Non-Invasive and Non-Contact Intracranial Pressure Waveform Recording Using Dynamic Video Ophthalmoscopy

Sponsor

University of Minnesota

Enrollment

90 participants

Start Date

Jan 31, 2023

Study Type

INTERVENTIONAL

Conditions

Intracranial Pressure Increase

Summary

This study will test the use of video ophthalmoscope to provide information about intracranial pressure without the use of invasive methods, anesthesia or contact with the eye.

Eligibility

Min Age: 4 Years

Plain Language Summary

Simplified for easier understanding

This study tests a non-invasive, contactless device that can measure intracranial pressure (the pressure inside the skull) by analyzing tiny pulsations in the eye. Normally, measuring brain pressure requires inserting a probe into the skull — this technology aims to do it without any surgery or contact with the patient. **You may be eligible if...** - You are able to sit still and focus your eyes on a target - You are a patient who already has an intracranial pressure probe inserted for clinical reasons (to validate the device's accuracy), OR you are a healthy volunteer **You may NOT be eligible if...** - You have a diagnosis of glaucoma (eye pressure condition), retinopathy (eye disease), or head tremor - You are unable to keep your eyes still and focused on a target Talk to your doctor to see if this trial is right for you.

This summary was AI-generated to explain the trial in plain language. It is not medical advice. Always discuss eligibility with your doctor before enrolling in a clinical trial.

Interventions

DEVICEVideo ophthalmoscope

Use of a custom video ophthalmoscope with either a CCD or CMOS camera lens. The healthy controls group (first 20 subjects) will provide data to help determine which lens might be best for measuring ICP patients (Groups A and B) in the second phase of the study.
