What is Glaucoma?


Glaucoma isn’t one disease. Instead, it’s a group of diseases that cause damage to the optic nerve. In most cases, this damage is the result of increased pressure within your eye. As the optic nerve deteriorates, the patient gradually loses the ability to see to the side (peripheral vision). In time your central vision may begin to decrease as well. If glaucoma isn’t treated, it eventually may lead to total blindness.
In fact, glaucoma is the second most common cause of blindness. That’s because glaucoma often gives no warning sign until permanent damage has already occurred. In most cases the onset is so gradual you’re not aware you’ve lost some of your peripheral vision.
