Pupil size in response to light could serve as a biomarker for concussion, according to a study published in Life. “A concussive injury to the brain is associated with changes in the PLR [pupillary ...

A simple eye test could one day diagnose autism, a study has suggested. The penlight reflex test, similar to that already performed by doctors, has shown promising results in preliminary tests by ...

Eye test can help identify autism in children Measuring how the pupils of the eyes change in response to light (pupillary light reflex) could be the best way to screen autism spectrum disorder (ASD) ...

May 28, 2010 (Philadelphia, Pennsylvania) — In an effort to find discrete phenotypic features that are consistently present in autistic populations, researchers at the University of Missouri Thompson ...

New research points to an easily measured eye response to light as a potentially useful way of diagnosing autism in very young children. Further testing is currently underway in a large cohort of ...

Medically reviewed by Johnstone M. Kim, MD Key Takeaways The pupil controls how much light enters the eye, allowing for clear ...

Measuring how the eyes' pupils change in response to light -- known as the pupillary light reflex -- could potentially be used to screen for autism in young children, according to a new study.

An abnormal red reflex finding most likely reflects an underlying ocular pathology in infants, but finding a normal red reflex during screening does not altogether exclude ocular disease. The American ...

An abnormal pupillary light reflex (PLR) is commonly detected in patients with glaucoma, and these differences can be used to distinguish glaucomatous eyes from unaffected eyes, according to the ...
