To assess binocular control in children with dyslexia. Cross-sectional study with 26 children who were submitted to a set of ophthalmologic and visual tests. In the dyslexic children less eye movement control in voluntary convergence and unstable binocular fixation was observed. The results support the hypothesis that developmental dyslexia might present deficits which involve the magnocellular pathway and a part of the posterior cortical attentional network.71837-40
