Second Sight Provides Treatment for Blindness

Second Sight Provides Treatment for Blindness


Retinitis Pigmentosa (RP)

Retinal Pigmentosa is an inherited, degenerative eye disease that causes severe visual impairment due to the progressive degeneration of the rod photoreceptor cells in the retina[1] Wikipedia ko]. In common language it is an eye disease which effects any age group from child to adult. 

Argus® II Retinal Prosthesis System

As a cure of this disease Second Sight presents Argus® II Retinal Prosthesis System[2]. Argus II is also known as bionic eye which is intended to provide electrical simulation of the retina to induce visual perception in blind individuals.

How does Argus work?

Inside the human eye an antenna is set which receives the signals processed and transmitted wirelessly by Argus II Retinal Prosthesis System. This system consists of a miniature camera housed in the patient's glasses which captures a scene. Video is than sent to a small computer which is also worn by the patient known as VPU(Video Processing Unit). VPU processes and transforms the image into instruction which are sent back to the glasses via a cable.
The treatment will start in 2017 in two hospitals Manchester Royal Eye Hospital and Moorfields Eye Hospital. The patients will then have to do the follow up for a year which will decide it the implant was a success.[3]
