Nystagmus is commonly associated with which condition?

Nystagmus, which refers to involuntary eye movements, is commonly associated with true vertigo. This condition typically arises from issues affecting the vestibular system, which is responsible for balance and spatial orientation. When there is a disturbance in this system, such as from inner ear problems, it can lead to sensations of spinning, dizziness, or imbalance, which are characteristic of vertigo.

As the brain attempts to make sense of conflicting signals from the inner ear and other sensory pathways, it can result in abnormal eye movements, or nystagmus. This connection between nystagmus and vestibular disorders explains why true vertigo is the most relevant condition in this context.

Other conditions listed, such as glaucoma, obstructive sleep apnea, and chronic bronchitis, do not have a direct association with nystagmus. While these conditions may have their own ocular or systemic implications, they do not typically result in the eye movement abnormalities seen in nystagmus.
