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.
Answer: You are right to be concerned, but having increased eye pressure does not necessarily mean that you have glaucoma. Increased eye pressure does, however, put you at risk for developing the disease. Glaucoma is present when the optic nerve is damaged.
