Can a person see even after death or can his eyes sense light even several hours after death? It sounds like a story from a movie, but scientists have made a surprising claim that has shocked the medical world. science Has created a stir in the world. A new research has revealed that a person’s eyes can respond to light even 10 hours after his death. Let us know how scientists did this miracle and how it will help in removing blindness.
How did life return to the eyes after death?
The retina at the back of our eye (retina) There is a layer of name. Its job is to capture light and convert it into electrical signals and send it to our brain, through which we are able to see. Usually, as soon as death occurs, the blood flow in the body stops, due to which the retina stops getting oxygen and it immediately stops working.
But the Center for Genomic Regulation (CRG)’s scientists came up with an amazing idea. He created a system in the lab that works exactly like the blood circulation of our body. Through this system, he delivered oxygen and essential nutrients to the retina of the donated eyes. The result was that even 10 hours after death the retina started responding to the brightness of light.
So can a person see after death?
This discovery does not at all mean that a person will start seeing again after death or that his eyesight will return. Scientists have made it clear that this retina was working with the help of a machine outside the body. Since this eye was not connected to the brain, no human being can see anything consciously. This is just a scientific process where the cells remained alive.
Will be of great help in removing blindness
Even if it does not provide light to a dead person, this discovery can prove to be a boon for millions of people who are suffering from serious eye diseases.
Retina will remain protected for 24 hours
Scientists found that with this technique the structure of the retina can be preserved for 24 hours. This will give doctors more time to do research on human retina in the laboratory.
Testing new medicines is easy
Till now, scientists used to test eye medicines on animals, but now they will be able to see the effect of new medicines and treatments directly on the human retina.
treatment of serious diseases
This causes blurred vision with increasing age (Macular Degeneration) and will help in finding solutions to incurable diseases like eye damage due to diabetes.
Is eye transplant possible?
Scientists believe that this discovery is a historic step towards vision restoration in the future. However, completely transplanting the eyes and connecting them to the nerves of the brain is still a huge challenge. Nevertheless, this research has awakened a new ray of hope for doctors around the world and millions of people who have lost their eyesight.
