Immaturity of the oculomotor saccade and vergence interaction in dyslexic children: evidence from a reading and visual search study.

Studies comparing binocular eye movements during reading and visual search in dyslexic children are, at our knowledge, inexistent. In the present study we examined ocular motor characteristics in dyslexic children versus two groups of non dyslexic children with chronological/reading age-matched. Bin...
