Stem cell treatment restores man’s sight in right eye after 25 years

At 18 years old, there are several life-changing moments that young people look forward to. For some, it involves graduating from high school, starting college, and being able to cast a vote in an election. For others, this momentous occasion symbolizes the official start of adulthood.

For James O’ Brien, this milestone was marked by a rather unfortunate event where ammonia was thrown at his face in a random attack. As a result of this incident, the surface of his right eye was burned and he was left completely blind in his right eye.

Fast forward 25 years and thanks to an experimental stem cell treatment, James is able to see out of his right eye for the first time since the attack.
