British Study: Stem Cell Transplants Restore 2 Patients' Vision

The surgery includes inserting the patch under the retina in each eye.

Douglas, who is from London, developed severe age-related macular degeneration in his right eye three years ago. The macular is the part of the eye that allows you to see straight ahead - whether to recognise faces, watch TV or read a book.

He says: "In the months prior to the activity my sight was extremely poor and I couldn't see anything out of my correct eye".

"It's brilliant what the team have done and I feel so lucky to have been given my sight back".

It involves wiping out a patient's immune system using cancer drugs and then rebooting it with a stem cell transplant.

At the point when this help layer comes up short, it causes macular degeneration and blindness.

Doctors have devised a way of building a new retinal pigment epithelium and surgically implanting it into the eye.

Results from a very small clinical trial of a stem cell-based therapy for macular degeneration was published Monday in Nature Biotechnology.

Other teams are testing so-called induced pluripotent stem cells ― adult human cells that have been reprogrammed to a youthful, versatile state. The task takes up to two hours.

Sensex climbs 139 points to close above 33000-mark
Continuous foreign funds inflow and positive speculations too influenced the market sentiments, according to brokers. In the 30-share Sensex pack, Bharti Airtel rose the most at 4.39 per cent, followed by NTPC at 2.11 per cent.

Council to mine Facebook data of Games' visitors
Meanwhile, Facebook said that it is "outraged" by the misuse of data by Cambridge Analytica , according to local media reports . She told Channel 4 News, "I'm not accepting their response so therefore I'll be applying to the court for a warrant".

Avengers: Infinity War Will Be Marvel's Longest Movie Yet
Russo explained that Infinity War's two-part structure made it easier to balance the enormous cast . Though going by the number of superheroes in the movie, it surely makes sense.

However, da Cruz stopped short of calling this a cure because it does not completely restore normal vision, BBC News reported.

Two patients, a man in his eighties and a woman in her sixties, are now able to read again after the procedure, which is the first of its kind.

However, since the operation he has now been able to use the eye to read a newspaper, to the speed of between 60 and 80 words a minute.

Eight more patients will take part in this clinical trial. Once that happens, the next step would be to ensure patients who need the transplant actually get it. There is a concern that the transplanted cells could become cancerous, although researchers haven't seen any signs of this so far, the BBC reported.

Professor Coffey said: "This study represents real progress in regenerative medicine and opens the door on new treatment options for people with age-related macular degeneration".

Prof Richard Burt, lead investigator, Northwestern University Chicago, told me: "The data is stunningly in favour of transplant against the best available drugs - the neurological community has been sceptical about this treatment, but these results will change that".

Doctors in the United Kingdom say they have taken an important step towards treating a common form of blindness - wet age-related macular degeneration (AMD).

While the peripheral vision isn't affected, meaning patients don't have total sight loss, it can make it very hard to live independently and can lead to a legal classification of blindness. Doctors said they hoped the treatment could be an effective method of countering both variations of age-related blindness. The dry condition, which accounts for 70 percent to 90 percent of all cases, can develop into the wet type, which is marked by abnormal blood vessels leaking fluid or blood into the region of the macula in the center of the retina.
