Symptoms of Glaucoma

Glaucoma symptoms can develop in one or both eyes. The specific symptoms will depend on the type of glaucoma a person is experiencing.
 
Open Angle
For open angle glaucoma, a person usually shows no symptoms in the beginning. For this type, there is no pain, and vision stays normal.
 
However, as the condition progresses, a person with open angle glaucoma may notice the following symptoms:
 
  • Gradual failure of side vision (object in front may be clear, but objects to the side may be missed)
  • Narrowed vision
  • Blindness.
     
Angle Closure
Symptoms of acute angle closure glaucoma may seem the opposite of open angle glaucoma, erupting in a sudden, violent attack.
 
In angle closure glaucoma, the fluid at the front of the eye cannot reach the angle and leave the eye. The angle gets blocked by part of the iris. People with this type of glaucoma have a sudden increase in eye pressure.
 
Angle closure glaucoma symptoms include:
 
  • Severe pain
  • Nausea
  • Redness of the eye
  • Blurred vision.
     
If you have these possible symptoms of angle closure glaucoma, you need to seek treatment immediately. This is a medical emergency. If your doctor is unavailable, go to the nearest hospital or clinic.
