Scientists have found that an existing drug, already used in humans to treat alcohol use disorder, could help restore vision lost to conditions like age-related macular degeneration and retinitis pigmentosa. The discovery also uncovers a new mechanism … Continue reading Alcoholism treatment restores vision in mice with macular degeneration→

LED contact lens treatment may prevent diabetes-related blindness

Posted on by

If diabetes progresses too far, it can result in a potentially blinding condition known as retinopathy. And while existing treatments are invasive and often painful, there may be new hope in the form of an LED-equipped contact lens.Continue ReadingCate… Continue reading LED contact lens treatment may prevent diabetes-related blindness→

Body-sucking sleeping bag may help protect astronauts’ vision

Posted on by

When astronauts stay in outer space for extended periods, they frequently develop a vision problem known as spaceflight-associated neuro-ocular syndrome (SANS). Scientists are now trying to keep that from happening, via an experimental vacuum-sealed sl… Continue reading Body-sucking sleeping bag may help protect astronauts’ vision→

“Sight”-restoring bionic eye proceeds along the path to human trials

Posted on by

There may be new hope for people with certain types of blindness, as an experimental sight-restoring device has been deemed safe for implantation. It still has to be tested on humans, though, and it will likely provide a fairly rudimentary form of visi… Continue reading “Sight”-restoring bionic eye proceeds along the path to human trials→
