Acquired nystagmus
Abstract
Acquired nystagmus is a condition where involuntary, rhythmic eye movements develop after birth. Unlike congenital nystagmus, which is present from birth, acquired nystagmus is often a symptom of an underlying medical condition.
Common Causes of Acquired Nystagmus
Neurological disorders: Conditions such as stroke, multiple sclerosis, brain tumors, and Parkinson's disease can damage the parts of the brain responsible for eye movement control.
Ear disorders: Inner ear problems, like vestibular neuritis or Meniere's disease, can disrupt the balance system and lead to nystagmus.
Eye diseases: Conditions like cataracts, glaucoma, or retinal detachment can affect the visual system and trigger nystagmus.
Medications: Certain medications can cause nystagmus as a side effect.
Head injury: Trauma to the head can damage the brain and nerves involved in eye movement.
Anatomical Considerations
Acquired nystagmus can arise from damage to various components of the oculomotor system:
Brainstem: The brainstem, which houses the nuclei for the cranial nerves controlling eye movement, can be affected by conditions like stroke or tumors.
Cerebellum: The cerebellum, responsible for coordinating movements, can be damaged by disorders like multiple sclerosis or stroke.
Inner ear: The vestibular system in the inner ear helps maintain balance and contributes to eye movement control. Damage to this system can lead to nystagmus.
Extraocular muscles: Conditions like Graves' disease can cause inflammation of the extraocular muscles, leading to nystagmus.
Types of Acquired Nystagmus:
Horizontal nystagmus: The most common type, where the eyes move horizontally back and forth.
Vertical nystagmus: The eyes move up and down.
Rotational nystagmus: The eyes move in a circular or torsional pattern.
Treatment: The treatment for acquired nystagmus depends on the underlying cause. It may involve medications, surgery, or rehabilitation therapy to address the underlying condition and improve eye movement control.
