Abstract

O2-sensitive platinum electrodes were employed to measure preretinal vitreous oxygen tension (PPVO2) in lightly anesthetized monkeys at varying levels of PaCOCO2. PPVOPVO2, which is chiefly an index of oxygen availability in the inner-retinal layers, varies directly with PACOCO2. These variations in PPVOPVO2 with PaCOCO2 are related to retinal blood flow changes (previously described) and to the Bohr effect. The role of inner-retinal oxygen consumption rate (VOO2.) under these conditions is also discussed.
