Scientists on Sunday said they had identified six genetic variants linked to glaucoma, a discovery that should help earlier diagnosis and better treatment for this often-debilitating eye disease. The flaws came to light in a minute trawl through the genome of tens of thousands of people in more than half a dozen countries, comparing the DNA of those with glaucoma against those who were otherwise healthy. Glaucoma -- the leading cause of irreversible eye disease in the world -- is caused by damage to the optical nerve, usually by a buildup of fluid pressure in the eyeball. Further work on exactly how faulty genes cause glaucoma could also lead to better treatments, the scientists said.
