Progressive degeneration of photoreceptors—the rods and cones of the eyes—causes blinding diseases such as retinitis pigmentosa and age-related macular degeneration. While there are currently no available treatments to reverse this degeneration, a newly developed compound allows other cells in the eye to act like photoreceptors. As described in a study appearing in the February 19 issue of the Cell Press journal Neuron, the compound may be a potential drug candidate for treating patients...

(Ivanhoe Newswire) -- Precision tinted lenses have been used widely to reduce visual perceptual distortions in poor readers, and are increasingly used for migraine sufferers, but until now the science behind these effects has been unclear. Researchers have now pinpointed the neurological basis for these visual remedies. The new research shows how colored glasses tuned to each migraine sufferer work by normalizing activity in the brain. The researchers saw specific abnormal brain activity...

Precision tinted lenses have been used widely to reduce visual perceptual distortions in poor readers, and are increasingly used for migraine sufferers, but until now the science behind these effects has been unclear. Now research published in the journal Cephalalgia, published by SAGE, uses functional magnetic resonance imaging (fMRI) for the first time to suggest a neurological basis for these visual remedies. The new research shows how coloured glasses tuned to each migraine sufferer work...

National Headache Foundation Launches 'War Veterans Health Resource Initiative' to Help Ease Transition Back to Civilian Life CHICAGO, Nov. 9, 2010 /PRNewswire-USNewswire/ -- Studies have shown that soldiers returning home from Iraq and Afghanistan have been found to have nearly double the rates of migraine compared to the general population, as well as higher incidences of Post-Traumatic Stress Disorder (PTSD), depression and anxiety. Now, veterans returning from active duty with these...

Extreme light sensitivity in blind patients helps researchers identify a new visual pathway for photophobia during migraines Ask anyone who suffers from migraine headaches what they do when they're having an attack, and you're likely to hear "go into a dark room." And although it's long been known that light makes migraines worse, the reason why has been unclear. Now scientists at Beth Israel Deaconess Medical Center (BIDMC) have identified a new visual pathway that underlies sensitivity to...

Several scientific studies over the last 30 years have looked at the role of ultraviolet (UV) light in triggering the autoimmune disease lupus. UV light is invisible radiation from the sun and is also emitted from fluorescent lights. As many as half of the estimated 1.5 million Americans living with lupus experience abnormal light sensitivity, or "photosensitivity." People who are photosensitive develop a skin rash as a result of unusual reaction to sunlight or artificial light containing UV...

WASHINGTON (Reuters) - As many as 60,000 people a year die from too much sun, mostly from malignant skin cancer, the World Health Organization reported on Wednesday. It found that 48,000 deaths every year are caused by malignant melanomas, and 12,000 by other kinds of skin cancer. About 90 percent of such cancers are caused by ultraviolet light from the sun. Radiation from the sun also causes often serious sunburn, skin aging, eye cataracts, pterygium -- a fleshy growth on the...
