New cells found that could help save people’s sight

New cells found that could help save people’s sight

ScienceDaily (Nov. 8, 2012) — Eye experts and scientists at the University of Southampton have discovered specific cells in the eye which could lead to a new procedure to treat and cure blinding eye conditions. Led by Professor Andrew Lotery, the study found that cells called corneal limbal stromal cells, taken from the front surface of the eye have stem cell properties and could be cultured to create retinal cells Continue reading

Smoking may lead to cataracts in aging population

ScienceDaily (Oct. 12, 2012) — Cigarette smoking is a well-known risk factor for a wide-range of diseases. Now, scientists have evidence that smoking may also increase the risk of age-related cataract, the leading cause of blindness and vision loss in the world Continue reading

Stem cells improve visual function in blind mice

Stem cells improve visual function in blind mice

ScienceDaily (Oct. 1, 2012) — An experimental treatment for blindness, developed from a patient’s skin cells, improved the vision of blind mice in a study conducted by Columbia ophthalmologists and stem cell researchers Continue reading

Gene that causes a form of deafness discovered

ScienceDaily (Sep. 30, 2012) — Researchers at the University of Cincinnati and Cincinnati Children’s Hospital Medical Center have found a new genetic mutation responsible for deafness and hearing loss associated with Usher syndrome type 1. Continue reading

First implantation of prototype bionic eye with 24 electrodes: ‘All of a sudden I could see a little flash of light’

First implantation of prototype bionic eye with 24 electrodes: ‘All of a sudden I could see a little flash of light’

ScienceDaily (Aug. 31, 2012) — In a major development, Bionic Vision Australia researchers have successfully performed the first implantation of an early prototype bionic eye with 24 electrodes. Ms Dianne Ashworth has profound vision loss due to retinitis pigmentosa, an inherited condition. Continue reading

Breakthrough treatment reduces post-surgical scarring for glaucoma patients

Breakthrough treatment reduces post-surgical scarring for glaucoma patients

ScienceDaily (July 27, 2012) — Scientists at the Singapore Eye Research Institute (SERI) and Nanyang Technological University (NTU) have developed an innovative way to combat post-surgical scarring for glaucoma patients. A clinical trial has shown that the use of a new drug delivery method has resulted in 40 per cent fewer injections needed by glaucoma patients to prevent scarring after surgery Continue reading

Novel therapy may prevent damage to the retina in diabetic eye diseases

Novel therapy may prevent damage to the retina in diabetic eye diseases

ScienceDaily (July 27, 2012) — Researchers at the University of Michigan Kellogg Eye Center have identified a compound that could interrupt the chain of events that cause damage to the retina in diabetic retinopathy. Continue reading

Microneedles target therapeutics to back of the eye

Microneedles target therapeutics to back of the eye

ScienceDaily (July 22, 2012) — Thanks to tiny microneedles, eye doctors may soon have a better way to treat diseases such as macular degeneration that affect tissues in the back of the eye. That could be important as the population ages and develops more eye-related illnesses — and as pharmaceutical companies develop new drugs that otherwise could only be administered by injecting into the eye with a hypodermic needle. For the first time, researchers from the Georgia Institute of Technology and Emory University have demonstrated that microneedles less than a millimeter in length can deliver drug molecules and particles to the eye in an animal model Continue reading

Nanoscale scaffolds and stem cells show promise in cartilage repair

Nanoscale scaffolds and stem cells show promise in cartilage repair

ScienceDaily (July 17, 2012) — Johns Hopkins tissue engineers have used tiny, artificial fiber scaffolds thousands of times smaller than a human hair to help coax stem cells into developing into cartilage, the shock-absorbing lining of elbows and knees that often wears thin from injury or age. Reporting online June 4 in the Proceedings of the National Academy of Sciences , investigators produce an important component of cartilage in both laboratory and animal models Continue reading
