Identifying the inner ear as the cause of dizziness in young children can be a challenge, but a few years ago an app was created that essentially replicates the subjective visual vertical (SVV) test. It mimics the more traditional SVV test in which a patient is asked to vertically position a glowing line while within a dark room. The ability to place the line accurately determines whether the dizziness arises from the brain or the inner ear, but having a dark and safe room available for such a test within a clinic can be pricey and cumbersome.
