Hope For Those With Age-Related Macular Degeneration

Age-related macular degeneration (AMD) is the leading cause of irreversible visual impairment in patients over the age of 50 in the United States. Although there currently is no cure, there is hope for those with AMD.

As part of Age-Related Macular Degeneration/Low Vision Awareness Month in February, Edwin Stone, M.D., Ph.D., professor of ophthalmology and visual sciences with University of Iowa Health Care, urges people to be screened for age-related vision problems by having regular eye exams and talking with their eye doctor about new treatments and low vision resources that are available.

"The early stages of macular degeneration are easily detectable by a dilated eye examination. Knowing that one is mildly affected with this disease allows a person and their doctor to be more vigilant for changes that could be treated with existing methods," said Stone, who also is a Howard Hughes Medical Investigator.

Macular degeneration is a progressive, usually painless disease that affects the macula, the central portion of the retina at the back of the eye responsible for central vision, causing central vision to blur, but leaving peripheral vision intact. Thus, it is extremely uncommon for AMD to lead to total blindness.

"We are continuing to seek new treatments for people with AMD," Stone said. "At the University of Iowa, we are studying the genetics of macular degeneration in an attempt to understand its basic causes. We believe that if we can understand the basic causes of the disease that we will be able to develop a safe, low-cost preventive treatment that will be useful on a societal scale."

Central vision loss does not have to mean loss of independence or quality of life. If you have lost some of your central vision, ask your eye doctor about low vision rehabilitation. He or she can provide low vision services or refer you to local agencies that can help.

Early detection and treatment is the best defense against losing your vision. Thus, it is a good idea to see your eye doctor for a complete eye exam at least every one to two years.
