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 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 short PCAs supply the following ( Figure 3 ): (1) the choroid as far as the equator, and (2) the overlying retina to a depth of about 130 μm, including the retinal pigment epithelium and up to the outer part of the inner nuclear layer.

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 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 μm 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.

Posterior ciliary arteries: consist of two sets of arteries; long and short posterior ciliary arteries. These arteries pierce the sclera on the posterior aspect of the eyeball, just lateral to the optic nerve, and go on to supply the sclera, choroid and anterior segment of the eyeball.

Purpose: Malfunction in peripapillary hemodynamics has been suggested to play a major part in the pathogenesis of primary open-angle glaucoma (POAG). The aim of this study was to determine whether topically applied brimonidine can influence blood hemodynamic characteristics associated with the perioptic short posterior ciliary arteries (SPCAs), central retinal artery (CRA), and choroidal.
Orbital Blood Supply Basicmedical Key
The ophthalmic artery has multiple branches which separate into two categories: orbital branches and optical branches. The orbital arteries include the ciliary arteries, central retinal artery, and muscular arteries. [1]
Vasculature of the eye Complete Anatomy
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 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.

She described the development of the cilioretinal artery by the enlargement of an anastomosis of one of the posterior ciliary arteries with a small branch from the hyaloid artery on the disc. This anastomosis is located in man at the edge of the optic disc where traces of the short ciliary arteries enter the nerve near the lamina cribrosa in.

short posterior ciliary arteries from six to twelve in number, arise from the ophthalmic artery as it crosses the long posterior ciliary arteries, two for each eye, pierce the posterior part of the sclera at some little distance from the optic nerve. anterior ciliary arteries are derived from the muscular branches of the ophthalmic artery.

The short posterior ciliary arteries are branches of the posterior ciliary arteries which are, in turn, branches of the ophthalmic artery. Each eye has multiple small short posterior ciliary arteries (16-20) which pierce the sclera adjacent to the optic nerve.
