Stanford scientists introduce new retinal prosthesis treatment

14 May 2012

A new form of eye surgery being trialled at the Stanford University School of Medicine could have the means to better restore sight to blind people.

Scientists from the institute have detailed an innovative form of retinal prosthesis which sees miniscule solar-panel-like cells fitted underneath the retina of an eye.

Electric currents then pass through the photodiodes on the chip, which aims to trigger signals in the retina. These signals then flow to a person's brain and allow a person to regain their vision.

Daniel Palanker, the associate professor of ophthalmology and one of the paper's senior authors, acknowledged: "It works like the solar panels on your roof, converting light into electric current. But instead of the current flowing to your refrigerator, it flows into your retina."

In other developments where eye treatment is concerned, a recent study entitled IVAN has stated that Lucentis and its cheaper alternative Avastin are both effective for battling wet age-related macular degeneration.
