bionic vision becomes a reality

Retinal tissue is an extension of the brain tissue and can be accessed via the ganglion cells. It’s also a great place to plug in a bionic vision system.

Scientist have known for 20 years that stimulating the retinal surface at the ganglion
cell layer, the entry to the optic nerve, caused patients to see light flashes.

The microelectronics package to place permanently in the eye and a signal back to retinal ganglion cells have been created by Pixium Vision.

The Bionic VRS system converts light into signals that the neurons in the brain will understand.

The technology is in the review process in Great Britain, and here with the FDA. But early results are promising.

According to Moorsfields Eye Hospital, “A patient with the blinding condition retinitis pigmentosa has reported that he could differentiate between light and dark for the first time in five years following the successful implant and activation of the IRIS II® bionic vision system.

The patient is the first in the UK to receive the IRIS II® bionic vision system, which uses a bio-inspired camera to stimulate a retinal implant and send image signals to the brain. The innovative system allows patients who have lost their sight to regain partial visual perception and lead more independent lives.”
