Mysuru: Columbia Asia Hospital in city has launched Videonystagmography (VNG) Test for Vestibular Disorder at its premises recently. This Test is invaluable in predicting early stroke, even before it is picked up on MRI and is also useful in assessing the response to treatment of various balance disorder.
VNG testing is a series of tests designed to document a person’s ability to follow visual objects with their eyes and how well the eyes respond to information from the vestibular system. In the testing, a camera attached to a pair of goggles worn by the patient records eye movement as the patient looks back and forth between designated points, tracks moving lights and moves the head and body into different positions.
