What is Glaucoma?
Glaucoma is the leading cause of preventable blindness in the U.S. This year, approximately 67 million people worldwide will suffer from glaucoma. Yet, approximately 2 million Americans don't even know they have the disease. Others will be diagnosed only when it's too late to save vision. You see, glaucoma is called the "silent thief of sight" because there is no pain. No noticeable symptoms. And no cure. the good news is glaucoma can be controlled and vision can be preserved if detected early. All you need is vital insight about the health of your eyes to successfully control this disease.

Get insight on the spot. Now there's a fast, comfortable and non-intrusive way to catch glaucoma earlier and track it: the GDX Access or the GDX Nerve Fiber Analyzer. GDX exams provide the earliest possible detection of glaucoma. In fact, GDX is the only glaucoma exam that evaluates the site of damage before you experience any vision loss.

What does GDx show? The result of the GDX exam is a color-coded "thickness map" of the nerve fiber layer at the back of your eye. This provides vital insight that can't be obtained from other exams to help your doctor determine whether you have glaucoma.

Why is GDx used? GDX is used to test for glaucoma and to track the progression of the disease. If your doctor determines you have glaucoma, he or she will continue to use GDX exams to check for damage or changes in your condition. If you do not currently have glaucoma, but are in a risk group for the disease, your doctor may recommend that you be examined today and at regular intervals.

Who is at greatest risk? Glaucoma can affect people of all ages and races. It is the leading cause of blindness in African-Americans. Those at greatest risk include:
