Today, macular degeneration is the leading cause of irreversible
blindness and by the year 2020, an estimated 7.5 million Americans will suffer significant
vision loss due to macular degeneration. Although there is no effective treatment yet,
natural remedies can go a long way in preventing the disease from progressing to the point
of vision loss.
How do you know if you have the disease? Macular degeneration is the slow deterioration of the cells in the macula, a tiny yellowish area near the center of the retina where vision is most acute. This deterioration therefore affects your central vision, the very vision you use for reading, writing, driving, and identifying faces. When you have macular degeneration, straight lines become crooked, distinct shapes are blurry, lines become wavy, and there is a fog in the center of your vision. However your peripheral vision is not affected. There are two types of macular degeneration. Ninety percent of people with macular degeneration have the dry type, in which small yellow spots called drusen form underneath the macula. The drusen slowly break down the cells in the macula, causing distorted vision. Dry macular egeneration can progress to the second, more severe type, called wet macular degeneration. In the wet type of macular degeneration, new abnormal blood vessels begin to grow toward the macula, these new blood vessels may leak blood and fluid that further deteriorate the macula, causing rapid and severe vision loss.
At the present time, there is no effective treatment. Some causes of wet macular degeneration are treated with laser surgery, but the treatment itself may not effectively seal up a leaky blood vessel without at the same time permanently destroying retinal nerve fibers that pass through the area. According to the National Eye Institute, laser treatment can actually worsen vision and it is at least a year after surgery before any possible benefits may be realized. As always, prevention is the best medicine. Since less than one per cent of those with macular degeneration have progressed to the point of legal blindness, most are in a position to benefit greatly from prevention.
Although conventional eye doctors offer no effective treatment for macular degeneration at the present time, complementary medicine offers a way to help prevent and treat this condition.
The two most important nutrients are lutein and zeaxanthin.
What does lutein and zeaxanthin do for our eyes? Lutein and zeaxanthin supplements are best taken separately from beta- carotene supplements because they compete for absorption. Also, they need fat to absorb well, so take them with food or a small amount of oil. The best time to take lutein is at night before you go to bed. Other important nutrients for the treatment of macular degeneration include the following:
Zinc is found in high concentrations in the eye, especially the retina and its underlying tissues. Zinc helps bind the protective pigment layer of the retina to the underlying tissue. Below are some other considerations:
Sunglasses should be worn when outside in bright sunlight. They should be 100 percent UVA and UVB blocking lenses with wrap around sides. Wear along with a 3 inch brim hat. There are hundreds of research studies that show that what one eats can have a significant effect on health of the macula. Unfortunately, once a person has macular degeneration, a healthy diet is not enough to prevent this disease from worsening. The levels of nutrients found in foods and in typical multivitamins are not levels that significantly impact on the progression of the disease. However, therapeutic doses of certain supplements have been shown not only to reduce the risk of macular degeneration, but also to improve vision in people who already have the disease. Since it can take up to nine months for retinal cells to rejuvenate, any nutritional program for macular degeneration should be taken for a minimum of nine months.
