Nystagmus is characterized by which type of eye movement?

Involuntary, jerking
Voluntary, smooth
Rapid, oscillating
Controlled, rhythmic

The correct answer is: Involuntary, jerking

Nystagmus is characterized by involuntary, jerking eye movements. This condition involves repetitive and uncontrolled movements of the eyes, typically resulting in a pattern of rapid oscillation and then a slower return to a stable position. It can manifest in different forms, but the key identifying feature is that the movements cannot be consciously controlled, making them involuntary. This distinct pattern is crucial for medical professionals and law enforcement to recognize, as it can be an indicator of various conditions, including neurological issues or intoxication. The other types of eye movements mentioned do not capture the involuntary and jerking nature that defines nystagmus.
