Age-Related Macular Degeneration

Regular Eye Exams Help Protect Your Eyes From Vision Loss Due to Age-Related Macular Degeneration

Age-related macular degeneration is the number one cause of legal blindness in the United States. In fact, almost 11 million people in our country have some degree of AMD. Some of the effects of this condition can be mitigated with early detection, making regular eye exams your best defence. To understand how we can control this disease, we must understand the makeup of your eye, and the macula.

What is the Macula?

In the very center of your retina lays the macula. The macula is made of a small cluster of cells that are highly sensitive to light. This sensitivity is what creates the details in our vision, allowing us to read and recognize faces. Without a strong macula it becomes difficult to drive or do tasks that require close vision like read a recipe, watch TV, or fix things in the home.

How Macular Degeneration Affects Your Vision

Without the macula’s help the images the retina sends to the optic nerve and on to the brain are blurry or distorted. Your central field of view may appear darkened or have blank spots in it. Over time, you could lose your central vision altogether.

Types of AMD

Age-related macular degeneration comes in two forms: wet and dry. They are divided by the way in which the macula is damaged.

Dry AMD is the most common type of this condition and is less severe than its wet counterpart. Yellow, fatty deposits known as drusen collect on the retina. When they collect around the macula the cells that detect light become damaged. As dry AMD advances it causes loss of vision. Early dry AMD may suddenly change to wet AMD.

Wet AMD is less common but more severe. The blood vessels in your retina may get damaged with age. As your body attempts to replace these blood vessels they are not as strong as the originals, making them prone to leakage and scarring resulting in damage the macular tissue. Wet AMD requires careful monitoring to avoid significant and permanent vision loss.

Detection and Treatment for Age-Related Macular Degeneration

A comprehensive eye exam is vital for detection of age-related macular degeneration. Examining the retina through dilated pupils is the most common form of discovery, but optical coherence tomography (OCT) is a new very effective tool for retinal examinations. OCT is a painless procedure that uses light rays to create a high-resolution image of your eyes.

There is no cure for AMD. Treatment includes ocular injections and laser therapy. These two methods have proven to be effective against the progression of this disease. AMD may be prevented, or at least slowed, through proper nutrition, vitamin intake, and UV protection. If AMD is diagnosed, it can be monitored at home with an Amsler grid.

Age is the biggest factor in the development of AMD, but others include smoking, genetics, and lifestyle. Research has shown that certain vitamins and nutrients are beneficial in preventing AMD. Vitamins C and E, plus zinc have proven particularly useful, and are often found in over the counter supplements designed for eye health. Our optometrists or a pharmacist can help you choose vitamins suitable for your needs.
