Leber's Congenital Amauros, a rare form of blindness that has not had any cure, is a disease that affects 3,000 people a year and 130,000 worldwide.  Recently there has been new hope for restoring site in patients suffering from the disease.  Researchers found that if they could begin gene therapy treatment before signal pathways begin to be unused in the brain, sight can be  markedly improved.  Gene therapy in voles injecting healthy replacement genes that can take over for defective ones in a patients genome.  The study is a landmark for vision loss.  One patient was able to read an eye chart while another one was able to run an obstacle course.  The hope is that with further research, patients suffering from other forms of eye disorders such as macular degeneration and pigmentosa will also have hope.
