| ciliary arteries | Arteries supplying the iris, conjunctiva, choroid, and ciliary body. The anterior ciliary arteries originate in the ophthalmic and lacrimal arteries and supply the iris and conjunctiva; the short posterior ciliary arteries originate in the ophthalmic artery and supply the choroid; the long posterior ciliary arteries originate in the ophthalmic artery and supply the iris and ciliary process.
