The ability to retain memory about the details of a natural scene is unaffected by the distraction of another activity and this information is retained in "working memory". view more (2006-01-20)
Impaired vision common in US
A new report estimates that approximately 14 million people aged 12 years and older in the U.S. have vision impairment, of which more than 80 percent could be improved with the use of corrective lenses. view more (2006-05-10)
Study Highlights Need For UK Childhood Screening For Amblyopia (pp 597, 621)
Authors of a study in this week's issue of THE LANCET highlight how the risk of visual loss in the normal eye for individuals with one lazy eye (amblyopia) is greater than previously thought, strengthening the need for effective screening programmes to detect amblyopia in early childhood. Monocular amblyopia occurs in at least 1% of individuals... view more... (2002-08-21)

Some Short-term Memories Die Suddenly, No Fading
The human brain stores some kinds of memories for a lifetime. But when our eyes are open and looking at things, our gray matter also creates temporary memories that help us process complex tasks during the few seconds these visual memories exist. view more (2009-04-29)

Vision restoration therapy shown to improve brain activity in brain injured patients
Columbia University Medical Center researchers have demonstrated using functional magnetic resonance imaging (fMRI), that brain activity was increased in stroke and traumatic brain injury survivors who underwent Vision Restoration Therapy (VRT), a rehabilitative treatment that helps these patients recover lost vision. view more (2007-08-14)
Dual-imaging technique useful before -- and during -- brain surgery
Brain specialists associated with the Neuroscience Institute at the University of Cincinnati (UC) and University Hospital say the ability to incorporate-in real time-two high-tech imaging tools into the operating room can improve the functional abilities of patients who undergo brain surgery. view more (2007-06-11)

Early vision screening associated with better eyesight in children with amblyopia
Children who screen positive for amblyopia, reduced vision in one eye, before age 2 appear to have better visual outcomes than those whose vision problems are detected during screenings between ages 2 and 4. view more (2008-04-15)
NIST math technique opens clearer window on universe
A fast, efficient image enhancement technique developed at the National Institute of Standards and Technology (NIST) and originally applied to improving monochrome microscope images has proved itself equally effective at the other end of the scale- sharpening details on color images of distant galaxies produced by the Hubble Space Telescope. view more (2006-12-11)

Penn researchers find treatment for MS also reduces vision loss in MS patients
According to a study that appears in the April 17 issue of Neurology, researchers at the University of Pennsylvania School of Medicine have found that natalizumab (TYSABRI®) - a drug that slows disability and reduces relapse rates in patients with multiple sclerosis (MS) - also reduces vision loss in patients with relapsing MS. view more (2007-04-17)
