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.
Ocular hypertension is an above-normal increase in the pressure in your eyes with no detectable changes in vision or damage to the eye structure. The term is used to distinguish people with elevated pressure from those with glaucoma, a serious eye disease that causes damage to the optic nerve and vision loss.
