Blood supply of the eyelids The main arterial blood supply. Blood supply to the orbital arises primarily from the ophthalmic artery - the first branch off of the internal carotid as it emerges from the cavernous sinus on the medial side of the clinoid process. Except for central retinal artery which supplies the inner retina almost the entire blood supply of the eye comes from the uveal vessels.

An ophthalmic artery and a central retinal artery an artery that branches off of the ophthalmic artery provide blood to each eye. Additional branches of the ophthalmic artery include the ciliary arteries which branch into the anterior ciliary arteries. The ophthalmic artery has many branches which may be separated into 2 groups.

The internal and external carotid arteries are important vessels because of their blood supply to the orbit cranial base and dura lining the cranial fosse and the cranial nerves. These blood vessels enter and leave through the back of the eye. There are two circulations of the eye.

This is a branch of the internal carotid artery arising immediately distal to the cavernous sinus. The ophthalmic artery gives rise to many branches which supply different components of the eye. Blood to the bulbar conjunctiva is primarily derived from the ophthalmic artery.

However the circulation of the bulbar conjunctiva and palpebral conjunctiva are linked so both bulbar conjunctival and palpebral conjunctival vessels. The ophthalmic artery also branches into the lacrimal artery which supplies the lacrimal gland and the lateral portion of the eyelid. Aspect of the lid and form the Marginal and peripheral palpebral arcades.

Similarly ophthalmic veins vortex veins and a central retinal vein drain blood from the eye. Superior. More videos available on httpAnatomyZon.

Lateral aspect of eyelids. Each rectus muscle receives blood from two anterior ciliary arteries except for the lateral rectus muscle which receives blood from only one. The main blood supply of the eye arises from the ophthalmic artery which gives off orbital and optical group branches.
