Preventing Macula Degeneration

Age-Related Macula Degeneration (ARMD) is a progressive disease that damages the area of the eye that is responsible for color, clarity and visual details, the macula. If the integrity of the macula is compromised by blood, fluid, or tissue changes the result is blurry and distorted vision. Vision loss can occur suddenly or slowly.

Causes of Macula Degeneration

There are causes of ARMD that are beyond our control and there are causes that we can control.

The Uncontrollable Factors: Age, Family History, Skin and Eye Pigment

The Controllable Factors: Smoking, Diet, Ultraviolet Exposure, Exercise

Of the factors within our control, I’m going to address what we eat.eyes and nutrition

In 2006, the researchers at the National Eye Institute began a study to see if they could improve on the 2001 Age Related Eye Disease Study (AREDS). A list of FAQ is available here . The results of the studies show that taking a supplement with high levels of specific antioxidants and zinc can reduce the risk of progression in people with moderate to advanced macula degeneration. The level of vitamins and minerals in the AREDS2 formula is difficult to achieve from diet and standard multivitamins alone so a dietary supplement is available.

After your eye examination, I may recommend taking a AREDS2 supplement. This supplement is easily found with the other vitamins and supplements in the pharmacy and super market.

I also recommend trying to eat more foods that contain the nutrients in the AREDS2 formula: Vitamin C (500mg), Vitamin E (400IU), Zinc (80 mg), Copper (2mg), Lutein (10mg) and Zeaxanthin (2mg).

  Lutein and Zeaxanthin can be obtained in green leafy vegetables and other foods such as eggs.

Most of us are familiar with Vitamin C, it is in fruits and vegetables, including oranges, grapefruit, strawberries, green peppers and tomatoes.

Vitamin E is fat soluble and found in nuts, sweet potatoes and fortified cereals.

Essential Fatty Acids (EFA) are in fatty fish like tuna, salmon, whole grain foods, chicken and eggs.

Zinc is obtained in extra lean red meat, poultry, liver, shellfish, dairy, whole grains and legumes.

This might sound a bit like the Mediterranean diet. There is ongoing research to see if a heart-healthy diet of plant-based foods, oils, fish, lean meats and whole grains can reduce the development of ARMD. Stay tuned.

What is Macular Degeneration

Age Related Macular Degeneration (AMD) occurs in the macula in the back of the eye. The macula is part of the retina and contains the “cones,” a type of nerve cell responsible for clear vision and color vision. When AMD develops, the cones are disturbed and vision is significantly and negatively effected.
There are two types of AMD – wet and dry. The wet form is less common, but can progress quickly and profoundly. The symptoms are the same – blurred central vision, distorted central vision and missing areas of vision. A person with advanced AMD would not be able to distinguish facial features when looking straight ahead, but peripheral areas would still be visible.

Who gets AMD?

Many things contribute to the risk of developing AMD: age, race, family history, history of smoking, exposure to UV light, obesity, hypertension and a high fat diet. Some of these risks factors are controllable and prevention is recommended. Early AMD does not always have symptoms. Regular dilated eye exams can increase awareness and prevent devastating vision loss.
