New eye scan may help diagnose autism early in children: Study

Melbourne on Feb 23 Researchers have developed a new eye scan that they claim could help identify autism in children years earlier than currently possible, an advance that may lead to better ways of diagnosing the developmental disorder.
According to the study, published in the Journal of Autism and Developmental Disorders, the non-invasive eye scan utilises a hand-held device to find a pattern of subtle electrical signals in the retina that are different in children on the autism spectrum.
The retina is an extension of the brain, made of neural tissue and connected to the brain by the optic nerve, so it was an ideal place to look," said Paul Constable, a co-author of the study from Flinders University.
Very early diagnosis means not only can children receive important interventions, but families are empowered to get the necessary supports in place, come to terms with the diagnosis, and make informed decisions," Constable said.
They said early detection in firstborn children may give parents the opportunity to decide if they want to have more kids, with previous studies indicating an increased likelihood siblings of autistic children are more likely to develop the disorder.
