Krishna Ramanujan, Cornell University Coffee drinkers, rejoice! Aside from java’s energy jolt, food scientists say you may reap another health benefit from a daily cup of joe: prevention of deteriorating eyesight and possible blindness from retinal degeneration due to glaucoma, aging and diabetes. Raw coffee is, on average, just 1 percent caffeine, but it contains 7 to 9 percent chlorogenic acid (CLA), a strong antioxidant that prevents retinal degeneration in mice, according to a...

Indiana University researchers have detected new early-warning signs of the potential loss of sight associated with diabetes. This discovery could have far-reaching implications for the diagnosis and treatment of diabetic retinopathy, potentially impacting the care of over 25 million Americans. "We had not expected to see such striking changes to the retinas at such early stages," said Ann Elsner, professor and associate dean in the IU School of Optometry and lead author of the study. "We...

Patients suffering from diabetic retinopathy learn how to control their diabetes and how to manage their disease at Specialty Retina Center of Boca Raton. The surgeons at Specialty Retina Center expand their reach across South Florida, educating patients on disease prevention. Boca Raton, FL (PRWEB) August 31, 2013 Local surgeons are educating Boca Raton residents on the importance of regular eye exams and the importance of regular check-ups. Patients with diabetes need to be vigilant...

A new therapeutic approach to diabetes that combines insulin and an inhibitor of the epidermal growth factor (EGF) betacellulin could limit the progression of diabetic macular edema (DME), Cleveland Clinic researcher Bela Anand-Apte, MD, PhD, said at the American Society for Cell Biology Annual Meeting, on Dec. 17 in San Francisco. The study, conducted with insulin-dependent diabetic mice, showed that by thwarting "cross-talk" between insulin and betacellulin (BTC), which promotes the...

Blood Vessel Protein Research Promising For Controlling 'Blood-brain Barrier'

Johns Hopkins Medicine Experiments also suggest approaches to treating blood vessel disorders in the eye Working with mice, Johns Hopkins researchers have shed light on the activity of a protein pair found in cells that form the walls of blood vessels in the brain and retina, experiments that could lead to therapeutic control of the blood-brain barrier and of blood vessel growth in the eye. Their work reveals a dual role for the protein pair, called Norrin/Frizzled-4, in managing the...

Hypertension frequently coexists in patients with diabetes. A new University of Georgia study shows why the co-morbid conditions can result in impaired vision. "Results showed early signals of cell death in eyes from diabetic animals within the first six weeks of elevated blood pressure. Later, the tiny blood vessels around the optic nerve that nourish the retina and affect visual processing showed signs of decay as early as 10 weeks after diabetic animals develop hypertension," said Azza...

(Ivanhoe Newswire) — Look into your brain! A new study reveals people with mild vascular disease are more likely to have problems with memory skills and thinking. Damage to the retina is called retinopathy. Researchers found people with mild vascular disease with retinopathy are more likely to have problems with thinking and memory skills because they may also have vascular disease in the brain. In the study, the damage was mild enough to not cause significant symptoms. The study...

The inhibition or removal of an enzyme may prevent or treat ischemic retinopathy by stalling growth of unwanted vessels in the retina, Medical College of Georgia researchers say. Ischemic retinopathy is characterized by uncontrolled formation of new blood vessels in the retina, and is seen in diseases such as diabetic retinopathy and retinopathy of prematurity. While this blood vessel formation, called neovascularization, can benefit ischemic heart disease and wound healing, it is bad in the...

Nutriceutical restores lost sight While age-related vision loss of catastrophic proportions is predicted in coming decades, rising from 17 million patients today to 55 million by the year 2050, it's possible this catastrophe could be averted and lost vision even restored using molecular medicine. These are the words of Stuart Richer, OD, PhD, speaking at the 10th annual meeting and International Conference on Recent Trends in Therapeutic Advancement of Free Radical Science, in Chennai, India...

One drug's startling ability to restore retinal health in the eyes of diabetic mice has researchers wanting to learn more about how it works and whether it might do the same for people. "We want to know if this drug has the potential to block the visual devastation that can occur with diabetes," said Dr. Sylvia Smith, retinal cell biologist and co-director of the Vision Discovery Institute at the Medical College of Georgia. "That means we need to know more about how and when it is...
