Full Answer
The superior ophthalmic vein is a prominent vein of the orbit that is seen on CT and may be enlarged or tortuous in various disease entities. Formed in the anterior part of the orbit by the union of the angular, supraorbital and supratrochlear veins. The mean diameter of the vein is 2 mm and normal sizes range from 1 to 2.9 mm 2.
The superior ophthalmic veins may be hyperdense on CT due to thrombosis, including in cases of orbital cellulitis. Which of the following is most likely to be seen in the orbits on MRI in patients with spontaneous intracranial hypotension?
Enlargement of the superior ophthalmic vein (SOV), although usually considered a sign of carotid-cavernous fistula, may be found with other disorders. Patients with Graves orbitopathy, orbital pseudotumor, and a parasellar meningioma as the cause of an enlarged SOV as seen on computed tomography are …
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 superior ophthalmic vein is a vein of the orbit around the eye. It begins from the angular vein and the supraorbital vein, and passes through the superior orbital fissure to drain into the cavernous sinus.
orbital cavityPathology. The superior ophthalmic vein originates in the superior inner angle of the orbital cavity and travels with the superior orbital artery to drain into the cavernous sinus (Figure 1). It is the vein responsible for most of the venous drainage of the orbit.

The ophthalmic veins are the two vessels that drain the venous blood from the structures of the orbit into the cavernous sinus. Namely, they are the superior ophthalmic vein and the inferior ophthalmic vein, with the former being much larger than the latter.
The supraorbital artery supplies the periosteum of the frontal bone, the skin of the forehead, as well as the superior rectus and levator palpebrae superioris muscles. Its terminal branches form anastomotic networks with their contralateral counterparts; the supratrochlear and superficial temporal arteries.

the orbitThe inferior ophthalmic vein is a vein of the orbit around the eye. It receives veins from many structures. It divides into two branches, one of which ends in the pterygoid plexus through the inferior orbital fissure, and the other which ends in the cavernous sinus through the superior orbital fissure.
The superior and inferior ophthalmic veins drain into the pterygoid venous plexus and cavernous sinus. The cavernous sinus drains posteriorly into the petrosal sinuses (superior and inferior).
The ophthalmic artery emerges from the internal carotid artery. This is usually just after the internal carotid artery emerges from the cavernous sinus. In some cases, the ophthalmic artery branches just before the internal carotid exits the cavernous sinus.
Anatomy. The superior orbital fissure is a bony cleft found at the orbital apex between the roof and lateral wall. It is a communication between the orbital cavity and middle cranial fossa and is bounded by the greater wing, lesser wing and body of sphenoid.
The authors suggest that some carotid-cavernous fistula cases be occluded by retrograde embolization via the SOV route.
The dilated SOV may be well demonstrated by MRI, CT and ultrasound scanning. The etiological diagnosis of enlarged SOV can be made in combination with the associated findings. The authors suggest that some carotid-cavernous fistula cases be occluded by retrograde embolization via the SOV route.
