The superior ophthalmic vein drains venous blood from structures of the upper orbit. [2] The superior ophthalmic vein forms/represents a connection between facial veins, and intracranial veins. It is valveless. [3] The superior ophthalmic vein is the largest and the most consistently present vein of the orbit. It usually measures 2-10 mm in ...
As a venous sinus, the cavernous sinus receives blood from the superior and inferior ophthalmic veins and from superficial cortical veins, and is connected to the basilar plexus of veins posteriorly. The cavernous sinus drains by two larger channels, the superior and inferior petrosal sinuses , ultimately into the internal jugular vein via the ...
The superior ophthalmic vein is a sigmoidal vessel along the superior margin of the orbital canal that drains deoxygenated blood from surrounding musculature. The ophthalmic artery is a crucial structure in the orbit, as it is often the only source of collateral blood to the brain in cases of large internal carotid infarcts , as it is a ...
The superior orbital fissure is a foramen or cleft of the skull between the lesser and greater wings of the sphenoid bone. It gives passage to multiple structures, including the oculomotor nerve, trochlear nerve, ophthalmic nerve, abducens nerve, ophthalmic veins, and sympathetic fibres from the cavernous plexus.

The supraorbital vein is a vein of the forehead. It communicates with the frontal branch of the superficial temporal vein. It passes through the supraorbital notch, and merges with the angular vein to form the superior ophthalmic vein. The supraorbital vein helps to drain blood from the forehead, eyebrow, and upper eyelid.
