There are many different behavioral characteristics that involve the visual system. Poor eye contact, staring at lights or spinning objects, looking askance, side viewing and general difficulties attending are often symptoms of visual dysfunction. Thus, any child or individual with a diagnosis of autism, PDD, learning disability, speech-language delay, sensory integration dysfunction, non-verbal learning disability or with psychological problems should most certainly undergo a thorough eye examination. The earlier children with any behavioral or social disorder undergo a visual examination and begin visual intervention, the faster the improvement. The longer lasting the gains and overall chances for success.
