Amblyopia in the absence of treatment can lead to complete loss of vision. Degree of amblyopia.

Amblyopia appears in childhood when the vision is not completely formed. If amblyopia is not treated, the child's vision will develop incorrectly. Every year, the child's brain will increasingly ignore the image of the sick eye.

As a result, in the absence of proper treatment, amblyopia can lead to complete loss of vision.

Causes of the disease

Amblyopia usually develops when the ability of each of the eyes to look right to the proper focus is different, for example, the vision of one eye has signs of myopia, and the vision of another is absolutely normal. The baby's brain, when faced with a fuzzy image, comes from a sick eye, just ignores it. If this process continues for a long time (several months or even years), the eyesight of the patient's eyes will gradually deteriorate.

Another cause of amblyopia is strabismus. Incorrect position of one of the eyeballs does not allow focusing the eyes on this object and causes obscurity of perception. As a result, the child's brain gradually begins to ignore the image from the sight of the strabismus, which leads to deterioration of vision. Due to the displacement of one of the eyes of amblyopia, it is often called the illness of a lazy eye.

Children may also experience vision problems due to the significant difference in eye refractive index. The most common cause of this is cataract, the presence of small amounts of blood and other foreign substances inside the eye.

How to determine the presence and degree of amblyopia

It is necessary to check every child of preschool age for the presence of amblyopia. As a rule, a school physician examines three indicators that guarantee the health of the baby's eyes:

  • The absence of a significant difference in the refractive ability of the eye;
  • Good vision;
  • Normal ability to rotate the eyes.

If there is any suspicion of at least one of them, the doctor recommends that you sign up for an ophthalmologist. If there is any suspicion that the child may have vision problems, you should contact a specialist even if the child has already been examined by a school doctor.

The presence of amblyopia of any degree from one of the parents is a risk factor for the development of such a disease in a child. As a rule, parents can not accurately determine the presence of visual impairment in their child, so you should always remember that the earlier a child will be examined by a specialist and the earlier treatment will be started, the more favorable the prognosis.

How is amblyopia treated?

The easiest way to treat amblyopia is to force the brain to perceive an image that is obtained from a sick eye, for example by applying a bandage on a healthy eye. Obligatory condition is wearing bandage constantly: this event will ultimately completely restore vision. Wearing a bandage can be delayed for weeks or even months until full recovery.

When a child begins to see the outside world only with the help of the patient's eyes, vision begins to recover. Once the doctor has determined that vision has come to fruition, you should stop wearing the bandage. Some children may once again begin to experience vision problems that will require the re-use of the bandage.

In the case of a light-chain chemopilosis, the doctor may recommend special eye drops (atropine) for the bandage. Using atropine erases a picture in a healthy eye, forcing the brain to perceive the image of the patient.

Most children with amblyopia need to wear glasses that help to focus their eyesight. If anything interferes with normal light penetration inside the eye, the doctor may recommend an operation to restore normal light transmission, and in the case of strabismus - plastic eye muscles.

Prospects for treatment

If the causes causing amblyopia have been eliminated and treatment has begun at an early stage of the disease, then most children are fully cured of this illness.

Since amblyopia at the age of 7-9 years is much heavier for treatment, diagnosis is very important at an earlier age. It is necessary to follow the doctor's advice, which often causes difficulties, as many children refuse to wear a bandage.

The use of atropine as an alternative method of treatment makes it possible to achieve greater success in the treatment of amblyopia.
