The light-absorbing retina has an exceptionally high oxygen demand, which imposes two
conflicting needs: high rates of blood perfusion and an unobstructed light path devoid of …

The oxygen distribution in the retina of six anesthetized macaques was investigated as a
model for retinal oxygenation in the human retina in and adjacent to the fovea. Po2 was …

Maintenance of an adequate oxygen supply to the retina is critical for retinal function. In
species with vascularised retinas, such as man, oxygen is delivered to the retina via a …

The retina has a very high energy demand but lacks an internal blood supply in most
vertebrates. Here we explore the hypothesis that oxygen diffusion limited the evolution of …

The survival of the retina and optic nerve is dependent on an adequate supply of oxygen
and nutrients to fuel the metabolic processes that are vital for tissue homeostasis and …

The oxygen supply to the retina in man and most mammals is derived from both the retinal
and choroidal circulations. However, some mammals have only a partially vascularized …

The purpose of this study was to investigate the oxygen distribution and consumption in the
pigmented Long-Evans rat retina in vivo during dark and light adaptation, and to compare …

purpose. To measure the intraretinal oxygen distribution and consumption in the fovea, the
parafovea, and the inferior retina in the monkey eye and determine the influence of graded …

Most teleost fishes possess a unique system for tissue oxygen supply, where oxygen is
delivered to the retina at partial pressures that exceed one atmosphere, providing a steep …

purpose. To make the first quantitative assessment of the rate of oxygen consumption in high
oxygen-consuming layers of both the outer and inner retina of the rat in vivo. methods …
