What is artery in the eye?
The ophthalmic artery has branches that enter the eye (optic branches) and orbital branches. The orbital branches include: Lacrimal Artery: The second and largest branch of the ophthalmic artery. It enters the orbit and travels alongside the lacrimal nerve to supply the lacrimal gland.
What causes artery occlusion in the eye?
Causes. Usually, the blockage comes from a blood clot. The clot may form in the retina or travel there from another part of the body. The blockage also can happen after a piece of fatty plaque plugs the artery.
What is atherosclerosis eye?
Arteriosclerotic retinopathy: Retinal disease caused by arteriosclerosis. In this condition, the arterioles (small arteries) in the retina become partially blocked because of thickening of their walls.
Can retinal artery occlusion be cured?
There is unfortunately no cure for a retinal artery occlusion and treatments are limited in being able to improve blood flow and lower eye pressure.
What causes arterial damage?
Atherosclerosis is thought to happen in areas of the arteries that have turbulence, with unsteady and swirling blood flow, but other factors such as hypertension (high blood pressure), infections, and chemicals can damage the artery walls.
Can stress cause retinal artery occlusion?
Stress and the Retina Chronic stress poses a mostly indirect threat to the retina. For example, older patients who have vascular health conditions such as high blood pressure are already at risk for serious retinal conditions such as age-related macular degeneration or retinal vein occlusion.
What increases the risk of retinal artery occlusion?
The risk factors and demographics of retinal artery occlusion are similar to ischemic stroke and include several modifiable risk factors: Obstruction of the retinal vascular lumen by an embolus, thrombus or inflammatory/ traumatic vessel wall damage or spasm . Giant cell arteritis may also be associated with this condition.
What is the artery and vein of the eye?
Blood supply and drainage of the eye Orbital group. This artery arises from the ophthalmic artery near the optic canal. It runs with the lacrimal nerve to supply the lacrimal gland. Optical group. These arteries branch from the ophthalmic artery near the optic nerve, and run anteriorly on both sides of the eyeball. Venous drainage. The central retinal vein runs through the optic nerve.
Where do the retinal blood vessels enter the eyeball?
The retinal blood vessels are the central retinal artery and vein, and their branches. The arteria centralis retinæ and its accompanying vein pierce the optic nerve, and enter the bulb of the eye through the porus opticus.
What is the treatment for retinal vein occlusion?
Branch retinal vein occlusion treatment guidelines include stopping fluid from leaking from vessels and treating the patient with appropriate medications. An ophthalmologist may suggest a laser procedure to stop fluid from leaking from the vessels. They may also choose to use medications injected into the eye.
