Macular Degeneration

Age-related macular degeneration (AMD) is one of the leading causes of severe vision loss among people over age 50. It negatively affects our ability to see clearly making it extremely difficult or impossible to do many of our daily tasks and activities.

Macular degeneration results from changes to the sensitive central portion of the retina in the back of the eye. The macular area is responsible for clear sharp central vision and is many times more sensitive than the rest of the retina. It is the portion of the eye that allows us to see sharp details and bright colors.

There are two types of macular degeneration dry and wet. The dry form is significantly more common and tends to be less debilitating. It is thought to be a normal change that occurs as we get older, and usually progresses very slowly and gradually.

The wet form, which is less common, can be more debilitating if left untreated. Wet macular degeneration almost always occurs in people who already have dry macular degeneration and oftentimes results in legal blindness. Early detection and management is vital in minimizing damage.

Some of the symptoms of macular degeneration are

A gradual loss of ability to see objects clearly.

Objects appearing distorted in shape or straight lines that appear wavy or crooked.

A gradual loss of clear color vision.

A dark empty area appearing in the center or just off-center of your vision.

Comprehensive eye examinations are the only way to determine the overall health of your eyes and if there are any signs of macular degeneration. If there is leakage, referral to a retinal specialist for treatment is critical. Early detection and management is extremely important.

Who Gets Macular
Degeneration?

If one of your blood relatives has macular degeneration, then you will be more prone to also develop it. Women tend to be at greater risk than men.

Smokers are more prone to develop macular degeneration because smoking causes a decrease of oxygen reaching the macular area of the eyes.

What Can I Do To Prevent
Macular Degeneration From
Occurring?

Wearing sunglasses and brimmed hats outdoors will protect your eyes from the sun. Avoid eating fatty foods and smoking.

Supplementing your diet with a good multivitamin, antioxidants, and omega-3 fatty acids can help lower your risk of developing AMD, and remember to schedule a comprehensive eye examination at least every year.
