Gold injections restore vision

In a new study published in the journal ACS Nano, the team found that injecting gold nanoparticles into the eyes of mice with retinal disorders helped stimulate the rodents' visual systems and bring back some vision.

When targeted with infrared lasers, the microscopic gold pieces reproduce electrical signals similar to those emitted by cells in the retina that are essential to eyesight but are damaged by conditions like macular degeneration, which affects some 20 million Americans.

"This is a new type of retinal prosthesis that has the potential to restore vision lost to retinal degeneration without requiring any kind of complicated surgery or genetic modification," lead author Jiarui Nie, a researcher at Brown University and the National Institutes of Health, said in a statement about the work. "We believe this technique could potentially transform treatment paradigms for retinal degenerative conditions."
