Risk factors
Because chronic forms of glaucoma can destroy vision before any signs or symptoms are apparent, be aware of these risk factors:
Having high internal eye pressure (intraocular pressure)
Being over age 60
Being black or Hispanic
Having a family history of the condition
Having certain medical conditions, such as diabetes, heart disease, high blood pressure and sickle cell anemia
Having certain eye conditions, such as nearsightedness
Having had an eye injury or certain types of eye surgery
Early estrogen deficiency, such as can occur after removal of both ovaries (bilateral oophorectomy) before age 43
Taking corticosteroid medications, especially eyedrops, for a long time.
