vision therapyA clinical approach for correcting and ameliorating the effects of eye movement disorders, non-strabismic binocular dysfunctions, focusing disorders, strabismus, amblyopia, nystagmus and certain visual perceptual (information processing) disorders.
A vision-enhancing method developed in the 1920s by an American optometrist, AM Skeffington. Vision therapy uses eye exercises and other techniques to retrain the eyes to function as a unit, and co-ordinate the brain’s processing of visual information needed for binocular vision; it is allegedly useful for lazy eye (amblyopia), crossed eyes (strabismus), problems of focusing (vergence and accommodation), oculomotor defects, learning disabilities, athletic performance and traumatic brain injury. While vision therapy may be of use in developing stereoscopic skills and improving visual field remnants after brain damage, there is no clear scientific evidence supporting the use of eye exercises to improve vision.
Methods aimed at improving visual abilities, e.g. visual perception, spatial localization, heterophoria, hand/eye coordination, etc. to achieve optimal visual performance and comfort. These techniques represent an enlargement of the practice of orthoptics. Syn. vision therapy.
