In congenital glaucoma, babies are born with a problem in their eye that makes fluid drain more slowly than normal. Angle-closure glaucoma: The iris bulges toward the front of the eye, blocking the drainage angle formed by the cornea and iris.

The most common type is open-angle (wide angle, chronic simple) glaucoma, in which the drainage angle for fluid within the eye remains open, with less common types including closed-angle (narrow angle, acute congestive) glaucoma and normal-tension glaucoma. It can end up damaging both the optic nerve and the retina. Most cases are caused by a build-up of pressure in the eye when fluid is unable to drain properly.
