Abstract

Inner-retinal oxygen consumption rate (VOO2) varies with Pacoco2 in monkeys. When Pacoco2 increases, inner-retinal (VOO2 increases, until Pacoco2 reaches approximately 70 mm. Hg. Above this level VOO2 is depressed but never returns to the VOO2 of normocapnia. The most likely explanation for this phenomenon is that the intracellular increase in HCO3- accelerates the citric acid cycle turnover. In hypocapnia, inner-retinal VOO2 is lower than under normocapnia. The most likely explanation for this phenomenon is the accompanying reduction in intracellular POO2
