| Summary: | This article presents an overview of the eye and visual training research in the treatment of dyslexia and associated learning disabilities. The cited references utilize operational definitions which vary considerably from reading retardation of any etiology to a more narrowly defined concept of dyslexia as a specific, incurable entity due to a specific brain lesion. The role of visual function in learning disability may run the gamut from interferences in the more mechanical aspects of vision such as binocular fusion, accommodation, and eye aiming, which will limit efficiency at the reading activity, to a failure of development of adequate visual perception abilities which will make it impossible to develop fundamental word recognition skills. Incurable reading disorders represent a very small portion of all reading or learning problems encountered. Interestingly, their data indicate that dyslexic children show a much higher incidence of subjective ocular complaints during near work than their controls, and they also state that there is a preponderance of latent strabismus in the wordblind group as compared to the controls.
