What Is Primary Open-Angle Glaucoma?
Primary open-angle glaucoma is one of the leading preventable causes of blindness in the world, and it is the most common cause of blindness in African-Americans. Glaucoma is a condition that leads to optic nerve damage and possible irreversible visual loss. Progression of this optic nerve damage can usually be halted with treatment but cannot be reversed once the damage is done.
There are several types of glaucoma, and primary open-angle glaucoma (POAG) is the most common.
In POAG, there are characteristic optic nerve changes (damage) associated with open angles (the area between the iris and cornea) and elevated eye pressure. This is in contrast to other types of glaucoma, which are associated with abnormal angles (for example, narrow-angle glaucoma, closed-angle glaucoma, primary congenital glaucoma, and other secondary glaucomas) or low eye pressures (normal tension glaucoma).

With all types of glaucoma, the nerve connecting the eye to the brain is damaged, usually due to high eye pressure.
