Objects: This study aims to investigate the saccade/anti-saccade eye movement in children with attention deficit/hyperactivity disorder (ADHD).Methods: Twelve children (8.8 ± 0.8 years) diagnosed with ADHD (DSM-V) and 12 control (9.1 ± 0.3 years) were invited to participate in the experiment where the iView Hi-SPEED eyetracker, with the sample rate at 500 Hz Binocular, was employed. The visual guided saccade (VGS) task was used to collect saccade latency and accuracy values. The anti-saccade task was used to collect saccade latency and accuracy values as well as the percentage of direction errors (PDE).Results: Children with ADHD showed a significant difference in latency in the 7.5° target and imprecision in both targets (7.5° and 15°) during the VGS task. Moreover, the ADHD group exhibited shorter latency (15° target) and significantly higher numbers in the Percentage of Direction Errors in the anti-saccade tasks than the control group.Conclusions: The results suggest that children with ADHD have the following difficulties: precise oculomotor control, oculomotor response inhibition function and basic visual attention.

D001289	Attention Deficit Disorder with Hyperactivity	A behavior disorder originating in childhood in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity. Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood.
