Procedures & Services > Diagnostic Testing > Electro-Oculogram (EOG)

Your eyes will be dilated for this test. Electrodes will be placed on the forehead and around the eyes. We ask that you do not apply creams, lotions or cosmetics the day of testing.

During the test, you will place your chin in a chin rest that is attached to a special bowl. Inside the bowl will be three lights. These lights will turn on and off in an alternating sequence. You will then follow the movement of these lights with your eyes in a back and forth motion. The computer will average these responses to changing lights. Please allow one and a half hours for testing.
