Glaucoma is an eye disease that damages the optic nerve. This damage can lead to vision loss or blindness. The optic nerve carries visual information from the eye to the brain and is essential for good vision. Damage to the optic nerve is often related to high intraocular pressure. However, glaucoma can occur even with normal intraocular pressure. Glaucoma can occur at any age, but it is more common in older people. It is a leading cause of blindness in people over 60. Many forms of glaucoma have no warning signs. The effect is so gradual that you may not notice a change in vision until the disease is advanced. It is important to have regular eye exams, including measurement of intraocular pressure. Early detection of glaucoma can delay or even prevent vision loss. If you have glaucoma, you will need treatment or lifelong monitoring.
