Arteries Ciliary Posterior Long

Long posterior ciliary arteries

The long posterior ciliary arteries (a.ciliares posteriores longae) are two arteries that pass through the back of the orbit and supply the ciliary layer of the retina. They are branches of the internal carotid artery and belong to the system of cerebral arteries.

The long posterior ciliated arteries begin from the internal carotid artery in the posterior part of the orbit, pass through the orbit and empty into the retina. They are divided into two branches: one that runs along the back edge of the eye and another that runs along the front of the eye.

Functions of the posterior long ciliary arteries:

Supplying the retina with oxygen and nutrients necessary for its functioning.
Supports blood flow in the ciliary layer of the retina, which is important for transmitting information from photoreceptors to the optic nerve.
Protecting the retina from damage and infection.

Diseases of the posterior long ciliary arteries can lead to decreased visual acuity and other vision problems. Therefore, it is important to monitor the health of these arteries and undergo regular medical examinations.
