The signs (symptoms) of strabismus
When strabismus on bifurcation will complainadults but not children. For children squint uncommon complaints of double vision because of good adaptive abilities of the brain. Children should undergo vision screening studies to identify potential problems early. The younger the child, when he found a squint, and treatment is started, the greater the chance of normal vision. The most common symptoms are:
Eye deviation (a) to the temple or nose
Angled or tilted position of the head
Double vision (in some cases)
Causes of strabismus
The main measure is the prevention of strabismustimely diagnosis. If strabismus is usually the ability to see normally retains only the eye that carries vision. Eye deflected to the side, sees over time getting worse and worse, it suppresses the visual function. Therefore, treatment should begin as soon as possible.
The cause of strabismus may be injured andbrain disease, trauma (fear). Eye interaction can be broken due to the farsightedness and nearsightedness. Sposobstvyuet appearance of strabismus infectious diseases (measles, scarlet fever, diphtheria, flu, etc.)
Who can develop strabismus
Strabismus develops due to violationscoordinated work of the eye muscles. Most often it develops in childhood due to improper development of binocular vision (coherent vision with two eyes). At the age of 2-3 years, finally secured a joint activity of both eyes. That's when there is the risk of strabismus. In congenital hyperopia greater than 3.0 diopters, the child develops a friendly squint. One eye may be leading, while the other eye sight will drop for no apparent reason. However, this is explained by the fact that the image of the object in the squinting eye will not fall into the center hole of the retina, due to its deviation from its normal position. This low vision squinting eye is called amblyopia - blindness from inactivity.
Strabismus in children - children strabismus
Strabismus is one of the most common eye diseases in children (found that the prevalence of strabismus is 2% of the total number of births).
Apart from cosmetic defects, strabismusaccompanied by a serious disorder functions. The presence of this disease negatively affects the mind, shaping the character of children and is a great functional weakness.
In the absence of binocular visiondisturbed perception of the outside world, the child is not able to determine the spatial relationship of the surrounding objects. As a result, it may lag the physical and mental development of the child. Often this pathology is observed even from the hospital. And contribute to its development of preterm labor, fetal hypoxia, neuropathological nature of the disease.
Sometimes there is a disparity of right and left eyes - one of them sees worse. In this case, the brain tends to "switch off" from the work of the weaker eye.
There are two main forms of strabismus - friendly and paralytic.
There are also atypical forms of strabismus.
From true strabismus should be distinguished imaginary or latent squint.
