Brain diseases manifest in the retina of the eye

Diseases of the central nervous system (CNS) may manifest as pathological changes in the retina of the eye. Research from the University of Eastern Finland (UEF) shows that retinal changes may be detected earlier than brain changes. Findings from mouse models suggest that eye examination could be used as a noninvasive screening tool for human… Read More


Alzheimer’s disease proteins could be at fault for leading cause of vision loss among older people

Research from the University of Southampton gives new insight into possible causes of Age-related Macular Degeneration (AMD), a leading cause of vision loss among people aged 50 and older. The study, published in the journal Experimental Eye Research, discovered that a group of proteins, which are linked to Alzheimer’s disease, are able to accumulate in… Read More


Woman who lost vision to diabetes shares experience to raise awareness

It was Labor Day 2015 when Rosetta Ivey-Foster, a 76-year-old retired bank clerk, learned first-hand how quickly diabetes can deteriorate vision. Swift action restored most of her eyesight. Diagnosed with type 1 diabetes more than 25 years ago, Ivey-Foster had carefully managed her disease. That included getting regular comprehensive dilated eye exams to detect early… Read More


Zika and glaucoma linked for first time in new study

A team of researchers in Brazil and at the Yale School of Public Health has published the first report demonstrating that the Zika virus can cause glaucoma in infants who were exposed to the virus during gestation. Exposure to the Zika virus during pregnancy causes birth defects of the central nervous system, including microcephaly. Brazilian… Read More


Brain training video games help low-vision kids see better

A new study by vision scientists at the University of Rochester and Vanderbilt University found that children with poor vision see vast improvement in their peripheral vision after only eight hours of training via kid-friendly video games. Most surprising to the scientists was the range of visual gains the children made, and that the gains… Read More


The importance of being protected: How to choose your sunglasses

Experts from the University of Alicante (UA) have found that prolonged exposure to the sun increases the chance of developing alterations in the lens by 4%. Choosing the right pair of sunglasses can reduce such complications. Despite the fact that the vast majority of the harmful radiation from the sun is absorbed by the atmosphere,… Read More


New test needed to assess the quality, safety of sunglasses

Revision of standards is needed to test sunglasses quality and establish safe limits for the lenses’ UV filters, according to research published in the open access journal Biomedical Engineering OnLine. Exposure to the sun may deteriorate your sunglasses over time and the lenses may become lighter and so alter the category under which they are… Read More


Artificial retinas: Promising leads towards clearer vision

A major therapeutic challenge, the retinal prostheses that have been under development during the past ten years can enable some blind subjects to perceive light signals, but the image thus restored is still far from being clear. By comparing in rodents the activity of the visual cortex generated artificially by implants against that produced by… Read More


Surprise discovery in the blink of an eye

We probably do it every day, but scientists have only just discovered a distinct new way in which we move our eyes. The team from the University of Tübingen in Germany assessed the eye movements of 11 subjects using tiny wires attached to the cornea and with infrared video tracking. In results published in eLife,… Read More
