Is there anything else I need to know about a VNG?Another test called electronystagmography (ENG) measures the same type of eye movements as a VNG. It also uses ocular, positional, and caloric testing. But instead of using a camera to record eye movements, an ENG measures eye movements with electrodes placed on the skin around the eyes.While ENG testing is still being used, VNG testing is now more common. Unlike an ENG, a VNG can measure and record eye movements in real time. VNGs can also provide clearer pictures of eye movements.
