retina

Office workers may never have to worry again about viewing hilarious but NSFW images surreptitiously. A pair of glasses developed by Brother Industries can project images or documents directly onto a wearer's retinas.

The Retinal Imaging Display technology displays a small image 10 centimeters wide that appears to float about 1 meter (3.3 ft) in front of a user's eye. Images have an 800x600 resolution and refresh at 60Hz.

Blindness is the most debilitating of sensory impairments, and also the most vexing to cure. Now, MIT scientists have created a new kind of retinal implant that might help reverse the effects of two common forms of blindness. Drawing on the same principles as the cochlear implants that help the deaf, this implant wouldn't restore vision, but could help the blind navigate through everyday situations.

The retina is a lush layered field of tissue lining the back of the eye, a complex mix of specialized cells that serve as a transfer station where light signals are absorbed and sent to the brain to be translated into sight.

Researchers from University of Wisconsin, Madison have now created these unique retina cells from lowly skin cells -- opening the possibility that patients with damaged or diseased retinas might some day be able to grow themselves a cure from their own skin.

Researchers at the University of Florida claim to be the first to use targeted gene manipulation to take adult stem cells and change them into another kind of cell completely. They changed the stem cells, from bone marrow in this instance, into retinal cells. These retinal cells, when injected into blind mice, helped cure their blindness.
