Anterior ciliary artery

Anterior Ciliary Artery

The arteries of the choroid and iris. The greater part of the sclera has been removed.

The Anterior Ciliary Artery is one of the seven branches of the Ophthalmic Artery that supplies blood to the front part of the eye. It is a crucial component of the eye's vascular system, providing oxygen and nutrients to the sclera, conjunctiva, and the anterior part of the iris.

Structure

The Anterior Ciliary Artery typically arises from the muscular branches of the Ophthalmic Artery. It travels forward, around the eye, to reach the anterior part of the eye. There are usually two to seven Anterior Ciliary Arteries, which pierce the sclera at different points, around the equator of the eye, and supply the anterior part of the uvea, mainly the ciliary body and the iris.

Function

The primary function of the Anterior Ciliary Artery is to supply blood to the front part of the eye. This includes the sclera, the conjunctiva, and the anterior part of the iris. It also plays a role in the regulation of intraocular pressure.

Clinical significance

Damage to the Anterior Ciliary Artery can lead to serious eye conditions, such as glaucoma, uveitis, and retinal detachment. Therefore, understanding the anatomy and function of this artery is crucial in the diagnosis and treatment of these conditions.
