Ocular movements in patients with dyslexia

Purpose: to evaluate the association between dyslexia and eye movement. Methods: The sample was composed of 11 children with dyslexia and 11 healthy subjects between the ages of 8-13 years. All partecipants underwent orthoptic evaluation, ophthalmological examinations, eye movement analysis, stability analysis on fixating a still target, tracking saccades, analysis of fixation pauses, speed reading and regressions through the reading of a text. Results: Stability analysis on fixating a still target displayed an important difference between the two groups with a higher rate of fixation loss in patients with dyslexia. Also reading parameters analysis showed a significant difference between the two groups. Conclusion: This study confirm that alternation of eye movements in children with dyslexia depend on failing of processing linguistic material and this assessment can be helpful to detect this disfunction for a earlier intervention in young children.
