Eye Care | Macular Degeneration

Macular Degeneration Age-related macular degeneration (AMD) is a common eye disease associated with aging that gradually destroys sharp, central vision. It is one of the leading causes of legal blindness and vision impairment in older Americans.

The progression of AMD can be slow or rapid, but the deterioration of central vision generally occurs over a period of a few years. If you experience the following, see your ophthalmologist right away:

• Straight lines appear wavy
• Difficulty seeing at a distance
• Decreased ability to distinguish colors
• Inability to see details, such as faces or words in a book
• Dark or empty spots block the center of your vision

Although the exact cause of macular degeneration is unknown, several studies have shown the following individuals may be at risk:

• People over age 50
• People with hypertension
• People that smoke
• People with a family history of AMD

For individuals with the "wet" form of macular degeneration (the rarer, but more severe form) conventional laser treatment and photodynamic therapy (PDT) treatment is used. PDT is used to reduce the risk of moderate to severe vision loss in patients with a few very specific forms of "wet" macular degeneration. Other experimental treatments that are being investigated include, intraocular antineovascular injections and the insertion of a "retinal chip" to restore vision loss.

For the "dry" form of AMD (the most common form), studies have found that high levels of zinc and antioxidants play a key role in slowing the progression of macular degeneration in advanced cases.

Early detection and treatment is the best defense against losing your vision. If you are at risk for macular degeneration, see your ophthalmologist for a complete eye exam at least every one to two years. If your vision has been reduced, low vision rehabilitation resources can help you maintain an excellent quality of life.
