Ultrasound measurement of the eye nerve in adults

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 a special ultrasound on the eye to measure the optic nerve sheath, which can help detect increased pressure in the brain without needing an invasive test. It aims to provide a rapid, bedside method to identify patients who need urgent treatment.

This study collects ultrasound and nerve test data from healthy adults to establish normal values. It may help improve diagnosis of nerve conditions in the future.

This study uses an imaging scan called optical coherence tomography (a non-painful light scan) during surgery to map what “normal” eye tissue looks like. It may help improve how eye specialists assess eyes in the future.

This study uses a safe ultrasound test that looks at the nerve at the back of your eye to check for pressure inside the skull after a head injury. It may help doctors monitor you more easily without more invasive procedures.
