For this test, you are seated on an exam table. The doctor may ask you to
look at his or her nose the whole time the test is done.
- The
doctor first turns your head to one side and then lowers your head to the
table.
- The doctor watches your eyes for nystagmus. Nystagmus is a rapid,
rhythmic movement of the eyes.
- If you get dizzy and the doctor sees nystagmus,
then the doctor knows that the ear pointed to the floor is the affected ear.
- If
the doctor does not see nystagmus, he or she repeats steps 1 and 2 on the other side
to check your other ear.
The timing of the onset of dizziness helps the doctor
locate the cause of the dizziness or vertigo. - The doctor then
helps you back to the upright position.
