What does superior ophthalmic vein mean?
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.
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.
Where do ophthalmic veins drain?
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 superior petrosal sinus connects to the transverse and sigmoid sinus.
What does superior ophthalmic vein drain into?
The superior ophthalmic vein courses in the superior orbit from the anterior medial corner to the posterior lateral wall to enter the superior orbital fissure, where the vein drains into the cavernous sinus (Figure 2.67).
What is superior orbital fissure?

cavernous sinus
The superior ophthalmic vein courses in the superior orbit from the anterior medial corner to the posterior lateral wall to enter the superior orbital fissure, where the vein drains into the cavernous sinus (Figure 2.67).
What is deep facial vein?
The deep facial vein passes between the facial vein and drains into the pterygoid plexus anterior to the masseter muscle. The pterygoid plexus in the infratemporal fossa receives an emissary vein from the cavernous sinus in the middle cranial fossa through the foramen ovale.
Where is superior orbital fissure?
What is orbital apex syndrome?
Orbital apex syndrome (OAS) involves cranial neuropathies in association with optic nerve dysfunction. Orbital apex syndrome is symptomatically related to superior orbital fissure syndrome and cavernous sinus syndrome with similar etiologies. The distinction is the precise anatomic involvement of the disease process.
What is ophthalmic disease?
The leading causes of blindness and low vision in the United States are primarily age-related eye diseases such as age-related macular degeneration, cataract, diabetic retinopathy, and glaucoma. Other common eye disorders include amblyopia and strabismus.
