Researchers have for the first time identified stem cells in the region of the optic nerve, which transmits signals from the eye to the brain. The finding presents a new theory on why the most common form of glaucoma may develop and provides potential new ways for treatment.
Glaucoma is a leading cause of blindness globally. It causes damage to eye nerves due to a buildup of fluid that does not drain properly.
“This is the first time that neural progenitor cells have been discovered in the optic nerve. Without these cells, the nerve is unable to repair itself from damage caused by glaucoma or other conditions. This may lead to permanent vision loss and disability,” said one of the lead authors. They also noted that it took 52 trials to successfully grow the cells in a culture. This discovery may open new avenues for the treatment of eye diseases that affect the optic nerve but a lot more research is needed.
