To determine whether use of dichoptic movies for 8 weeks may be helpful in improving control alignment in children with intermittent exotropia (IXT), thus allowing IXT to be managed non-surgically
Intermittent exotropia (IXT) is the most common form of strabismus, characterized by an outward deviation of the eyes that is primarily manifest during distance fixation and can intermittently be controlled by fusional mechanisms. Less than 30% of children have good long-term outcomes following treatment for spontaneously manifest IXT with current non-surgical treatments (prism therapy, over-minus lenses, or vision therapy). The limited efficacy of current non-surgical treatments for IXT is thought to arise from underlying sensory deficits, particularly interocular suppression, which compromis…
