Various ways to prevent AMD
Macular degeneration can cause irreversible vision loss. Although it is nearly impossible to cure AMD, a variety of prevention measures are available to reduce the risk of AMD, especially for older people. Prevention is always better than treatment. Today, this eye disease is bothering a great number of patients across the world. It is really a tough condition and it is no easy to control its progression. In this sense, knowing some information about its prevention is overwhelmingly important.
Smokers are at a higher risk
Researchers from the University of Manchester said that smokers are up to four times more likely than non-smokers to develop AMD. For old people, it is a necessity to stop smoking. And this bad habit is actually also harmful to young people.
Diet containing plenty of vegetables helps prevent AMD
People consuming many vegetables rich in carotenoids are reported to have a 43% lower risk of developing AMD than those seldom eat these foods. These vegetables include dark, leafy greens, especially raw spinach, kale and collard greens. Older people can not absorb enough nutrients from diet alone, so that nutritional supplements including vitamins and minerals are useful to improve eye health.
What are healthy foods for AMD prevention?
Both Massachusetts Eye and Ear Infirmary and the University of Sydney have revealed that high consumption of fish reduces the risk of AMD. In addition, Harvard Medical School and the Massachusetts Eye and Ear Infirmary have demonstrated that AMD can be decreased by daily fruits and nuts consumption.
High glycemic index in refined foods cause a rapid increase in blood sugar and insulin release, which in turn increase the risk of AMD. So that the old should take low glycemic index foods, such as fruits, brown rice, grain breads, apple juice and carrot juice. High index foods including white bread, white rolls and donuts should be reduced.
What kind of nutritional formulas are recommended?
For people who are at high risks of developing advanced AMD, the Age-Related Eye Disease Study (AREDS) has found that nutrients play a key role in maintaining their current vision. The formula of nutrients recommended by AREDS includes vitamin C and E, beta-carotene, zinc oxide and cupric oxide. The study also shows that this formula can lower the risk of advanced AMD by 25%. But for smokers, AREDS recommends other nutritional formulas that exclude beta-carotene, which may increase the risk of lung cancer. Some researchers also oppose formulas with high-dose vitamin E, while others just eliminate its tiny risk.
Regular exercise is encouraged
The British Journal of Ophthalmology has conducted a study of 4000 old people, which showed that regular exercise such as walking can bring down the risk of AMD. What’s more, some eye care experts recommend daily eye exercises. They believe that these exercises can maintain or even improve people’s eyesight.
Some other aspects
Cholesterol built-up in blood vessels can inhibit blood flow, which is harmful for healthy eye tissue. In this case, cholesterol controlling can protect the old from AMD. Since high blood pressure is also indicated to have link to AMD, blood pressure controlling is necessary. Cumulative eye damage caused by overexposure to UV and HEV lights is estimated to arouse AMD, so that you’d better to wear sunglasses outdoors.
What if AMD is a reality without giving a notice?
Early detection and treatment of AMD can minimize the risk of vision loss caused by AMD. People between 45 and 60 are recommended to take an eye exam every two or three years, and people above 60 should take an exam every year.
