Alternating strabismus in children and adults, features of its treatment

If a person can not fix a sight with both eyes at the same point, doctors diagnose an alternating strabismus.Usually it is discovered in childhood.Two or three children out of a hundred have a similar pathology.Is it possible to cope with such a vice?How to treat alternating strabismus?

What is alternating strabismus?Symptoms and causes.
Alternating strabismus is also called friendly, convergent or divergent.The second name is strabismus.In all cases it is a question of the same pathology of the eyes, when the organs of vision alternately deviate from the central axis.If one eye looks at the object, and the pupil of the second is facing the nose, this phenomenon is called a convergent strabismus.If the second eye mows in the direction of the temple, we have to talk about the divergent strabismus.
There is such a vice due to incorrect work of the muscles of the eyes.From the normal position, the eyes are deflected alternately.When the eyes are arranged symmetrically, the image enters the center of the organ of vision and merges into the cortical parts of the visual analyzer.If the eye mows, the binocular effect does not occur.The mowing organ of vision is not involved in the process, and soon its function is exhausted( vision falls sharply or disappears altogether).
The reasons for this phenomenon can be both congenital and acquired.Often, strabismus is the result of trauma, stress, severe fright, paralysis.Sometimes, strabism is a complication after infectious diseases( influenza, measles, scarlet fever, diphtheria).It can develop in people with lesions of the central nervous system and somatic anomalies.Strabism often occurs in short-sighted and far-sighted people with a predisposition to astigmatism, with a sudden drop in the vision of one eye, pathology of development and attachment of the eye muscles, retina and optic nerve.
Confirm or refute the alternating strabismus by examining the entire visual system.An experienced ophthalmologist will determine the diagnosis and without special investigation.But now there is an opportunity to verify the presence or absence of pathology with the help of modern methods of computer diagnostics, as well as tests for binocular vision.

Therapeutic treatment methods
Binocular vision can be restored with the help of complex and long-term therapy.It is possible, if the central nervous system is able to coordinate both visual systems( sensory and motor), there is a chance to restore normal position to the eyes.
For the treatment of strobism apply:
- Hardware procedures, which should result in improved vision;
- Diploptic and orthoptic treatment for the regeneration of binocular vision;
- Pleoptic treatment;
- Optical correction( contact lenses or glasses);
- Training on a convergent trainer;
- Procedures for consolidating the achieved results;
- Surgical intervention.
Hardware procedures.The most common device for the treatment of strabismus is synoptophor.With his help, the visual system is forced to see the image binocularly, resuming the normal axes of each of the eyes.Another device that treats strabismus is a heyroscope.Recovers image fusion, partially improves eyesight.A folding stereoscope with a mirror is not the newest device, but sometimes it is used for exercises to form binocular vision and develop fusional reserves.
Diplomatic and orthopedic treatment.The first type of treatment is to resume binocular vision in a natural way.Orthoptic eliminates suppression of sight of the mowing eye, develops fusional reserves, regenerates bifoveal fusion.The second type of treatment is performed on synoptophor.
Pleoptic treatment is a doubled load on the mowing organ of vision.Apply different methods of stimulation with medical computer programs, therapeutic laser.
Optical vision correction - more often used for children.Prescribe wearing glasses that correct the position of eyeballs and improve vision.
When are the surgical procedures used?
With congenital alternating strabismus, ophthalmologists recommend early surgical resolution of the problem - at the age of 2-3 years.Only in this case there is a high chance of a successful outcome.Adults are recommended for surgery if therapeutic methods do not give results within 1-1.5 years or with paralytic strabismus.
Operations are of two types - weakening or strengthening the movement of the muscles of the eyeball.Surgical intervention is subject to one or both eyes.
Binocular vision resumes after such operations rarely, rather they have an aesthetic function.
Operate strabismus under local drip anesthesia, in some cases under general anesthesia.If the operation passes without complications, the patient returns home the same day.Rehabilitation lasts 7-10 days.During this period, physical activity, swimming pool is contraindicated.Recommended instillation of the eyes, exercises on the apparatus, physiotherapy procedures.
Exercises for the eyes, their effectiveness
To eliminate strabismus, you can do it yourself.
Exercises can be done with mild form of strabismus and for prevention, they are referred to the so-called home therapies:
- A healthy eye is covered with a hand or a suitable object, the load is given for mowing.Exercise several minutes a day.
- Pull forward the arm and fix the sight on the index finger.Slowly bring your finger to the nose by 10 cm.
- Remove the eyeball alternately in different directions as far as possible.Do the same thing up and down.
For exercises with children it is necessary to choose a time when the baby is not hungry and does not act up.In such exercises, there is necessarily an element of the game.Use colored cubes and balls, bright pictures and mosaic, other objects.A healthy eye is closed and briefly focuses the child's view on the subject.Then they show color pictures.A bright object is tied to a stick and driven before your eyes.
For older children offer to find differences in pictures, to follow the eyes through the labyrinth.You can throw balls into the basket, hammer nails and do exercises for eyeballs, described above.
Prevention of strabismus
Preventive maintenance of strabismus is carried out since early childhood:
- is regularly visited by the oculist;
- observe the rules of visual hygiene;
- identified eye diseases are treated on time.
- beware of infectious diseases and injuries;
- to regulate eye strain;
- work under the right lighting;
- take care of your eyes.
It is not even possible for an expert to diagnose the alternating strabismus in children and adults.He can be cured only by a qualified ophthalmologist.At the slightest suspicion of strabismus in children or at oneself, it is necessary to contact the doctor immediately.
