Genetic causes behind rare eye disorder discovered
Posted On: Sept. 10, 2011
Washington, Sept 9 (ANI): Researchers from the University of Leeds and the Flinders University in Adelaide, Australia, have discovered the genetic causes behind a rare form of inherited eye disorders that lead to cataracts and glaucoma in young children, using next-generation DNA sequencing techniques. The findings should simplify identifying affected families at risk of conceiving children with severely impaired vision, ...

Researchers find new role of protein that causes deaf-blindness in humans
Posted On: Aug. 19, 2011
London, August 19 (ANI): A new role for a protein that is mutated in Usher syndrome - one of the most common forms of deaf-blindness in humans - has been discovered by University of Iowa scientists. The study indicated that the protein called harmonin, which is known to be involved in sound sensing in the inner ear, may also play ...

Critical role for night blindness gene identified
Posted On: Aug. 16, 2011
Washington, August 10 (ANI): A scientist has determined how a particular gene makes night vision possible. The study focuses on a gene called nyctalopin. Mutations in the gene result in inherited "night blindness," a loss of vision in low-light environments. "Until now, our understanding of the role of this gene in the visual signaling pathway has been very limited," said ...

New device enables 'seeing' with ears instead of eyes
Posted On: Aug. 8, 2011
Washington, Aug 7 (ANI): The American Psychological Association has demonstrated a device that enables "seeing" with one's ears rather than eyes, at the organization's 119th Annual Convention this week. The device known as the vOICe, which helps determine where and what an object is without using eyesight, was selected as best demonstration, with a prize of 3,000 dollars. "Imagine losing ...

Soon, smart specs to help the blind 'see'!
Posted On: July 16, 2011
London, July 14 : Oxford University researchers, who have been inspired by the technology in Xbox Kinect games consoles and iPads, are developing 'smart spectacles' which promises to change the lives of thousands of blind people by allowing them to 'see'. The spectacles use tiny cameras and a pocket computer to alert wearers to objects and people ahead, reports the ...

Holding smartphones too near while reading messages can hamper your vision
Posted On: July 16, 2011
Washington, July 13 (ANI): A new study has suggested that smart phone users reading text messages and internet pages hold their devices at a closer distance than they would for printed text-which may have important implications for prescribing vision correction. According to the study by Mark Rosenfield and colleagues of SUNY State College of Optometry, New York, optometrists should pay ...

Soon, test to detect risk of blindness before any signs develop
Posted On: June 10, 2011
Melbourne, June 9 (ANI): Researchers at the Queensland University of Technology are working on a test that they hope will help detect people at risk of developing age-related macular degeneration (AMD) - the country's leading cause of blindness. AMD is a progressive disease that could be significantly minimized with lifestyle changes, so early detection is crucial, explained eye specialist Beatrix ...

Early cellular cause of dry eye disease identified
Posted On: June 2, 2011
Washington, June 1 (ANI): Researchers at the Harvard Medical School in Boston have identified the early cellular cause of dry eye disease. They are the first to discover the natural killer (NK) cells, a type of cell that provides innate immunity to the eyes, as promoting the inflammation that plays a critical role in the development of dry eye disease. ...

Spatial awareness 'not triggered by vision alone'
Posted On: June 1, 2011
Washington, May 27 (ANI): A new study has suggested that the brain's understanding of spatial awareness is not triggered by vision alone but involves other senses such as touch. Researchers at the University of Edinburgh took MRI brain scans of both sighted volunteers and others who had been blind since birth while they examined three-dimensional spaces. Both groups were first ...

How retinas develop
Posted On: May 23, 2011
Washington, May 22 (ANI): Studies by UC Santa Barbara researchers on expanding vision have revealed the basic biological understanding on how retinas develop. "These studies individually demonstrate the genetic determinants of nerve cell number. Together, they show that different nerve cell types are modulated independent of one another," said Benjamin E. Reese, senior author and professor with the Neuroscience Research ...

Scientists re-grow retinas, restore vision using skin's stem cells
Posted On: May 20, 2011
Washington, May 17 (ANI): For the first time, scientists from Boston's Schepens Eye Research Institute have used stem cells derived from skin to re-grow areas of the retina and improve vision. The results of their study hold great promise for future treatments and cures for diseases such as age-related macular degeneration, retinitis pigmentosa, diabetic retinopathy and other retinal diseases that ...

Now, a new eye jab that could cure blindness!
Posted On: April 18, 2011
London, April 17 (ANI): Scientists have developed a new eye injection, which they claim could cure blindness. The treatment, which costs 2,000 pounds, could stop the onset of blindness and can also help restore loss of vision. The steroid implant, which releases an anti-inflammatory drug near the retina, is used to prevent the sudden loss of sight caused by a ...

Novel cell therapy slows down vision loss in eye disease
Posted On: April 11, 2011
Washington, April 08 (ANI): Results of a clinical trail have highlighted the benefit of the use of a neurotrophic factor to treat a severe form of age-related macular degeneration called geographic atrophy (GA). The finding could offer hope to millions suffering from GA. A phase 2 clinical trials for the treatment of GA has become the first study to show ...

Thyroid hormone is crucial in controlling eye's visual pigments
Posted On: April 4, 2011
Washington, Mar 30 (ANI): Thyroid hormone plays a very important role where the eyes are concerned, as it controls which visual pigment is produced in the cones. Previously, it was assumed that the colour sensitivity of the cones is fixed in the adult retina. But researchers at the Max Planck Institute for Brain Research in Frankfurt/M., together with colleagues at ...

How omega-3 fatty acids keep blindness at bay
Posted On: Feb. 10, 2011
Washington, Feb 10 (ANI): Previous research has shown that omega-3 fatty acids - commonly found in fish oil - can prevent retinopathy, a major form of blindness that affects people with diabetes and premature babies, in a mouse model of the disease. Now a follow-up study, from the same research team at Children's Hospital Boston, has revealed how exactly omega-3 ...
