What is an ophthalmic artery?
Ophthalmic artery is responsible for distribution of oxygenated blood to mening, orbital structures and facial areas. It comes from the internal carotid artery of distal and branches to smaller arteries such as retina, sacrimal, supraorbital and ethmoid arteries. Outbursting in the ophthalmic artery can lead to retinal damage and can cause sudden and serious loss of vision. It is the first branch that is based on the inner carotid artery, either just before or in most cases, immediately after leaving the cavernous sinus, located on the skull base. Ophthalmic artery helps to supply blood to orbital structures such as eyes, eyelids and extraocular muscles; Meninges that are brain and spinal cord membranes; and the area of the nose and face.
The first artery that Branch from the ophthalmic artery is a central retinal artery that travels inside the fibrous membrane just below the optical nerve and supplies the retina with blood. Others are the rear ciliary arteries that branched to suppose the choroid of the blood, and the tear artery that cIt sets up along the side rectus muscle to supply the mucous membrane that covers the scteror. Lakrimal artery also distributes blood into the eyelids and the tear gland, which is responsible for the production of tears.
other arteries that are ventilated from the ophthalmic artery are the rear and front ethmoid arteries. The rear ethmoid artery supplies blood to the rear ethmoidal dunes as it branches into the nose through the back ethmoid channel and the anterior ethmoid artery supplies the anterior and medium ethmoid cavity. Both of these busting blood to meninges are also responsible for the vulture. Supraorbital artery distributes blood to the front sin, the scalp and the muscles and skin on the forehead.
Any kind of obstruction, such as a blood clot that blocks or reduces blood flow in the ophthalmic artery, can affect eyesight. Depending on how serious obstacle can lead to blurred vision or temporary or permanent loss of vision. FluorineEscein angiography, which is an X -ray of the bloodstream, can help see an obstacle before causing serious damage. During this process, sodium fluorescein solution is injected into the blood and is monitored when it gets into the retina to determine if there is an obstacle.
