VNG: Gaze Stability During Fixation

Intended learning outcomes:

1) Determine the optimal way to perform gaze, spontaneous nystagmus, and static position tests.
2) Identify different types of nystagmus and their clinical significance.
3) Differentiate between central and non-central types of nystagmus.
