Glaucoma is not just one eye disease, but a group of eye conditions resulting in optic nerve
damage, which may cause loss of vision. Abnormally high pressure inside your eye (intraocular
pressure) usually, but not always, causes this damage.
Glaucoma is one of the leading causes of blindness in the United States. Glaucoma can damage
your vision so gradually you may not notice any loss of vision until the disease is at an advanced
stage. The most common type of glaucoma, primary open-angle glaucoma, has no noticeable
signs or symptoms except gradual vision loss.
Early diagnosis and treatment can minimize or prevent optic nerve damage and limit glaucomarelated vision loss. It’s important to get your eyes examined regularly, and make sure your eye
doctor measures your intraocular pressure.
