A) Porcine specimen glued to the 3D-printed holder at the limbus, with the optic nerve centered. B) Specimen and holder from panel A mounted on the inflation chamber. The chamber was filled with PBS injected from the tubing connection at right and cleared of all air bubbles. C) The inflation chamber was then immersed in a PBS bath and connected to a PBS-filled reservoir, whose height could be manually adjusted to control pressure in the inflation chamber, i.e. the simulated IOP. The inflation apparatus was placed on a rotating stage that had translational degrees of freedom to ensure alignment between the rotation axis and the optic nerve axis.
