‘Positive stress’ helps protect eye from glaucoma
Working in mice, scientists at Washington University
School of Medicine in St. Louis have devised a treatment that prevents
the optic nerve injury that occurs in glaucoma, a neurodegenerative
disease that is a leading cause of blindness. Researchers increased the resistance of optic nerve cells to damage
by repeatedly exposing the mice to low levels of oxygen similar to those
found at high altitudes.
