Vision and hearing loss often occur together in older age
Older adults with vision loss may be more likely to also have hearing loss, and the opposite appears true as well. view more (2006-10-10)
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)
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)
Age-related vision problems may be associated with cognitive impairment
Older patients with advanced age-related macular degeneration and reduced vision may be more likely to also have cognitive impairment, or problems with thinking, learning and memory. view more (2006-04-11)
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)

Cerebrospinal Fluid Restores Vision
A new method for visual impairment treatment has been discovered by researchers of the Institute of Human Brain, Russian Academy of Sciences. The patients suffering from visual impairment can be helped if a healthy donor's cerebrospinal fluid is introduced to the parent's vertebral canal - this method is called liquortransfusion. Physiologists... view more... (2004-11-01)
Hearing loss in children is higher than previously thought
Far more children in the United Kingdom suffer with permanent hearing impairment by the age of 9 years than previously estimated, find researchers in this week's BMJ. This has important implications for co-ordinating services for deaf and hearing impaired children. Postal questionnaires were used to identify over 17,000 children throughout the UK... view more...

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)
Deaf-blind woman deafer than deaf-blind man
Dutch researcher Ronald Pennings has found new clinical and genetic characteristics for two different inherited syndromes that cause deaf-blindness. One of the two syndromes appears to cause more hearing impairment in women than in men. Pennings investigated Wolfram syndrome and Usher syndrome. These are two inherited syndromes that cause both... view more... (2004-05-07)
Researchers map links between size of hippocampus and progression to Alzheimer's dementia
UCLA researchers sought to test the theory that the hippocampus - the area of the brain that processes memory - is smaller in patients with mild cognitive impairment who develop into Alzheimer's dementia, and that it is larger in patients with mild cognitive impairment who experience cognitive stability or improvement. view more (2006-05-09)
Anticholinergic drugs linked to mental impairment in elderly people
Anticholinergic drugs may lead to mild cognitive (mental) impairment in elderly people, finds a study published online by the BMJ today. view more (2006-02-01)
Pioneers in field of functional genomics work toward gene therapy for vision defects
"Primates and humans have three photoreceptors and can only see four basic colors, red, green, blue and yellow," says Jay Neitz, Ph.D. "Birds, fish and reptiles have four photoreceptors, allowing them to see things we cannot. They must see an entire dimension of color, including ultraviolet, infrared and all the combinations... view more... (2006-12-12)
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)
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)
Cognitive problems associated with diabetes duration and severity
Individuals with mild cognitive impairment appear more likely to have earlier onset, longer duration and greater severity of diabetes, according to a report in the August issue of Archives of Neurology, one of the JAMA/Archives journals. view more (2008-08-12)
Refractive errors affect vision for half of American adults
About half of U.S. adults age 20 and older have refractive errors, or eye problems that result in less than 20/20 vision, according to a report in the August issue of Archives of Ophthalmology, one of the JAMA/Archives journals. view more (2008-08-12)
Innovative 3D-imaging technique captures brain damage linked to Alzheimer's disease
Using an advanced three-dimensional mapping technique developed by UCLA researchers, the team analyzed magnetic resonance imaging data from 24 patients with amnestic mild cognitive impairment (MCI) and 25 others with mild Alzheimer's disease. view more (2007-10-12)
Post-mortem brain studies reveal features of mild cognitive impairment
The brains of patients with mild cognitive impairment display pathologic features that appear to place them at an intermediate stage between normal aging and Alzheimer's disease, although some patients with mild cognitive impairment develop other types of dementia. view more (2006-05-09)
