FDA recently issued a warning to the public not to use tools such as smartphone- or tablet-based apps that claim to help assess, diagnose or manage head injury. NORA urges consumers to follow the FDA’s warning not to use unapproved or uncleared medical devices to help assess or diagnose a concussion on their own and we strongly urge consumers who may notice any changes in their vision following a concussion or some other head trauma not to ignore them and immediately contact their eye care professional to determine the cause of the vision change.
