How Cutting-Edge Technology Restores Vision in Blind People
Posted Nov 28 2012 12:18am
Yesterday I was reading a
magazine about a lady who loved colors. She usually dressed in bright outfits
and painted her home with all the hues of the rainbow. She reminded people of
the sixties and seventies. Colors play an important role in life. But some
people are not very lucky in this regard. They are affected by an uncommon disease
called Retinitis Pigmentosa which gradually robs them off their sight.
Retinitis Pigmentosa is a
hereditary disease which damages the retina and leads to blindness. The retina
is a tissue at the back of the inner eye which converts light images to nerve
signals and sends them to the brain. But scientists are hard at work round the
clock to bring about a change in these people’s lives, as you are about to read
in this post.
In the past, researchers have
developed retinal implants that have allowed the blind people to see shapes and
objects within days of the implant being installed. And now the scientists have
gone a mile further and streamed Braille patterns in to the patient’s retina.
By God’s grace this person could read four letter words accurately and quickly
with a help of an ocular neuro prosthetic device.
Neuroprosthetic devices are
electrical or mechanical devices which substitute functions lost by disease or
injury. This scientific milestone could revolutionize and improve the quality
of life for about 200,000 people in the world who suffer from blindness as a
result of retinitis pigmentosa. To
understand the working process of this device I have attached a youtube video.
There are other therapies
which are novel and very interesting to read. Oh! I cannot wait to share it
with you. The people in white coat have shown that transplanting light
sensitive photo receptors into the eyes of the visually impaired mice can
Things are getting more
interesting even as I type this. Scientists have found cells called the corneal
limbal stromal cells which are taken from the front surface of the eye. Now
these cells have stem cell properties and can be cultured to create retinal
cells. This could result in the development of new techniques to treat
retinitis pigmentosa and macular degeneration, a disease which gradually
deteriorates macula which is at the center of retina.
It is a sincere request, that
you should remember all these researchers in your prayers, asking God to give
them wisdom and understanding to find answers for all the puzzling problems haunting
this planet. And this is my heartfelt wish that one day all the people born
under the sun would look at the heavens and enjoy the beautiful hues of the
