In the past, pupillary light reflex has been used to assess serious brain injuries. And in 2018 a team from the University of Washington presented a smartphone app designed to screen for ...

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 ...

Autism in children can be easily detected using a simple eye test. Pupillary light reflex could be the best way to screen autism spectrum disorder (ASD) in young children.

Using the latency component of the pupillary light reflex, they were able to distinguish subjects with or without autism with 89.6% success.

Pupil reflexes were measured in response to light in each eye for four seconds for four trials. The pupils of children in the group with autism took markedly longer to constrict in 70 per cent of ...

Lead author and doctoral course student, Yuta Suzuki explains "The pupillary light reflex, in which the pupil constricts and dilates, follows a very concise route in neural processing.

This is known as the pupillary reflex. While certain drugs, like alcohol and opioids, can cause our pupils to constrict, others, like LSD, magic mushrooms, and cocaine, can cause them to dilate.

A light flashes to initiate a response from the pupil. Reflex is a Class I 510 (k) exempt regulated medical device, according to the U.S. Food and Drug Administration.
