ophthalmic vein

one of two venous channels in the orbit, the superior ophthalmic vein and the inferior ophthalmic vein, that communicate with the cavernous sinus. This communication can be a route by which infections spread from outside to inside the cranial cavity.

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.
