Studies on Retinal Oxygenation
Mammalian retina is partially vascularized. The capillaries, supplied by the central retinal artery, extend as deep as the inner nuclear layer, while the outer layers remain avascular. However, the photoreceptors inner segment contains huge mitocondriae. This fact indicates intense oxidative activity at this level, and the oxygen used for this process presumably diffuses from choriocapillaries through the Bruch’s membrane. This particular mode of oxygenation should determine a structured metabolism based on a combination of oxidative and anaerobic capacity.
