Bell's phenomenon was graded as 1. positive if there was upward eye movement, 2. negative if there was downward eye movement, and 3. zero if there was no eye movement. 4. Grade + 2 indicated the presence of Bell's phenomenon with upward and strong eye movement
Bell's phenomenon describes the reflex upward movement of the front of the eyeball when the eyelids close (or blink). Because the cornea is positive with respect to the retina, this causes a deflection in derivations containing electrodes placed near the eyes
