What does ophthalmic vein drain into?

What does superior ophthalmic vein pass through?
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.
What does superior ophthalmic vein mean?
The superior ophthalmic vein is formed by the joining of the angular and supraorbital veins within the orbit (Figure 11-11). It passes below the superior rectus muscle and crosses the optic nerve to the upper part of the superior orbital fissure, where it leaves the orbit to empty into the cavernous sinus.
What is ophthalmic vein thrombosis?
Disease. Superior ophthalmic vein thrombosis (SOVT) is a rare vision- and life-threatening complication with many underlying etiologies such as infectious and inflammatory orbital disease, trauma, neoplasm, and a hypercoagulable state.

The ophthalmic veins are the two vessels that drain the venous blood from the structures of the orbit into the cavernous sinus.
Where does ophthalmic vein pass through?
The vein runs posteriorly, passing under the eyeball and over the surface of the inferior rectus muscle. The inferior ophthalmic vein courses through the superior orbital fissure, just below the common tendinous ring (annulus of Zinn).
Where does ophthalmic vein come from?
The superior ophthalmic vein originates around the superomedial orbital rim just posterior to the trochlea. It arises from the union of the two small branches of the facial and supraorbital veins. The former enters the orbit via supraorbital notch, while the latter passes through the orbital septum.
