The 7 anterior ciliary arteries are derived from the muscular branches of the Ophthalmic Artery.

Course

They run to the front of the eyeball in company with the extraocular muscles, 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. Two Ciliary Arteries supply each rectus muscle, except the lateral rectus, which only receives one branch. Thus, we can see there are 7 branches of anterior ciliary arteries that supply each set of extraocular muscles.

Supplies

These arteries supply the conjunctiva & sclera.
