Dizziness is one of the most common complaints people bring to their primary care physician. It is a problem that can affect individuals of any age, but it is more of an issue for older adults. We offer a comprehensive battery of tests that are designed to evaluate a patient's balance system. We begin by obtaining a thorough case history that includes a detailed description of the specific balance problems. Videonystagmography procedures are then used to record and analyze eye movements and help determine how well the balance system is working. This new state-of-the-art, computer-based instrument is used to assist in the diagnosis and treatment planning for the patient's balance disorder.
The word "dizzy" can mean different things to different people. It can mean "light-headedness," or a "floating" sensation and it can also mean a merry-go-round type of "spinning" feeling also known as vertigo. As part of our case history, we define the type of problem and then discuss severity, and when, where and how often the problem occurs. We will ask about your individual lifestyle and medical history that will help us to better understand your specific problem.
These tests are designed to examine the cause of the dizziness. Depending upon the patient, either electronystagmography (ENG) or videonystagmography (VNG) will be chosen. ENG uses several electrodes which are taped around the eyes while VNG utilizes infrared video goggles to detect and record very small eye movements. These movements are recorded in response to changes in head position, watching moving objects move across the visual field, sudden movement of the body or head as well as stimulation of the ear canal with warm or cool water or air.
