New Methods Of Diagnosis Of Stroke – Part 2 of 3
The other caveat is that the device is not yet approved in the United States for diagnosing stroke. The US Food and Drug Administration only recently gave it approval for use in assessing balance. It has been accessible in Europe for that purpose for about a year. The device – known as a video-oculography machine – is a modification of a “head impulse test,” which is used regularly for people with chronic dizziness and other inner ear-balance disorders.
And “There are 500 otolaryngologists and 4 million tottering patients in the US alone,” Newman-Toker said. “We otolaryngologists can’t see everybody and emergency extent physicians can’t easily be trained to develop expertise in eye movement interpretation. Now we have a device that can do it for them”.
The test is simple to perform: Wearing a pair of goggles hooked up to a webcam and close software, the patient is asked to focus on one spot on the wall while the doctor moves the patient’s head from side to side. “Normally, the balance system in the ears keeps our eyes balanced when our head is moving,” Newman-Toker explained.
