Hope for eye treatment using stem cells

Help

The first results of a trial involving human embryonic stem cells have been published in a medical journal.

The Lancet reports how two women in the USA with eye disease were injected with stem cells and both apparently showed some slight improvement in vision.

The company Advanced Cell Technology (ACT) says the patients are doing well four months on from the trial.

Trials of the same technique have now started at London's Moorfields Eye Hospital.

Fergus Walsh reports.
