In medicine, the pupillary reflex or pupillary light reflex, is the reduction of pupil size in response to light. It is a normal response and dependent on the function of the optic nerves and ...

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 ...

Pupillometry, the precise measurement of pupil size and dynamics, has emerged as a valuable tool in evaluating both autonomic nervous system integrity and central neural function. In particular, ...

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 ...

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 ...

A new study published in Nature Communications 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 ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 115, No. 41 (October 9, 2018), pp. 10446-10451 (6 pages) Spatial attention enables us to focus visual processing ...

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 study conducted at ...

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 ...

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 a study ...

An artificial vision sensor inspired by the human pupil adapts automatically to light, maintaining clear perception from darkness to glare and sharply improving recognition accuracy in machine ...
