The anterior ciliary arteries are seven small arteries in each eye-socket that supply the conjunctiva, sclera and the rectus muscles. They are derived from the muscular branches of the ophthalmic artery.

Course[edit]

The anterior ciliary arteries branches of the ophthalmic artery and run to the front of the eyeball in company with the extraocular muscles. They form a vascular zone beneath the conjunctiva, and then pierce the sclera a short distance from the cornea and end in the circulus arteriosus major. Three of the four rectus muscles; the superior, inferior and medial, are supplied by two ciliary arteries each, while the lateral rectus only receives one branch.
