Abstract<\/strong><\/p>\n

Background<\/strong><\/p>\n

There are claims that ocular accommodation differs in children with attention deficit hyperactivity disorder (ADHD) compared to typically developing children. We examined whether the accommodation response in ADHD children is influenced by changing the stimulus to accommodation in an attempt modify the level of attentional engagement or by medication for the condition.<\/p>\n

Methods<\/strong><\/p>\n

We measured the accommodative response and pupil diameter using a binocular, open-field autorefractor in non-medicated and medicated children with ADHD (n<\/i>\u2009=\u200922, mean age\u2009=\u200910.1\u2009\u00b1\u20092.4\u00a0years;\u00a0n<\/i>\u2009=\u200919; mean age\u2009=\u200911.0\u2009\u00b1\u20093.8\u00a0years; respectively) and in an age-matched control group (n<\/i>\u2009=\u200922; mean age\u2009=\u200910.6\u2009\u00b1\u20091.9\u00a0years) while participants were asked to maintain focus on (i) a high-contrast Maltese cross, (ii) a frame of a cartoon movie (picture) and (iii) a cartoon movie chosen by the participant. Each stimulus was viewed for 180\u00a0s from a distance of 25\u00a0cm, and the order of presentation was randomised.<\/p>\n

Results<\/strong><\/p>\n

Greater lags of accommodation were present in the non-medicated ADHD in comparison to controls (p<\/i>\u2009=\u20090.023, lags of 1.10\u2009\u00b1\u20090.56\u00a0D and 0.72\u2009\u00b1\u20090.57\u00a0D, respectively). No statistically significant difference in the mean accommodative lag was observed between medicated ADHD children (lag of 1.00\u2009\u00b1\u20090.44D) and controls (p<\/i>\u2009=\u20090.104) or between medicated and non-medicated children with ADHD (p<\/i>\u2009=\u20090.504). The visual stimulus did not influence the lag of accommodation (p<\/i>\u2009=\u20090.491), and there were no significant group-by-stimulus interactions (p<\/i>\u2009=\u20090.935). The variability of accommodation differed depending on the visual stimulus, with higher variability for the picture condition compared to the cartoon-movie (p<\/i>\u2009<\u20090.001) and the Maltese cross (p<\/i>\u2009=\u20090.006). In addition, the variability yielded statistically significant difference for the main effect of time-on-task (p<\/i>\u2009=\u20090.027), exhibiting a higher variability over time. However, no group differences in accommodation variability were observed (p<\/i>\u2009=\u20090.935).<\/p>\n

Conclusions<\/strong><\/p>\n

Children with ADHD have a reduced accommodative response, which is not influenced by the stimulus to accommodation. There is no marked effect of medication for ADHD on accommodation accuracy.<\/p>\n","protected":false},"excerpt":{"rendered":"
