What causes intermittent exotropia?

summary

Intermittent exotropia refers to the exotropia of the big foot. In fact, many people have exotropia, which is within the control range, so they will not show exotropia. Some parents will say that their children sometimes strabismus and sometimes do not strabismus. In fact, this is the characteristic of intermittent exotropia, which is controllable. When intermittent exotropia loses control, it will show exotropia. Today, let me study with you the reason of intermittent exotropia?.

What causes intermittent exotropia?

First, blocking one eye and destroying the fusion will make exotropia appear askew. When fusing, the eye position is in the right position, and the stereo sense is very good. The perceptual state of the strabismus eye is inhibited by a wide range of hemiretina when the strabismus appears.

Second: patients usually show a preference for one eye, however, generally do not say right eye exotropia or left eye exotropia. Because if you block the dominant eye, you can change the strabismus eye and induce the strabismus of the dominant eye.

Third: older children or adult onset of exotropia, oblique when you can feel diplopia. Exotropia is easily exposed when patients are tired, dazed or sick. Over time, in a few months to a few years, about 80% of intermittent exotropia patients will have poorer fusion control, and exotropia will gradually increase. In adult patients, the degree of strabismus can become very large.

matters needing attention

So when the head of the family finds that the child sometimes strabismus and sometimes does not strabismus, they should pay attention to it. They should take the child to the hospital to correct the eye position before the child's fusion function disappears, otherwise it will affect the normal development of the child's fusion function and three-dimensional function.
