Adult stem cell: blind can now see

Dozens of people who were blinded or otherwise suffered severe eye damage when they were splashed with caustic chemicals had their sight restored with transplants of their own stem cells — a stunning success for the burgeoning cell-therapy field, Italian researchers reported Wednesday.

The treatment worked completely in 82 of 107 eyes and partially in 14 others, with benefits lasting up to a decade so far. One man whose eyes were severely damaged more than 60 years ago now has near-normal vision.

“This is a roaring success,” said ophthalmologist Dr. Ivan Schwab of the University of California, Davis, who

Stem Cells Restore Sight in India

Ashok Chakravarti remembers the moment he went blind.
It was on February 18, 2002. He was at work, at a chemical plant, when a pipe carrying sodium hydroxide (caustic soda) started to leak.
“I was fixing the leak when the chemical splashed into my eyes,” he says. The accident damaged the outermost layer of his eyes, the cornea.

Chakravarti is among thousands of Indians who lose their sight in chemical accidents each year.
Today, some of those people can see again, thanks to scientists at the L.V. Prasad Eye Institute, in Hyderabad.

The institute is treating patients with stem cells – not the controversial

GREAT BRITAIN – Embryonic stem cells cure blindness in an hour

After much hope and controversy, for the first time stem cells have proven to have the ability to cure blindness.

The news comes from a study on age-related macular degeneration (AMD) of the retina, the most common cause of blindness in individuals over the age of 50.

The Sunday Times reports that the treatment was developed by a group of British researchers, who say that in the next six to seven years the treatment will become a routine operation, which will not last more than an hour.

The treatment involves the replacement of a layer of degenerated cells with new cells created

Stem cell therapy works in blind patients in first trial

Scientists have improved the sight of two people who were almost blind by injecting their eyes with stem cells from embryos.

The two women, both registered as blind, saw their vision improve in a matter of weeks after being given the embryo-derived cells in the US safety trial.

The breakthrough holds out the hope of a cure in the future for age-related macular degeneration, which currently affects some 500,000 people in Britain.
The results, published this week in The Lancet, provide a major boost for the field of stem cell reseach.

Professor Daniel Brison, of the North West Embryonic

India – Stem cells from single cornea of dead now treating many

Patients suffering from blindness now need not wait for donors as doctors have found a way to treat many with the stem cells derived from the cornea of a dead body.
Doctors at the AIIMS and a private clinic in the national capital are using corneal surface stem cells from a cadaver’s (dead person) eye for curing corneal injuries in many.

“We have used the corneal surface stem cells of cadaver’s eye for patients with corneal injury and have been able to correct many vision,” Dr Radhika Tandon, Associate Professor, Department of Opthalmology, AIIMS said, adding “this has been
