Eye ultrasound to predict confusion after heart surgery
Part of Brain & nervous system, Mental health clinical trials.
This study checks if a simple, painless eye ultrasound can help predict confusion (delirium) after heart surgery. It may help doctors identify patients at risk earlier and improve recovery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You are scheduled for heart surgery that uses a heart-lung machine.
- You are expected to stay in the cardiac intensive care unit for more than 48 hours after surgery.
- You can have an ultrasound of your eye through your closed eyelid.
- You do not have any serious eye injuries, recent eye surgery, or certain eye conditions that would make the test unsafe or inaccurate.
- You do not have severe facial trauma or an unstable neck that would prevent safe positioning for the test.
- You are not pregnant.
- You can speak and understand English.
- You are not enrolled in another conflicting research study.

This study uses special monitors to watch for confusion or disorientation (called delirium) after heart surgery. The goal is to detect it early and help you recover more smoothly.
This study uses brain monitoring and artificial intelligence to predict whether patients might experience confusion (delirium) after heart valve surgery. This could help doctors provide better care and prevent this common complication.
This study looks at whether ultrasound measurements of the neck and eyes, taken just before hip surgery, can help predict or prevent confusion (called delirium) that some older people experience after surgery. By monitoring these measurements, doctors hope to improve care during recovery.
This study checks if a simple ultrasound of the eye can help doctors quickly spot brain problems in the emergency room. It compares ultrasound results with CT or MRI scans to see if it's a reliable tool.
This study uses eye-tracking technology to see if it can predict post-operative delirium in older adults after surgery. You will have your eye movements measured before and after surgery to help identify early signs of delirium.
This study uses an ultrasound to measure the optic nerve sheath diameter (the space around the eye's nerve) before and after spinal anesthesia for cesarean section. The goal is to see if this measurement can predict post-dural puncture headache, a common side effect. If it works, it might help doctors prevent or treat these headaches sooner.
