Pupil response study in healthy adults

This study looks at how healthy adults pay attention to, recognize, and look at images. It may help scientists understand normal vision, which can guide future treatments for vision problems.

This study looks at how different pain treatments affect a child’s pupils (the dark center of the eye). It may help doctors better understand which pain medicines are working and how to measure pain treatment effects more accurately.

This study checks how well a device can measure how your pupils respond to colored light. It may help improve eye testing, especially when monitoring certain vision and nerve conditions.

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.

This study uses detailed eye measurements to compare findings in people with pseudotumor cerebri and in healthy eyes. It may help researchers understand how pupil responses and eye structure change with pseudotumor cerebri.

This study tracks how your pupils react to light over time while you are in the ICU, to see if those changes relate to how you recover. It is a simple, non-invasive way to help doctors better predict outcomes for critically ill patients.
