The long posterior ciliary arteries arise from the ophthalmic artery. There are usually two arteries.


The long posterior ciliary arteries extend anteriorly and pierce the sclera of the eyeball near the optic nerve. They travel anteriorly in the suprachoroid layer of the choroid, in the medial and lateral horizontal planes of the eyeball.


There are no named branches; however, the long posterior ciliary arteries divide in the ciliary body and form an anastomosis with the anterior ciliary arteries. This forms the major arterial circle of the iris (Forrester et al., 2008).

Supplied Structures

The long posterior ciliary arteries supply the choroid, ciliary body and iris of the eyeball.

The long posterior ciliary arteries arise as trunks from the ophthalmic artery, pierce the globe near the optic nerve, and run forward to the ciliary body, where they anastomose to form the major arterial circle.
