Primary open-angle glaucoma (POAG) patients and normal individuals underwent an ophthalmic evaluation as well as blood pressure, height, and weight measurements. Intracranial pressure (ICP) and OPP were calculated using proxy mathematical formulas to attain indirect surrogate parameter values. The TLPD was calculated as intraocular pressure minus ICP. The association between the variables was evaluated using linear and non-linear regression analysis and the correlation estimated with Pearson\u2019s correlation coefficient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The sample included 50 POAG patients and 25 normal subjects.
