The human retina contains some 100 million photoreceptor cells. When these are stimulated with light, they communicate that information to the brain and we perceive light. Researchers have now ...

A new study showed that NeurOptics Pupillometers reliably measure the presence and quality of the pupillary light reflex after cardiac arrest and during resuscitation, producing readings that ...

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 ...

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 ...

A new study published in Nature Communications shows that infants who are later diagnosed with autism react more strongly to sudden changes in light. This finding provides support for the view that ...

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 ...

Objective Pupillary light reflex (PLR) metrics are enhanced in adolescents with concussion. It is not known if these PLR metrics in concussed adolescents return back to the normal range at recovery.

Introduction Changes to the pupillary light reflex (PLR) have been demonstrated in traumatic brain injury and in adolescents with a history of concussion. Assessment of changes to the PLR following ...

A new study shows that infants who are later diagnosed with autism react more strongly to sudden changes in light. This finding provides support for the view that sensory processing plays an important ...
