Femtosecond laser systems may improve outcomes for cataract surgery over conventional approaches, according to investigators who reported on large series of patients at the American Academy of Ophthalmology (AAO) and Asia-Pacific Academy of Ophthalmology 2012 Joint Meeting. Femtosecond lasers have been on the market for about a year. The LenSx (Alcon, Inc) system was approved in 2011 and the Cat

Posted by Praveen (#2) 4177 days ago (Editorial)
Using a new technique called cryo-electron tomography, two research teams at Baylor College of Medicine have created a three-dimensional map that gives a better understanding of how the architecture of the rod sensory cilium (part of one type of photoreceptor in the eye) is changed by genetic mutation and how that affects its ability to transport proteins as part of the light-sensing process.To s
Engineering a Photo-Switch for Nerve Cells in the Eye and Brain
Posted by Praveen (#2) 4177 days ago (Editorial)
Chemists and vision scientists at the University of Illinois at Chicago have designed a light-sensitive molecule that can stimulate a neural response in cells of the retina and brain -- a possible first step to overcoming degenerative eye diseases like age-related macular degeneration, or to quieting epileptic seizures.To see more details visit,
Smoking and Cataracts
Posted by Praveen (#2) 4184 days ago (Editorial)
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. Reported in Investigative Ophthalmology & Visual Science (Smoking and Risk of Age-related Cataract: A Meta-analysis), the new findings are the result of a meta-analys
OPHTHALMOLOGY: New Look At Putting the Lid On Those Dry Eyes
Posted by Praveen (#2) 4184 days ago (Editorial)
ONE of the most common symptoms of vision-related health problem is dry eyes, it can be a function of age, but it is becoming more frequent in people of all ages, who spend too many hours staring at a computer screen, say eye specialists. Australian scientists have developed a simple test of eyelid sensitivity to help vision specialists to evaluate the extent of dry eyes, and give appropriate tre
Novel Drug May Stop Eye Disease
Posted by Praveen (#2) 4184 days ago (Editorial)
A new drug developed by researchers from Flinders University, in partnership with collaborators in Melbourne, could hold the key to better treatment of some blinding eye diseases. Members of the research team, led by Professor Keryn Williams of Flinders Centre for Ophthalmology, Eye and Vision Research, believe they can stop or even reverse the progression of disease by blocking a particular prot
Child Poisonings from Eye Drops, Nose Sprays
Posted by Praveen (#2) 4184 days ago (Editorial)
Over-the-counter eye drops and nose sprays contain powerful drugs that are poisonous in surprisingly small amounts if swallowed, the FDA warns. Unwary parents often leave these products within easy reach of curious children. From 1997 through 2009, eye drops injured more than 4,500 children under the age of 5 and nasal sprays injured more than 1,100, according to the U.S. Consumer Product Safety
Aggregation of Proteins in Cells May Result In Diseases
Posted by Praveen (#2) 4184 days ago (Editorial)
Changes in the structure of proteins can lead to various diseases, such as Alzheimer's, type 2 diabetes and corneal dystrophy. A research team from Aarhus University has now discovered how a particular protein can damage cells. These results may lead to the development of drugs to treat corneal dystrophy in the future. Corneal dystrophy is caused by a mutation of a protein called TGFBIp in the c
