It pierces the optic nerve close to the eyeball, sending branches over the internal surface of the retina, and these terminal branches are the only blood supply to the larger part of it.
The central part of the retina where the light rays are focussed after passing through the pupiland the lens is a circular area called the macula. The center of this circular area is the fovea. The fovea and a small area surrounding it are not supplied by the central retinal artery or its branches, but instead by the choroid
What else can I help you with?
What is a retinal artery occlusion?
Retinal artery occlusion refers to the closure of the central retinal artery and usually results in complete loss of vision in one eye.
What is the function of the central retinal artery?
The function of central retinal artery is that it does absoulutely nothing.....jk.......the artery helps the eye with its central visionn by the fovea and optic nerve n disk...!to be continued..........
Contain many blood vessles which nourish retina?
Central Retinal Artery
How does blood flow in the human eye?
Blood flow in the human eye is primarily provided by the central retinal artery, which branches from the ophthalmic artery. This artery supplies oxygen and nutrients to the inner layers of the retina, while the choroidal circulation, supplied by the ciliary arteries, nourishes the outer layers of the retina and the retinal pigment epithelium. Venous blood is drained through the central retinal vein, which exits the eye alongside the central retinal artery. This vascular system is crucial for maintaining the health and function of the eye.
Is retinal vein occlusion related to root canal work?
Retinal Vein OcclusionThe central retinal vein is the venous equivalent of the central retinal artery, and like that blood vessel can suffer from occlusion (central retinal vein occlusion), similar to that seen in ocular ischemic syndrome. Since the central retinal artery and vein are the sole source of blood supply and drainage for the retina, such occlusion can lead to severe damage to the retina and blindness, due to ischemia (restriction in blood supply) and edema (swelling). It can also cause glaucoma.
What are the artery and vein of the eye?
AnswerThe central retinal artery and vein they control movement of the eye and send blood to eye
What is the recovery rate for branch retinal artery occlusions?
Branch retinal artery occlusions (BRAO) have a recovery rate of 80% where vision is restored to 20/40 or better.
How is retinal artery occlusion diagnosed?
RAO is diagnosed by examination of the retina with an ophtalmoscope.
What is retinal vein occlusion?
Retinal vein occlusion refers to the closure of the central retinal vein that drains the retina or to that of one of its branches.
What causes pale optic?
A pale optic nerve is usually not a good sign. It is usually seen in people with advanced glaucoma, after a central retinal vein or artery occlusion, or with certain optic neuritis cases.
What is the prognosis for central retinal visual acuity?
The prognosis for central retinal visual acuity is poor with only about one-third of patients recovering useful vision.
What causes pale optic nerve?
A pale optic nerve is usually not a good sign. It is usually seen in people with advanced glaucoma, after a central retinal vein or artery occlusion, or with certain optic neuritis cases.
