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 ...

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 ...

Automated pupillometry has emerged as a transformative tool in neurological critical care by providing an objective, quantitative assessment of the pupillary light reflex. Traditionally, the ...

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.

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 ...

The creation of a bionic eye that mimics the widening and shrinking of the pupil may bring us one step closer towards helping people with certain visual impairments. Light enters the eye via the pupil ...
