Glaucoma
Your eye is like a tire: Some pressure inside it is normal and safe. But levels that are too high can damage your optic nerve. Glaucoma is the name for a group of diseases that cause this condition.
A common form is primary open angle glaucoma. Most people who have it don’t have early symptoms or pain. So it's important to keep up with your regular eye exams.
It doesn’t happen often, but glaucoma can be caused by:
An injury to the eye
Blocked blood vessels
Inflammatory disorders of the eye
Treatment includes prescription eye drops or surgery.
