Intermittent Exotropia is a form of strabismus (eye misalignment) in which one or both of the eyes turn outward. It may occur from time to time.
My five year old has this eye condition. We have been sending her for tests and treatments for a few years now.
Her vision is perfect but one of her eyes will drift to the side now and then. It usually happens more when she is tired. It also happens when we tell her something and she has to think about it. And if she sees something out into the distance, only one eye will focus on the subject.
Last year we spent a frustrating year of taking her regularly to visual therapy and doing daily eye exercises.
I did look into other forms of treating it, such as surgery, but this would have never worked as her eyes only drift now and then, not permanently. Glasses would also not have worked. We tried using an eye patch, but this then made the other eye lazy.
This year we found out about an optometrist who had special equipment used to treat eye conditions in children. Namely, computer games. They exercise the brain and not just the eye muscles.

I'm not sure how many more times we must take her, but if it's helping I'm happy.
