Glaucoma is characterized by optic nerve damage which results in vision loss, and elevated eye pressure (intraocular pressure) is the primary risk factor. There is growing evidence that other factors may predispose a person to glaucoma damage, including circulation to the eye and optic nerve.
If your eye doctor tells you that you have increased eye pressure but your optic nerve is not damaged, then you do not have glaucoma. Not every person with elevated pressure will develop the disease, either. Some people with high pressure never develop glaucoma because their optic nerve can tolerate the pressure. A high level of eye pressure may be normal for some people, but it is important for an eye care professional to determine what level is normal for you.
