Final answer:
Nystagmus resulting from vertical rotation could be Upbeat or Downbeat Nystagmus, characterized by vertical upward or downward movement respectively.
Step-by-step explanation:
The form of Nystagmus that would result from vertical rotation can be Upbeat Nystagmus or Downbeat Nystagmus, but without additional context, it is not possible to provide a definitive answer. Upbeat Nystagmus is characterized by eye movements where the fast phase goes vertically upward in the coordinate system.
Conversely, Downbeat Nystagmus features a fast phase that moves vertically downward in the coordinate system. If the question pertains to an upward movement seen in a patient after vertical rotation, Upbeat Nystagmus would be the likely form. Meanwhile, if the eyes move downward following vertical rotation, Downbeat Nystagmus would be indicated.
