Treatment for Macular Degeneration

How is dry AMD treated?

Once dry AMD reaches the advanced stage, no form of treatment can prevent vision loss. However, treatment can delay and possibly prevent intermediate AMD from progressing to the advanced stage, in which vision loss occurs. The National Eye Institute's Age-Related Eye Disease Study (AREDS) found that taking a specific high-dose formulation of antioxidants and zinc significantly reduces the risk of advanced AMD and its associated vision loss. Slowing AMD's progression from the intermediate stage to the advanced stage will save the vision of many people. More information on the AREDS formulation.

How is wet AMD treated?

There are two treatments for wet AMD: laser surgery and photodynamic therapy. Neither treatment is a cure for wet AMD. Each treatment may slow the rate of vision decline or stop further vision loss. The disease and loss of vision may progress despite treatment.

What can I do if I already have lost some vision from AMD?

If you have lost some sight from AMD, don't be afraid to use your eyes for reading, watching TV, and other routine activities. Normal use of your eyes will not cause further damage to your vision.

If you have lost some sight from AMD, ask your eye care professional about low-vision services and devices that may help you make the most of your remaining vision. Ask for a referral to a specialist in low-vision. Many community organizations and agencies offer information about low-vision counseling, training, and other special services for people with visual impairments. A nearby school of medicine or optometry may provide low-vision services.

What can I do to protect my vision?

Dry AMD: If you have dry AMD, you should have a comprehensive dilated eye exam at least once a year. Your eye care professional can monitor your condition and check for other eye diseases. Also, if you have intermediate AMD in one or both eyes, or advanced AMD in one eye only, your doctor may suggest that you take the AREDS formulation containing the high levels of antioxidants and zinc.

Because dry AMD can turn into wet AMD at any time, you should get an Amsler grid from your eye care professional. Use the grid every day to evaluate your vision for signs of wet AMD. This quick test works best for people who still have good central vision. Check each eye separately. Cover one eye and look at the grid. Then cover your other eye and look at the grid. If you detect any changes in the appearance of this grid or in your everyday vision while reading the newspaper or watching television, get a comprehensive dilated eye exam.

Wet AMD: If you have wet AMD and your doctor advises treatment, do not wait. After laser surgery or photodynamic therapy, you will need frequent eye exams to detect any recurrence of leaking blood vessels. Studies show that people who smoke have a greater risk of recurrence than those who don't. In addition, check your vision at home with the Amsler grid. If you detect any changes, schedule an eye exam immediately.

Can my lifestyle make a difference?

Your lifestyle can play a role in reducing your risk of developing AMD.

• Eat a healthy diet high in green leafy vegetables and fish.
• Don't smoke.
• Maintain normal blood pressure.
• Watch your weight.
• Exercise.
