Purpose: The etiology of glaucoma is still unknown, though several mechanisms have been proposed to contribute to the changes of the optic nerve head (ONH). The most important known risk factor is increased intraocular pressure (IOP) and consequently, therapies available today focus on lowering IOP. However, there is also evidence that reduced ocular perfusion pressure (OPP) and altered blood flow regulation may play a role in the development and progression of this disease. In the present study, we tested the hypothesis that ONH blood flow is autoregulated during isometric exercise induced changes in mean arterial blood pressure (MAP) and during suction cup induced changes in IOP. We also explored whether blood flow only depends on OPP, or...
