Not all dizziness is caused by neurological issues. Often it can be due to a combination of Binocular Vision Dysfunction (BVD), and difficulties with the vestibulo-ocular connection. The use of prism or microprism can be used to alleviate most of these symptoms, which is used to treat a subtle eye misalignment. These misalignments are often too small to be seen on a routine eye visit but require a longer more in-depth look at the binocular function.
Dizziness when rising from sitting and dizziness when rolling over in bed can also be signs of POTS (postural orthostatic tachycardia syndrome). An extensive neurovisual exam will let us know if we need to incorporate both prism and a referral to cardiology to rule out this condition.
There are also several conditions of the ear that can cause a patient to be dizzy, which will also be ruled out during the neurovisual exam with Dr. Sarah. In this case, special ear plugs can be used to reduce the symptoms, or a referral to an ENT will be advised depending on the condition suspected. Most patients find that they have a significant reduction in their dizziness with the use of prism.
Nausea is another symptom that can often be confused with dizziness when it comes to binocular vision dysfunction and vertical misalignments. These patients will also have difficulty walking without support, and will frequently use a cane or walker to get around.
Driving in the car can be difficult whether a passenger or a driver. The patient can experience severe dizziness due to the moving vehicles beside them, and this can trigger nausea/dizziness. Some even describe it as anxiety because they feel so unsafe and uncomfortable driving.
