A research, which was published in the journal “The Lancet”, has revealed that a group of US researchers has successfully treated vision loss problem in two US patients by using human embryonic stem cells. It was a one-off treatment in which human embryo stem cells were used for treatment of vision loss.

The trial was a part of the study in which the researchers wanted to assure that the treatment is safe. This is the reason that they roped in two women who were legally declared blind, and had no chance of getting their vision back ever.

One of the patients was in her 50s while the second one was in 70s. Both the women, after receiving the treatment, said that have got benefit from the treatment and that too within four months.

The woman in her 70s was suffering from muscle degeneration which further leads to the loss of eye sight. Another middle-aged woman was suffering from different vision problem, but the common connection between the two was that both were blind.

After receiving the treatment, in which both women were injected with 50, 000 retinal cells that were grown in a laboratory from the embryonic stem cells, the patients claimed to have benefited with the treatment.

Now, both the women could read alphabets which was earlier not possible for them and can now see single-finger movements. The study authors said, “Macular degeneration is an interesting condition to look at because we don't need to create many cells (to inject), and the eye is an advantageous site because we can image it well and follow the fate of the graft”.

However, it is still due to judge whether the effect they received was from the dummy capsule or from injections or other medicines which were given so that the body accepts the cells easily.
