Association between Systemic Hypertension and Ocular Perfusion Pressure in an Adult Population of North Karnataka, India: A Cross-sectional Study

Journal of Clinical and Diagnostic Research
Introduction: Glaucoma, a major cause of irreversible blindness, is influenced by Intraocular Pressure (IOP) and ocular blood flow. Systemic hypertension may affect the risk of developing glaucoma by influencing Ocular Perfusion Pressure (OPP), although ...

A comparative analysis of the postural and diurnal ocular perfusion pressure of young healthy individuals of different ethnicities

African Vision and Eye Health, 2018
Purpose: Ocular perfusion pressure (OPP) regulates the flow of blood to the optic nerve and is determined by the interaction between intraocular pressure (IOP) and blood pressure (BP). Low OPP increases the incidence of primary open-angle glaucoma (POAG).
