Intermittent exotropia is difficult to treat. The mainstay of treatment involves surgery, and in one long-term study authors found that as many as 60% of IXT required at least one re-operation.Patching of the non-dominant eye has also been tested in a large, multi-center randomized control trial and was not found to have a large benefit. More non-surgical treatment modalities are critical to improve the care in this condition.
