Strabismus is a deviation of the visual axis of one of the eyes from the joint fixation point, leading to the loss of binocular vision. Human vision is known to be binocular.
This means that although we perceive visual images simultaneously with two eyes, each of the eyes works by itself, perceiving objects separately.
The brain processes the received information, combining images into one. However, with strabismus, which most often develops in childhood, this mechanism is disrupted.
Unfortunately, parents do not always pay attention to the fact that the child is mowing in time. In addition, fear and some stereotypes of thinking prevent them from taking effective measures in time to eradicate this defect.
This state of affairs is greatly facilitated by some myths generated by people who have little understanding of the essence of the problem. We will try to debunk some of them.
Strabismus is only a cosmetic defect, it does not harm health. This is not true. After all, a mowing child is simply not able to correctly assess the position of objects in space, therefore, the correct perception of the surrounding world is violated. In addition, the vision of the squinting eye deteriorates over time, as the brain does not perceive its signals. As a result, functional blindness (amblyopia) develops.
With age, strabismus will pass - by a year or three. Indeed, the baby's eyes are sometimes squinted due to the immaturity of the nervous system. But this should take place by three months. If the strabismus lasts longer, you should definitely go to an ophthalmologist.
Strabismus is a consequence of the stress experienced. Negative emotions do not cause squint. Most likely, the cause of the disease can be diseases of the nervous system (intrauterine, resulting from birth trauma), affecting the work of the oculomotor muscles. In addition, strabismus develops as a consequence of astigmatism, myopia, or hyperopia.
Strabismus can be treated at any time, there is no need to rush. Unfortunately, this is not the case. It should be noted that the earlier the squint appears, the higher the likelihood of complications (for example, over time, the eye may begin to squint vertically), and the faster blindness may develop (a small child may lose sight within a few months). Therefore, strabismus must be treated as soon as the diagnosis is made, because the earlier treatment is started, the faster and easier it is to achieve results.
There are no glasses or lenses for babies. Yes, glasses for children under one year old are not provided. But sometimes a small patient is prescribed contact lenses if they are needed to treat myopia.
A squint in one eye is better than both. This is a misconception. After all, functional blindness develops precisely when one eye is squinted. If both eyes squint, they both take part in the process of obtaining visualizations. Therefore, one of the initial stages of strabismus treatment is the translation of unilateral strabismus into bilateral.
When treating strabismus, surgery can be dispensed with. This opinion is valid only in cases where strabismus is caused by hyperopia, myopia, astigmatism. If the cause of strabismus is the pathology of the oculomotor muscles, the operation is necessary.
There is laser correction for strabismus. In order to set the eye to its normal position, the surgeon performs an operation, during which some muscles are tightened, while others, on the contrary, are weakened. Such an operation is not yet possible with laser surgery.
Only one operation is needed. Only two operations performed with an interval of four to six months can help completely get rid of strabismus.
Strabismus can be relieved by one type of treatment. No, in the treatment of strabismus, a set of techniques is used.
1. The use of lenses or glasses for vision correction.
2. Covering a healthy eye (occlusion). The purpose of this method is to make the sore eye work.
3. Hardware treatment (retinal light), which improves visual acuity, helping to develop the correct connections between the two eyes.
4. The use of special computer programs designed so that the child's eyes receive a certain load during the game.
These techniques are used to improve vision before surgery, and after surgery, they help the eyes to adapt and consolidate the result achieved during treatment.
