The form of the ocular pulse in anesthetized dogs resembled an arterial pressure tracing. Obstructing the carotid artery reduced the amplitude of the pulse in the ipsilateral eye, but if collateral circulation through the basilar artery remained intact, the pulse soon returned to normal. Division of the basilar artery by itself temporarily increased the pulse amplitude in both eyes, probably reflecting increased collateral circulation through the carotid arteries. A 14% reduction in carotid blood flow or a 4% reduction in carotid blood pressure reduced the amplitude of the ocular pulse by 10% in dogs.
