Evidence for Autoregulation in the Human Retinal Circulation

  • R. W. Ross Russell


There is a growing interest in neurogenic influence on the cerebral circulation and a variation between species with respect to vascular innervation has been the cause of much of the confusion in the past. As a small contribution to the subject it may be of interest to report some simple observations on the only accessible human arterioles which do not appear to have any nerve supply—retinal branch arteries. Adrenergic nerve fibers have been detected in the central retinal artery in the optic nerve but not in the retina itself.
