Understanding Age-Related Macular Degeneration and How to Combat It


Age-related macular degeneration (AMD) is a leading cause of vision loss, affecting millions of people, particularly those over the age of 50. As its name suggests, AMD is age-related and impacts the macula—the small central portion of the retina responsible for sharp, central vision. While there is no complete cure for AMD, there are proven ways to slow its progression and protect your vision. This blog will help you understand age-related macular degeneration and explore the role of AREDS2 supplements and other AMD vitamins in combating this condition.

What is Age-Related Macular Degeneration?

Age-related macular degeneration occurs when the macula begins to deteriorate, leading to blurred or reduced central vision. This can make activities such as reading, driving, and recognising faces challenging. AMD primarily comes in two types:

  1. Dry AMD (Non-exudative): This is the more common form, where the macula thins over time. It progresses slowly but can lead to significant vision loss if left unmanaged. People with dry AMD are also more at risk from developing wet AMD.
  2. Wet AMD (Exudative): This less common but more severe form occurs when abnormal blood vessels grow under the retina, leaking fluid and blood. Wet AMD can lead to faster and more pronounced vision loss. Current treatment options usually involve injections in the eye.

What Causes AMD?

The exact cause of age-related macular degeneration is not fully understood, but a combination of genetic and environmental factors contributes to its development. Key risk factors include:

  • Age: AMD is most prevalent in people over 50.
  • Genetics: A family history of AMD increases the risk.
  • Lifestyle Factors: Smoking, poor diet, and prolonged exposure to UV light can elevate the risk.
  • Underlying Health Conditions: Conditions like high blood pressure and cardiovascular disease can contribute to AMD.

Recognising the Symptoms of AMD

Early-stage AMD may not present noticeable symptoms. As the disease progresses, you may experience:

  • Blurred or fuzzy vision.
  • Difficulty reading or recognising faces.
  • Dark or blank spots in the centre of your vision.
  • Distorted vision, where straight lines may appear wavy. Using an Amsler grid can help detect and monitor this. We have included an Amsler grid below, designed to be printed out for people to use at home.

If you notice any of these symptoms, consult an eye care professional promptly for evaluation and potential treatment.

How to Combat Age-Related Macular Degeneration

While there is no cure for AMD, adopting certain lifestyle changes and incorporating AREDS2 supplements and other targeted AMD vitamins can help slow its progression and protect your vision.

1. Adopt a Healthy Lifestyle

A balanced diet rich in leafy green vegetables, fish, and fruits can support overall eye health. Foods high in omega-3 fatty acids, such as salmon and mackerel, are particularly beneficial. Additionally, quitting smoking and wearing sunglasses to protect your eyes from UV light can reduce the risk of AMD.

2. AREDS and AREDS2: A Proven Approach

The Age-Related Eye Disease Studies (AREDS and AREDS2) have shown that specific combinations of vitamins and minerals can help slow the progression of AMD. The original AREDS formula included:

  • Vitamin C 500mg
  • Vitamin E 400IU
  • Beta-carotene 15mg
  • Zinc 80mg
  • Copper 2mg

However, the AREDS2 study refined this formula, making it more effective and safer for long-term use, especially for smokers who were at risk when taking beta-carotene. The improved AREDS2 formula includes:

  • Vitamin C 500mg
  • Vitamin E 400IU
  • Zinc 80mg OR 25mg –  the AREDS2 study found that 25mg is just as effective as 80mg, with less potential for side-effects.
  • Copper 2mg
  • Lutein 10 mg and Zeaxanthin 2mg: Added to replace beta-carotene, these carotenoids help filter harmful blue light and support the macula.

AREDS2 supplements are now widely recommended for those already experiencing AMD. These supplements help slow the progression of the disease and maintain better vision for longer. Recent studies have also shown that AREDS2 supplements can help even in late stage AMD, so they are helpful in most stages of AMD. Other nutrients to complement the AREDS2 formula include: Meso-Zeaxanthin and omega-3 fatty acids. Though not part of the final AREDS2 formulation, research supports the role of meso-zeaxanthin and omega-3s in promoting retinal health.

Why AREDS2 Supplements and Vitamins Are Effective

The AREDS2 formula is specifically designed to combat AMD by providing the eyes with essential nutrients that support macular health. Here’s how each component works:

  • Vitamin C and Vitamin E: These antioxidants help reduce oxidative stress and prevent damage to the retina.
  • Zinc: Supports the structure of the retina and enhances the protective effect of antioxidants.
  • Copper: Included to prevent copper deficiency anaemia, which could be induced by high levels of zinc.
  • Lutein and Zeaxanthin: These carotenoids accumulate in the retina and macula, providing a natural shield against blue light and reducing oxidative stress. 

Other nutrients helpful in AMD include: 

  • Omega-3 Fatty Acids: While not part of the final AREDS2 formula, omega-3s support the overall health of the retina and reduce inflammation.
  • Meso-zeaxanthin: Is a nutrient and powerful antioxidant predominantly found in the retina, where it supports eye health by protecting against oxidative stress and enhancing visual function, especially when combined with other carotenoids like lutein and zeaxanthin.

Choosing the Right AMD Supplements

When choosing AMD supplements, ensure they follow the AREDS2 formulation. The dose is also very important – many ‘AREDS2’ supplements actually don’t have the right amounts specified in the formula. For example, they may only have 10mg zinc, but the AREDS2 formula actually specifies 25mg zinc for the formula to be effective. High-quality AREDS2 vitamins can be found at trusted providers like Vision Defender. Our range of eye health products includes AREDS2 supplements, specifically formulated to meet the needs of those looking to support their eye health and combat AMD.

How to Take AREDS2 Supplements

For those diagnosed with intermediate or advanced AMD, taking AREDS2 vitamins as directed by your eye care professional can help slow disease progression. It is recommended to take these supplements daily and as part of a balanced diet. Consult your doctor before starting any supplement regimen, especially if you have existing health conditions or are taking other medications.

Additional Tips for Managing AMD

  • Regular Eye Exams: Early detection is key to managing AMD effectively. Regular check-ups can help monitor any changes in your eye health.
  • Exercise: Regular physical activity can improve circulation and reduce the risk of AMD progression.
  • Healthy Diet: Incorporate foods rich in antioxidants and omega-3 fatty acids to support your eye health.

Conclusion

Age-related macular degeneration is a serious condition that can significantly impact your quality of life. Understanding the disease, recognising its symptoms early, and taking proactive steps—including the use of AREDS2 supplements and other AMD vitamins—can make a substantial difference in maintaining your vision. By incorporating these steps and prioritising your eye health, you can combat the effects of AMD and enjoy clearer vision for years to come.
