Artificial retina is the device which helps in bringing back the light to a blind eye. This device returns back the light to those who are suffering from retinal diseases. This retina aims to restore the reading ability, recognition of the face and age related macular degeneration.
Things Required For Artificial Retina:
Some of the things which are required for artificial retina are:
- Patient wears glasses with a small video camera in it.
- This camera sends the video wirelessly to the pack containing microprocessor which is placed on the belt.
- This microprocessor processes the video signal.
- The processed signal is sent to the antenna in the eye
- This antenna is connected to the electrodes which are implanted in the old retina.
- Electrodes transmits the signal to the optic nerves which in turn sends the image to the vision center of the brain.
Working Of Artificial Retina:
In this procedure a small camera is mounted on the glass of the eye which captures the image and sends the information to a microprocessor placed on the belt.
This microprocessor converts the received data to an electronic signal and transmits it back to the receiver placed on the eye. The receiver in turn sends the signal to the micro electrode array through a thin, tiny cable which stimulates it to emit the pulses.
This device bypasses photoreceptor cells and transmits the electric signals directly to the visible cells of the retina. These pulses travel through the optic nerves and ultimately reach the brain where they are perceived as the patterns of light and dark shades depending upon the electrode stimulation. Patients slowly learns to interpret these visual patterns.
