Among the primary causes of adult-onset blindness are degenerative diseases of the retina, such as macular degeneration and retinitis pigmentosa. While some treatments have been developed that slow down the rate of degeneration, the clinical situation is still generally unsatisfactory. But if you could grow a new retina, transplant might be a possible cure. Now new hope is springing up from a research project at the University of Wisconsin-Madison in which scientists have succeeded in growing human retinal tissue from stem cells.
