Macular Degeneration

​​​​​​​

Macular degeneration, commonly referred to as age-related macular degeneration (AMD), is the single largest cause of sight loss in the developed world and affects more than 10 million Americans. It usually affects people over the age of 60, but has been known to affect those who are younger. It is a painless condition that usually affects both eyes with the loss being experienced in the central vision. It does not affect the peripheral vision, meaning that it does not cause total blindness.
 

What is the macula?

The macula is the most sensitive part of the retina and is responsible for our central vision and what allows us to see fine details with clarity.
 

Varieties of AMD

Wet AMD

Wet AMD is one variety of the condition in which abnormal blood vessels grow into the macula, leaking blood or fluid which then causes scarring and a rapid loss of central vision. Wet AMD can develop suddenly and rapid referral to a specialist is essential as it can be treated if caught quickly.
 

Dry AMD

Dry AMD is the most common variety of age-related macular degeneration and is a gradual deterioration of the retina as the cells die off over time and are not regenerated. Up to 15% of people with dry AMD go on to develop wet AMD, and so any sudden changes in your vision should be followed up with your optometrist as soon as possible.

Symptoms of macular degeneration

Macular degeneration affects each person differently, which means that it can sometimes be difficult to diagnose, particularly as you may not notice any change in your vision early on in the condition. However, as the cells deteriorate, you will start to see an increasing range of symptoms, including:

• Distortion or bends in what should be straight lines (such as lampposts or door frames)

• Dark spots in your central vision

• Fading colors

• Difficulty adapting from dark to light environments

• Blurred vision

• Objects may appear to change shape, size or color, or may move or disappear

• Bright lights may be difficult to tolerate

• Words may disappear while you are reading

Preventative Measures for Macular Degeneration and Nutritional Management

Early Detection and Regular Eye Exams

Regular comprehensive eye exams are crucial for early detection of macular degeneration. Through advanced imaging technologies such as the Zeiss Clarus 500 widefield retinal imaging and Zeiss Cirrus OCT, we can closely monitor the health of your retina and detect any signs of macular changes before they progress to more serious stages. Early intervention can help manage the condition and preserve vision for a longer period.

Lifestyle Modifications and Nutritional Support

While macular degeneration is influenced by genetic factors, certain lifestyle choices can play a pivotal role in protecting your eye health. One of the most significant ways to reduce your risk is through nutritional management.

• Antioxidants and Vitamins: Studies have shown that specific nutrients can support retinal health and potentially reduce the risk of macular degeneration. A diet rich in antioxidants, particularly vitamins C and E, as well as zinc, copper, and beta-carotene, may help protect the eyes from oxidative damage that can contribute to macular degeneration. Additionally, the AREDS2 formula (a combination of vitamins C, E, zinc, copper, and lutein/zeaxanthin) has been proven to slow the progression of the disease in patients with intermediate macular degeneration.

• Omega-3 Fatty Acids: Omega-3 fatty acids, found in foods such as fish (especially salmon and sardines) and flaxseed, have been linked to a reduced risk of macular degeneration. These healthy fats may help reduce inflammation in the retina and support overall retinal health.

• Lutein and Zeaxanthin: These carotenoids, found in leafy green vegetables (such as spinach, kale, and collard greens) and other colorful fruits and vegetables, are particularly beneficial for the macula. Lutein and zeaxanthin act as natural filters of blue light and help protect retinal cells from damage caused by UV rays and oxidative stress.

Healthy Habits for Eye Health

In addition to proper nutrition, certain lifestyle habits can help protect against macular degeneration. These include:

• Avoiding smoking: Smoking is a significant risk factor for macular degeneration. Quitting smoking can reduce your risk and protect your eye health.

• Protecting your eyes from UV light: Wearing sunglasses that block UV rays can help prevent further damage to the macula.

• Maintaining a healthy weight and exercise routine: Regular physical activity improves circulation and may help reduce the risk of developing macular degeneration.

• Managing cardiovascular health: Conditions like hypertension and high cholesterol can exacerbate eye health issues, so keeping these in check can benefit overall eye health.

By combining regular eye exams, lifestyle adjustments, and a nutritious diet, you can help lower the risk of macular degeneration or slow its progression. Our team is here to guide you in adopting these preventative measures and offer personalized advice to keep your vision sharp for years to come.
