Vision in Children and Adolescents with Autistic Spectrum Disorder: Evidence for Reduced Convergence
Milne, Elizabeth; Griffiths, Helen; Buckley, David; Scope, Alison
Journal of Autism and Developmental Disorders, v39 n7 p965-975 Jul 2009
Evidence of atypical perception in individuals with ASD is mainly based on self report, parental questionnaires or psychophysical/cognitive paradigms. There have been relatively few attempts to establish whether binocular vision is enhanced, intact or abnormal in those with ASD. To address this, we screened visual function in 51 individuals with autistic spectrum disorder and 44 typically developing individuals by measuring visual acuity, stereoacuity, convergence, divergence, ocular motility, incidence of strabismus and integrity of the optokinetic response. The data suggest that many aspects of vision, including visual acuity, are unaffected in ASD, but that convergence is an aspect of visual function that merits further research in those with ASD.
