Regulation of Retinal Bloodflow Pressure

Start date: March 29, 2018
Phase:
Study type: Observational

Autoregulation is defined as the ability of a vascular bed to adapt its vascular resistance to changes in perfusion pressure. In the eye, several studies have reported that retinal blood flow is autoregulated over a wide range of ocular perfusion pressures. Large scale studies have shown that reduced ocular perfusion pressure is an important risk factor for the prevalence, the incidence and the progression of primary open angle glaucoma. There is also evidence that autoregulation is impaired in patients with primary open angle glaucoma. To gain more insight into these phenomena in humans is the primary goal of the present study. The present study aims to investigate the pressure/flow relationship as a measure for retinal blood flow autoregulation during an experimental increase in intraocular pressure by the use of the suction cup technique. Retinal blood flow will be measured by Doppler OCT.
