Glaucoma is a term used to describe a group of conditions that can cause damage to the optic nerve of the eye. The optic nerve is a tightly-formed collection of nerve fibers that carry visual information from the retina to the brain. In order to enjoy good vision, it’s important to have a healthy optic nerve. But with glaucoma, pressure builds up within the eye causing optic nerve damage. The result can be impaired vision, even blindness. And once vision loss occurs it cannot be reversed. In fact, glaucoma is the second most common cause of blindness in the United States. Because early-stage glaucoma has no noticeable symptoms, timely detection through regular eye exams is imperative, and can save many people from serious vision loss. (3003)
