How can a retinal reading affect my eyesight?

The retina is the inner wall of the eyeball. There are photoreceptors on it. The most important part of the retina is the macula. This is where most of the photoreceptors are located, which transmit light stimuli to the brain via nerve impulses. These are then processed into images in the brain. The retina is therefore essential to vision, and problems with the retina are serious because they directly affect vision.

Photoreceptors are rods and cones, i.e. sensory cells that react differently. In this way, the chopsticks ensure that we can find our way around in the night and that we can recognize shadows and outlines. The suppositories, on the other hand, are important in light conditions so that the eye can recognize and differentiate colors. The macula enables sharp vision, which is why it contains most of the uvula and rods.

With age, the eye changes, the vitreous humor, which consists of water, loses water and therefore becomes smaller. Under certain circumstances, this can put pressure on the retina and tear it. Other risk factors are severe myopia, various inflammations in the eye, tumors or cataracts. Such a tear is often a harbinger of retinal detachment. Fluid can collect behind the crack and separate the retina, which is only loosely on the wall of the eye and not grown together with it, from its supply layer. The photoreceptors would then no longer function and would die. The person would not even feel pain because there are no pain receptors on the retina. Since a retinal detachment has to be surgically reattached to the dermis as quickly as possible, risk groups must watch out for other signs. Without treatment, there is a risk of complete blindness within a short period of time.

A hole can be lasered relatively well, as a result of which the edges of the hole are scarred with the wall of the eye. This means that no more water can get under the retina. However, a later replacement cannot be ruled out.

If the retina is detached, the sensory cells located there often die within a few days. Therefore, it is very important to act quickly after the symptoms appear. In around 90% of those affected, the retina can be put back on permanently after the operation. However, the scarring can lead to a renewed detachment of the retina. At the same time, however, the operation may not restore full visual acuity.

Signs of retinal detachment are flashes of light due to the pull on the retina or soot rain due to bleeding, etc. Do not hesitate to consult your health optician if you are unsure. If the suspicion is confirmed, he will refer you to an ophthalmologist or an eye clinic as soon as possible.
