Recruiting studies
- NCT07539831Recruiting
Menstrual cycle effects during minimally invasive gynecology surgery
This study examines how the menstrual cycle may affect pressure in the optic nerve (the nerve connected to your eye) during laparoscopic gynecologic surgery. Researchers want to understand if the timing of surgery within your cycle matters for eye and brain safety.
KonyaAges 18–45 - NCT04600570Recruiting
Ultrasound measurement of the eye nerve in adults
This study uses an ultrasound scan to measure the space around the optic nerve in healthy adults. It helps researchers better understand normal ultrasound measurements for comparison in future eye or brain-related conditions.
TaipeiAges 20 years+ - NCT06491693Recruiting
Can eye nerve test predict brain complications after carotid surgery?
This trial checks if measuring the nerve sheath in your eye can help doctors predict brain-related problems after carotid artery surgery. It aims to improve safety during the procedure.
IstanbulAges 50–80 - NCT07262125Enrolling by invitation
Carbon dioxide pressure and eye nerve sheath in kidney surgery
This study looks at how the carbon dioxide gas used during keyhole kidney cancer surgery affects the pressure behind your eye. The goal is to see if changes in gas pressure influence the nerve sheath that surrounds the optic nerve.
Istanbul, AtaşehirAges 31–69 - NCT07666984RecruitingPhase 4
Effect of two reversal drugs on optic nerve sheath size
This trial compares two medications given after surgery to see how they affect the size of the sheath around your optic nerve, which can show changes in brain pressure. It helps doctors understand which medication might be safer for your eyes and brain.
AdanaAges 18–65 - NCT04510363Recruiting
Ultrasound checks after cardiac arrest to predict recovery
This study uses ultrasound pictures of the eye and blood vessels after a non-traumatic cardiac arrest to see if early findings can predict how well patients recover. It may help doctors recognize which patients are more likely to improve using simple bedside tests.
TaipeiAges 20 years+ - NCT06254534Recruiting
Medications for eye pressure during breathing tube placement
This study tests how four different medications affect pressure inside the skull during the placement of a breathing tube for surgery. The medications are lidocaine, dexmedetomidine, esmolol, and magnesium—all commonly used to calm the body's response to intubation.
IstanbulAges 18–80 - NCT06464419Recruiting
Effect of surgery position on eye nerve sheath size
This study is for people having kidney stone surgery. It looks at how the position you are in during surgery affects the nerve sheath around your eye, which may help doctors monitor pressure in the brain.
AnkaraAges 18–65 - NCT06979700Recruiting
Early wake-up predictors after cardiac arrest
This study looks at patients who had a cardiac arrest outside the hospital and are still unconscious after their heartbeat returns. The goal is to find early signs that predict when someone will wake up.
Aarhus NAges 18 years+ - NCT07332234Recruiting
Optic nerve ultrasound for brain inflammation and pressure
This study uses a quick ultrasound of the optic nerve to help doctors detect swelling or pressure in the brain. It may help people with suspected meningitis, encephalitis, stroke, or brain tumors decide on the best treatment earlier.
Bucharest, BucharestAges 18–60 - NCT07452367Recruiting
Bentall surgery study: optic nerve and thinking ability
This study checks if swelling of the optic nerve sheath during heart surgery with a bypass machine is linked to changes in thinking ability after the operation. It may help understand why some people have mental fogginess after surgery.
Bursa, YıldırımAges 18–80 - NCT07464938Recruiting
Predicting brain recovery after cardiac arrest
This study is testing new tools and markers to better predict recovery after cardiac arrest when brain injury may occur. It involves adults who had a cardiac arrest outside the hospital and are being treated at Saint-Luc hospital.
BrusselsAges 18 years+ - NCT07491198Recruiting
Head-Down Position and Eye Pressure in Prostate Surgery
This study looks at how the steep head-down position (Trendelenburg) and gas inflation during robot-assisted prostate surgery affect the sheath around the optic nerve. It aims to understand eye pressure changes to improve safety.

Common questions
- Are there clinical trials for optic nerve sheath diameter?
- Yes. Clin2 currently lists 13 recruiting optic nerve sheath diameter studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a optic nerve sheath diameter trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a optic nerve sheath diameter trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
