Glaucoma is a disease in which the pressure in the eye leads to optic nerve damage. The optic nerve is what carries light signals from the eye to the brain. Damage to the optic nerve can lead to blindness. 3 million Americans are estimated to have glaucoma, and half of the patients with glaucoma do not realize they have the disease. There are generally no symptoms in the early stages. The loss of vision can be gradual, which makes glaucoma a silent disease. If left untreated, blindness may occur. Fortunately, there are glaucoma treatments to help prevent vision loss.
The most common types of Glaucoma are:
- Open-Angle Glaucoma
- Closed-Angle Glaucoma (Narrow-Angle or Angle-Closure)
- Secondary Glaucoma
