It will not be a secret for anyone that we live in the centuryCardiovascular diseases. A wise saying is known: »The age of a person is the age of his vessels». Often, the age-related wear of the vessels makes itself felt in the form of so-called sclerosis. What it is? Imagine that you wanted to drink water? Your actions are simple: take a glass, open the tap, ... but the water is very weak trickle, and then ceases to flow. You call the plumber, but he says that simply fixing the crane can not solve the problem. And the reason is simple - the pipes are very old, there is a lot of rust and other dirt on the walls, which narrows the lumen of the pipe. Need to change the pipes. So the age-related wear of the vessels - sclerosis - is the gradual narrowing of the lumen of the vessels, as a result of which the blood flow slows down considerably on it. In the end, in the narrowest place of the vessel a blood clot forms - a thrombus. Sometimes such thrombus can completely clog the vessel - cause its thrombosis. There are situations when the obstruction of the vessel occurs as a result of a sharp contraction - a spasm even without sclerosis. But most often the sclerosis of the vessel is its organic defeat in combination with spasm, that is, functional damage.
To date, vascular diseases of the eyeGradually come out on top among the causes of incurable blindness. There is a mass of vascular diseases. And there's no point in enumerating them or describing them in detail, because, practically all of them are a consequence of a vessel's obstruction or a significantly slowed flow of blood through it. Depending on the degree of this circulatory insufficiency, vascular diseases of the organ of vision proceed acutely or chronically.
Acute circulatory insufficiency in the vesselsRetina accompanied by spasm, embolism, thrombosis. These changes can develop gradually, becoming chronic. It should also be mentioned that chronic circulatory failure in the retinal vessels arises as a result of vascular damage in diabetes mellitus, atherosclerotic dystrophy of the macula (mainly in elderly people) and other conditions.
From insufficiency of blood circulation in the eye inFirst of all, the most important shell of the eye - the photosensitive layer of the retina - suffers. After all, all the functions of the eye are ultimately determined by the normal working capacity of the retina. The structure of the retina is very difficult. Without going into details, the inner shell of the eye - the retina in its origin is a continuation of the brain and is a highly specialized nervous device designed to perceive light stimuli. In fact, the processes that originate in the retina are a chain of the most complex, still insufficiently studied photochemical transformations, leading to the fact that light stimulation is completed by the formation of a certain visual impression in our minds. The eye not only associates visual images, but acts as a kind of receiver of light energy and color effects, which are the causative agents of brain activity. It is through the endings of the optic nerve - the receptors, as through special anatomical inputs, the energy of light is brought from the outside world into various parts of the central nervous system.
Studies of biophysicists have shown that inPhotosensitive devices of the optic nerve are hidden tremendous possibilities. Scientists have proved that by regulating the light regime, it is possible to influence many vital processes in the body. Light irritation affects, for example, the pulse frequency, fluctuations in blood pressure, filling blood vessels, secretory activity of the stomach and pancreas. Under the influence of light waves, the secretion of hormones of the adrenal cortex changes, metabolism, sexual function. According to some researchers, light waves of different length can either inhibit or enhance the development and growth of tumors.
Obviously, maintaining a reliable blood supply to the retina is the most important task not only for preserving the vision, but also for the normal functioning of the whole organism.
Physiologists give a clear definition: »The retina is part of the brain that has been pushed to the periphery.» Just like the brain, it is very poorly tolerated by oxygen starvation, which occurs when there is insufficient blood circulation.
So, if you can not get drunk freshWater, you will probably solve the problem by calling plumbing. However, a plumber was not yet born who could replace the vessels that feed the retina.
Therefore, as far as possible from your side, try not to worsen the condition of your blood vessels with an unhealthy lifestyle, which includes not only bad habits, but to protect and train them.
