The ciliary arteries are divisible into three groups, the long posterior, short posterior, and the anterior.
- The short posterior ciliary arteries from six to twelve in number, arise from the ophthalmic as it crosses the optic nerve.

- The anterior ciliary arteries are derived from the muscular branches of the ophthalmic artery.
