Ophthalmic artery
Ophthalmic Artery
The Ophthalmic Artery (pronunciation: op-thal-mic ar-ter-y) is a major blood vessel that originates from the Internal Carotid Artery. It is responsible for supplying blood to the eye and its surrounding structures.
Etymology
The term "Ophthalmic" is derived from the Greek word "ophthalmos", which means "eye". The term "Artery" is derived from the Latin word "arteria", which means "windpipe, artery".
Anatomy
The Ophthalmic Artery arises from the Internal Carotid Artery just as it is emerging from the cavernous sinus. It travels forward within the optic canal, above and lateral to the Optic Nerve. It then enters the orbit where it gives off several branches to supply the structures of the eye and its adnexa.
Branches
The Ophthalmic Artery gives off several branches including the Central Retinal Artery, Lacrimal Artery, Ciliary Arteries, and Muscular Branches. These branches supply the retina, lacrimal gland, ciliary body, and extraocular muscles respectively.
Clinical Significance
The Ophthalmic Artery is of clinical significance as it can be involved in various ocular conditions such as Retinal Artery Occlusion, Ischemic Optic Neuropathy, and Ocular Ischemic Syndrome. It is also of importance in interventions such as Ophthalmic Artery Chemosurgery for the treatment of retinoblastoma.
