Their study of identical twins from the US World War II Twin Registry also observed that the more a person smoked, the higher their risk of developing macular degeneration. The study, "Smoking, Dietary Betaine, Methionine, and Vitamin D in Monozygotic Twins with Discordant Macular Degeneration: Epigenetic Implications" reported in the journal Ophthalmology on July 1, is the first to look at identical twin pairs in which one twin had early age-related macular degeneration (AMD), and the other had late stage AMD........ ]]> http://medicineworld.org/stories/lead/2-2011/age-related-macular-degeneration.html http://medicineworld.org/stories/lead/2-2011/age-related-macular-degeneration.html Fri, 22 Jul 2011 04:29:39 GMT A team of researchers, led by University of Kentucky ophthalmologist Dr. Jayakrishna Ambati, has discovered a molecular mechanism implicated in geographic atrophy, the major cause of untreatable blindness in the industrialized world.

A cataract is a blurring and impairment of vision as the eye's natural lens becomes cloudy. In addition to this blurriness, individuals with cataracts may have difficulty seeing at night, decreased experience of colors, and heightened sensitivity to bright conditions; they may often find themselves getting new prescriptions from their eye doctors. Cataracts can begin to develop when a person is 40 or 50, but most individuals do not experience serious, detrimental vision consequences as a result of cataracts before their 60s........ ]]> http://medicineworld.org/stories/lead/11-2010/gene-linked-to-the-spread-of-eye-melanoma..html http://medicineworld.org/stories/lead/11-2010/gene-linked-to-the-spread-of-eye-melanoma..html Fri, 22 Jul 2011 04:29:39 GMT Scientists at Washington University School of Medicine in St. Louis have identified a gene associated with the spread of eye melanoma. Eventhough more studies are needed, the scientists say the discovery is an important step in understanding why some tumors spread (metastasize) and others don't. They believe the findings could lead to more effective therapys........ ]]> http://medicineworld.org/stories/lead/10-2010/cataract-surgery-saves-lives.html http://medicineworld.org/stories/lead/10-2010/cataract-surgery-saves-lives.html Fri, 22 Jul 2011 04:29:39 GMT CHICAGOCataract surgery not only improves vision and quality of life for older people, but is also apparently a way to reduce the number of car crashes. The research will be presented today's at the Scientific Program of the 2010 American Academy of Ophthalmology (AAO) Middle East-Africa Council of Ophthalmology (MEACO) Joint Meeting. Cataract surgery not only improves vision and quality of life for older people, but is also apparently a way to reduce the number of car crashes. The research will be presented today's at the Scientific Program of the 2010 American Academy of Ophthalmology (AAO) Middle East-Africa Council of Ophthalmology (MEACO) Joint Meeting.

The study, which appears currently on-line in Eye, is thought to bethe first study to describe one-year outcomes of a prospective, double-masked, randomized clinical trial directly comparing bevacizumab to ranibizuamab. Last October, these same scientists published early, six month outcomes of the same study, which also failed to show a difference in efficacy between these two drugs for treating AMD........ ]]> http://medicineworld.org/stories/lead/5-2010/preventing-blindness.html http://medicineworld.org/stories/lead/5-2010/preventing-blindness.html Fri, 22 Jul 2011 04:29:39 GMT Automated Medical Diagnostics, a startup company based in Memphis, envisions its product helping to preserve the sight of millions of people who are at risk of vision loss from diabetic retinopathy. Using Telemedical Retinal Image Analysis and Diagnosis, a technology recently licensed by AMDx from the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee Health Science Center, patients can quickly be screened for the disease in their primary care doctor's office and other remote sites, permitting early detection and referral for diabetic retinopathy and other retinal diseases........ ]]> http://medicineworld.org/stories/lead/3-2010/anti-depressants-and-cataracts.html http://medicineworld.org/stories/lead/3-2010/anti-depressants-and-cataracts.html Fri, 22 Jul 2011 04:29:39 GMT Some anti-depressant drugs are linked to an increased chance of developing cataracts, as per a new statistical study by scientists at the University of British Columbia, Vancouver Coastal Health Research Institute and McGill University. The study, based on a database of more than 200,000 Quebec residents aged 65 and older, showed statistical relationships between a diagnosis of cataracts or cataract surgery and the class of drugs called selective serotonin reuptake inhibitors (SSRIs), as well as between cataracts and specific drugs within that class........ ]]> http://medicineworld.org/stories/lead/2-2010/green-tea-may-help-fight-glaucoma.html http://medicineworld.org/stories/lead/2-2010/green-tea-may-help-fight-glaucoma.html Fri, 22 Jul 2011 04:29:39 GMT Researchers have confirmed that the healthful substances found in green tea renowned for their powerful antioxidant and disease-fighting properties do penetrate into tissues of the eye. Their new report, the first documenting how the lens, retina, and other eye tissues absorb these substances, raises the possibility that green tea may protect against glaucoma and other common eye diseases. It appears in ACS's bi-weekly Journal of Agricultural and Food Chemistry....... ]]> http://medicineworld.org/stories/lead/1-2010/artificial-muscles-restore-ability-to-blink.html http://medicineworld.org/stories/lead/1-2010/artificial-muscles-restore-ability-to-blink.html Fri, 22 Jul 2011 04:29:39 GMT Surgeons from UC Davis Medical Center have demonstrated that artificial muscles can restore the ability of patients with facial paralysis to blink, a development that could benefit the thousands of people each year who no longer are able to close their eyelids due to combat-related injuries, stroke, nerve injury or facial surgery........ ]]> http://medicineworld.org/stories/lead/1-2010/eye-test-could-detect-alzheimers.html http://medicineworld.org/stories/lead/1-2010/eye-test-could-detect-alzheimers.html Fri, 22 Jul 2011 04:29:39 GMT A simple and inexpensive eye test could aid detection and diagnosis of major neurological diseases such as Alzheimer's at an earlier stage than is currently possible, as per new research by UCL scientists. The research, led by Professors Francesca Cordeiro and Stephen Moss and published recently in Cell Death and Disease, demonstrates a new technique that enables retinal, and therefore brain cell death, to be directly measured in real time. The method, demonstrated in an animal model, could not only refine diagnosis of neurodegenerative disorders and help track disease progress; it could also aid the evaluation and development of new therapys........ ]]> http://medicineworld.org/stories/lead/1-2010/its-never-too-late-to-quit-smoking.html http://medicineworld.org/stories/lead/1-2010/its-never-too-late-to-quit-smoking.html Fri, 22 Jul 2011 04:29:39 GMT Need a little extra incentive to kick the habit? Just in time for New Year's resolutions, a UCLA study finds that even after age 80, smoking continues to increase one's risk for age-related macular degeneration (AMD), the leading cause of blindness in Americans over 65.

Dr. Peter Hersh, the study doctor, will perform the procedures. The investigational AcuFocus Corneal Inlay (ACI) is intended to improve near vision in patients with presbyopia, which is the loss of near vision, and reduce dependency on reading glasses. Qualified participants will receive the procedure at no charge........ ]]>
