A glaucoma is a group of diseases that causes changes in the optic nerve that can lead to temporary vision loss or blindness. With this condition, it is best that you get a glaucoma evaluation especially if you have a family history of glaucoma.

Glaucoma is a condition in the eye where the optic nerve is damaged from fluid build-up. The fluid builds up in the front part of the eye, gradually damaging the optic nerve by the pressure caused by the fluids on the eye. Glaucoma is the second leading cause of blindness, next to Cataracts. If left untreated it can lead to permanent and irreversible loss of vision.

There are many forms of glaucoma, but most have no warning signs. The effect is so gradual that you won’t notice any of the symptoms until it is at an advanced stage. Vision loss due to glaucoma is irreversible, so having a regular eye exam can help in diagnosing this condition early so you can start with the treatment immediately.


The two main types of glaucoma are Open-angle and Angle-closure. But there are eight additional types of glaucoma, which are a variation of the two main types. These glaucoma types can occur in either or both eyes.



· Open-Angle Glaucoma

Also often called Primary Open-Angle Glaucoma, this is the most common form of glaucoma. This is a lifelong condition that makes up to 90% of glaucoma cases.

This condition happens because the eye’s drainage canal becomes clogged over time. The inner eye pressure rises because the fluid can’t be drained out of the eye. With open-angle glaucoma, the drainage canals would seem to be working perfectly but the problem occurs further down as it is clogged inside.


· Angle-Closure Glaucoma

Also known as Primary Angle-Closure Glaucoma, or Narrow-Angle Glaucoma. This condition happens because almost all the angles between the iris and cornea is closed, reducing the drainage of the eye fluid and can cause increase in the eye pressure.

This type requires immediate medical attention. The flow of your aqueous fluid is blocked, a rapid buildup of fluid will cause severe and painful pressure in your eyes. With this condition, the iris is not as wide and as open as it should be.


· Normal-Tension Glaucoma

Also known as Low-Tension Glaucoma. In this condition, damage occurs in the optic nerve even though there is no high pressure in the eyes.

A debate among the glaucoma experts have ensued whether normal-tension glaucoma is different from open-angle glaucoma. But due to further research, it appears that that there are features more common in normal-tension glaucoma patients than in open-

angle glaucoma patients. Patients with normal-tension glaucoma have visual field abnormalities that are close to the center of vision. They also have hemorrhages in the small blood vessels of the optic nerve, and they tend to have migraines and low blood pressure.


Secondary Glaucoma

This is the type of glaucoma that has an identifiable cause for the increased eye pressure that results to nerve damage. Sometimes, this type of glaucoma can also be caused by other medical condition. There are several sub-types of secondary glaucoma, which includes:

· Neovascular glaucoma – caused by the extra blood vessels made by the eyes that covers part of the eye where fluid normally drain

· Pigmentary glaucoma – this condition happens when the color of the iris flakes off and blocks the fluid from draining

· Exfoliative glaucoma – this happens when a dandruff-life material is noticed to peels off from the outer layer of the lens within the eye

· Neovascular glaucoma – this is caused by the strange formation of new blood vessels on the iris and above the drainage channels of the eye

· Traumatic glaucoma – this type of glaucoma happens after the eye has been injured. This is a form of open-angle glaucoma that can develop years after an injury to the eye

· Congenital glaucoma – this occurs in babies that has an incomplete development of the eye’s drainage canals during prenatal period

· Uveitic glaucoma – uveitis means swelling and inflammation of the uvea, or the middle layer of the eye. The increased pressure of the eye can cause the inflammation
