Abstract Specific learning disorder (SLD) is a neurodevelopmental characterized by difficulties in reading, writing and math skills. Saccadic eye movements play critical role fluent reading visual scanning. 40 children with dyslexia healthy controls were included this study according to DSM-5 criteria, since have fluency disorders saccadic are necessary for reading. Psychiatric evaluations structured clinical interviews conducted an experienced child adolescent psychiatrist. (saccadic velocity, accuracy latency) recorded using videonystagmography (VNG) system compared between the two groups. Results showed that exhibited significantly lower velocity (307.5°/s vs. 453.5°/s, p < 0.001) (71.5% 98.5%, longer latency (260.0 ms 131.5 ms, 0.001). Optokinetic responses right less SLD group (p = 0.028), whereas no significant difference was observed left 0.067). These findings suggest oculomotor dysfunction independent of act This may contribute impaired information processing, assessment be useful tool development etiologic diagnosis interventions.
