Short Posterior Ciliary Arteries

The posterior ciliary arteries are branches of the ophthalmic artery, and much variation can occur in their distribution. 11 The short posterior ciliary arteries arise as 1, 2, or 3 branches that then form 10 to 20 branches. They enter the sclera in a ring around the optic nerve and form the arterial network within the choroidal stroma (Figure 11-3)..

The short posterior ciliary arteries are a number of branches of the ophthalmic artery. They pass forward with the optic nerve to reach the eyeball, piercing the sclera around the entry of the optic nerve into the eyeball. Anatomy

The ocular circulation is supplied by two sets of arteries. The central retinal artery is the main source of supply to the inner retina. The posterior ciliary artery (PCA) is the main source of blood supply to the optic nerve head (ONH), the choroid up to the equator, the retinal pigment epithelium (RPE), the outer 130 ฮผ of the retina (and, when a cilioretinal artery is present, the entire.

The short posterior ciliary arteries arise from the ophthalmic artery. There are usually about seven arteries. Course The short posterior ciliary arteries extend anteriorly towards the eyeball and divide into 15-20 branches (Standring, 2016). They then pierce the sclera of the eyeball near the optic nerve.

The posterior ciliary artery divides into the short and long posterior ciliary arteries that penetrate through the sclera and provide blood flow to the posterior uveal tract. Blood flow to the retina remains constant regardless of intraocular pressure, systemic blood pressure, and is independent of sympathetic autoregulation..

The posterior ciliary artery (PCA) circulation is the main source of blood supply to the optic nerve head (ONH), and it also supplies the choroid up to the equator, the retinal pigment epithelium (RPE), the outer 130 ฮผm of retina (and, when a cilioretinal artery is present, the entire thickness of the retina in that region), and the medial and lateral segments of the ciliary body and iris.

The meaning of SHORT POSTERIOR CILIARY ARTERY is any of 6 to 10 arteries that arise from the ophthalmic artery or its branches, pass to the posterior part of the eyeball while surrounding the optic nerve, and enter or divide into branches entering the sclera to supply the choroid and the ciliary processes.

Purpose: Malfunction in peripapillary hemodynamics has been suggested to play a major part in the pathogenesis of primary open-angle glaucoma (POAG).
