Slower Pupil Responses Seen In Autistic Children

Researchers at the University of Missouri, using a newly-developed pupillary response test, have shown that children with autism have pupils that respond slower to light.   The researchers used an infrared device to measure pupil responses to a 100 millisecond flash of light.

The researchers, according to the December issue of the Review of Optometry, have received a grant from the National Institute of Health for further research.  If the findings could be validated using larger studies, it could mark a method of detecting autism earlier.   And an earlier diagnosis would better prepare parents and children for developmental treatments.
