What does Electronystagmography test for?
Electronystagmography (ENG or electrooculography) is used to evaluate people with vertigo (a false sense of spinning or motion that can cause dizziness) and certain other disorders that affect hearing and vision. Electrodes are placed at locations above and below the eye to record electrical activity.
What does a VNG test diagnose?
VNG testing is used to determine if a vestibular (inner ear) disease may be causing dizziness, room spinning sensation or balance problem, and is one of the only tests available today that can decipher between a unilateral (one ear) and bilateral (both ears) vestibular loss.
What does the caloric test measure?
Caloric stimulation is a test that uses differences in temperature to diagnose damage to the acoustic nerve. This is the nerve that is involved in hearing and balance. The test also checks for damage to the brain stem.
What is the meaning of VNG?
Videonystagmography (VNG) is a test that measures a type of involuntary eye movement called nystagmus. These movements can be slow or fast, steady or jerky. Nystagmus causes your eyes to move from side to side or up and down, or both.
What type of doctor does an ENG test?

How do they check for inner ear problems?
Tests that assess function of the inner ear include:
- Videonystagmography (VNG). This test evaluates balance function by assessing eye movement.
- Rotary-chair testing.
- Vestibular evoked myogenic potentials (VEMP) testing.
- Posturography.
- Video head impulse test (vHIT).
- Electrocochleography (ECoG).

Is a VNG test uncomfortable?
VNG testing is non-invasive, and only minor discomfort is felt by the patients during testing as a result of wearing goggles. Appointments usually last about 1.5 hours, and testing is covered by all insurances.
What should you not do before a VNG test?
Avoid solid foods or milk for 2 to 4 hours before the test. Please do not have any coffee, tea, cola, or caffeine after midnight on the day of the test. You shouldn’t take aspirin or medication containing aspirin for two days before the test.
Will brain MRI show ear problems?
Eye and ear disorders. MRI of the head can help in investigating the inner​ ear structures and optic nerves to detect vestibular disorders and inflamed optic nerves, among others.
