In future, the Three Blind Mice might be able to avoid running into the farmer’s wife. In a study, scientists managed to restore vision in mice born with congenital blindness, using gene therapy to reprogram base retinal cells into functioning rod photoreceptors.

A team at Japan's RIKEN Center for Developmental Biology (CDB) has used a genetic matching technique to overcome the problems of rejection and the use of immunosuppressant drugs when transplanting retinal pigment cells derived from the stem cells of one monkey into the eyes of other monkeys.

Retinitis pigmentosa, age-related macular degeneration, and diabetic retinopathy are all conditions that send people blind. Researchers claim to have developed a new optogenic therapy to restore the sight of mice suffering such diseases.

ScienceContrary to prior assumptions about the vision system, scientists have shown that the pattern of neural activity for a given scene changes fundamentally when the brightness of the environment increases or decreases – even within the same luminance range.
-
A promising new study suggests that a wireless, light-sensitive, and flexible nanotube-semiconductor nanocrystal film could potentially form part of a prosthetic device to replace damaged or defective retinas.

Apple today pushed out a refresh of its MacBook Pro with Retina display lineup, giving both the 13- and 15-inch models a bit more horsepower under the hood. Additionally, Apple has dropped the price of the top-of-the-line 15 inch model, perhaps making the high-end upgrade a little easier to justify.

ScienceResearchers at Johns Hopkins have constructed a functioning segment of a human retina out of stem cells that is able to respond to light.
-
Scientists at the Dresden-based Fraunhofer Institute for Photonic Microsystems (IPMS) have shrunk down retinal scanning technology in the hopes of making retinal scans a more widespread identification technology.
