ophthalmic vein

The superior or the inferior ophthalmic vein. The superior ophthalmic vein drains the upper portion of the orbit, while the inferior ophthalmic vein drains the lower portion; both veins empty into the cavernous sinus inside the skull. Both veins are valveless and anastomose with the facial vein thus interconnecting the extracranial and intracranial venous systems.
