Schematic representation of geometry and boundary conditions of the elasticity problem for the lamina cribrosa. The upper surface (i.e., ζ = hlc/2) faces the interior of the eye globe and is subject to the intraocular pressure (IOP). The lower surface (i.e., ζ = − hlc/2) faces the optic nerve canal and is subject to the retrolaminar tissue pressure (RLTp). The lateral surface (i.e., s = Rlc) is connected to the sclera and experiences the scleral tension T.
