BACKGROUND/AIMS The autonomic pupillary changes in type I and II diabetic patients without clinical evidence of diabetic autonomic neuropathy (DAN) were compared with age matched controls. The ...

For over a century, scientists believed that light, focus distance, and cognitive effort were the main forces behind changes in pupil size. But a new discovery adds breathing to that list. Researchers ...

For the first time, researchers have been able to observe how the pupils react during sleep over a period of several hours. A look under the eyelids showed them that more happens in the brain during ...

The pupil responds to light, which is essential for our vision and how we see our surroundings. Three known mechanisms change the pupil’s size: the amount of light, focus distance, and cognitive ...

Researchers at Karolinska Institutet found that breathing affects pupil size, with pupils being smallest during inhalation and largest during exhalation. This discovery, which suggests a ...

Researchers have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation ...
