The retina is the thinnest layer between the vitreous and the choroid of the eyeball. How much this thin tissue permeated by the vessels supplying it determines how much. It depends on her proper operation how and what we see, because she is responsible for processing images obtained through the pupil. Violation of the integrity of this layer can lead to loss of vision. Any injury can damage such a delicate structure as the retina. Treatment should be started as soon as you notice a decrease in vision.
Retinal Diseases
The quality of vision depends on the blood supply to the retina. The vessels that feed it can narrow. The retina of the eye, the treatment of which in this case depends on the causes of these changes, begins to lack blood supply and, as a result, becomes less elastic. Which can lead to its rupture.
In addition to narrowing, the vessels of the retina can become dilated and wriggle, clog, and lead to swelling of the eye. Retinal diseases are possible for various reasons. They can provoke:
- injuries, damage to the brain and eyeball;
- hereditary diseases of the retina;
- eye diseases: hyperopia / myopia, inflammatory diseases of the eye itself;
- diseases that provoke negative changes in the tissues of the eyeball: diabetes, meningitis, hypertension, kidney disease and infectious diseases;
- age-related changes after 50 years.
Most common retinal diseases
- Retinal detachment and rupture. A disease characteristic of people with moderate to high myopia. Weakened vision contributes to dystrophy of the retina and under adverse conditions (trauma, infection) leads to its detachment.
- Complications of diabetes. Diabetic retinopathy is the most severe eye lesion in advanced diabetes. The vessels and retina are affected. Treating a common disease helps keep your vision low.
- Age-related lesion of the macula. In old age, macular degeneration is possible - the site of the greatest visual acuity of the eye. Proper nutrition and lifestyle will push the negative age-related changes. And this will help to rule out this disease.
- Retinitis is a common inflammation of the retina. As a rule, it happens as a complication after infectious diseases.
- Hypertensive retinopathy - a consequence of hypertension, a retinal tumor, retinal hemorrhage, etc.
Retinal Disease Prevention
There is a certain risk group among people who may have diseases of the retina. A prerequisite for their development may be:
- myopia;
- diabetes;
- infectious diseases (flu, etc.);
- hereditary diseases of the retina;
- negative age-related changes after 50 years;
- hypertonic disease.
It is extremely important for these people to be attentive to the state of their vision, to be checked regularly (at least once a year) by an ophthalmologist. Retinal problems begin gradually, especially if delamination occurs in the lower half of the eyeball. A person begins to complain about the "veil" before his eyes, about the "flashes" and sparks that prevent him from seeing. Thus, the rupture of the finest tissue, such as the retina of the eye, manifests itself. Treatment should be taken immediately by contacting a doctor. A timely surgical operation or laser therapy allows you to stop retinal detachment and preserve vision. In less urgent cases, medication helps.
To maintain vision, you need to carefully consider the state of your health. The general healthy background of the state of the body allows you to prevent visual impairment and notice its deterioration in time. Do not delay the visit to the ophthalmologist if you have any problems. Even if this is only a temporary decline, the doctor will simply prevent your eyes. And this is never superfluous.
