Presently stem cell transplantation is getting huge popularity for restoring sight. Scientists from the University of Louisville claimed that they have find that by successfully generating new cells in retina, stem cells can restore damage retinal tissue.

The findings are an important step toward helping people who experience vision loss and blindness as a result of age-related macular degeneration and hereditary retinal degeneration.

In the study researchers discovered that stem cells removed from bone marrow were attracted to damaged retinal pigment epithelium, the pigmented cell layer just outside the retina.

The University reported that the successful result of the study is definitely a ray of hope for people who are blind or already faced blindness due to macular degeneration  and hereditary retinal degeneration

According to researcher Suzanne Ildstad, more research is required to optimize the outcome and potential repair of damaged retinal pigment epithelium.

Researchers believe that this same technique that could cure optical defects, would be useful to treat congestive heart failure, diabetes, osteoporosis, Alzheimer, Parkinson diseases and spinal cord injuries.
