After branching from the ophthalmic artery, it passes anteriorly through the superomedial orbit. It travels medial to the trochlear nerve. With the supratrochlear nerve, the supratrochlear artery exits the orbit through the supratrochlear notch (variably present), medial to the supraorbital foramen. It then ascends on the forehead. [citation ...
The supraorbital artery is a branch of the ophthalmic artery. It passes anteriorly within the orbit to exit the orbit through the supraorbital foramen or notch alongside the supraorbital nerve , splitting into two terminal branches which go on to form anastomoses with arteries of the head.
It exits the orbit through the supratrochlear notch or foramen. [3] It then ascends onto the forehead beneath the corrugator supercilii muscle and frontalis muscle. It finally divides into sensory branches. [citation needed] The supratrochlear nerve travels with the supratrochlear artery, a branch of the ophthalmic artery. [2]
The supraorbital nerve is one of two terminal branches - the other being the supratrochlear nerve - of the frontal nerve (itself a branch of the ophthalmic nerve (CN V 1)). [1] It exits the orbit via the supraorbital foramen/notch before splitting into a medial branch and a lateral branch. It innervates the skin of the forehead, upper eyelid ...
The supraorbital artery branches from the ophthalmic artery as it passes over the optic nerve. The supraorbital artery passes anteriorly along the medial border of the superior rectus and levator palpebrae and through the supraorbital foramen to supply muscles and skin of the forehead.
Middle part transmits: Superior and inferior divisions of the oculomotor nerve (CN III), nasociliary nerve (lies between the two divisions of oculomotor nerve) and abducent nerve; Medial part transmits: Inferior ophthalmic veins and sympathetic nerves arising from the plexus that accompanies the internal carotid artery

The superior ophthalmic vein is the only orbital vein whose course generally parallels the course of an orbital artery: it has a similar course as the ophthalmic artery [1] (however, the latter instead exits the orbit through the optic canal). [2] Within the orbit, the superior ophthalmic vein passes posterior-ward alongside the ophthalmic artery.
