Ultrasound measurement of the eye nerve in adults

This trial is studying a method for measuring the optic nerve size using ultrasound. It focuses on healthcare trainees and experienced ICU nurses to see how well different skill levels perform the measurement.

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 an OCT (a special camera that scans the back of your eye) to measure the thickness of nerve layers in people with nearsightedness (myopia) or farsightedness (hyperopia). It helps doctors understand how different prescriptions affect eye structures.

This study uses ultrasound to measure eye structures, like the optic nerve, to see if they can help detect increased pressure in the brain. It compares these measurements with CT or MRI scans to see how accurate the ultrasound is.

This study uses ultrasound to measure the optic nerve in people with relapsing-remitting multiple sclerosis who have never had optic neuritis. It aims to see if this measurement can predict when the disease might change from one form to another.

This study uses a simple eye ultrasound to measure eye structures during gallbladder surgery. It aims to see if these measurements can help monitor pressure inside the head during the procedure.
