April 17, 2011 - Researchers may have found a way to prevent an age-related eye disease from getting worse. Dry and Wet are the two forms of AMD, or age-related macular degeneration. The dry form causes blurring or a blind spot in your vision, but not total blindness. Wet AMD is not as common as dry AMD but can lead total blindness. The new research has pinpointed a part of the immune system which often causes dry AMD to evolve into the more serious Wet AMD. Researchers hope this leads to new treatments for age-related macular degeneration.
Also, a new study says a widely used test to measure electrical activity in the heart may help identify elderly people at risk of a heart attack. The study published in the Journal of the American Medical Association, rekindles a debate over the value of such tests in people without chest pain or other symptoms. In the new study, 36 percent of the patients were diagnosed with either major or minor abnormalities through an EKG. The results roughly suggested that if 100 patients without abnormalities were followed for 10 years, 17 would suffer a heart attack, heart-related death or hospitalization for heart disease, compared with 29 out of 100 with minor abnormalities and 32 with major ones.
