Ciliary arteries explained

Ciliary arteries
Latin:	arteriae ciliares

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 artery as it crosses the optic nerve.
• The long posterior ciliary arteries, two for each eye, pierce the posterior part of the sclera at some little distance from the optic nerve.
• The anterior ciliary arteries are derived from the muscular branches of the ophthalmic artery.
