The new centre will combine functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG) to study brain processes involved in everyday mental tasks. Research at the centre may lead to improved treatments for conditions like strokes, multiple sclerosis, and schizophrenia.
Four new studies expose disparities in children's eye care based on race, income, and insurance status. Minorities and uninsured children are significantly less likely to receive eye exams or corrective lenses than their peers.
Research suggests that children who spend more time studying and reading are more likely to develop myopia. However, the study found no link between screen time and the development of myopia. The study of 366 eighth-grade children highlights the importance of hereditary factors in the development of myopia.
Using adaptive optics, researchers can now clearly see features such as blood flow in the retina, enabling early diagnosis of diseases. This technology will help eye doctors track changes in patients with conditions like diabetes and glaucoma.
Researchers have developed a new technology using adaptive optics to improve diagnosis of eye diseases. The technology enables doctors to see individual cells in the retina, allowing for early detection and treatment of conditions such as glaucoma and age-related macular degeneration.
The study reveals a sophisticated neural computation in the retina that enables directional motion detection. The circuit, involving three redundant mechanisms, is crucial for tracking moving objects and providing dynamic visual information to the brain.
A recent study found that near-eye displays, like eyeglasses with a built-in monitor, can increase ease of use and performance comparable to traditional computer screens. However, some users experienced eyestrain more with these devices.
The Journal of Rehabilitation Research & Development features articles on life satisfaction following spinal cord and traumatic brain injury, as well as a study on foot models for ulcer-prevention treatment. A preliminary study on genetically engineered spinal cord implants also highlights potential improvements in bladder structure af...
A study found that people with type 2 diabetes experienced increased oscillatory potentials after dark adaptation, which decreased with oxygen inhalation. The researchers suggest that diabetic patients might benefit from a modified night-time illumination cycle during sleep to reduce oxygen consumption in the retina.
Brown University researchers will develop a research-based register of controlled trials related to ophthalmology and optometry. They aim to provide evidence-based treatments to patients, helping physicians and consumers make informed healthcare choices.
A recent study by Ohio State University found that almost one in 13 soft contact lens wearers develop severe corneal abrasions, leading to infections or other problems. The study suggests that optometrists monitor their patients for such abrasions and proper hygiene habits can prevent them.
A University of California at Berkeley study found that up to 30% of U.S. children who use computers may need special eyewear to reduce the risk of premature vision problems. The research also shows a strong correlation between computer use and premature myopia, or nearsightedness.
A new study from Ohio State University found that nearly a quarter of LASIK patients experience nighttime vision problems, including halos, starbursts, and glare. These symptoms may persist long after the eye heals and are linked to factors such as having had the surgery repeated or having flatter corneas at the outset.
A study of 50 patients found that almost twice as many preferred disposable extended-wear lenses due to their convenience. The subjects reported no differences in vision, comfort, or eye health between the two types of lenses.
Researchers found that wearing reverse-geometry gas permeable contact lenses for 7 nights improved the daytime eyesight of 7 out of 8 nearsighted subjects. By the end of a 60-day trial, all subjects could see clearly without contacts or glasses.
A new study published in Nature found no association between nighttime lighting and the development of nearsightedness in children. The study surveyed over 1,200 children and found that parents' eye sight and genetics played a more significant role in causing myopia.
