Abstract

Attention deficit hyperactivity disorder is one of the most frequently diagnosed Childhood Psychiatric disorders, with worldwide prevalence rates estimated at 5.3%. Behavioral manifestations of visual perceptual problems, particularly color perception have been associated with ADHD: collectively, the preceding findings indicate the need for further investigation of visual function and its regulation by the attentional process in ADHD. ADHD children have problems with selective attention (suppressed responses to irrelevant stimuli with responses to irrelevant stimuli and sustained attention to maintain concentration for a long time). In addition, their overall attention-concentration capacity is insufficient, resulting in low performance in tasks requiring a higher level of attention-concentration ability. Attention concentration ability is also related to visual function. Vision plays a very important role in everyday life as a sense of receiving and processing about 70% of information from outside. The prevalence of vision problems is 15.6% in children with ADHD, which is much higher than that (8.3) in normal children. Frequent vision problems in children with ADHD can lead to problems with the color classification of depth perception. The prevalence of ADHD in children with convergence insufficiency is about three times higher than the prevalence of ADHD in the general US population. In the study done by Cho., et al. For children with inattention type o ADHD, intermittent exotropia accounted for 12.2% and esotropia accounted for 2.0%. The incidence of strabismus was 18.3% in all subjects which was much higher than the general incidence. Therefore strabismus appears to be one of the major characteristics of visual function disorder in children with ADHD. Optometric vision therapy has been applied to the broad spectrum of visual and non-visual functions and disorders, such as convergence, reading, dyslexia, ADHD, sports performance, and concussion. Despite varied etiologies and treatment modalities associated with ADHD children, the primary obligation of the optometrist is to assess and manage visual function. Vision therapy has been introduced as a method for improving visual perception. This review will focus primarily on published data regarding ADHD, vision therapy, and convergence insufficiency.
