Glaucoma is a group of eye conditions that damage the optic nerve, often caused by abnormally high pressure in your eye. It’s one of the leading causes of blindness for people over 60.

The most common type of glaucoma has no warning signs. The effect is so gradual that you may not notice a change in vision until the condition is at an advanced stage.

Regular eye exams that include measurements of your eye pressure are essential for detecting glaucoma early. If glaucoma is recognized early, vision loss can be slowed or prevented.
