cataracts
As many as 10 million people around the world suffer from cataracts.
Waterford City, Ireland, October 26, 2009 -- Results of an important new study show that implantation of blue light-filtering intraocular lens (IOLs) at the time of cataract surgery increases a nu
A kidney condition that can arise in children and was until recently believed to disappear after puberty may persist into adulthood and cause significant long-term complications, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN).
By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale -- and the findings look promising.
PORTLAND, Ore. -- Three drugs that reduce a woman's chance of getting breast cancer also have been shown to cause adverse effects, according to a new report from the Agency for Healthcare Research and Quality (AHRQ), U.S. Department of Health & Human Services.
Injecting the eye with the corticosteroid triamcinolone appears effective in improving the vision of some patients with retinal vein occlusion, an important cause of vision loss that results from blockages in the blood vessels in the retina, according to two reports in the September issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
Rockville, MD -- By 2020, 1.4 million Nigerians over age 40 will lose their sight, and the vast majority of the causes are either preventable or treatable, according to the Nigeria National Blindness and Visual Impairment Study Group.
It seems like common sense that an information leaflet for vision loss would have large print and appropriate contrast, but that's not the case a new study done at the University of Alberta has found.
CLEVELAND -- July 30, 2009 -- Bing-Cheng Wang, Ph.D., Case Western Reserve University School of Medicine professor of pharmacology and senior staff scientist at MetroHealth Medical Center, and Sudha K. Iyengar, Ph.D.
NEW YORK (June 4, 2009) -- NewYork-Presbyterian Hospital/Columbia University Medical Center physician-scientists presented new research at the 2009 American Transplant Congress in Boston, May 30 to June 3. Topics included minimizing steroid exposure for liver transplant patients with hepatitis C; hypothermic machine perfusion vs.
There’s another reason to dust off those running shoes. Vigorous exercise may help prevent vision loss, according to a pair of studies from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory.
Results from a new study show that lifetime lead exposure may increase the risk of developing cataracts. Researchers found that men with high levels of lead in the tibia, the larger of the two leg bones below the knee, had a 2.5-fold increased risk for cataract, the leading cause of blindness and visual impairment.
Beer drinkers can toast the news that their favourite beverage possesses the same benefits as red wine, the alcohol long celebrated for its antioxidant properties. Researchers at The University of Western Ontario have found one drink of beer or wine provides equivalent increases in plasma antioxidant activity, which helps prevent the oxidization of blood plasma by toxic free radicals that trigger many aging diseases, such as cancer, diabetes, heart disease and cataracts. Biochemistry and kinesiology professor John Trevithick, one of the lead researchers and a long-time expert on the role of antioxidants in human health, says, ''We were very surprised one drink of beer or stout contributed an equal amount of antioxidant benefit as wine, especially since red wine contains about 20 times the amount of polyphenols as beer.''
For most people, the need to wear eyeglasses to read is an inevitable part of aging. The eye's natural lens hardens and loses its ability to change shape, making it more difficult to focus, especially when reading up close. With age also comes the development of cataracts or clouding of the eye's natural lens. Intraocular lenses (IOLs) traditionally have been used to replace the eye's natural lens after its removal during cataract surgery. However, with the traditional IOLs, most patients still needed to wear glasses for reading and using the computer. This, however, may be changing.
Researchers have discovered a gene responsible for the onset of aging, including age-related disorders such as infertility, reproductive problems and cataracts. This research, conducted in genetically modified mice, is promising in helping physicians understand and treat the same disorders in humans. The discoveries came as the result of general investigations into possible genetic causes of cancer. In this case, it was discovered that this particular gene, called BubR1, governs production of a protein that modulates physical aging. The mice studied lacked normal levels of that protein and began to age prematurely.
