Closed-angle glaucoma is more common in women. Glaucoma has been called the silent thief of sight because the loss of vision usually occurs slowly over a long period of time. Worldwide, glaucoma is the second-leading cause of blindness after cataracts.
Glaucoma is characterized by damage to the optic nerve, resulting in unrelieved pressure inside the eye and fluid buildup. The cause is unknown but is probably genetic. Permanent impairment can range from loss of peripheral vision to severe vision loss.
