A member asked:

Im constantly have a dizzy/disbalance/foggy head feeling, my ent said it's chronic hyperventilation, can this cause a nystagmus?

A doctor has provided 1 answer

Yes: It's called hyperventilation induced nystagmus and is a common way we test people to tell whether or not they have say, an acoustic neuroma of the 8th cranial nerve vs. a vestibular disease or neuritis of some sort. If you already have nystagmus this maneuver can increase it.
