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.
