National Glaucoma Research (NGR), a program of the BrightFocus Foundation, a 501(c)3 non-profit, funds research to find a cure and educates the public about glaucoma. www.brightfocus.org/glaucoma Glaucoma is  a group of eye diseases that leads to damage of the optic nerve (the bundle of nerve fibers that carries information from the eye to the brain), which can then lead to vision loss and possibly blindness. Optic nerve damage usually occurs in the presence of high eye (intraocular) pressure; however, it can occur with normal or even less than normal eye pressure. Globally, 60.5 million had glaucoma in 2010. Given the aging of the world's population, this number may increase to almost 80 million by 2020.
