Anterior ciliary arteries

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

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.

These arteries supply the conjunctiva & sclera.
