Glaucoma is a disease of the eye that causes progressive damage to the optic nerve, which can lead to vision loss and even blindness. There are different types of glaucoma, each of which is related to pressure inside the eye. Most of the time, glaucoma develops later in life, however, it is possible to affect people at any age. The vision loss from glaucoma is permanent and it is one of the leading causes of blindness for people over the age of 60.
Many forms of glaucoma have no early signs or symptoms, which makes screening eye exams especially important in helping to prevent visual decline. With early recognition, glaucomatous damage can be slowed or stopped, but the disease often requires lifelong monitoring and treatment.
Every eye is filled with a fluid called aqueous humor. This fluid is constantly being produced by the eye and it drains back into the body’s bloodstream to maintain normal eye pressure. If there is a blockage of fluid drainage, the pressure in the eye builds up and can result in glaucoma. While some forms of glaucoma are inherited, most of the time the etiology is unknown. Less common causes include blunt or chemical injury to the eye, severe eye infections, blocked blood vessels in the eye, inflammatory eye diseases, and certain medications.
Signs and symptoms vary depending on the type and stage of the condition. When symptoms do develop, it is usually late in the disease. If you have any of the following symptoms, get medical care right away:
