Abstract
A new empirical one-parameter ocular rigidity function accurately represents the pressure-volume relationship of the corneoscleral shell over a wide range: where P<sub>1</sub> is the initial intraocular pressure and P<sub>2</sub> the pressure after an alteration ΔV in the intraocular volume. Unlike Friedenwald's coefficient of ocular rigidity, the proportionality constant k in the cube root ocular rigidity function is insensitive to changes in intraocular pressure. Its value for enucleated human eyes is approximately k=0.03 mm Hg<sup>⅓</sup> μ1<sup>−1</sup>. The cube root ocular rigidity function is as faithful to experimental data as more complicated two- or three-parameter models.
