Glaucoma refers to any condition that causes damage to the optic nerve, but its cause is generally unknown. Researchers in London are establishing a potential link between the development of glaucoma and the onset of Alzheimer’s disease.
In both cases, the same “plaque” proteins are involved in the conditions’ development. Researchers speculate that the same substances that destroy brain cells in Alzheimer’s patients also destroy the optic nerve cells of those with glaucoma. Source: http://www.lef.org/
