The main blood supply of the eye arises from the ophthalmic artery, which gives off orbital and optical group branches. Innervation of the eyeball and surrounding structures is provided by the optic, oculomotor, trochlear, abducens and trigeminal cranial nerves. This article covers the anatomy, function and clinical relevance of the vessels and

The branches of the ophthalmic artery comprise the entire arterial supply to the eye. Most commonly the ophthalmic artery branches off of the internal carotid artery, distal to the cavernous sinus, then travels through the optic canal. The ophthalmic artery has multiple branches which separate into two categories: orbital branches and optical branches. The orbital arteries include the ciliary

The retina is supplied by two distinct vascular systems from important branches of the ophthalmic artery: the central retinal artery (CRA) and; the posterior ciliary arteries (PCA). Anatomy of retinal vascularization. Retinal blood vessels from the CRA supply the inner two-thirds of the retinal thickness.

3.2. Introduction to the eye's vascular system. The arterial supply to the eye and orbit is the ophthalmic artery. This artery is a branch of the intracranial portion of the internal carotid artery. Within the orbit it has a tortuous course which is thought to allow eye movements without impairing the blood supply.

Central Retinal Artery: It is the first branch of the ophthalmic artery. It is a terminal branch supplying the inner layer of the retina, and its occlusion can cause sudden visual loss. It travels inferiorly and within the optic nerve sheath to supply the inner two-thirds of the retina. The artery further divides into superior and inferior

Arterial Arcades. Marginal arterial arcade: located 2-3 mm from the eyelid margin, it lies just above the ciliary follicles, either within the tarsus or between the tarsal plate and orbicularis oculi muscle. Peripheral arterial arcade: located within the Müller/inferior tarsal muscles, at the border of the tarsus and those muscles. Venous Drainage

The main vascular supply to the eye is the ophthalmic artery (OA), which is the first branch of the internal carotid artery and the only branch of the internal carotid artery outside the cranium (see Fig. 2). Smaller vascular contributions come from the external carotid artery via the internal maxillary artery and the facial artery.

3.2 The Blood Supply to the Eye and Related Structures. The principal arterial supply of the orbit and the eyeball derives from the ophthalmic artery, the first major branch of the intracranial portion of the internal carotid artery. This branch passes beneath the optic nerve and accompanies it through the optic canal into the orbit.

The ophthalmic and internal carotid arteries, labeled on the Gross 3D anatomy model. The main source of arterial blood to the eyeball comes from the ophthalmic artery ?, one of the branches of the internal carotid. Several arterial branches arise from the ophthalmic artery to supply different components of the eye. Vasculature of the eye.

Purpose: The eyelids have a rich vascular supply, and bleeding may compromise both surgical technique and postoperative results. Generally, it is known that the eyelids contain a marginal and peripheral arcade, but detailed anatomic information is not available. This study therefore was undertaken to determine the detailed anatomy of eyelid vascularity.Method: The common carotid arteries of

The blood supply of the eyelids is derived from the facial system, which arises from the external carotid artery, and the orbital system, which originates from the internal carotid artery along branches of the ophthalmic artery. Thus, the eyelid vasculature represents an anastomosis of the external and internal carotid arteries (Fig 1-36).

Cilioretinal Arteries There are anatomic variations in which an arterial branch originating from the posterior ciliary arteries or choroid, or both, assists the CRA in supplying the inner retinal layers. 3,5 Studies show it is the most common congenital vascular anomaly of the retina, found in 6% to 32% of individuals. 3,6,7 A study using fundus photography and fluorescein angiography (FA) to

This artery supplies the inner layers of the retina. The ophthalmic artery also gives off numerous muscular branches, which as their name suggests, supply the extraorbital muscles. These arteries are quite variable in their origin and number and they reach and supply the muscles that move the eyeball.

The OphA gives off the CRA, which then enters the substance of the optic nerve approximately 10-12 mm posterior to the globe. Within the eye, the CRA divides into superior and inferior arcades. Like the blood-brain barrier, the retinal arteries and arterioles have tight junctions that form a blood-retina barrier.

Abstract. The eyeball and the optic nerve are supplied by the ophthalmic artery and its various branches; these include the central artery of the retina, anterior and posterior ciliary arteries (ACAs, PCAs), and collateral branches to the optic nerve. My anatomic studies on the ophthalmic artery and its branches in man have revealed gross

The human eye is an incredible assembly of unique types of tissues, each of which has its own requirements in terms of blood supply. The major source of blood for the anterior eye is the anterior ciliary arteries, whereas the central retinal artery and the posterior ciliary arteries, both originating from the ophthalmic artery, is the supply for the posterior eye.

Purpose: The aim of the study was to investigate the arterial distribution of the eyelids. Methods: The location, course, length and diameter of eyelid arteries were determined in 19 preserved and latex injected adult male cadaver heads. Results: The diameter of the medial palpebral artery was found to be 1.50+/-0.28mm on the right, and 0.70+/-0.12mm on the left.

Blood vessels wind all throughout your body. They ensure that blood, and the oxygen it carries, reaches all your body's cells and tissues. Arteries carry oxygen-rich blood from your heart to organs and tissues. Veins carry blood back to your heart to pick up more oxygen. And tiny vessels called capillaries connect the arteries to the veins.
