Aging may increase risk of eye disease
Treatment can slow down loss of vision

An estimated 13 million to 15 million Americans show evidence of age-related macular degeneration, a progressive eye condition that can destroy "straightahead" vision, according to Dr. Marty Schneider, therapeutic optometrist.

"February is AMD Awareness Month, and we encourage all people, especially those at higher risk for this disease, to familiarize themselves with the potential symptoms and need for regular eye examinations," Schneider said. "To help people better understand this disease, we've prepared a list of frequently asked questions about AMD."

Q: What is AMD?

A: AMD stands for agerelated macular degeneration, a disease that breaks down the macula- the light sensitive portion of the retina that allows people to see fine detail. It blurs the straightahead vision required for activities such as reading and driving.

Q: What causes AMD? A: The causes of AMD are still unknown. One form of AMD, dry, may be caused by aging and thinning of the macular tissues, pigment deposits in the macula or a combination of the two. The other form of AMD, wet, results when new blood vessels grow beneath the retina and leak blood and fluid. This leakage causes retinal cells to die and creates blind spots in central vision.

Q: Who is at risk for AMD?

A: Risk factors for AMD include smoking, high blood pressure, obesity and family history of AMD. Also, Caucasians and females are more prone to AMD.

Q: What are the symptoms of AMD?

A: Early symptoms of AMD include blurred vision or dark spots in the center of vision. The symptoms can appear painlessly and gradually, making early detection and treatment essential.

Q: How can AMD be detected?

A: Early-stage AMD can be detected through a comprehensive eye exam that includes a visual acuity test, dilated eye exam and tonometry. If AMD is detected, further tests may be required.

Q: Can AMD be cured?

A: There is no cure for AMD at this time. There are, however, certain treatments that can slow or minimize vision loss and, in some cases, even improve vision.

Q: How is AMD treated?

A: There are several treatment options one's eye doctor may consider, including vitamins, drug therapy or laser surgery for wet AMD.
