Electronystagmography is a diagnostic procedure that records spontaneous eye movements. The vestibular system can be tested with electronystagmography to determine the cause of dizziness, balance dysfunction, and vertigo. Electronystagmography is a technique for detecting even the tiniest movement of the eyes. Electronystagmography is performed by placing disc electrodes around the nose and connecting the electrical leads of the disc electrodes to an oscilloscope to measure spontaneous eye movement.
The movement of the eye is accurately recorded in electronystagmography testing because the cornea is electropositive and the retina is electronegative, so these electrodes accurately record the spontaneous movement of the eye. Videonystagmography, Rotary Chair Test, Computerized Dynamic Visual Acuity (DVA), Computerized Dynamic Posturography (CDP), Subjective Visual Vertical, and Vestibular Evoked Myogenic Potential are some of the diagnostic tests used in electronystagmography testing (VEMP). With the help of a video camera mounted inside the goggles that are worn during testing, a videonystagmography test (VNG test) records eye movement in a dark and light room.
Market Drivers and Restraints for Electronystagmography Testing
The market for electronystagmography testing is expected to grow in response to the rising number of inner ear disorders that cause vertigo. Additionally, rising healthcare spending, improved infrastructure, and reimbursement options are expected to be key drivers of the electronystagmography testing market over the forecast period.
However, the lack of awareness about related disorders in developing countries, the high cost of tests and devices, and the availability of low-cost alternatives in the market are expected to be major stumbling blocks to the market’s growth.
Regional Outlook for Electronystagmography Testing
North America, Latin America, Europe, Asia-Pacific excluding Japan (APEJ), Japan, and the Middle East and Africa make up the global electronystagmography testing market (MEA). Because of lifestyle changes, new product innovations, early treatment adoption, and high health-care spending, North America is expected to dominate the global electronystagmography testing market.
Due to increased awareness and a large research base, Europe is expected to account for the second largest share of the global electronystagmography testing market.
