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]
Orbital Blood Supply Basicmedical Key
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.

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.

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.
Orbital Blood Supply Clinical Gate
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.

The posterior ciliary arteries are usually paired branches arising from the ophthalmic artery, one medial and one lateral, each giving off a number of branches that supply the uvea 1. Close to the optic nerve, are the short posterior ciliary arteries, usually numbering 16-20; these supply the posterior part of the choroid. Further from the.

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 ciliary muscle is an important part of the eye that contributes to a person's ability to view objects clearly at varying distances. [1] [2] [3] [4] Go to: Structure and Function The middle layer of the eyeball, called the vascular tunic, is composed of the choroid, ciliary body, and iris.

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.

Short Posterior Ciliary Arteries
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.

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.

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 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 μ of the retina (and, when a cilioretinal artery is present, the entire.

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.
