Types of Glaucoma

• Open-angle glaucoma - the most common kind in the USA, about 3 million Americans, many not yet diagnosed.
• Low-tension glaucoma - when open-angle glaucoma occurs with low eye pressure.
• Normal-tension glaucoma - when open-angle glaucoma occurs with normal eye pressure.
• Closed-angle glaucoma - a sudden form of glaucoma that can be a medical emergercy.
• Congenital glaucoma - babies born with eye abnormality leading to glaucoma.
• Secondary glaucoma - can arise from various underlying conditions.
• Pigmentary glaucoma
• Neovascular glaucoma - related to diabetes

Facts About Glaucoma: NEI (Excerpt)

Open-angle glaucoma, the most common form of glaucoma, affects about 3 million Americans--half of whom don't know they have it. It has no symptoms at first. But over the years it can steal your sight. With early treatment, you can often protect your eyes against serious vision loss and blindness. (Source: excerpt from Facts About Glaucoma: NEI)

Facts About Glaucoma: NEI (Excerpt)

Although open-angle glaucoma is the most common form, some people have other forms of the disease.

In low-tension or normal-tension glaucoma, optic nerve damage and narrowed side vision occur unexpectedly in people with normal eye pressure. People with this form of the disease have the same types of treatment as open-angle glaucoma.

In closed-angle glaucoma, the fluid at the front of the eye cannot reach the angle and leave the eye because the angle gets blocked by part of the iris. People with this type of glaucoma have a sudden increase in pressure. Symptoms include severe pain and nausea as well as redness of the eye and blurred vision. This is a medical emergency. The patient needs immediate treatment to improve the flow of fluid. Without treatment, the eye can become blind in as little as one or two days. Usually, prompt laser surgery can clear the blockage and protect sight.

In congenital glaucoma, children are born with defects in the angle of the eye that slow the normal drainage of fluid. Children with this problem usually have obvious symptoms such as cloudy eyes, sensitivity to light, and excessive tearing. Surgery is usually the suggested treatment, because medicines may have unknown effects in infants and be difficult to give to them. The surgery is safe and effective. If surgery is done promptly, these children usually have an excellent chance of having good vision.

Secondary glaucomas can develop as a complication of other medical conditions. They are sometimes associated with eye surgery or advanced cataracts, eye injuries, certain eye tumors, or uveitis (eye inflammation). One type, known as pigmentary glaucoma, occurs when pigment from the iris flakes off and blocks the meshwork, slowing fluid drainage. A severe form, called neovascular glaucoma, is linked to diabetes. Also, corticosteroid drugs—used to treat eye inflammations and other diseases--can trigger glaucoma in a few people. Treatment is with medicines, laser surgery, or conventional surgery. (Source: excerpt from Facts About Glaucoma: NEI)
