[Electron microscopy study of relations between prolongations of dopaminergic amacrine cells and blood vessels in the rat retina].
This immunohistochemical study by electron microscopy has shown the presence of tyrosine hydroxylase immunoreactive processes in more or less close contact with capillaries located in the two plexiform layers of the rat retina. These results, as compared to the literature on the innervation of small blood vessels in the brain, suggest that a dopaminergic innervation is modulating the retinal capillaries' vasomotricity.
