The purpose of this study is to find help for intermittent exotropia (eyes that drift) by using overminus glasses (glasses that are intentionally stronger).
This research is being done with children who have a condition called intermittent exotropia. Intermittent exotropia is the medical term used when the eyes turn out some of the time and are straight at other times. Intermittent exotropia is one of the most common types of eye misalignment in children.
Intermittent exotropia is often treated with surgery on the eye muscles to make the eyes straight again. There are different ways to do this surgery to straighten the eyes. One way is to operate on two muscles on one eye. Another way is to operate on one muscle on each eye. Both ways of doing the surgery work well but we do not know if one way is better than the other. This is the reason why the study is being done.
