The smooth pursuit system allows us to track a moving target.

Smooth pursuit tracking assesses the patient's central vestibular system and is normally un-affected by peripheral lesions (unless there is a spontaneous nystagmus) - although it is susceptible to age related effects.

Testing can be performed horizontally and vertically. This video demonstrates a patient undergoing a horizontal smooth pursuit test.
