Vision changes can entail major problems in everyday life. To a high degree, vision affects our ability to keep our balance, and balance affects our ability to move around. “People with long-term dizziness sometimes rely a lot on their vision and do not use the very quick and effective balance system provided by sensory information […]Continue Reading ...
It was surprisingly simple. University of California, Berkeley, scientists inserted a gene for a green-light receptor into the eyes of blind mice and, a month later, they were navigating around obstacles as easily as mice with no vision problems. They were able to see motion, brightness changes over a thousandfold range and fine detail on […]Continue Reading ...
Autosomal dominant optic atrophy and cataract is an eye disorder that is characterized by impaired vision. Most affected individuals have decreased sharpness of vision (visual acuity) from birth, while others begin to experience vision problems in early childhood or later. In affected individuals, both eyes are usually affected equally. However, the severity of the vision […]Continue Reading ...
What is vision screening? A vision screening, also called an eye test, is a brief exam that looks for potential vision problems and eye disorders. Vision screenings are often done by primary care providers as part of a child’s regular checkup. Sometimes screenings are given to children by school nurses. Vision screening is not used […]Continue Reading ...
New research suggests that smoking more than 20 cigarettes a day may damage a person’s vision and disrupt their ability to see colors. st.noon | Shutterstock In a study comparing smokers and non-smokers, Dr. Steven Silverstein and colleagues from Rutgers University found that smokers could not differentiate between colors as well as non-smokers could and […]Continue Reading ...
Smoking more than 20 cigarettes a day can damage your vision, a study co-authored by a Rutgers researcher finds. The research appears in the journal Psychiatry Research. The Centers for Disease Control and Prevention estimates that 34.3 million adults in the United States currently smoke cigarettes and that more than 16 million live with a […]Continue Reading ...
Researchers from Queen’s University Belfast, in collaboration with the University of Bristol, are leading a cutting-edge project, named the “MONARCH” study, that could benefit eye disease patients whilst saving both time and money within the NHS. The MONARCH study aims to investigate if patients with an eye condition called wet age-related macular degeneration (AMD) could […]Continue Reading ...
Glaucoma results in progressive damage to the optic nerve, the part of the eye that carries visual information from the eye to the brain. Credit: National Eye Institute The most common tests for glaucoma can underestimate the severity of the condition by not detecting the presence of central vision loss, according to a new Columbia […]Continue Reading ...
Millions of Americans are progressively losing their sight as cells in their eyes deteriorate, but a new therapy developed by researchers at the University of California, Berkeley, could help prolong useful vision and delay total blindness. The treatment — involving either a drug or gene therapy — works by reducing the noise generated by nerve […]Continue Reading ...
Mar 5 2019 As Age-Related Macular Degeneration/Low Vision Awareness Month comes to a close, we’re sharing three stories by Bonnielin Swenor, Ph.D., M.P.H., assistant professor of ophthalmology at the Wilmer Eye Institute in the Johns Hopkins University School of Medicine, and an assistant professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health. […]Continue Reading ...
When it comes to understanding how neurons connect to form circuits in the brain, scientists for decades have turned to the retina of the humble laboratory mouse as an ideal model organism. But as a model for vision and vision-related diseases, mice simply aren’t equipped. The problem, said Joshua Sanes, the Jeff C. Tarr Professor […]Continue Reading ...
A woman treated at Oxford Eye Hospital has become the first person in the world to undergo a gene therapy operation that could combat the most common cause of vision loss in the Western World. Motortion Films | Shutterstock The treatment is the first to target the underlying genetic cause of age-related macular degeneration (AMD), […]Continue Reading ...
by E.j. Mundell, Healthday Reporter (HealthDay)—New research on 12 high school football players tracked for a season found that repeat head impacts affected the boys’ vision—even if those hits didn’t result in concussion. The Indiana University researchers stressed that the changes in vision did seem temporary. But since vision tests are part of certain testing […]Continue Reading ...
A new treatment for patients with a form of congenital retinal blindness has shown success in improving vision, according to results published today in Nature Medicine led by researchers at the Scheie Eye Institute in the Perelman School of Medicine at the University of Pennsylvania. The treatment was designed for patients with CEP290 mutations and […]Continue Reading ...
Going blind affects all senses, and disrupts memory ability If mice lose their vision immediately after birth due to a genetic defect, this has a considerable impact, both on the organization of the cerebral cortex and on memory ability. This is the conclusion drawn by researchers at Ruhr-Universität Bochum in a study published online in […]Continue Reading ...
