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 ...

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 ...

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 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 ...

Figure 1: Co-expression of melanopsin and Brn3b defines a specific set of ipRGCs. Figure 2: Genetic ablation of Brn3b-positive ipRGCs does not impair targeting to the SCN. Here we show that, although ...

A new study 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 sensory processing plays an important ...

NPi-200 (Neuroptics) is a handheld automated pupillometer that includes a camera and a colour touch screen. It provides precise, accurate and objective measurements of pupil size and pupillary light ...

WEST LAFAYETTE, Ind. – Evaluating concussion patients for recovery and measuring compounding injuries can be done as simply as recording a video with a smartphone. Reflex, a smartphone application ...

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 ...

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 ...
