In children, the brain will automatically suppress the images generated by deviating vision, and only present the clear images presented by the frontal eye. In this way, only single-eye vision is left without three-dimensionality, and even causes amblyopia .
Some strabismus are caused by other eye or body lesions, such as infections, vascular lesions of the brain, tumors, etc., which lead to nerve numbness and strabismus; a few diseases such as mitochondrial diseases, myasthenia gravis , thyroid disease, , etc. can cause muscle lesions and strabismus; head trauma or eye socket fractures may also cause sequelae of strabismus; in addition, visual deprivation strabismus may also occur when vision loss is lost in monocular eyes.
Younger children have not yet developed their face shape and nose bridge, so their appearance looks asymmetrical between the eyes, which will improve as they mature, and will not affect the development of visual function. This situation will gradually improve with age and changes in face shape. It is called "pseudostril".
The eye position of a newborn is still unstable, but there is still no normal eye position after 6 months of age. You should be treated by an ophthalmologist, because strabismus may make the brain accustomed to using one fixed eye, and the other eye will be suppressed and amblyopia will occur; even if the brain can take turns using two eyes, the three-dimensional sense cannot be established.
If strabismus is not treated in time, it will not only affect the appearance, but may also cause functional problems such as amblyopia or three-dimensional loss of sense. Early detection and early treatment is very important. The goal of treatment is to avoid amblyopia, rebuild the eye position, and promote the development of visual function (three-dimensional sense). Usually, is applied to the glasses of or surgery is a necessary treatment method.
