Strabismus in children
Strabismus in children — not a harmless cosmetic defect, which may pass with age itself. If you notice your child has even a slight squint, you should see a doctor.
What is strabismus? Types of strabismus
With normal vision the visual axis of both eyes to focus on the subject under consideration. In case of strabismus, the visual axis on the same subject do not agreedeviation of the eyes (one or both) to the side, up or down. Usually this is due to the weakness of the muscles of the eyeball, which, in turn, can be caused by various causes (we will discuss them later).
Strabismus in children can be congenital or acquired. Congenital strabismus is manifested in children immediately after birth or in the first six months of life, purchased most often from one to three years.
Also strabismus is vertical and horizontal. Horizontal strabismus is more common and is convergent (one or both eyes looking towards the nose) and divergent (one eye or both eyes looking towards the temples). Vertical strabismus with a deviation downward or upward.
Strabismus is monocular and altenroxel. When monocular strabismus squints one eye only, the person ceases to use it, and the vision of the squinting eye is greatly reduced. When altenroxel strabismus people use both eyes, but alternately.
Also happens to be friendly and paralytic strabismus. Strabismus in children is most often friendly. When the movement of the eyeballs occurs in full, the primary and secondary angle of strabismus are equal, no strabismus and disorders of binocular vision. When paralytic strabismus is paralyzed or one or more oculomotor muscles are damaged.
Causes of strabismus
Why there is strabismus in children? Causes of strabismus are rooted in physiology of the child's body. A small child is not able to see with two eyes — it is not formed binocular vision. Primitive binocular vision is formed by the child for 2-4 months and continues to form up to four years. Therefore, the inability of the infant to focus on the object with both eyes at an early age is natural, but if infant does not pass the squint — is an alarming sign.
Strabismus in children can be the result astigmatism, nearsightedness (congenital or acquired), hyperopia, central nervous system diseases, severe infectious diseases (especially those accompanied by high fever), trauma (physical or mental), eye diseases (so called secondary strabismus), intoxication during pregnancy, hereditary predisposition.

Conservative treatment methods are designed to increase visual acuity. If strabismus caused by myopia, hyperopia or astigmatism, the child is prescribed glasses ; sometimes glasses help to completely correct strabismus in children. This is also true for secondary strabismus: when you cure a disease that caused strabismus, the child will stop "mowing."
Also, the child is taught to combine the image with the left and right eyes into one image. To do this, courses special treatment in the form of games and/or used method of occlusion (healthy eyes closed by a bandage, the child gets used to rely on squinting eyes). Type, regularity and duration of carrying of a bandage is prescribed by a doctor!
The choice of surgical methods depends on the depth of lesions of the visual system and the type of strabismus. The operation serves to solve problems that can not be solved by conservative methods. It does not replace conservative therapeutic methods, but is accompanied by them. The operation can be done at any age, and the sooner the better the chances for success.
Strabismus in children is quite a serious problem. It can cause psychological complexes (often children with strabismus become the object of ridicule of their peers) and significant visual loss. Strabismus in children is not going away, so it is important to identify and begin treatment .
