of the central retinal artery and vein. Right: Magnitude of the radial compressive stress P_LC computed using the nonlinear elastic model described in [41] for various IOP and CSFp levels (black dots) and interpolated using using a second order polynomial function (green surface).
