The supraorbital artery branches from the ophthalmic artery after it passes through the optic canal and passes medially over the optic nerve. It travels anteriorly in the orbit by passing superior to the eye and medial to the superior rectus and levator palpebrae superioris. It then travels with the supraorbital nerve between the periosteum of the roof of the orbit and the levator palpebrae superioris to enter the supraorbital foramen. After passing through the supraorbital foramen, it bifurcates into a superficial and deep branch. Its terminal branches anastomose with the supratrochlear artery and frontal branch of the superficial temporal artery.
This artery may be absent in 10% to 20% of individuals.
