Pupil test in patients being checked for brain death

This trial tests a bedside brain-monitoring method (near-infrared light and EEG) in people who are unconscious after severe brain injury from cardiac arrest. The goal is to see whether it can help measure brain function during the first week after admission.

This study collects normal (baseline) results from a handheld eye pupil camera (a pupillometer) used during routine neuro–intensive care checks. It may help clinicians better interpret these eye measurements in future patients.

This study tracks how your pupils react to light while you're in the intensive care unit. Researchers believe these reactions may help predict how critically ill patients recover, and want to understand if monitoring them could improve care.

This study checks how children’s pupils react after they receive a medicine to lower brain pressure. It aims to see if a quick pupil test can help doctors know if the medicine is working.

This study looks at how pupil size and response relate to the severity of brain injury in newborns with HIE. It uses a special tool to measure the pupil, which may help doctors better understand the baby's condition.

This study aims to objectively measure how your pupils respond to light and how your eye muscles react using recording tests. It may help confirm the cause of light sensitivity (especially after a brain injury) and better track how it responds to care.
