This study focuses on developing a new portable noninvasive system to aid in the diagnosis of the vision disorders Multiple Sclerosis and Optic Neuritis. This device combines images and patterns using a Head Mounted Display, similar to a virtual reality headset. The system measures brain responses to these images using a form of electroencephalography (EEG), which will give us information about how the brain and eyes communicate and how this may be affected by a vision disorder.
- Healthy Volunteers (with normal vision or vision that can be corrected to 20/20 or better with glasses or contact lens) OR a diagnosis of Multiple Sclerosis and/or Optic Neuritis
A history of photophobia (sensitivity to light) or epilepsy
This study will be conducted in 1 session lasting 45-90 minutes. During the session, short questionnaires will be given before and after the device trials. A standard visual evoked potential (VEP) test (using an approved device) will be assessed along with the investigational VEP device. In both tests images and patterns will be displayed to participants, and brain signals will be measured by the devices.
Participants will be compensated with $25 for their time at the end of the study visit. Participation will contribute to the approval of this device which may help with timely and accurate diagnosis of Multiple Sclerosis and Optic Neuritis.
