By chance I vented in a private vertigo group on Facebook about my inability to find a doctor who could accurately diagnose and treat me. A group member posted an article and recommended I find a "neurotologist". I googled "neurotologist" and Hartford, the closest city to me and voila! up popped the Dizzy Clinic for Hartford Hospital and the esteemed Doctor Marc Eisen.
I called and booked an appointment for the following week.
Here is a list the testing he does, taken from his website: http://www.harthosp.org/hearing/BalanceTesting/default.aspx
Balance Testing

The eyes are the window to the ears.
Part of the function of the inner ear is to keep the brain informed
about how the head is moving and where the head is with respect to
gravity. The brain uses this information to make compensatory movements
of the eyes to keep them fixed on what you are looking at. This is a
reflex aptly called the “vestibulo-ocular reflex,” or VOR. Without the
VOR, every time you move your head or walk around, the world would look
like it is bouncing and blurry (picture what happens to the picture on a
hand-held video camera when you walk around with it). By testing the
VOR in certain ways, an assessment can be made about how the inner ears
are working.
At the Dizziness Clinic there are two related types of tests for this that you may have in order to help us diagnose you. These include Video Occulography and Video Nystagmography.
Video Occulography consists of a pair of goggles that
you wear to block your vision, and an infrared video camera that
monitors and records one of your eyes. Dr. Eisen is likely to use this
during a consultation. This method allows him to see eye movements that
can not otherwise be seen.
Video Nystagmography (or VNG) is a
battery of tests performed by the audiologist where eye movements are
monitored in response to different movements of the head, motion of a
light, or a puff of air in your ear canal. A sophisticated pair of
goggles monitor and record both eyes during the testing. The VNG can be
very helpful in diagnosing several of the problems associated with
dizziness. The VNG test battery takes about an hour.
Vestibular Evoked Myogenic Potential (VEMP) Testing is a
brief, non-invasive test that is usually used to assess people with
dizziness. It complements the VNG testing and is often performed at the
same time. While the VNG test evaluates the lateral semicircular canal
and superior vestibular nerve, the VEMP test targets another branch of
the vestibular (balance) system, called the saccule, and the inferior
vestibular nerve.
During the procedure the patient lies down on her back and an electrode
is attached to the skin of the neck. The patient must then raise her
head, unsupported, which tenses the front neck muscles, while a sound
stimulus is played in the ear. The test only takes a few minutes to
perform and causes little or no discomfort. The VEMP test does not cause
dizziness.
The VEMP helps us identify several specific causes of dizziness:
- Superior canal dehiscence. A thinning of the bone between the
superior semicircular canal and the brain causes a dizzy sensation
induced by loud noises.
- Vestibular nerve disorders, such as acoustic neuromas and vestibular neuritis.
