What three types comprise gaze nystagmus?

The three types of gaze nystagmus include horizontal, vertical, and resting nystagmus. Horizontal nystagmus is observed when the eyes move side to side, vertical nystagmus is recognized by up-and-down eye movements, and resting nystagmus occurs when the eyes remain in a constant position but are still able to demonstrate involuntary jerking.

In the context of recognizing signs of impairment, understanding these types of nystagmus is crucial for officers administering the Standardized Field Sobriety Test. Each type can indicate different influences or issues affecting a person, particularly in relation to substances like alcohol or neurological conditions.

The other options do not accurately reflect the categories that define gaze nystagmus. While they may involve different forms or causes of nystagmus, they do not represent the specific types that comprise gaze nystagmus in the context of the SFST.
