You may have problems with balance and dizziness which can go worse if you are tired or stressed. The balance organs which are present in the inner part of the ear are connected with eyes so eye movements are required to be observed with each slight movement of head position, which makes the diagnosis of the vertigo proper in the patients. It is considered the new standard for testing inner ear functions over ENG as the infrared cameras are positioned to directly track the eye movements instead of measuring mastoid muscles around the eyes which were done with the use of electrodes before.
To determine inner ear disease are affected with dizziness or not, VNG test is used. VNG tests are responsible for measuring the visual responses with use of Video Frenzel Goggles while ENG tests use electrodes. The issues of dizziness or balance disorder can be felt if the cause behind is inner ear and this test is used to determine that. Hi-tech Video Frenzel System Goggles are used in different positions when the person is looking in different directions with infrared cameras. These Video Frenzel Goggles are used to record eye movements. The Video Head Impulse Test consists of visual tasks, sitting and laying in different positions, and caloric.
The ears are then passed with cool air and warm air to determine the functioning of the inner ear in caloric testing. Infrared goggles are used for the eyes to record eye movements.
