What Is Glaucoma?
Glaucoma is actually a group of diseases that damage the eye’s optic nerve and can result in vision loss and even blindness. In fact, it’s the leading cause of blindness in the United States. There is no cure for glaucoma. However with early detection and treatment, we can protect our eyes from vision loss.
Eye pressure (called intraocular pressure or “IOP”) is a major risk factor for optic nerve damage. In the anterior chamber (a space in the front of the eye), a clear fluid flows continuously in and out of the chamber. The fluid leaves the chamber at the open-angle where the cornea and iris meet and drains out of the eye.
In what is called “open-angle glaucoma”, the fluid passes too slowly which builds pressure in the eye to a level that it may damage the optic nerve. That’s why controlling pressure inside the eye is important.
