The small chip will help blind people see

Those who live in the dark can see again one day not far from the appearance of magic electronic eye technology.

According to the British Daily Mail, US scientists have taken a big step in visual recovery for visually impaired people with electronic eye systems. This device ignores signals to the eye and sends it directly to the human brain. This is a news that cannot be happier for millions of people around the world, making them somewhat warm and waiting for the day to see the light.

For the first time on Earth, doctors have successfully implanted a visual stimulus chip into the head of a woman in her 30s. This patient has completely lost sight in the past 7 years, and must live a life hard.

This device ignores signals to the eye and sends it directly to the human brain.

Eyesight gradually left this woman 8 years ago due to a rare disease called Vogt-Koyanagi-Harada syndrome that specialized in attacking pigments in the eyes. A year later, she was completely blind. Dr. Pouratian conducted insertion of stimulants - a small electrode array - into the back of her brain last August. During a four-hour cycle, the surgeon cut a small hole in the back of the skull and placed the stimulus on the surface of the brain.

Patients constantly see the exact signals scientists send to the visual cortex - the part of the brain that normally receives images from the optic nerves.

"The moment she sees color for the first time is an emotional experience. It touches the hearts of all of us. And based on these results, the system has the ability to restore her eyesight. " Dr. Pouratian said.

This technology will look at human eyes as an excess, meaning it can restore vision to people who have lost an eye or become blind due to malignant cancer.

Doctors at the University of California Los Angeles (USA) are waiting for permission from the authorities to connect the system to a camera and a pair of glasses called Orion I helps send moving images directly to Brain by using the camera of the glasses.

Orion I is a successful continuation of Argus II, the device first introduced at Manchester Royal Eye Hospital last year, which uses a similar camera to send images to a back implant device. of the eye.

But the difference is that Argus II works on a patient who still has some retinal cells that work. The new Orion I system took a step further by sending signals directly to the brain. Currently, in the UK, there are more than two million people who are blind or blind, with no hope of curing.

Electronic eye operation.

Describe the electronic eye operating procedure in the above image:

1. A tiny video camera placed in a frame captures moving images and sends them through a cable connected to a computer.

2. The computer - carried by the user in a bag - transfers the received images into electronic signals and sends them back to a glass antenna.

3. The signals are then wirelessly transmitted to a transplanted device in the back of the skull.

4. They are sent to electrodes placed on the surface of the brain.

5. Electrodes that stimulate nerve cells in the visual cortex allow the wearer to see.

Professor Paulo Stanga, an eye doctor at the University of Manchester, said: "A large number of patients will benefit from this technology, such as those who have lost an eye on the battlefield or the serious injury ".

Meanwhile, Royal Pescod Dan Pescod said: "This is a very interesting and life-changing thing, although the research is still in its infancy".

Dr. Robert Greenberg, President of Second Sight, Orion I development company, added: "It's rare that new technology development can provide such capabilities. By ignoring the nerves. Visual and direct cortical stimulation, Orion I has the ability to restore vision to blind patients for any reason such as glaucoma, cancer, retinopathy, or injury ".

In the future, visually impaired people will have the opportunity to wear a pair of glasses, helping them not only see things around but also become more fashionable.

They have the right to hope, right from this moment.
