Abstract
To evaluate the effect of increased intraocular pressure (IOP) on the corneal shape of human cadaver eyes, eight cadaver eyes found to be unsuitable for transplantation were assessed for overall integrity. The epithelium was debrided, the eye placed into an artificial orbit, and a 30-gauge needle was inserted into the vitreous cavity. The IPO was altered as necessary. The surface contour was assessed at different pressure levels. Keratomeric analysis was made to examine the dioptric effects of varying IOP. An elevation analysis was performed to determine the corneal locations that conformed to the pressure adjustments. Results lead to the conclusion that the cornea does not uniformly conform to IOP variation.
