The therapy, called photobiomodulation or “red light” therapy, can reduce the risk of vision loss and slow progression of the &ldquo...
Japanese researchers have successfully used a transplant of human stem cells to close a hole in a key part of a monkey's retina.
They say the achievement could pave the way for better treatment of small gaps that form in the macula, the central part of the eye's retina.
These macular holes can cause distorted or blurred vision, making it hard to see fine details, read or drive a ca...
Scientists say they've discovered a protein that seems crucial to the onset of age-related macular degeneration (AMD), a common cause of blindness in older people.
The research is in its very early stages, but it might help lead to the first effective therapy agains...
Research in rats and hibernating squirrels has pinpointed a naturally occurring protein that appears to reverse cataracts, scientists report.

Gene therapy may restore vision to children and adults robbed of their sight by a rare inherited condition called Leber congenital amaurosis, researchers report.
The illness is caused by mutations in the GUCY2D gene, which is critical to producing proteins that enable vision. People with this form of Leber congenital amaurosis (LCA1) typically lose their vision in early childhood. Just un...
You've noticed your young child complains of headaches and rubs their eyes a lot. Does that mean it's time to get glasses?

“There is a period -- approximately the first eight years of...
When it comes to Medicaid and vision care, how much coverage people get depends on the state in which they live, a new study finds.
Most Medicaid enrollees have at least some routine vision coverage, but an estimated 6.5 million adults live in states without comprehensive coverage for routine eye exams, researchers found. Likewise, about 14.6 million adults didn’t have comprehensiv...
In her youth, Shola, an English Shepherd Dog, was a member of the Edale Mountain Rescue Team, a corps of U.K. pooches charged with helping hurt and stranded hikers.
But Shola was retired as part of the Rescue Team after a rare genetic disease affecting dogs, called progressive retinal atrophy (PRA), robbed her of her sight.
It's too late for Shola, but new research has led to a ge...

An injectable gene therapy caused measurable improvements in vision among a small group of people with inherited blindness, an early-stage clinical trial says.
Researchers recruited 14 people with Leber Congenital Amaurosis (LCA), a rare genetic condition that causes babies to lose some or all of their sight from birth.
Eleven of the 14 had measurable improvements in the vision of o...
Most folks think of blinking as the eyes' version of windshield wipers, clearing the eye of debris and maybe lubricating it, too.
But blinking is much more than that, researchers report: It also helps the brain process what it's seeing.
That's perhaps counterintuitive: Wouldn't it make sense to not blink, so eyes are receiving an uninterrupted stream of information?
Today is your last chance until 2044 to see a total eclipse of the sun in the continental United States.
