In medicine, the pupillary reflex or pupillary light reflex, is the reduction of pupil size in response to light. It is a normal response and dependent on the function of the optic nerves and ...

Pupillometry, the precise measurement of pupil size and dynamics, has emerged as a valuable tool in evaluating both autonomic nervous system integrity and central neural function. In particular, ...

Researchers are reporting progress in understanding whether a second light-sensing pathway in mammals indeed contributes to the detection of ambient light for controlling body functions. January 10, ...

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 ...

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 ...

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.

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 ...

The eye’s light-sensing retina taps different circuits depending on whether it is generating image-forming vision or carrying out a non-vision function such as regulating pupil size or sleep/wake ...

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 ...

An artificial vision sensor inspired by the human pupil adapts automatically to light, maintaining clear perception from darkness to glare and sharply improving recognition accuracy in machine ...
