Glaucoma is one of the leading causes of vision loss and blindness worldwide. In glaucoma patients, the optic nerve, which relays information from the eye to the brain, is damaged, though the molecular cause of nerve damage is unclear. Dr. Simon John, from Tufts University in Boston, and colleagues specifically wanted to understand the earliest events that lead to optic nerve damage in glaucoma. Using a mouse model of the disease, the researchers showed that inflammatory immune cells called...

For the first time, scientists at the University of Wisconsin-Madison have made early retina structures containing proliferating neuroretinal progenitor cells using induced pluripotent stem (iPS) cells derived from human blood. And in another advance, the retina structures showed the capacity to form layers of cells — as the retina does in normal human development — and these cells possessed the machinery that could allow them to communicate information. (Light-sensitive...

A new paradigm to explain glaucoma is rapidly emerging, and it is generating brain-based treatment advances that may ultimately vanquish the disease known as the "sneak thief of sight." A review now available in Ophthalmology, the journal of the American Academy of Ophthalmology, reports that some top researchers no longer think of glaucoma solely as an eye disease. Instead, they view it as a neurologic disorder that causes nerve cells in the brain to degenerate and die, similar to what...

A new study identifies specific cell-stress signaling pathways that link injury of the optic nerve with irreversible vision loss. The research, published by Cell Press in the February 9 issue of the journal Neuron, may lead to new strategies that will help to protect vulnerable neurons in the retina after optic nerve damage and diseases. Retinal ganglion cells (RGCs) send visual information from the retina to the brain through long processes called axons. The axons of the RGCs are bundled...

Glaucoma is a major cause of vision loss in the United States, affecting about 2.2 million Americans. The National Eye Institute (NEI) leads research toward better prevention, detection, and treatment of this often silent but devastating disease. During Glaucoma Awareness Month, NEI highlights research advances, showcases education and awareness efforts, and reminds Americans that early detection and treatment is the best way to prevent vision loss. NEI advises all Americans at risk of...

PINE BROOK, N.J., Nov. 2, 2011 /PRNewswire/ -- Diopsys, Inc. announced today that its Visual Evoked Potential (VEP) Vision Testing Systems have been awarded the CE mark. The company has begun a roll-out of its patented vision testing devices to EU customers. Diopsys completed a rigorous inspection of its total quality system in order to qualify for CE status. "Having the CE mark opens many opportunities for us to provide clinicians and patients across the EU access to our advanced VEP...

Study suggests glaucoma screenings are happening too late Glaucoma is the second leading cause of blindness worldwide. Although it can be treated, new research shows Canadians may not be doing enough to protect themselves. According to a new study by Lawson Health Research Institute's Dr. Cindy Hutnik, many Canadian glaucoma patients are not screened until the disease has reached moderate or advanced stages. Glaucoma is known as the "silent thief of sight." It slowly and irreversibly...

People who are deaf benefit from better vision due to the fact their retinas develop differently, experts at the University of Sheffield have shown. The research, which was funded by RNID "“ Action on Hearing Loss and published June 1, 2011 in the journal PLoS ONE suggests that the retina of adults who are either born deaf or have an onset of deafness within the very first years of life actually develops differently to hearing adults in order for it to be able to capture more peripheral...

May explain why blind migraine sufferers get attacks that are triggered by light The anatomy of migraine "“ a close look at the neurobiology of the disease "“ focuses on the thalamus, the area of the brain that is involved in sensory perception and regulation of motor functions, in one a major session of the 53rd Annual Scientific Meeting of the American Headache Society meeting here this week. The session examines the role of the thalamus in regulating pain transmission in...
