A simple bedside eye test may help predict recovery of consciousness in patients with severe brain injuries, according to new ...

Retinal illumination primarily determines pupil size, yet extra-retinal factors like subjective brightness also influence pupillary responses. Previous works reported that in healthy individuals, ...

This study assessed the pupil responses in the sensory integration of various directional optic flows during the perception of gravitational vertical. A total of 30 healthy participants were enrolled ...

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 study, led by researchers from UNSW Sydney and published in eLife, found that the pupils of people with aphantasia did not respond when asked to imagine dark and light objects, while those without ...

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.

New findings from researchers at UCLA Health suggest that measuring changes in how pupils react to light could help predict recovery from depression and personalize transcranial magnetic stimulation ...

The horizontal axis represents the time elapsed following the presentation of the image, while the vertical axis denotes the degree of change in pupil diameter relative to the image presentation. A ...

Picture this, if you will: Aphantasia can be detected with an eye-opening look into our pupils. To first gauge the pupillary reflex of non-aphantasic people, the researchers sought 42 study ...

PORTLAND, Ore. (KOIN) — A new study published by researchers at Washington State University suggests testing how the eyes’ pupils change in response to light could potentially be used to screen for ...
