Primary Open Angle Glaucoma
This form of glaucoma is the most common type in the U.S. and is often undetectable early on because it can occur in high and normal eye pressures. This type of glaucoma causes optic nerve damage that often results in vision loss.
When the eye drainage canal is suddenly blocked by the iris, this form of glaucoma can cause sudden and severe rise in eye pressure. The condition can be acute or chronic, with acute episodes often resulting in severe pain.
There is no cure for glaucoma and vision lost to glaucoma cannot be restored. However, further vision loss can be slowed or prevented with laser treatment or eye drops to lower eye pressure or glaucoma surgery.
