Strabismus

What is strabismus?
 
Strabismus is a visual defect in which the parallels of the eyes become disrupted and look in different directions. One eye can look straight, and the other can slide inward, outward, upward or downward. Slip can be permanent or occasional. Sometimes the floating eye can look flat and the other can slip. Strabismus is a common condition among children. It may also occur in later life. The distribution between men and women is equal. It can show the same family transition. In spite of this, many strabismus individuals may not be identified with strabismus.
 
»How do eyes work together?
 
Both eyes look at the same spot in normal vision. It then creates a three-dimensional image by combining these two images of the brain. This three-dimensional image gives us a sense of depth. If there is a slip in the eye, two different pictures are sent to the brain. In a small child, the brain neglects the appearance of the floating eye and perceives only the normal, well-sighted image. Thus, the child lost sense of depth. When strabismus occurs in adult patients, double vision usually occurs. Because the brain is used to seeing the images coming from both eyes and can not neglect the view from the floating eye.
 
»Lazy eye
 
If both eyes are parallel during childhood, there is good vision. The brain perceives the image of the good eye and neglects the image of the lazy eye. This is seen in almost half of the children with strabismus. Treatment of amblyopia: Treatment of eye laziness should be made until 8-10 years of age. Then the treatment is not possible. There are several treatment methods. The first of these is the treatment with the good eye closed and the vision of the lazy eye is strengthened. Another method of treatment is the treatment in private clinics in the form of sessions with instruments called CAM. In the form of this treatment, the child is asked to sit on the head of a tool, to draw over the lines, to draw or solve puzzles. It consists of at least 20 sessions. A third treatment method is drugs. The atropine group is based on the operation of the other eye by dropping the drug.
If treatment is delayed, lethargy becomes permanent. As a rule, the sooner the lazy eye is treated, the better the result. For this purpose, children should undergo an ophthalmologic examination at least once a year.
 
»Causes of strabismus
 
The exact cause of strabismus is unknown. There are six muscles that control their movement by sticking to the outside of each eye. Two muscles in each eye pull the eye to the right or left. The other four muscles move the eye up or down at certain angles. All the muscles must work together in a certain equilibrium so that the eyes can be parallel and focus on a specific target. In order for the eyes to move together, the muscles in both eyes must be compatible. The brain controls the eye muscles.
 
• Cerebral palsy (no-oxygen-free mold during birth);
• Down syndrome;
• Hydrocephalus;
• Strabismus is more common in children with problems such as brain tumors.
 
Cataract or eye injuries can also impair vision and cause dizziness.
 
»Symptoms of strabismus
 
The basic symptom of strabismus is a straight-eyed eye. Sometimes the children close their eyes in the sun or bare their heads to use both of their eyes.
 
»How is strabismus diagnosed?
 
Strabismus is diagnosed as a result of an eye examination. All children are recommended to undergo a visual examination before entering the age of four. If the family has a history of strabismus or lazy eye vision can be tested before. Babies' eyes usually look like a cross. The nasal root of small children becomes large and flat, and also a skin fold on the nose of the eyes. They make it look as if there were crosses in the eyes. As the child grows, this pseudo-strabismus disappears. There is no improvement in the case of a child with real squint. The ophthalmologist distinguishes between real and pseudo-strabismus.
 
»How is strabismus treated?
 
Aim of treatment for strabismus:
 
• Protect vision;
• Parallels the eyes;
• Is to provide the view so depth in two eyes.
 
After a complete ophthalmologic examination, the ophthalmologist determines the appropriate treatment. In some cases, glasses may be recommended for your child. Sliding with the given glasses can be improved completely or partially. Apart from this, surgery may be necessary to parallelize eyes or remove cataracts. To strengthen the lazy eye, it is often necessary to close the healthy eye.
 
»Common types of strabismus
 
Esotropia is the most common type of strabismus in infants. Children with slip cannot use two eyes together. In most cases, eyes can be paralleled with surgery in the early period. The tension of the muscles in one or two eyes is adjusted during the surgical procedure. The tight inner muscles are removed and removed. Thus, the eyes are provided outward. Occasionally, the muscles of the outward-looking muscles can be increased by increasing the tension and correcting the strabismus. Surgery does not necessarily need to be done to the sliding eye.
