Glaucoma is a disease that affects the optic nerve. The disease causes optic nerve damage, which leads to partial or total vision loss. These two types of glaucoma both stem from a problem in the angle between the cornea and iris of the eye. They are called Narrow Angle and Closed Angle Glaucoma.

Narrow Angle glaucoma can develop either quickly or slowly and usually occurs in people with farsightedness. It occurs when the angle narrows causing the aqueous fluid to build up. This narrowing is caused by a bowing of the iris. Narrow Angle glaucoma can only be detected through routine eye examinations. It can cause vision loss and can also lead to an emergency condition called closed angle glaucoma.

Closed angle glaucoma, also called angle closure glaucoma, develops quickly and is a medical emergency. It occurs when the iris bows forward so much that the angle is completely closed. That means that no aqueous fluid can escape, which causes the pressure to build up rapidly. There...

Glaucoma is a disease that affects the optic nerve. The disease causes the nerve cells at the front of the optic nerve to die, which leads to partial or total vision loss. The first two types of glaucoma occur with in an eye that has no structural deformities. They are called Open Angle and Normal Tension Glaucoma.

Open Angle glaucoma, also referred to as chronic glaucoma, normally develops after the age of 35 and is the most common form of glaucoma. It occurs when aqueous fluid builds up and causes the pressure inside your eye to increase. The fluid is not drained properly because of a clog in the trabecular meshwork, a sponge-like, porous tissue which drains fluid from the eye. This happens gradually, with no symptoms. It can lead to partial or total vision loss and can only be detected through routine eye examinations.

The second type of glaucoma affects a small percentage of people and is called Normal Tension glaucoma. It occurs with normal eye pressure and can be...
