![]() ![]() Once you know which canal the otoconia (“crystal”) is in, you can be most effective with the treatment options. You do not have to have these special goggles but it makes diagnosing BPPV more accurate. Professionals can determine which canal the otoconia is in based on these eye movements using Infrared Frenzel Goggles (to view nystagmus patterns) with certain testing positions. It can be scary and other symptoms may occur (nausea, imbalance, anxiety, etc.). This type of vertigo rarely affects hearing. Your eyes follow the signal of the otolith when it moves in the canal and it causes nystagmus (abnormal eye movements) – which is what causes the room to feel like it is spinning, when you are not actually moving.Ĭertain positions such as lying down, looking up and turning over in bed may cause symptoms of vertigo. This sends a false signal to the brain that you are moving. When enough of these particles accumulate in one of the canals or get knocked off the bed of gel (like with falling down or whiplash), the otoconia interfere with the normal fluid movement that these canals use to sense head motion. It occurs when some of the calcium carbonate crystals, “otoconia” that are normally embedded in gel in the Utricle become dislodged and migrate into one or more of the 6 fluid-filled Semicircular Canals, where they are not supposed to be. Benign Paroxysmal Positional Vertigo ( BPPV)īPPV is a mechanical problem in the inner ear.
