ABSTRACT

The most sensitive and important part of a biological structure is “EYE”.This is the only amazing organ which helps the biological organisms to

visualise its thinking capability. The beautiful and colourful world around, is enjoyed by every creature, with the help of eyes.

Can we ever imagine life without eye sight???

But its true that about 700,000 people in the developed world are diagnosed with age-related macular degeneration (AMD)each year, and 1.5 million people worldwide suffer from a disease called retinitis pigmentosa(RP). In both of these diseases, retinal cells, which convert light into nerve impulses at the back of the eye, gradually die. As is commonly seen in with retinitis pigmentosa, these patients all have severe narrowing of their visual fields down to a very small central circle, and all patients suffering with it are legally blind.

But, the existing VLSI technology has brought an innovative revolution in the field of science. One of the brilliant inventions and discoveries to help the blind people, using VLSI

technology, is responsible for the evolution of “Artificial silicon retina” (ASR).

A silicon chip that faith fully mimics the neural circuitary of a real retina could lead to better bionic eyes for those

with vision loss. The paper presented will give a clear idea about implantation of silicon retina into eye, and how it functions so that the diseased can regain their vision.

The main objective to use silicon retina in biological field is to make the blind to visualise the things. This artificial silicon retina is a boon to man kind. But the disadvantage of this is it works only when the light focuses on it(day time). The probability of working of silicon retina in the absense of light is yet to be discovered by the scientists.

The paper depicts the pictorial view of the diodes, retinal implantation of
