This new research looks at a behavior in the eye called pupillary light reflex. This is the simple reflex our pupils make in response to surrounding light levels. In the past, pupillary light ...

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 ...

However, in patients with heart failure, autonomic dysfunctions inhibit the pupil light reflex (PLR), aka pupillary reflex, from constricting or dilating pupil size appropriately in response to ...

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.

This is called consensual light reflex, and the test is commonly known as the Marcus Gunn test, or the “swinging flashlight test.” Pupils react to light being shone into them in this way ...

"To establish and validate our technology, we focused on the pupillary light reflex (PLR) when the pupil constricts in response to a sudden flash of light, and then dilates back to normal.

Pupil Reflex Test In a dimly lit room, stand in front of a mirror with a flashlight held away from your face. Look at your right eye while you shine the light directly into your left pupil. Your right ...

“As we think of kids with autism, as all of those things are disrupted during development, the pupillary light reflex is a good noninvasive measure to look at whether this part of the brain is ...

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 ...

SPOKANE, Wash.—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 ...

Researchers have now discovered that when light impinges on the photoreceptor-free blind spot alone the pupillary reflex does not occur, but the pupillary reflex is enhanced in response to bright ...
