Eye blood supply anatomy. That form the circle of Zinn. These are the short posterior ciliary long posterior ciliary anterior ciliary and the central retinal arteries. Blood leaves the eye via the central retinal vein which travels out of the optic nerve next to the artery before draining into the superior ophthalmic vein.

The ophthalmic artery has multiple branches which separate into two categories. Terminal branches of the lacrimal artery include the superior and inferior lateral palpebral arteries which supply the lateral upper and lower eyelids and conjunctiva. It is continuous with the temporal bone and the pterygopalatine fossa caudally.

The eye is supplied by the ophthalmic artery which is the first branch of the internal carotid artery when it has travelled passed the cavernous sinus. Presentation Layout Embryology of optic nerve Introduction Parts of optic nerve Blood supply Clinical significance 3. 3rd week of gestation.

Runs along the lateral wall of the orbit and supplies the lacrimal gland. There are two circulations of the eye. The eye is contained within the bony orbit of the head.

The ophthalmic artery has numerous branches that supply the muscles that move the eye and surround the eye the eyelid and the eyeball itself. Other branches of the ophthalmic artery sup-ply the lacrimal gland extraocular muscles and lids. Is supplied by the superior hypophyseal and ophthalmic aa.

Long posterior ciliary arteries run a similar course but move further into the eye to supply the anterior aspect of the choroid in addition to the iris and ciliary bodies. Branching pattern as it approaches 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.

Pierces the dural sheaths of the orbital optic n. The retinal in the retina and uveal supplied in humans by posterior ciliary arteries originating from the ophthalmic artery that derived from the internal carotid artery. The eyeball receives arterial blood primarily via the ophthalmic artery.

The major blood supply to the eye is from the external carotid artery Venous blood leaves from the angular vein deep facial vein ophthalmic veins Superficial temporal artery. The branches of the ophthalmic artery comprise the entire arterial supply to the eye. The optic nerve contains the ganglion cell axons running to the brain and additionally incoming blood vessels that open into the retina to vascularize the retinal layers and neurons Fig.

The posterior ciliary arteries which form the blood supply to the cho-roid and the central retinal artery which enters the eye via the optic nerve are branches of the ophthalmic artery Figure 1. But doest supply it its supplied by pial plexus of vessels Intracraneal optic n. Blood Supply The extraocular muscles are supplied mainly by branches of the ophthalmic artery.

The ophthalmic artery gives rise to many branches which supply different components of the eye. The bony orbit is a cavity comprising parts of the lacrimal bone includes fossa for nasolacrimal duct and the maxilla includes caudal foramen of infraorbital canal. The first evidence of primitive eye formation occurs Neural plate destined to form prosencephalon Optic sulcus formation depression Formation of optic vesicle and optic stalk Embryology.

Venous blood is conveyed by the four vorticose veins that drain into the ophthalmic vein. The retina is approximately 05 mm thick and lines the back of the eye. Ophthalmic Artery Artery of Eye Blood supply to Eye Eye Anatomy - YouTube.

The eye is supplied by branches of the ophthalmic artery. The central retinal artery branches off the ophthalmic artery just after it enters the orbit piercing the optic nerve just behind the globe to supply the retina. Blood supply to the visual pathway Intra-ocular optic n.

Supplementary branches of the ophthalmic artery combine the ciliary arteries which branch into the anterior ciliary arteries. Blood supply of the eye. Spinal Cord Grey Matter Brainstem.

Eyeball Blood Supply Eye Anatomy. The ophthalmic artery then branches into the short posterior ciliary arteries which pierce the sclera and supply the choroid up to the equator of the eye.
