Prevalent in Most Common Form

1 Glaucoma Tied to Mutations on Two Chromosomes

New research that involved analyzing the DNA of over 6,000 people has found that glaucoma are likely linked to variations on two genes, one on chromosome 8 and one on chromosome 9. It was observed the 50 percent had what is known as primary open-angle glaucoma which is commonly associated with abnormally high eye pressure but one-third of those with this common form had normal eye pressures. Glaucoma, which affects about 2.2 million Americans according to the U.S. National Eye Institute and is a common form of blindness around the world, leads to irreversible damage to the optic nerve. Researchers hope this knowledge will lead to the development of treatments that prevent the disease. The complete study can be found online in the April 26 issue of PLoS Genetics.
