There are two main types of advanced AMD - dry and wet. The former makes up over 90% of cases and, the less common wet form makes up the remaining 10%. <br />CAUSE OF MACULAR DEGENERATION <br />The cause of dry macular degeneration is the formation of deposits called drusen on the macula. Drusen are fairly common in individuals over 50 years of age and do not cause any visual impairment when found in small numbers. However, when they become larger and more extensive they start to adversely affect vision. <br />Drusen are yellowish accretions of lipoproteins in the lining of the retina. The cause of AMD and the reasons that drusen form is not entirely clear but there is a relationship with their formation and those of cholesterol deposits in arteries and other parts of the body. <br />RISK FACTORS FOR MACULAR DEGENERATION: <br />OXIDATIVE STRESS: This state is associated with free radical overload and antioxidant deficiency that occurs more frequently with aging. There is convincing evidence that oxidative stress is the underlying cause of AMD as oxidative stress increases with age and is associated with several diseases like diabetes <a href="http://www.airmaxclub.net/nike-air-max-lebron," target="_blank">http://www.airmaxclub.net/nike-air-max-lebron,</a> obesity and others. <br />INFLAMMATION: An inflammatory process is also involved in the formation of drusen and both the dry and wet types of AMD. <br />AGE: The older you are the greater your risk of developing AMD. <br />SMOKING: Smokers have a higher incidence of AMD. <br />GENETIC PREDISPOSITION: Certain genes have been identified that place some people at increased risk for AMD. <br />OBESITY: Overweight is associated with oxidative stress and increased risk for AMD. <br />BLOOD PRESSURE AND CHOLESTEROL: Individuals with hypertension and abnormal blood lipid levels have an increased risk for AMD. <br />PREVENTION AND TREATMENT OF AMD WITH ANTIOXIDANTS <br />Several very large studies have shown conclusively that those individuals who eat a diet rich in antioxidants lower their risk of developing AMD. <br />Two of the most comprehensive of these are the AGE RELATED EYE DISEASE STUDY and the BLUE MOUNTAINS EYE STUDY both of which monitored the diets and examined the eyes of over 3500 participants for at least eight years. <br />These two studies confirmed earlier research that showed how antioxidants can slow the progression of AMD by up to 35%! <br />BEWARE THE WRONG ANTIOXIDANTS! <br />However there were a few important findings that should be noted. Although these and other studies have provided conclusive evidence that a diet high in antioxidants can protect against the development of macular degeneration, the Blue Mountains Eye Study found that an intake of the antioxidant, ?-carotene in high doses actually increased the risk of developing AMD. High doses of ?-carotene have also been shown to increase the risk of cancer in smokers. <br />Another study conducted by the Massachusetts Eye and Ear Infirmary showed that those who ate significant quantities of foods that were rich in antioxidants were protected against both wet and dry forms of AMD; even though they did not take antioxidant vitamin supplements. <br />Taken together these studies make two important points. The first is that we need a regular, intake of safe <a href="http://www.airmaxclub.net/%20nike-air-max-kids," target="_blank">http://www.airmaxclub.net/%20nike-air-max-kids,</a> effective antioxidants to help prevent the onset and/or progression of AMD. Secondly, that it is better to take the antioxidants in their natural form rather than high doses of individual antioxidants (like ?-carotene) that may have harmful side effects. <br />SPICES THE BEST SOURCE OF EFFECTIVE ANTIOXIDANTS <br />In this respect it is worth noting that spices have the highest antioxidant activity of all food groups (American Journal of Clinical Nutrition 2006). <br />They are the best source of the wide variety of antioxidant compounds that are necessary to help counter the effect</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
