Electro/ Videonystagmography (ENG/VNG)

ENG/VNG testing is used to determine if a vestibular (inner ear) disorder is causing problems with balance or dizziness. The test is performed by measuring eye movements through the use of electrodes or goggles which contain a video camera. This eye movement is called nystagmus and occurs during certain kinds of visual and vestibular stimulation. Nystagmus can help to distinguish between a peripheral vestibular disorder and one that is located within the central nervous system.

ENG/VNG Consists of Three Sections:

  • Oculomotor testing, which involves looking at or tracking individual lights.
  • Positional testing, which involves lying on a table in different positions.
  • Caloric testing, which involves irrigation of each ear with warm and cool water.
