Healthy nutrition and vitamin supplements can play a pivotal role in slowing age-related macular degeneration (AMD). Recent clinical data from AREDS demonstrated that those at high risk for AMD reduced their chances of advanced AMD by 25 percent when taking antioxidant vitamins C, E, beta-carotene and zinc together.

Vitamin A

Vitamin A is an essential micronutrient required for numerous biological processes, including vision, cell growth and development, intercellular communication and reproduction. Furthermore, Vitamin A serves as a potent antioxidant. You can find vitamin A both in plant and animal foods. When taken orally, vitamin A is absorbed as retinal or its aldehyde derivative 11-cis-retinal and converted to various retinoid metabolites that play critical roles in cell functioning. Vitamin A is necessary for normal cell turnover, protein synthesis and the formation of rhodopsin – a pigment involved in night vision – as well as for maintaining immune function and epithelial cells. Dietary sources of vitamin A include meat (especially liver), fish, green vegetables and fruits as well as fortified cereals and low-fat dairy products containing this nutrient. If excessive quantities are consumed then vitamin A toxicity could occur. Symptoms depend on the amount consumed, but may include headache, nausea and elevated liver function test results. An overdose of synthetic vitamin A compounds such as retinyl palmitate is potentially fatal; however, natural sources usually produce no harm.

Studies have demonstrated the efficacy of diets rich in antioxidants and omega-3 fatty acids to impede dry age-related macular degeneration. Supplements containing these elements may be purchased from pharmacies or online. According to one National Eye Institute study, taking both vitamins reduced wet macular degeneration risk for those at higher risk by 25%.

Age-related macular degeneration patients presenting with wet macular degeneration typically benefit from intravitreal injections of a drug that blocks an enzyme involved in blood vessel growth under the macula. Additional potential treatments, including retinal cell transplants, radiation therapy, gene therapies and agents that block formation of vascular endothelial growth factor have yet to be fully explored as viable treatments.

Vitamin C

Researchers published a groundbreaking study in October 2001 in Archives of Ophthalmology that revealed how high doses of vitamins C, E, beta-carotene and zinc significantly slowed macular degeneration progression for patients with extensive intermediate-size drusen or noncentral geographic atrophy in one eye. Furthermore, adding lutein or zeaxanthin significantly reduced risk for advanced macular degeneration in this patient group.

Ocular vitamins like vitamin C can be particularly helpful because they neutralize free radicals – highly reactive molecules which contribute to macular degeneration by way of oxidative stress and can be activated by sunlight, smoke and certain medications – helping neutralize these reactions and thus slowing macular degeneration progression as well as cataract development.

Vitamin C has long been recognized for its beneficial effects on eye and immune system health, reducing inflammation and free-radical damage caused by free radicals. You can find vitamin C in fruits, vegetables and dietary supplements.

Multiple studies indicate that increasing vitamin D intake could prevent macular degeneration from starting and retard its progress in those already suffering from the condition. Omega-3 fatty acids DHA and EPA could also potentially lower risk of macular degeneration.

The Age-Related Eye Disease Study (AREDS) and other clinical trials have demonstrated that taking high doses of vitamins C, E, lutein and zinc significantly slows macular degeneration progression and vision loss; however, their benefits do not appear for people who exhibit minimal AMD symptoms and do not show evidence of macular degeneration.

Though research supporting the benefits of diet and nutritional supplements are encouraging, further investigation needs to be completed to ascertain exactly how these substances impact eye health. For the best macular degeneration treatment plan, regular visits with an ophthalmologist, proper nutrition, and an absence of smoking or excessive alcohol use must all be part of an all-encompassing eye care program.

Vitamin E

Vitamin E, while not a cure for macular degeneration, has been demonstrated to slow its progression and lower risk. Studies have also demonstrated this is true of cataract formation as well. While available in multivitamins and various supplement formulations for macular degeneration such as the AREDS formulation containing other nutrients like lutein/zeaxanthin/omega 3 fatty acids/zinc and copper; vitamin E was proven to significantly lower risk by significantly slowing progression over time in one such study conducted over 15 years time!

Vitamin E is an antioxidant that protects cell membranes against oxidative damage and has various important biological roles, including producing certain hormones and supporting immunity. According to studies, Vitamin E may also lower risk factors associated with heart disease, cancer, and neurodegeneration.

The Medical Journal of the American Academy of Ophthalmology recently conducted research that suggests vitamin E could slow macular degeneration progression for individuals in early stages, likely due to its antioxidant and anti-inflammatory properties.

Effects may not be as strong in those with advanced AMD; therefore, more research must be conducted in order to ascertain its efficacy in preventing or slowing advanced macular degeneration progression.

A large randomized trial involving female health professionals revealed that 10 years of alternate-day supplementation with 600 IU of natural-source vitamin E did not have any significant beneficial or detrimental effect on incident AMD (defined as reduction of best corrected visual acuity to 20/30 or worse), or progression. Both groups experienced similar rates of AMD progression. Furthermore, those taking placebo experienced more diabetic retinopathy and myopic degeneration; suggesting longer term or increased dosing might be more effective.

Beta-Carotene

Beta-carotene is an antioxidant found naturally in our bodies that works to ward off age-related macular degeneration, night blindness and dry eyes. Furthermore, it protects against free radical damage by neutralizing reactive oxygen molecules which cause eye disease or health complications; especially sensitive areas include cells and DNA damage which oxidants cause. Antioxidant vitamins like C and E as well as carotenoids like lutein, zeaxanthin meso-zeaxanthin and cryptoxanthin can neutralize free radicals which protect from oxidative stress by protecting against free radical damage caused by reactive oxygen molecules; also aiding eyes against potential damage caused by free radical damage by neutralization via neutralization mechanisms thus protecting from further harm caused by free radicals which could otherwise harm.

Carotenoids are natural lipid-soluble pigments found in fruits and vegetables. There are at least 600 of them; those most frequently found in humans include b-carotene, a-carotene, lycopene, alpha-carotene and beta-cryptoxanthin. These compounds serve as colorful pigments while playing key roles in our ocular system.

Lutein and zeaxanthin are two carotenoids classified as vitamin A that can be found in both retinal and lens tissues of the eye, acting as natural antioxidants to absorb damaging blue light rays and protect retinal tissue from damage. Furthermore, both may aid with cornea development.

A study conducted by the Netherlands Macular Screening Trial demonstrated that eating foods rich in beta-carotene and other carotenoids may lower one’s risk of advanced macular degeneration in their retinas. Over 1,300 participants over 70 who were at risk of AMD had significantly less advanced AMD than those in the lowest quintile for vegetable and fruit intake intake.

Dark green leafy vegetables such as kale, collard greens, turnip greens and spinach are an excellent source of lutein and zeaxanthin, along with other eye-healthy nutrients like vitamins A, choline, potassium and fiber. To maximize absorption of caroteoids from these foods, be sure to pair your consumption with some form of fat like olive oil, butter or margarine – otherwise your body might reject these precious vitamins! Other great sources are eggs, oranges kiwis fruit mangoes pumpkin and squash seeds and carrots!
