Final answer:
Peripheral vertigo is associated with peripheral nystagmus characterized by abnormal eye movements due to inner ear conditions like benign paroxysmal positional vertigo or Ménière's disease.
Step-by-step explanation:
Peripheral vertigo is associated with a type of nystagmus called peripheral nystagmus.
Peripheral nystagmus is characterized by spontaneous rhythmic eye movements that occur in response to abnormal signals from the semicircular canals in the inner ear. These abnormal signals can be caused by conditions such as benign paroxysmal positional vertigo or Ménière's disease.
For example, in benign paroxysmal positional vertigo, the movement of calcium carbonate crystals into the semicircular canals disrupts the normal balance of fluid and motion detection, leading to abnormal eye movements and episodes of dizziness.
