WebbBy definition, nystagmus starts by a slow movement of the eye away from the visual target. The second movement brings the eye back to the visual target. If the second movement is slow, the nystagmus is said to be pendular. If this second movement is quick, the nystagmus is called jerk nystagmus. WebbAgain the counter-movement of eyes and slow return to midline clarify that the patient has intact brainstem.
