VITREOUS BODY OXYGEN-TENSION FOLLOWING EXPERIMENTAL BRANCH RETINAL VEIN OBSTRUCTION

Abstract

Either temporal or nasal superior and inferior retinal veins in 1 eye of rhesus monkeys were obstructed with xenon photocoagulation. This resulted in large areas of nonperfused retina adjacent to normal retina in the same eye. Intraretinal neovascularization (new vessels in the retina) developed following the absorption of retinal hemorrhage and edema. Microelectrodes were used to measure and compare vitreous body O2 tensions over the nonperfused and the normal retinal areas. There was no significant difference between the O2 tension measurements in the same eye.
