In a new study, Sinha and his colleagues have now discovered anatomical changes that occur in the brains of these patients after their sight is restored. These changes, seen in the structure and organization of the brain’s white matter, appear to underlie some of the visual improvements that the researchers also observed in these patients.
Uncorrected refractive error—or, simply needing eyeglasses—is the main cause of visual impairment in United States youth. A lack of glasses leads to decreased school and work performance and worse overall health and wellbeing. And now, research shows that a few key barriers stop young people from getting the glasses they need.

Blinking is crucial for the eye. It’s how animals clean their eyes, protect them, and even communicate. But how and why did blinking originate? Researchers at the Georgia Institute of Technology, Seton Hill University, and Pennsylvania State University studied the mudskipper, an amphibious fish that spends most of its day on land, to better understand why blinking is a fundamental behavior for life on land.

Buck Institute professor Pankaj Kapahi thinks the eye is a window to aging. His lab, in collaboration with Google Health and Zuckerberg San Francisco General Hospital, has shown how imaging of the fundus, the blood vessel-rich tissue in the retina, can be used to track human aging, in a way that is noninvasive, less expensive and more accurate than other aging clocks that are currently available.

New UCLA research in mice suggests that “dormant” cone photoreceptors in the degenerating retina are not dormant at all, but continue to function, producing responses to light and driving retinal activity for vision.
Metabolic pathways consist of a series of biochemical reactions in cells that convert a starting component into other products. There is growing evidence that metabolic pathways coupled with external stress factors influence the health of cells and tissues.
Corneal transplants can be the last step to returning clear vision to many patients suffering from eye disease. Each year, approximately 80,000 corneal transplantations take place in the U.S. Worldwide, more than 184,000 corneal transplantation surgeries are performed annually.
Today, Research to Prevent Blindness (RPB) and more than 30 other organizations are convening in Washington DC for the Vision Research Funding Partnership event, which was organized around the theme of “The Research Pipeline – From Premise to Patient.”
Research suggests that Medicare reimbursements for complex cataract surgery cover less than two minutes of operating time, and an increase to reimbursements for the procedure may be justified. Complex cataract surgery requires more time and resources than simple cataract surgery, and this study indicates that the incremental reimbursement for the complex surgery is not enough to offset the increased costs.

Staphylococcus aureus, Clostridioides difficile, Candida auris, Drug-resistant Shigella. These bacteria not only have difficult names to pronounce, but they are also difficult to fight off. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antimicrobial resistance is an urgent global public health threat.

What should you consider when choosing the best kind of artificial tears for your eyes?
Questions remain about artificial tears linked to an outbreak of Pseudomonas aeruginosa infections involving 64 people in 13 states, including 8 cases of vision loss, as well as lung and urinary tract infections, and one death. Federal agencies warned people to stop using EzriCare and Delsam Pharma artificial tears after tests of opened bottles used by those affected found a rare, extensively drug-resistant strain of P. aeruginosa. The strain had never been reported in the United States.What is clear is that eye health experts have advice for people using artificial tears, which are sold over the counter and widely used for eye irritation associated with dry eye disease, contact lens use, and refractive surgery, as well among those using other eye drops regularly, such as for glaucoma.
Why putting lip balm on eyelids is bad for your eyes
Face blindness, a mystifying condition that can trick us into believing we recognize people we’ve never met or make us fail to recognize those we have, has been previously estimated to affect between 2 and 2.5 percent of people in the world. Now, a new study by researchers at Harvard Medical School (HMS) and the VA Boston Healthcare System is providing fresh insights into the disorder, suggesting it may be more common than currently believed.
