Glaucoma is a condition where excessive pressure in your eye damages your optic nerve. It’s one of the leading causes of blindness in America today.
The two most common forms of glaucoma are open-angle and closed-angle. They get their name from the condition of the drainage angles in your eyes. The drainage angles are located between your iris and your cornea and allow excess fluid to escape your eye. When your eye fluid doesn’t drain properly, it accumulates and increases the pressure in your eye, eventually damaging your optic nerve.
