Here are a few clips taken over a year showing the how optometric vision therapy successfully cured a 20^ exotropia in a 12 year old . He had been told there was nothing to do at his age to improve his lazy eye or his lack of stereovision. His exotropia was of the divergent excess type. That is why surgery was not recommended. After 2 months,when he had a 12^exotropia at far, he enjoyed much better fusion at near and could appreciate the Stereofly stereopsis test. The improvement after 7 years is staggering and shows how their are algorithms at work in the brain which constantly tries to create the best possible visual situation for itself.
It explains what I've seen over the last 30 years (and 15000 patients) in as much as the vast majority of patients who complete their treatment program come back a year or two later with a visual system operating with even greater efficiency than the day they completed their treatment.
