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 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 ...

WEST LAFAYETTE, Ind. – Capturing objective data in about five seconds that can aid concussion diagnoses through an iPhone, the Reflex PLR Analyzer, an industry-disruptive diagnostic tool for traumatic ...

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 ...

University of Tokyo researchers have found that the light reflex of the pupil is modulated by light stimulation inside the blind spot in normal human observers, even though that light is not perceived ...

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 ...

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 ...

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 ...

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 ...
