Symptoms of glaucoma depend on the type and the stage of disease.

Open-angle glaucoma

  • Usually has no symptoms in the early stages of the disease.
  • Can cause patchy blind spots, usually on the sides (periphery), but sometimes in the center.
  • May cause “tunnel vision” at later stages of the disease.

Angle-closure glaucoma 

  • Severe eye pain
  • Eye redness
  • Severe headache
  • Nausea and vomiting
  • Blurred vision
  • Halos or rings around lights
  • Loss of vision
If you have these symptoms seek emergency medical treatment immediately.
