The long posterior ciliary arteries are arteries of the head. They are two in number.
[edit] Course
They pierce the posterior part of the sclera at some little distance from the optic nerve, and run forward, along either side of the eyeball, between the sclera and choroid, to the ciliary muscle, where they divide into two branches.
These form an arterial circle, the circulus arteriosus major, around the circumference of the iris, from which numerous converging branches run, in the substance of the iris, to its pupillary margin, where they form a second (incomplete) arterial circle, the circulus arteriosus minor.
[edit] Target
The long posterior ciliary arteries supply the iris, ciliary body and choroid.
