Working memory (also known as short term memory) is our ability to keep a small amount of information active in our mind. view more (2009-02-23)
Learned motor programs directly influence the visual perception of movements
When novel movements are learned-for example, in sports-visual and motor learning take place simultaneously. view more (2006-01-10)
Noncorrectable vision problems associated with shorter lifespan in older adults
Visual problems that cannot be corrected are associated with increased risk of death among individuals between the ages of 49 and 74, and all visual impairments may be associated with the risk of death in older adults. view more (2009-10-13)

Blindsight is a phenomenon in which patients with damage in the primary visual cortex of the brain can tell where an object is although they claim they cannot see it. view more (2008-10-15)
Sound adds speed to visual perception
The traditional view of individual brain areas involved in perception of different sensory stimuli-i.e., one brain region involved in hearing and another involved in seeing-has been thrown into doubt in recent years. view more (2008-08-12)
Read My Lips: Using Multiple Senses in Speech Perception
When someone speaks to you, do you see what they are saying? We tend to think of speech as being something we hear, but recent studies suggest that we use a variety of senses for speech perception - that the brain treats speech as something we hear, see and even feel. view more (2009-02-12)
Reorganization of brain area for vision after stroke: May yield new treatments for brain injury
New evidence from a patient shows that the area of the brain that processes visual inputs can reorganize after an injury caused by stroke. view more (2007-09-05)
UK Childhood Blindness More Common Than Previously Thought (p 1359)
Increased ethnic diversity and greater survival of low-birthweight babies is contributing to a higher proportion of children becoming visually impaired or blind, according to authors of a UK study in this week's issue of THE LANCET. The study also highlights how childhood visual impairment is associated with lower socio-economic status. The... view more... (2003-10-22)
Brain's timing linked with timescales of the natural visual world
Researchers have long attempted to unravel the cryptic code used by the neurons of the brain to represent our visual world. By studying the way the brain rapidly and precisely encodes natural visual events that occur on a slower timescale, a team of Harvard bioengineers and brain scientists from the State University of New York have moved one step... view more...

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)
Fluctuating eye pressure associated with visual field deterioration in glaucoma patients
Fluctuations in eye pressure may be associated with a decreasing peripheral field of vision in patients with glaucoma, even if their eye pressure remains low overall. view more (2007-08-14)
Vision loss more common in people with diabetes
Visual impairment appears to be more common in people with diabetes than in those without the disease, according to a report in the October issue of Archives of Ophthalmology, one of the JAMA/Archives journals. view more (2008-10-14)
Low birth weight babies with reduced occipital regional volumes at higher risk for visual impairment
Preterm infants with smaller occipital brain volumes are more likely to experience impaired visual function in early childhood according to a study published in the August 2006 issue of Investigative Ophthalmology & Visual Science (IOVS). view more (2006-08-30)
Epilepsy drug causes eye problems in over 40 per cent of cases
Vigabatrin, a drug used to treat epilepsy, causes eye problems in over 40 per cent of those prescribed it, shows a study in the Journal of Neurology Neurosurgery and Psychiatry. Vigabatrin was licensed in the UK in 1989 and was the first anti-epileptic drug to come on to the marked since the 1970s. Although effective, it has been associated with... view more... (2002-08-20)

An innovative course designed for health professionals working with people facing the trauma of sight loss has won the Yorkshire Times Healthcare Industry Course of the Year Award. The Royal National Institute of the Blind (RNIB)/City University`s Department of Optometry and Visual Science Support Studies course is aimed at staff working in eye... view more... (2002-06-27)
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 predicts 40 percent increase in blindness in Nigeria by 2020
By 2020, 1.4 million Nigerians over age 40 will lose their sight, and the vast majority of the causes are either preventable or treatable, according to the Nigeria National Blindness and Visual Impairment Study Group. view more (2009-09-09)
Visual impairment associated with increased mortality risk
Individuals age 49 and older with cataract and those age 49 to 74 years with age-related macular degeneration appear to have higher mortality rates over an 11-year period than those without such visual impairments. view more (2007-07-10)
New study shows those blinded by brain injury may still 'see'
Except in clumsy moments, we rarely knock over the box of cereal or glass of orange juice as we reach for our morning cup of coffee. New research at The University of Western Ontario has helped unlock the mystery of how our brain allows us to avoid these undesired objects. view more (2009-09-03)
