What are the common symptoms of glaucoma?

Signs and symptoms of glaucoma depend on the type and advancement of one’s condition. Some people may be asymptomatic until severe vision damage has occurred. Glaucoma can occur in one or both eyes. 
Signs and symptoms of open-angle glaucoma include:
  • Patchy blind spots in one’s peripheral or central vision (usually in both eyes)
  • Tunnel vision (later sign)
Signs and symptoms of acute angle-closure glaucoma include:
  • Eye pain
  • Nausea and vomiting
  • Severe headache
  • Blurred vision
  • Eye redness
  • Halos around lights
*In many people with angle-closure glaucoma, there are no symptoms at first and the condition develops slowly. This causes people to not realize they have it until they experience an attack. If you experience any of the signs and symptoms of an acute angle-closure glaucoma attack listed above, it is imperative that you seek emergency medical care. An acute angle-closure glaucoma attack is a medical emergency. Complete blindness can occur.*
