October 10, 2012 - People who take statins to protect their heart may also be protecting their vision. Glaucoma affects more than 2.7 million Americans age 40 and older . If untreated, glaucoma causes vision loss or blindness by damaging the eye's optic nerve. A study from the University of Michigan finds patients on statins are eight percent less likely to develop glaucoma. Several of the study's findings suggest that statin use may be most important before glaucoma is diagnosed, or in the early stages of the disease. Statins lower cholesterol and researchers believe they may help improve blood flow to the eyes. The study, which is the largest to date on the topic, is published in the October issue of Ophthalmology.
Also, a virus may be able to stop an aggressive form of breast cancer. Doctors at Stanford added a tumor fighting protein to a harmless virus and gave it to mice with triple negative breast cancer. They found the virus was able to infect cancer cells and deliver the protein killing tumors. About 20 percent of breast cancer cases in the US are triple negative. Researchers are now planning tests on people.
