Forming a short single trunk, it passes between the two heads of the Rectus lateralis and through the medial part of the superior orbital fissure, and ends in the cavernous sinus. The ethmoidal veins drain into the superior ophthalmic vein. Vorticose veins also drain into the superior ophthalmic vein.
