Summary

Dyslexia is first described as a phonological deficit. Several studies report a neurovisual deficit in dyslexics. Some dyslexics have a visual deficit without phonological impairment, others have a pure phonological deficit, and still others have both types of deficits. From this observation the idea emerged to propose specific remediation protocols for people with visual impairments and to assess their effects on reading. At the theoretical level, if visual stimulation is able to improve reading performance, it is the demonstration of the existence of visual origin of dyslexia. At the clinical level, such a result not only opens the prospect of a different and more adapted rehabilitation for these types of dyslexia, but also the prospect, if the visual deficits are pre-existing to the learning of reading, to use them for early diagnosis and management.

Conditions

• Dyslexia

Interventions

Type	Name	Description
BEHAVIORAL	visual stimulation with I pad	At the beginning of the study, for baseline condition, children will do 4 tests (visuo-spatial perception test, visual attention span, visual research, phonology tests). In the first group of the study, the children will do visual research exercises on I pad 10 minutes per day during one month = remediation. They will also do 4 reading aloud tests, once a month, for 3 months. The remediation exercises will be realized during the first, second or third month.
BEHAVIORAL	visual stimulation with lamp	At the beginning of the study, for baseline condition, children will do the 4 tests like group 1. In the second group of the study, the children will do reading aloud tests, with lamp adjusted with different parameters = remediation (passive visual stimulation of a specific frequency believed to promote visual processing of written symbols).
