AMD discovery: New hope for treatment of vision loss
Scientists have won a major battle in the fight against age-related macular degeneration, or AMD, a blinding eye disease that affects millions of people. An international team, led by researchers at Sainte-Justine Hospital and the Université de Montréal, has identified the deficient receptor that causes the dry form of AMD. view more (2008-02-21)
Warning: Expert at UH adds obesity to side effects of lead exposure
Scientists know exposure to low levels of lead can result in learning disabilities, hearing loss, language impairments and vision loss, but a newly discovered side effect may be adult-onset obesity in men, according to a University of Houston professor. view more (2008-02-21)
Role identified for glaucoma gene and related signaling pathway
Researchers have found that a gene and a related signaling pathway play a role in the development of glaucoma, which is a common cause of visual impairment and blindness worldwide. view more (2008-02-15)
New cataract gene discovered
The international team of researchers was able to identify the location and defect in the coding region of the gene through analysis of genetic material (DNA) from members of a large Swiss family, the majority of whom suffered from autosomal dominant juvenile cataract. view more (2008-02-15)
Older whites more likely to have signs of future eye disease than blacks
White individuals older than 65 are more likely than black individuals to have characteristics that indicate they will develop more advanced forms of the eye disease age-related macular degeneration (AMD). view more (2008-02-12)
National survey shows minority children experience multiple disparities in health care
There is a lack of equity in health care for minority children in America, according to data gathered in a nationwide survey and analyzed by a UT Southwestern Medical Center researcher. view more (2008-02-06)
MIT: Computer vision may not be as good as thought
For years, scientists have been trying to teach computers how to see like humans, and recent research has seemed to show computers making progress in recognizing visual objects. A new MIT study, however, cautions that this apparent success may be misleading because the tests being used are inadvertently stacked in favor of computers. view more (2008-01-25)
Face facts: People don't stand out in crowds
Why is it difficult to pick out even a familiar face in a crowd? We all experience this, but the phenomenon has been poorly understood until now. view more (2008-01-22)
Study discovers secret of Scottish sheep evolution
Researchers from the University of Sheffield, as part of an international team, have discovered the secret of why dark sheep on a remote Scottish Island are mysteriously declining, seemingly contradicting Darwin's evolutionary theory. view more (2008-01-18)
Technique enhances digital television viewing for visually-impaired
Scientists at Schepens Eye Research Institute have found that people with low vision can improve their ability to see and enjoy television with a new technique that allows them to enhance the contrast of images of people and objects of interest on their digital televisions. view more (2008-01-16)
Contact lenses purchased over Internet may place individuals at risk for harmful eyecare practices
Purchasing contact lenses online may save consumers time, but the process could cause more problems in the long run, according to a new study reported in the January issue of Optometry: Journal of the American Optometric Association. view more (2008-01-07)
LASIK works well, according to long-term study of highly myopic patients
Laser surgery to correct vision problems has been in use since the early 1990s. Photorefractive Keratotomy (PRK) is typically used to correct low to moderate myopia, while laser in-situ keratomileusis (LASIK) is preferred for high myopia corrections. view more (2007-12-28)
Color sudoku puzzle demonstrates new vision for computing
Researchers at the University of Warwick's Department of Computer Science have developed a colour based Sudoku Puzzle that will help Sudoku players solve traditional Sudoku puzzles but also helps demonstrate the potential benefits of a radical new vision for computing. view more (2007-12-18)
Building disease-beating wheat
Disease resistance genes from three different grass species have been combined in the world's first 'trigenomic' chromosome, which can now be used to breed disease resistant wheat varieties. view more (2007-12-13)
New treatment for age-related macular degeneration within sight
With 8 million people at high risk for advanced age-related macular degeneration, researchers from Harvard and Japan discovered that the experimental drug, endostatin, may be the cure. view more (2007-11-30)
USC study -- largest of its kind -- finds older children more likely to develop vision disorders
In a study of more than 6,000 Los Angeles-area children - the largest study of its kind - researchers at the Keck School of Medicine of the University of Southern California (USC) found that both strabismus (commonly known as cross-eyed or wall-eyed) and amblyopia (often referred to as lazy eye) were more prevalent in older children than in... view more...

Immune cell age plays role in retinal damage in age-related macular degeneration
Studying a mouse model of age-related macular degeneration, the leading cause of blindness in older Americans, scientists at Washington University School of Medicine in St. Louis have found age is key in determining whether damaging blood vessels will form beneath the retina and contribute to vision loss. view more (2007-11-02)
Test for visual acuity could aid detection, rehabilitation of AMD
A computer-based method for evaluating the eye's ability to distinguish object details and shape in patients with age-related macular degeneration (AMD) could provide a more accurate way to assess the effectiveness of eye surgery or vision rehabilitation interventions with devices and training, according to a Canadian study. view more (2007-10-30)
'Twinkle after-effect' can help retinal patients detect vision loss quickly and cheaply
Scientists at Schepens Eye Research Institute, an affiliate of Harvard Medical School, have discovered a simple and inexpensive way for patients with retinal and other eye disease to keep track of changes in their vision loss. view more (2007-10-29)
'Twinkle' eye test could improve AMD diagnosis
Scientists at UCL (University College London) have developed a more reliable test for detecting vision loss in people with age-related macular disease (AMD), the leading cause of blindness in the UK and US. The method, which centres on a visual illusion, could lead to earlier self-diagnosis of sight deterioration - encouraging patients to access... view more... (2007-10-25)
