Short posterior ciliary arteries


The short posterior ciliary arteries, around twenty in number, arise from the medial posterior ciliary artery and lateral posterior ciliary artery, which are branches of the ophthalmic artery as it crosses the optic nerve.[1]

Course and targetEdit

They pass forward around the optic nerve to the posterior part of the eyeball, pierce the sclera around the entrance of the optic nerve, and supply the choroid (up to the equator of the eye) and ciliary processes.

Some branches of the short posterior ciliary arteries also supply the optic disc via an anastomotic ring, the circle of Zinn-Haller or circle of Zinn, which is associated with the fibrous extension of the ocular tendons (common tendinous ring (also annulus of Zinn)).
