Pressure-volume relationships of the normal canine eye.
Changes in intraocular volume and pressure induced by Schiøtz tonometry were measured and utilized to calculate the in vivo rigidity of the normal canine eye. Rigidity was found to be dependent upon intraocular pressure (IOP) and tonometer weight; rigidity assumed a parabolic relationship to IOP, decreasing from 0.0754 at 5 mm of Hg IOP to 0.0274 at 55 mm of Hg IOP and gradually increasing to 0.0333 at 100 mm of Hg IOP.
