Glaucoma is a group of eye diseases that damages your eye’s optic nerve. It usually happens when fluid builds up in the front part of your eye. That extra fluid increases the pressure in your eye, damaging the optic nerve.

Please keep in mind that early glaucoma usually has no symptoms, therefore, routine eye exams are critical in the prevention of the disease. If left untreated, glaucoma initially causes loss of peripheral vision and can eventually lead to blindness.
