INTRODUCTION:

INTRODUCTION Form of neural prosthesis to restore vision An external camera and a retinal implanted chip makes it possible It is often usable for those who suffers from age-related macular degeneration (AMD) or retinal pigmentosa

WHO IS ELIGIBLE ?:

WHO IS ELIGIBLE ? Those who had a severe Retinal Pigmentosa Those who are suffering from age-related macular degeneration

DEVICE:

DEVICE Digital camera Video-processing microchip Radio transmitter Radio receiver Retinal implant

WORKING:

WORKING Camera on glasses views image Signals are sent to video processing microchip Processed information is sent back to receiver Receiver sends information to electrodes in retinal implant Electrodes stimulate retina to send information to brain

NORMAL & ARTIFICIAL VISIONS:

NORMAL & ARTIFICIAL VISIONS Normal vision - Begins when light enters and strike on photoreceptor cells. These cells convert light to electric impulses that are sent to brain via optic nerves. Artificial vision - The camera captures images and sends to retina implant. It stimulates neurons. The stimulated neurons send information to brain via optic nerves.

DISADVANTAGES:

DISADVANTAGES Surgery is required to implant the electrode array Costly The vision is restored partially Repairing is difficult if any of the devices got damaged Those who lost their visions due to other reasons could not use this device

CONCLUSION:

CONCLUSION Revolutionary piece of technology Good news for AMD and retinal pigmentosa patients
