A new study finds that certain changes in blood vessels in the eye's retina can be an early warning that a person is at increased risk for glaucoma, an eye disease that slowly robs people of their peripheral vision. Using diagnostic photos and other data from the Australian Blue Mountains Eye Study, the researchers showed that patients who had abnormally narrow retinal arteries when the study beg

Researchers Identify an Early Predictor for Glaucoma
Posted by Praveen (#2) 4031 days ago (Editorial)Glucosamine Linked to Increased Intraocular Pressure
Posted by Praveen (#2) 4031 days ago (Editorial)
Glucosamine supplementation was linked to significant, reversible increases in intraocular pressure (IOP) in a small, retrospective study published online May 23 in JAMA Ophthalmology. However, the investigators, led by Ryan K. Murphy, DO, from the University of New England College of Osteopathic Medicine, Biddeford, Maine, and colleagues, could not exclude the potential for permanent damage. "Fr
Novel Disease in Songbirds Demonstrates Evolution in the Blink of an Eye
Posted by Praveen (#2) 4031 days ago (Editorial)
A novel disease in songbirds has rapidly evolved to become more harmful to its host on at least two separate occasions in just two decades, according to a new study. The research provides a real-life model to help understand how diseases that threaten humans can be expected to change in virulence as they emerge.

The Crucial Years for Protecting Your Eye Health
Posted by Praveen (#2) 4031 days ago (Editorial)
Aging eyes bring more than crow's feet and wrinkles. It's what you can't see—the health of your eyes—that is the bigger concern, doctors say. By the age of 40, many people may begin coping with vision problems they didn't have before. These might include dry eyes and presbyopia, or an inability to focus on objects that are close up, and can leave people feeling fatigued and headachy by the end of
Treatment for Glaucoma May Lead To Droopy Eyelids
Posted by Praveen (#2) 4031 days ago (Editorial)
Prostaglandin analogues (PGAs), drugs which lower intraocular pressure, are often the first line of treatment for people with glaucoma, but their use is not without risks. PGAs have long been associated with blurred vision, dryness, changes in eye color and other side effects. Now a new study has found that these drugs also cause upper and lower eyelid drooping and other issues that can interfere
2 Novel Treatments for Retinitis Pigmentosa Move Closer To Clinical Trials
Posted by Praveen (#2) 4034 days ago (Editorial)
Two recent experimental treatments - one involving skin-derived induced pluripotent stem (iPS) cell grafts, the other gene therapy - have been shown to produce long-term improvement in visual function in mouse models of retinitis pigmentosa (RP), according to the Columbia University Medical Center (CUMC) scientists who led the studies. At present, there is no cure for RP, the most common form of

Eye May Be Key to More Accurate ADHD Diagnosis
Posted by Praveen (#2) 4034 days ago (Editorial)
Examining the retina may aid in the diagnosis of attention-deficit/hyperactivity disorder (ADHD), new research suggests. A small study by investigators at Albert-Ludwigs University of Freiburg, Germany, showed that patients with ADHD displayed significantly elevated "background noise" on a pattern electroretinogram (PERG) compared with their healthy peers. Altered visual signal processing may be
