ögonartärens

Ögonartärerna, also known as the ophthalmic arteries, are a pair of small arteries that branch off from the internal carotid arteries. They are the primary blood supply to the eye and its surrounding structures. Each ögonartär enters the orbit through the optic canal, accompanying the optic nerve.

Inside the orbit, the ögonartären ramifies into numerous branches that supply vital components of the eye. Key branches include the central retinal artery, which penetrates the optic nerve and supplies the inner layers of the retina. Other significant branches nourish the choroid, ciliary body, iris, and extraocular muscles. These vessels are crucial for maintaining the health and function of the eye, providing oxygen and nutrients while removing waste products.

Disruptions to the blood flow in the ögonartärerna or their branches can lead to serious visual impairments. Conditions such as ophthalmic artery occlusion can result in sudden vision loss, while narrowing or inflammation of these arteries can contribute to progressive visual decline. Understanding the anatomy and function of the ögonartärerna is therefore essential in diagnosing and treating various ophthalmological conditions.
