Videonystagmography (VNG) is a valuable diagnostic tool used to assess patients with dizziness, vertigo, or balance issues. Let’s delve into the details:
Gaze Test: During the gaze test, the patient maintains a steady gaze without extraneous movements. Abnormalities in eye movements may indicate central or peripheral vestibular system lesions. The VNG system captures and records these eye movements accurately and easily.
Advantages of VNG:
Higher Resolution: VNG offers higher resolution compared to traditional electrode-based electronystagmography (ENG) tests.
Stability: VNG recordings are stable, providing better quality data.
Ease of Application: VNG goggles are quickly applied to the patient, eliminating the need for electrode preparation.
Recording Recall: VNG recordings can be recalled later for analysis1.
Pathways Involved in VNG:
VNG assesses gaze stability without fixation, spontaneous nystagmus, and positional nystagmus.
It allows audiologists to examine eye movements and assess the functional integrity of the vestibular system.
Clinical Importance:
VNG helps diagnose and treat dizziness by identifying vestibular abnormalities.
It plays a crucial role in understanding eye movement patterns and maintaining visual acuity.
Remember, VNG is a powerful tool aiding in accurate diagnosis and improving patients’ quality of life. If you need further information, feel free to ask! 😊👂
