Amblyopia in children - the types and treatment of the disease
When our children grow up, it is very important to conduct timely diagnostics of health, including eye health. In this article, we will talk about eye disease - amblyopia in children.
Amblyopia in children is a functional or reversible decrease in vision. With such loss of vision, one eye is poorly or almost not involved in the visual process. With this disease, the eyes see different pictures, different image quality and the brain simply can not combine them into one whole.
Amblyopia of the eye is characterized by the fact that it changes in the brain, namely in the visual cortex. Changes arise from distorted visual information that comes from the eyes. Ultimately, the improvement and development of neurons that are responsible for vision slows down, so even if all causes of the disease are eliminated, it remains low.
Types and forms of the disease
Depending on the level of vision drop in children with amblyopia, the following types can be distinguished:
- of low degree( visual acuity 0.8-0.4);
- of medium degree( visual acuity 0.3-0.2);
- high degree( visual acuity 0.1-0.05);
- very high degree( visual acuity 0.04 and below).
By the mechanism of origin there is amblyopia refractive and disbinocular. Refractive arises, as a rule, because of untimely appointment or intermittent wearing of contact lenses, glasses with ametropia, which create indistinct images on the fundus. Disbinocular begins due to the violation of binocular vision. Basically, it occurs with strabismus, i.e.when the complicity of one eye in the visual process is much reduced.
It should be noted that congenital cataracts or throat can serve as a basis for the development of obscurative amblyopia, which is difficult to treat. To eliminate it, timely surgical intervention( for example, corneal transplantation or the removal of congenital cataracts) is necessary. Children also have a one-sided and two-sided form.
The causes of the disease
The causes of amblyopia are very diverse. Often it occurs with such diseases as astigmatism, hyperopia, cataract, nystagmus and corneal opacity. However, the most common is strabismus. It is worth noting that this disease can be a consequence, as well as the cause of strabismus. This occurs when one eye is very low in sight( below 0.4-0.3) at which fusion of images is impossible.
Amblyopia in children or adults can form if their relatives suffer from strabismus, as well as in people who have never had vision problems. Like any disorder in the body, amblyopia is important to detect as early as possible, because over time the disease is only aggravated."Launched" amblyopia can lead to a complete inhibition of visual function in the amblyopic eye.
It is important to note that this ailment can not be detected independently and this disease will not pass by itself. Therefore, it is recommended to undergo a diagnostic examination at least once a year.
Treatment of amblyopia in adults and children
For effective results, much depends on patience and a clear implementation of all the recommendations of a doctor - an ophthalmologist. After a comprehensive examination, an individual method of treatment is developed for the patient. Treatment of amblyopia interacts with the treatment of the disease that caused it. The main thing is the constant wearing of contact lenses or glasses.
Also the main method is occlusion, i.e. Exclusion of a healthy eye from the visual process, using special plastic occluders, which attach to the spectacle lens. In the complex treatment of amblyopia include various types of stimulation( photo-stimulation, light, frequency-contrast, etc.), as well as various therapeutic techniques( vacuum massage, massage glasses, laser infrared and ultrasound therapy, magnetoeropy).
