Symptoms

Much of the brain's capacity is dedicated to visual function and eye movements. As a result, many types of neurologic diseases can affect vision in some way. Our service often sees patients who are experiencing symptoms such as:

  • Visual loss due to optic nerve disorders
  • Visual field loss
  • Unexplained visual loss
  • Transient visual loss
  • Visual disturbances
  • Double vision
  • Abnormal eye movements
  • Unequal pupil size
  • Eyelid abnormalities

Conditions

These and other symptoms are frequently caused by one of the following conditions:

  • Multiple sclerosis (MS) and Neuromyelitis optica: A chronic disease of the central nervous system, MS and neuro-visual complications of MS can lead to visual problems
  • Myasthenia gravis: With this complex autoimmune disorder, antibodies destroy neuromuscular connections to cause problems with the nerves that communicate with muscles
  • Pituitary tumors: These, usually benign, brain tumors press against the optic nerves, causing vision problems
  • Migraine: Visual disturbances are one of the common symptoms of migraine
  • Stroke: Dimness or loss of vision in one or both eyes may be attributable to stroke
  • Autoimmune disease: These diseases can often affect the optic nerve and/or parts of the brain that serve vision
  • Benign intracranial hypertension and papilledema
