It is the second leading cause of blindness in the world. It usually occurs in persons over 40 years old however it can be found at any age. Fortunately loss of sight from glaucoma is often preventable if you get treatment early enough.
High pressure inside the eye is a risk factor for developing glaucoma, although some people with normal eye pressures can develop the disease.
Glaucoma is a disease of the optic nerve, which carries the images that we see from the eye to the brain. The optic nerve is made up of more than one million nerve fibers. The nerve fibers resemble an electric cable containing a large number of wires. Glaucoma can damage these nerve fibers, causing blind spots to develop in your vision.
Usually people with glaucoma will not notice these blind spot areas in their vision until a large amount of the optic nerve has bee damaged. If the entire nerve is destroyed, blindness results.
What Causes Glaucoma?
Clear liquid, called the aqueous humor, circulates inside the eye and is
necessary to keep the eye firm. A small amount of this fluid is produced
constantly, and an equal amount flows out of the eye through a drainage
system located at the angle of the eye. If the drainage angle of the eye is
blocked, excess fluid cannot flow out of the eye and the pressure rises
and this can give rise to glaucoma.
