The American Academy of Ophthalmology announced plans to launch a new scientific journal focused exclusively on retina-related eye diseases and conditions.
Visual blurring—like that produced by bifocals or multifocal lenses—may cause errors in foot position when walking. And that could contribute to the risk of tripping and falling in older adults, suggests a study in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.
A recent study shows that infants and toddlers take longer to notice new visual stimuli and are less accurate in their gaze than adults, but slowly improve as they age. The findings reinforce the importance of raising young children in stimulating environments, and set an important baseline as detection of developmental disorders increasingly rely on tracking eye movements. The paper, “Development and learning of saccadic eye movements in 7-42 month-old children” was published in the Journal of Vision.
Eye cancer took the life of author and neurologist Oliver Sacks last year, bringing attention to the rare, hard-to-treat disease. Now, a team led by scientists at Huntsman Cancer Institute at the University of Utah report in Cancer Cell that a mutation that causes the cancer relies on a protein, ARF6, to distribute cancer-promoting signals. Further, treatment with a drug made against the protein inhibits eye tumors formation.
Researchers from Brazil and Stanford University report on an ocular case study of three Brazilian infants with microcephaly presumed to be caused by Zika virus. Findings will appear in Ophthalmology, journal of the American Academy of Ophthalmology.
The number of people with visual impairment or blindness in the United States is expected to double to more than 8 million by 2050, according to projections based on the most recent census data and from studies funded by the National Eye Institute, part of the National Institutes of Health. Another 16.4 million Americans are expected to have difficulty seeing due to correctable refractive errors that can be fixed with glasses, contacts or surgery.
A study published today by researchers at the University of Southern California (USC) Roski Eye Institute in JAMA Ophthalmology found that the U.S. prevalence in visual impairment (VI) and blindness is expected to double over the next 35 years. By 2050, the number of Americans with a variety of eye disease and impairment issues, including age-related macular degeneration (AMD), glaucoma, diabetic retinopathy (DR) and cataracts, will dramatically increase impacting both individuals and society.
Researchers from the Schepens Eye Research Institute of Massachusetts Eye and Ear and Harvard Medical School have designed three new eyeglasses using high-power prisms to optimally expand the visual fields of patients with hemianopia, a condition in which the visual fields of both eyes are cut by half. The new designs, described in Optometry and Vision Science, address some limitations of existing prism correction available to this population.
Cornea tissue is a promising biomaterial for Brad Boyce, a Sandia National Laboratories materials scientist. More than a decade after Boyce and his co-workers investigated the biomechanics of dissected cow corneas, their findings have been confirmed in healthy human eyes.
Light sensitivity, or photophobia, is a frequent symptom of migraine headaches, which affect nearly 15 percent of the world’s population. A new study, led by researchers at Beth Israel Deaconess Medical Center (BIDMC) and published today in Brain, has found that exposing migraine sufferers to a narrow band of green light significantly reduces photophobia and can reduce headache severity.
Ever search desperately for something, then realize you're looking straight at it the whole time? Research indicates that vision is controlled by the part of the brain associated with thinking. And in sight, too, it can be absent minded.
Early structural changes in the back of the eye — now visible with a newly developed eye scan — may indicate the onset of Alzheimer’s disease. The research is being presented at the 2016 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Seattle, Wash.
A medicated silicone ring that rests on the surface of the eye and slowly releases medication reduced eye pressure in glaucoma patients by about 20 percent over six months. These multi-center randomized clinical trial results are the first published research on this type of continuous glaucoma drug delivery technology, which could benefit the nearly 3 million people in the United States with glaucoma. Published in Ophthalmology, journal of the American Academy of Ophthalmology.
