Macular Degeneration


The retina plays a central role in visual perception, enabling you to see objects in your field of vision. Composed of millions of photoreceptor cells at the back of the eye, the retina captures light and converts it into electronic impulses that travel to the brain, where they are converted into images. The macula, at the center of the retina, is responsible for central vision and the ability to distinguish colors. When the macula becomes damaged, loss of vision occurs.



As people age, they may become vulnerable to macular degeneration, the leading cause of blindness in the United States. Age-related macular degeneration (AMD) accounts for 90 percent of severe vision loss. Typically affecting people over the age of 60 — most frequently women — AMD causes a decrease in central vision, making it difficult to read and engage in other tasks that require fine discrimination. Distorted vision and the appearance of wavy lines over the visual field may also result from macular degeneration.

These symptoms can manifest themselves suddenly or progress gradually over time, depending on whether the condition involves “wet” or “dry” macular degeneration.

Wet (neovascular) macular degeneration, the most advanced form of AMD, occurs when abnormal blood vessels forming behind the macula break, releasing blood and fluid. The pressure created by blood and fluids causes the macula to rise from its proper position in the retina, and sustain severe damage. Symptoms appear rapidly with this form of AMD.

With dry (non-neovascular) macular degeneration, the photoreceptor cells that make up the macula gradually break down, eroding the clarity of a person’s central vision. Blurry vision is the first sign of dry AMD, which may affect one or both of the eyes.


For treatment of wet macular degeneration, the ophthalmologists at Cape Fear Eye Associates offer a number of treatment options including injections of Avastin®, photodynamic therapy, and laser surgery.

Intravitreal Injections

Intravitreal injections are used to inhibit the growth of abnormal blood vessels in the retina. By inhibiting growth in this way, we can halt vision loss and, in some patients, even improve vision.

Photodynamic Therapy

Photodynamic therapy (PDT) also helps to slow down vision loss. By injecting a light-activated drug into the body, our ophthalmologists can target the area of the eye where fast-growing abnormal blood vessels form. Light is then directed into the eyes for a brief period, causing the drug to destroy the abnormal growths without damaging surrounding tissue.

Laser Surgery

Laser surgery can also destroy abnormal blood vessels to halt vision loss. However, this type of therapy is not appropriate for most AMD patients. Because laser therapy may also affect adjacent tissue, only patients whose abnormal blood vessels have developed away from the center of the macula should undergo this type of treatment. The ophthalmologists at Cape Fear Eye Associates can determine which treatment option is most appropriate for your condition.

There is no treatment currently available to prevent vision loss for patients with advanced dry macular degeneration. However, there are a number of things you can do to delay and even prevent dry AMD from progressing to the advanced stage.


What You Can Do

Recent studies have shown that the risk of developing both the dry and wet forms of age-related macular degeneration can be significantly reduced by taking high-doses of zinc and certain antioxidants at the recommendation of your eye care specialist. Specific formulations are available on-site at our Fayetteville locations. Current research also indicates that a diet rich in green, leafy vegetables helps to prevent AMD.
