Definition
The central retinal vein is a branch of the superior ophthalmic vein that drains venous blood from the retina. It accompanies the central retinal artery.
Course
The central retinal vein is a short vessel formed by the convergence of several small veins on the optic disc. It enters the optic nerve and exits it again about 10 mm after leaving the eyeball. It drains the venules and capillaries of the retina. Depending on the individual, the vein drains either into the superior ophthalmic vein or directly into the cavernous sinus.
Clinic
Retinal vein occlusion results in a buildup of blood in the retina, leading to progressive visual impairment.
