HOW OUR RETINA WORKS?

BLINDNESS MEANS LOSS OF VISION. A COMPLETELY BLIND INDIVISUAL
UNABLE TO SEE ANYTHING EVEN WITH THE USE OF EYE GLASSES , CONTACT LENSES , MEDICINE OR SURGERY.
8O% OF BLINDNESS OCCURS IN PEOPLE OVER 50 YEARS OLD.
COMMON CAUSES :- MACULAR DEGENERATION , TRAUMATIC INJURIES , GLAUCOMA etc.
LESS COMMON CAUSES :- VIT-A DEFICIENCY , RETINITIS PIGMENTOSA , RETINOPATHY OF PREMATURITY etc.

THE BIONIC SYSTEM
1: Camera on glasses views image2: Signals are sent to hand-held device3: Processed information is sent back to glasses and wirelessly transmitted to receiver under surface of eye4: Receiver sends information to electrodes in retinal implant5: Electrodes stimulate retina to send information to brain

ADVANTAGES
Compact Size – 6x6 mm
Diagnostic Capability
Reduction of stress upon retina
D ISADVANTAGES
Costly
If a single part of the chip is damaged the total technique will be meaningless.

C O N C L U S I O N
Researchers throughout the wor ld have looked for ways to improve people 's l i ves wi th art ifi c ia l , b ion ic dev ices .
Bionic dev ices are be ing deve loped to do more than rep lace defect ive parts .
Researchers are a lso us ing them to fi ght i l lnesses .
Prov id ing power to run b ionic implants and making connect ions to the bra in 's contro l system pose the two great cha l lenges for b iomedica l engineer ing.
Sc ient ist are now look ing at dev ices l ike b ion ic arms, tongues, noses etc .
