Daroff_04-5 Voluntary Nystagmus

Identifier: Daroff_04-5 Title: Voluntary Nystagmus Subject: Voluntary Nystagmus; Voluntary Flutter Description: In this video, a woman shows her ability to voluntarily induce an ocular oscillation. It is called “voluntary nystagmus”, although the oscillation consist of back-to-back saccades, such as occurs in ocular flutter. Clues to the voluntary nature of this oscillation are mentioned. At times, however, without eye movements recordings, it may be difficult to distinguish this from an involuntary oscillation as demonstrated in a second patient.
