Pupil changes during vagus nerve stimulation during ear surgery
Part of Brain & nervous system, Ear, nose & throat clinical trials.
This study looks at how your pupils (the black center of the eye) respond while a vagus nerve device is turned on during surgery for either a cochlear implant or a vagus nerve stimulator. It aims to better understand the eye/nerve effects of this stimulation, which may improve how such procedures are done safely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are age 18 or older and can agree to join the study
- You are scheduled for cochlear implant surgery or an implantable vagus nerve stimulator surgery
- You do not have a past ear surgery that would count as prior ear surgery for the study (and no prior cochlear implant)
- You are not pregnant or breastfeeding
- You do not have certain health issues that affect the vagus nerve or safety of stimulation, like heart rhythm problems or lung disease

This study records how the hearing nerve responds to speech sounds during planned brain surgery. It aims to understand hearing loss better and may help improve future treatments.
This trial tests if stimulating a nerve in your ear (vagus nerve) before and after noncardiac surgery can improve your recovery. It's for adults aged 18 to 84 having planned or time-sensitive surgery lasting at least 2 hours.
This study tests whether gentle electrical stimulation of a nerve in the ear can help older adults sleep better after surgery. It's for people 65 and older having planned surgeries that don't involve the brain.
This study tests a new way to stimulate your hearing nerve during ear surgery while you are awake. It might help doctors better understand hearing loss and improve future treatments.
This trial tests if a gentle nerve stimulation device on the ear can help prevent confusion (delirium) and improve mood after heart surgery. It is for people having planned heart operations like bypass or valve repair.
This trial tests a safe, noninvasive way to stimulate a nerve in your ear (the vagus nerve) to see how it affects your heart and blood vessels. Eligible volunteers must be healthy adults between 18 and 45, not taking heart or mood medications.
