How Multiple Sclerosis Cause Vision Disturbances: Eye Pain and Blurry Vision

Vision Problems Related to Multiple Sclerosis

Vision Loss

Multiple sclerosis can cause vision loss when the optic nerve that connects the eye to the brain becomes inflamed. This is what we call optic neuritis.

About 50% of the people with multiple sclerosis may experience this condition at least once. It is often the early sign that someone has MS. However, optic neuritis does not always indicate MS. It may also be linked with other medical conditions.

Signs and Symptoms of optic neuritis commonly appear abruptly. They include:

  • Grayish vision
  • Blurred vision
  • Temporary blindness in one eye (especially during an MS flare)
  • Pain while moving eyes

Optic neuritis is rare to happen in both eyes at the same time. Vision loss may progress for a few days before it goes away on its own. The swelling of the optic nerve could endure from 4 to 12 weeks.

As soon as you experience any symptoms of vision loss, inform your doctor immediately. You may be prescribed with IV steroids to treat the first occurrence of optic neuritis. However, the public advised considering higher risks of recurrence when taking oral steroids for optic neuritis.

Although the symptoms can be disturbing or disabling, the best treatment for this may be no treatment at all.

Double Vision

In MS, double vision may occur when the eye muscles responsible for eye movement are not coordinated. Symptoms of double vision may become worse when your eyes are tired. The best way to manage double vision is to rest your eyes.

Unintentional Eye Movements

People suffering from MS may develop small, rapid, and uncontrolled eye movements. They may lose control of their eye movements from side to side and up to down, which is usually termed as a quiver. This condition is called nystagmus which can deter normal vision in severe cases. Medications and special eyeglass prisms may help relieve discomfort and improve vision.
