Glaucoma Awareness Month

 

January is glaucoma.” There are several types of glaucoma and we are going to provide information about a couple of them courtesy of the Glaucoma Research Foundation! Having an annual eye exam is one of the best ways to know if you have or are developing glaucoma. Knowing what is going on with your eyes is important so get checked regularly.
There are several types of glaucoma. The two main types are open-angle and angle-closure. These are marked by an increase of intraocular pressure (IOP), or pressure inside the eye.
 
Open-Angle Glaucoma:
Open-angle glaucoma, the most common form of glaucoma, accounting for at least 90% of all glaucoma cases:
Is caused by the slow clogging of the drainage canals, resulting in increased eye pressure
Has a wide and open angle between the iris and cornea
Develops slowly and is a lifelong condition
Has symptoms and damage that are not noticed.
“Open-angle” means that the angle where the iris meets the cornea is as wide and open as it should be. Open-angle glaucoma is also called primary or chronic glaucoma. It is the most common type of glaucoma, affecting about three million Americans.
Is caused by blocked drainage canals, resulting in a sudden rise in intraocular pressure
Has a closed or narrow angle between the iris and cornea
Develops very quickly
Has symptoms and damage that are usually very noticeable
Demands immediate medical attention.
It is also called acute glaucoma or narrow-angle glaucoma. Unlike open-angle glaucoma, angle-closure glaucoma is a result of the angle between the iris and cornea closing.
Normal-Tension Glaucoma (NTG):
Also called low-tension or normal-pressure glaucoma. In normal-tension glaucoma the optic nerve is damaged even though the eye pressure is not very high. We still don’t know why some people’s optic nerves are damaged even though they have almost normal pressure levels.
Congenital Glaucoma:
This type of glaucoma occurs in babies when there is incorrect or incomplete development of the eye’s drainage canals during the prenatal period. This is a rare condition that may be inherited. When uncomplicated, microsurgery can often correct the structural defects. Other cases are treated with medication and surgery.
Other Types of Glaucoma:
Variants of open-angle and angle-closure glaucoma include:
Secondary Glaucoma
Pigmentary Glaucoma
Pseudoexfoliative Glaucoma
Traumatic Glaucoma
Neovascular Glaucoma
Irido Corneal Endothelial Syndrome (ICE)
Uveitic Glaucoma
What You Can Do to Manage Your Glaucoma:
By getting informed, staying healthy, and keeping organized, you can establish a routine that works for you.
