It is Glaucoma Week. As a result, this week’s blog will feature three facts you should know about glaucoma.
What is glaucoma?
Glaucoma is a progressive disease of the optic nerve that can lead to vision loss or blindness. The optic nerve is a bundle of over one million nerve fibers that transports our visual information from the eye to the back of the brain where it is processed. In the early stages of glaucoma, there are often no visual symptoms. This has led to it being called “the silent thief of sight”. Studies have shown that up to half of the nerve tissue needs to be damaged before changes are noted in one’s vision. Unfortunately, once damage occurs, it is permanent. Thus, early detection is critical to preserving one’s vision. A dilated eye exam is critical to early detection. Some studies show that as many as 50% of those with glaucoma are unaware that they have glaucoma.
