Scientists regrow human corneas to restore vision
In one of the first known examples of making tissue from an adult-derived human stem cell, scientists have found a way to enhance regrowth of corneal tissue to restore vision.
Limbal stem cells, identified with new marker, could reverse a leading cause of blindness
Boston researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule known as ABCB5 that acts as a marker for hard-to-find limbal stem cells.

Allergan, Inc., has announced that the U.S. Food and Drug Administration (FDA) has approved OZURDEX® as a new treatment option for diabetic macular edema (DME) in adult patients who have an…
Research may help prevent eye injuries among soldiers
Researchers at UTSA are discovering that the current protective eyewear used by our U.S. armed forces might not be adequate to protect soldiers exposed to explosive blasts.
New resource to help more blind young people into work backed by UK Ministers
The Royal London Society for Blind People, a leading charity for blind and partially sighted young people has launched a dual purpose resource pack.
Wearable computer gloves ‘help teach braille’
Researchers from Georgia Tech have created a wearable computer glove that they say can teach people to read and write braille, even when their attention is elsewhere.
Higher education levels linked to increased nearsightedness
Those of us on our computers may want to take a break and head outside; new research suggests the more time spent studying and the less time outside, the higher the risk of myopia.
Progress made in understanding how the brain processes visual information

“Goodnight room, goodnight moon. Goodnight cow jumping over the moon…”A children’s classic that already is a candidate for the all-time best feel-good book, “Goodnight Moon,” has gotten a…
Quantitative trait locus analysis enables researchers to explore how the nervous system develops
The circuitry of the central nervous system is immensely complex and, as a result, sometimes confounding.
Some aspects of sight are not impaired by mental overload
From animated ads on Main Street to downtown intersections packed with pedestrians, the eyes of urban drivers have much to see.
Molecular ‘yin-yang’ of blood vessel growth may point the way to new anti-cancer strategies
Biologists at The Scripps Research Institute (TSRI) have discovered a crucial process that regulates the development of blood vessels.
‘Smart glasses’ for the near-blind start trials in public spaces
Scientists in the UK are testing smart glasses that can help people with limited vision navigate their environment in public spaces, such as shopping malls.
Night vision adversely affected by alcohol
Ethanol in the tear-film is one of the causes: it covers the surface of the eye, disturbs the outer layer and favours evaporation of the aqueous content of the tear, deteriorating the optical quality…
Some neurons turn to neighbors to get rid of old mitochondria
It’s broadly assumed that cells degrade and recycle their own old or damaged organelles, but researchers at University of California, San Diego School of Medicine, The Johns Hopkins University School…
