Glaucoma is a leading cause of blindness, affecting millions of people worldwide. It is a condition that damages the optic nerve, the nerve that carries visual information from the eye to the brain.

It is important to see your ophthalmologist (eye doctor) for regular checkups to monitor your eye pressure and to discuss your treatment options.
