title: The regional distribution of retinal circulation.
abstract: The retinal circulation of the cat has been studied in vivo by high-speed cineangiography and post mortem by indian ink injection. Flow patterns in the arterial tree, relative volume inflow per unit area, and capillary circulation times were recorded. The retinal circulation shows progressive slowing of linear flow rate in arterioles and capillaries on passing centrifugally from the optic disc to the periphery; this is largely responsible for the reduced perfusion rate.
