What is a retinal artery?
Retinal artery, often referred to as central retinal artery, is the main source of blood for the interior of the retina. It passes into the eyes from behind, along the same path as the eye nerve and the vein of the retina. Nutrients and oxygen are transmitted to the retina through this blood vessel.
retina gets blood on two different routes. Choroids blood vessels, which carry between 65% and 85% of the total blood flow to the eye, supply the outer part of the retina through the blood. The blood supply in the inner part of the retina is complemented by central retinal artery. The blood then leaves this inner part of the retina of the central vein retina. Four branches of arteries distract blood throughout the inner retina and eventually branch further into smaller blood vessels and capillaries. Capillary is divided into three layers.
The retina is a very important part of eye anatomy. It is located in the rear of the eye, images that enter the pupil are projected on this surface, which is extremely photouping. Both bars that are sensitive to light, and cones that are sensitive to color areplaced in the retina. The information collected by these sensors travels along the optical nerve to the brain where the information is processed and captured as vision.
In order to remain healthy, the retina requires certain nutrients that are supplied to it through a retinal artery. Vitamin A deficiencies were associated with reducing the function of the retina, because both rods and cones require this vitamin. One of the common sources of vitamin A is the orange pigment in carrots known as beta-carotene. The myth that carrots are good for the vision of man, as it turned out, is not at all, and increasing the consumption of this vegetable can increase retinal activity.
disruption along the artery of retina, such as clots or tears, can cause serious and permanent damage to the retina. Emergency surgery is performed if possible to maintain vision when these disturbances occur. Obeling artery occlusion, which is a relatively rare retinal failureY is one of the conditions that requires rapid medical attention. The chances of maintaining vision after the diagnosis of this disease are between 21% and 35%.
