Eye test may spot brain fog after heart surgery
NCT ID NCT07249047
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether measuring the optic nerve sheath (the covering of the nerve at the back of the eye) using ultrasound can help predict delirium—sudden confusion or agitation—after heart surgery. Researchers will monitor 300 adults before and after their operation. The goal is to see if a simple, non-invasive eye scan can catch early signs of this common complication.
