Measuring optic nerve sheath diameter in hypertensive emergencies
Part of Brain & nervous system, Eyes & vision, Heart & circulation clinical trials.
This study looks at whether the size of the optic nerve sheath (the lining around the nerve behind your eye) can help doctors understand how serious a hypertensive emergency is. By measuring this in the emergency department, doctors hope to better identify patients who need more intensive treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You are coming to the emergency department with very high blood pressure (top number over 200 or bottom number over 120).
- You should not have eye conditions like glaucoma, retinal artery/vein blockages, or other issues that prevent doctors from seeing the back of your eyes.
- Your high blood pressure should not be primarily caused by a recent stroke.

This study checks if ultrasound measurements of the optic nerve sheath can help guide treatment for brain swelling after a head injury. It aims to make treatments safer and more effective for patients with traumatic brain injury.
This study looks at how a certain way of delivering blood to the brain during surgery on the upper aorta affects eye pressure, which may indicate brain swelling. It may help doctors improve safety during these surgeries.
This study looks at how blood flows in the optic nerve (the nerve that carries visual information from the eye to the brain) using advanced imaging. It aims to better understand different optic nerve conditions, which may help improve diagnosis and treatment in the future.
This study measures the size of the optic nerve (the nerve that sends visual information from the eye to the brain) using ultrasound in healthcare workers. It aims to see how different levels of training affect the measurement accuracy.
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.
This study uses eye scans to see if changes in the retina can help doctors measure pressure inside the skull. It may help find a safer way to check for high pressure in the brain without needing a needle in the back.
