ENG Test
Electronystagmography (ENG)
Electronystagmography (ENG) is a test that shows the movement of your eyes in order to determine how well two cranial nerves within your brain are functioning. The two nerves are the acoustic (or vestibulocochlear) nerve and the oculomotor nerve. The acoustic nerve connects the brain and the inner ear and controls hearing and balance. The oculomotor nerve connects the brain to the muscles of your eyes.
VNG Test
Video Nystamography basic test to find out cause of vertigo & dizziness
A VNG test stands for Videonystagmography and an ENG test stands for Electronystagmography.
Both of these test the vestibular system (balance system) of the inner ear to determine if your dizziness/loss of balance is caused by an inner ear abnormality.
When undergoing the VNG test, you are wearing a pair of goggles over your eyes used to monitor and record eye movement. During the ENG test, instead if wearing goggles, you have sticker electrodes placed around your eyes and forehead to record eye movements.
