Glaucoma is a disease that damages your eye's optic nerve. This usually happens when fluid builds up in the front part of your eye. That extra fluid increases the pressure in your eye which causes damage to the optic nerve.
The most common type of glaucoma is Primary Open Angle Glaucoma. This is a gradual build up of pressure when the eye does not drain fluid as well as it should. This type of glaucoma is painless and causes no vision changes at first.
Angle Closure Glaucoma or Closed Angle Glaucoma is when your iris is very close to the drainage angle in their eye. The iris can end up blocking the drainage angle. When the drainage angle gets blocked, the eye pressure rises very quickly. This is an emergency and you should call our office right away if you experience any sudden blurry vision, severe eye pain, headache, or see halos.
