Glaucoma is a disease that causes damage to the optic nerve resulting in loss of vision. The optic nerve is a bundle nerve fibers that are a critical part of transmitting the visual signals from the eye to the brain. The most common form of glaucoma is associated with an increase pressure inside the eye. This increase in pressure can lead to progressive damage to the optic nerve.  Not everyone with high eye pressure will develop glaucoma, and many people with normal eye pressure will develop glaucoma. The treatment of glaucoma is aimed at reducing intraocular pressure. The most common first line treatment of glaucoma is usually prescription eye drops that must be taken regularly.  To establish a diagnosis of glaucoma, several risk factors must be present, and these are assessed at your yearly comprehensive eye exam.
