Open-angle glaucoma It’s the most common type. Your doctor may also call it wide-angle glaucoma. The drain structure in your eye -- it’s called the trabecular meshwork -- looks normal, but fluid doesn’t flow out like it should.

Angle-closure glaucoma It’s less common in the West than in Asia. You may also hear it called acute or chronic angle-closure or narrow-angle glaucoma. Your eye doesn’t drain right because the drain space between your iris and cornea becomes too narrow. This can cause a sudden buildup of pressure in your eye. It’s also linked to farsightedness and cataracts, a clouding of the lens inside your eye.
