Rotational Nystagmus is a condition in which the eyes constantly make involuntary movements while the head is rotating. There are several synonyms for this condition, including vestibular nystagmus, positional nystagmus, optokinetic nystagmus, and gaze-evoked nystagmus. These terms all refer to the same condition but may be used in different medical contexts. Vestibular nystagmus specifically refers to nystagmus caused by inner ear problems, while optokinetic nystagmus is caused by visual stimuli. Positional nystagmus refers to nystagmus that occurs in certain head positions, and gaze-evoked nystagmus occurs when the eyes move involuntarily in different directions. Regardless of the terminology used, all cases of rotational nystagmus require medical attention.
