Your eye could someday house its own high-tech information center, tracking important changes and letting you know when it’s time to see an eye doctor.

University of Washington engineers have designed a low-power sensor that could be placed permanently in a person’s eye to track hard-to-measure changes in eye pressure. The sensor would be embedded with an artificial lens during cataract surgery and would detect pressure changes instantaneously, then transmit the data wirelessly using radio frequency waves. (more…)

One-two punch could be key in treating blindness

Researchers have discovered that using two kinds of therapy in tandem may be a knockout combo against inherited disorders that cause blindness. While their study focused on man’s best friend, the treatment could help restore vision in people, too.

Published in the journal Molecular Therapy, the study builds on earlier work by Michigan State University veterinary ophthalmologist András Komáromy and colleagues. In 2010, they restored day vision in dogs suffering from achromatopsia, an inherited form of total color blindness, by replacing the mutant gene associated with the condition. (more…)

Photoreceptor Transplant Restores Vision in Mice

Scientists from the UCL Institute of Ophthalmology have shown for the first time that transplanting light-sensitive photoreceptors into the eyes of visually impaired mice can restore their vision.

The research, published in Nature, suggests that transplanting photoreceptors – light-sensitive nerve cells that line the back of the eye – could form the basis of a new treatment to restore sight in people with degenerative eye diseases. (more…)
