Patient Instructions for VNG/ENG Tests

Your doctor has determined a need for further testing and has scheduled you for Videonystagmography (VNG) testing on ______at ______AM/PM. If you need to reschedule or cancel the testing, please call our office at least 48 hours prior to your scheduled appointment. The VNG/ENG evaluations are a series of tests designed to give your physician information regarding the source of your dizziness/vertigo/imbalance. The tests require up to one hour of your time for completion. There are three main parts of the tests: 1. Tracking (following a light with your eyes); 2. Sitting and laying in different body positions and following a light with your eyes; and 3. “Irrigating” each ear with warm and cool air. Throughout the tests you will be wearing infrared goggles that will record your eye movements. Portions of the tests may induce a sensation of vertigo, but this effect is brief and temporary. There is no pain or needle sticks with these tests; however, we recommend you have someone drive you from your appointment in case you experience dizziness from the testing.
