About the Symptom

Blurry vision is a symptom in which someone is unable to visually distinguish details or sharp contours of their surroundings.

When to see a doctor

Seek professional care if you experience any of the following symptoms

  • Photophobia

  • Eye pain

  • Visual field defect

  • double vision

Possible causes

Generally, Blurred vision can be related to:

  • Neuromyelitis Optica (NMO)

    Neuromyelitis optica (NMO) is a rare condition in which the immune system damages the spinal cord and the optic nerves.

  • Diabetic macular edema (DME)

    Diabetic macular edema occurs when tiny bulges (microaneurysms) protrude from the vessel walls, leaking fluid and blood into the retina. This fluid can cause swelling (edema) in the central part of the retina (macula) and may lead to vision problems or blindness.

  • Tolosa Hunt syndrome

    Tolosa-Hunt Syndrome is a rare condition characterized by severe headaches behind the eyes, decreased and painful eye movements typically in just one eye. The exact cause is unknown, but it may be related to inflammation in certain areas behind the eye.

  • Macular edema
  • Age-related macular degeneration
  • Cataracts
  • Subcortical hemorrhage
  • Migraine

Related serious diseases

Sometimes, Blurred vision may be related to these serious diseases:

  • Acute glaucoma attack

    A condition caused by high pressures in the eyeball, more common in people with farsightedness. Persons of Black, Asian, or Hispanic descent are at higher risk. The high pressures can cut off blood flow to the eye. Prompt medical attention is needed to prevent permanent blindness.

  • Retinal detachment
