The retinal venule is medium in size. Passing a few millimeters along the border of the retina, it successively forms the anterior venule, and then divides into two lateral parts which, crossing, form the posterior venule. Each of the processes reaches the epithacal space behind the pigment layer. A small number of branches end outside the choroid and pass into the retinal capillaries. The posterior venule is partially located inside the vitreous body and takes part in the formation of the veins of the retinal sector. Several larger venular and retinal arteries emerge from the vein onto the pigment-reticular stripe, which lies between the vessels.
