Pocket-sized retina camera, no dilating required

It’s the part of the eye exam everyone hates: the pupil-dilating eye drops. The drops work by opening the pupil and preventing the iris from constricting in response to light and are often used for routine examination and photography of the back of the eye. The drops sting, can take up to 30 minutes to… Read More


Myopia cell discovered in retina: Dysfunction of cell may be linked to amount of time a child spends indoors

Northwestern Medicine scientists have discovered a cell in the retina that may cause myopia when it dysfunctions. The dysfunction may be linked to the amount of time a child spends indoors and away from natural light. “This discovery could lead to a new therapeutic target to control myopia,” said Greg Schwartz, lead investigator and assistant… Read More


Fish oil component helps damaged brain, retina cells survive, shows research

A team of researchers led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health New Orleans School of Medicine, has shown for the first time that NDP1, a signaling molecule made from DHA, can trigger the production of a protective protein against toxic free radicals and… Read More


Research on retinal pigment epithelial cells promises new future treatment for glaucoma patients

Scientific research builds its own momentum as one discovery triggers another, building an ongoing wave of unexpected possibilities. In the world of glaucoma, such a surge began when advances in stem cell research opened doors experts had never imagined. With this new perspective, they began to consider innovative ways to use specialized cells in the… Read More


A closer look at the eye: New retinal imaging technique

Researchers at the University of Rochester Medical Center have developed a new imaging technique that could revolutionize how eye health and disease are assessed. The group is first to be able to make out individual cells at the back of the eye that are implicated in vision loss in diseases like glaucoma. They hope their… Read More


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
