If corrective surgery is performed within 8 days after symptoms begin, patients with macula-off rhegmatogenous retinal detachment (RRD) can experience slow improvements in postoperative visual acuity during a period lasting as long as a year, according to a study published online November 17 in the British Journal of Ophthalmology. "Our findings suggest that the longer the macula is detached the

Posted by Praveen (#2) 4171 days ago (Editorial)
For the very first time researchers have streamed braille patterns directly into a blind patient's retina, allowing him to read four-letter words accurately and quickly with an ocular neuroprosthetic device. The device, the Argus II, has been implanted in over 50 patients, many of who can now see color, movement and objects. It uses a small camera mounted on a pair of glasses, a portable processo
Lab Close To Growing Full Corneas
Posted by Praveen (#2) 4171 days ago (Editorial)
Auckland University researchers believe they are just five to 10 years from growing entire human corneas in the laboratory to implant into patients' damaged eyes. Professor Charles McGhee, the head of the university's National Eye Centre, performed New Zealand's first laboratory-cultured stem cell operations on patients with damaged corneas in 2010, improving the sight of most of the affected eye
Eye Health Indicator details revealed

Details of how the first-ever public health indicator for preventable sight loss will be measured were released this week and have been welcomed by the eye sector. The indicator will be introduced as part of the public health outcomes framework in England next April and will monitor the major causes of preventable sight loss in adults. Public Health England, the organization responsible for the
Total Iron, Calcium Intake Linked to Glaucoma Risk

High intake of total calcium and iron appear to be associated with greater odds of self-reported glaucoma, researchers from the University of California, San Francisco, determined from an analysis of the National Health and Nutrition Examination Survey (NHANES).The findings were reported here at the American Academy of Ophthalmology (AAO) 2012 Annual Meeting by Sophia Y. Wang, a medical student a

New Breakthrough Can Help Save Vision
Posted by Praveen (#2) 4175 days ago (Editorial)
Certain cells, called corneal limbal stromal cells, have been identified in the eye, which could lead to a new treatment to cure blinding eye conditions. The finding was published in the British Journal for Ophthalmology and came from a team led by Professor Andrew Lotery, at the University of Southampton, who discovered that these cells, which were taken from the front surface of the eye, could
Compound found in rosemary protects against macular degeneration in laboratory model

Researchers discover that carnosic acid, a component of the herb rosemary, promotes eyehealth in rodents—providing a possible new approach for treating conditions such as age-related macular degeneration. Left: Control cells exposed to hydrogen peroxide. Right: Cells treated with carnosic acid are protected from hydrogen peroxide. Live cells are stained green, dead cells are stained red. Herbs wi
