Translaminar pressure difference and its impact on glaucomatous process stability

[...]. Aim of the study. To analyze translaminar pressure difference and its impact on glaucomatous process stability. Objectives of the study: 1. To determine and compare intracranial pressure, translaminar pressure difference in patients with normal-tension glaucoma, high-tensuion glaucoma, ocular hypertension and healthy subjects. 2. To determine the associations between intracranial pressure, translaminar pressure difference, ocular hemodynamic parameters and glaucoma, ocular hypertension. 3. To determine the associations between intracranial pressure, translaminar pressure difference, ocular hemodynamic parameters and structural optic nerve disc and functional visual field parameters. 4. To determine the associations between changes in intracranial pressure, translaminar pressure difference, ocular hemodynamic parametersand changes in structural optic nerve disc and functional visual field parameters. To assess the threshold value of translaminar pressure difference change that could be used to foresee glaucomatous process stability. [...]
