Glaucoma is a group of eye conditions (typically classified as open- or closed-angle, and primary or secondary) characterized by progressive damage to the optic nerve head. Because the optic nerve transmits visual information from the eye to the brain, glaucoma can lead to vision problems if not treated early, and can eventually cause irreversible vision loss if left untreated.[1]
