Displaced volumes plotted against three intraocular pressure levels are used for the calculation of a regression line, the slope of which represents a linear volume‐pressure relationship. This slope was greater in eyes of young then in eyes of elderly subjects but was not influenced by the initial intraocular pressure. The volume displaced by applanation corresponding to a pressure change, as calculated in this study, was larger than expected if an average coefficient of ocular rigidity of 0.0215 was used.
