The central retinal vein (retinal vein) is a short vein that runs through the optic nerve leaves the optic nerve 100 mm from the eyeball and drains blood from the capillaries of the retina into either superior ophthalmic vein or into the cavernous sinus directly. The anatomy of the veins of the orbit of the eye varies between individuals and in some the central retinal vein drains into the superior ophthalmic vein and in some it drains directly into the cavernous sinus.
