Glaucoma is a group of eye diseases that damage the optic nerve at the back of your eye. This can cause vision loss. Although the cause of glaucoma isn't clear, experts think it's often related to a buildup of pressure in the eye.

Glaucoma can be easily detected during regular eye exams. It usually responds well to treatment with medicine.
