Collagenase is a new invention to prevent blindness

NEW YORK (Reuters Health) – New research by scientists at the University of Newcastle in the UK has revealed a potential revolutionary way to treat eye damage and prevent blindness. The main method uses an enzyme that prevents stem cells, which can switch to new tissues, from losing their therapeutic abilities in the eyes after an infection. The results are also promising for people with blindness caused by corneal scarring caused by a wound or disease, the scientists said.

Stem cells treat eye damage, such as acid burns, wounds, or infections, by dividing and moving directly to the wound. This revolutionary development offers hope to some 500,000 people around the world who lose their sight each year due to chemical burns. Researchers at Newcastle University and the University of Missouri have been able to repair the effects of chemical burns on patients using live corneal tissue from an eye in the laboratory.

The researchers found that stem cells could lose their therapeutic properties when the tissue contained in the "hardening" after infection, but that the use of "collagenase", an enzyme intended to soften tissues, could reduce the hardening of the region, which made him more able to heal.

"It is an exciting development in the field of corneal biology that allows us to better understand how the vision works, but most importantly, it provides us with a new set of strategies for treating ophthalmic diseases", said Professor Chi Connon of Newcastle University. Until now not curable. "
