| EYE TEST PEERS INTO HEAT-RELATED MULTIPLE SCLEROSIS SYMPTOMS |
| A bodysuit that heats or cools a patient, combined with painless measurements of eye movements, is providing multiple sclerosis researchers at UT Southwestern Medical Center with a new tool to study the mysterious link between body temperature and severity of MS symptoms. |

| TIGHT NECKTIES BOOST GLAUCOMA RISK |
| Wearing a tight necktie can increase the chances of developing glaucoma, a group of serious eye diseases, researchers have found. |

| WHEN PATTING THE DOG CAN SEND YOU BLIND |
| People can become infected from a worm that causes blindness simply by stroking a dog that carries the parasite, according to new research. |

| FIRST LOOK AT 'BIONIC EYE' |
| An Australian-invented 'bionic eye' device is about to begin human trials.
The device consists of a silicon chip inserted into the eye, which is designed to act like a retina — receiving images captured by a pair of glasses worn by the user. |

| LIGHT COULD REPAIR EYE INJURIES |
| HOW do you treat people blinded by light? With more light. Shining near-infrared radiation on damaged retinal cells can keep them alive and prevent permanent blindness.
The US Defense Advance Research Projects Agency is funding research into the method and hopes to use it to treat people whose eyes are damaged by lasers. A number of US military personnel, including a helicopter pilot over Bosnia in 1998, have suffered laser eye injuries. |

| AUSSIE CORNEA HELPS FIGHT WORLD BLINDNESS |
| An artificial cornea developed in Australia is now ready for production and commercial release throughout the world, according to an announcement this week.
The AlphaCor was developed by researchers at the Lions Eye Institute of Western Australia and Argus Biomedical Pty Ltd. The announcement was made as one of a series of medical achievements for Australian Medical Research Week. |
|
| COULD THE WESTERN DIET CAUSE SHORT-SIGHTEDNESS? |
| The modern western diet may be causing more myopia in children, according to an Australian researcher.
Dr Jennie Brand-Miller, a nutrition scientist at the University of Sydney working in a team led by Dr Loren Cordain, an evolutionary biologist at Colorado State University suggests that more processed food in the diet is increasing insulin production and distorting the normal growth of the eyeball. |
|
| IS THIS THE CELL THAT COULD REVOLUTIONISE MEDICINE? |
| IT MIGHT turn out to be the most important cell ever discovered. It's a stem cell found in adults that can turn into every single tissue in the body.
Until now, only stem cells from early embryos were thought to be able to do this. If the finding is confirmed, it will mean cells from your own body could one day be turned into all sorts of perfectly matched replacement tissues and even organs. |
|
| GENE THERAPY MAY BE A TOOL TO PREVENT BLINDNESS |
| Reduces blinding blood vessel growth by up to 90 percent in laboratory mice. Gene therapy may one day be used to halt or even prevent the overgrowth of blood vessels in the eye that blinds patients with macular degeneration and diabetic retinopathy, according to two recent studies led by researchers at Johns Hopkins' Wilmer Eye Institute. |
|
| EYE TISSUE TO BE GROWN TO ORDER |
| The first Australian trials of a new transplant technique for victims of eye injuries or burns are expected to take place in Queensland later this year. The trials at Royal Brisbane Hospital will involve transplanting specialised “skin grafts for the eye”, artificially grown in the laboratory from the patient’s own tissue. |
|
| COLOR VISION OUT OF THE CORNER OF THE EYE |
| Scientists from Sydney, Gottingen, and New York have now elucidated how color is perceived in the peripheral visual field. In most humans, color vision is best in central vision and is far less sensitive in the periphery. |
