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, Asian or Hispanic
• Having a family history of glaucoma
• Having certain medical conditions, such as diabetes, heart disease, high blood pressure and sickle cell anemia
• Having corneas that are thin in the center
• Being extremely nearsighted or farsighted
• Having had an eye injury or certain types of eye surgery
• Taking corticosteroid medications, especially eyedrops, for a long time
