Vision loss from glaucoma is permanent but can usually be prevented with early detection and treatment. Glaucoma management is usually a lifelong process that requires frequent monitoring and constant treatment. Since there is no way to determine if glaucoma is under control based on how a person feels, a person with glaucoma generally should be examined every 3 to 4 months.

If you have experienced a loss of peripheral vision or are having other difficulties with your vision, you should have a complete eye examination.
