Glaucoma: The Second Leading Cause of Blindness

glaucoma badgeGlaucoma is a group of diseases that affect the optical nerve which leads to vision loss. While Glaucoma is associated with aging, it is important to remember that Glaucoma can affect anyone at any age and. Glaucoma is generally very slow to progress and therefore many people will only realize they have the disease once a significant amount of vision loss has occurred. Researchers estimate that 50% of people with Glaucoma are unaware that they have the disease. If a close family member had Glaucoma you may be at a 1000% increase in risk and should visit your optometrist for regular eye exams. Estimates are that 3.3 million Americans will have Glaucoma in the year 2020.

The primary reason for Glaucoma leading to blindness is patients not following the directions of their eye doctor in slowing down the progression.

Types Of Glaucoma

Our eyes are extremely complex in how we process what we see. The light passes through the cornea and pupil, it is then focused by the lens, projected to the retina, and then gets sent via the optic nerve to our brain. In a patient with Glaucoma, the optic nerve is under pressure which causes some of the images to get lost or distorted.

For people aged 40-55 an eye exam should be done every 1-3 years (more often if you have any other risk factors), 55-64 an eye exam should be done every 1-2 years, and for people 65 and over every 6-12 months.

There are two primary types of Glaucoma:

Open Angle Glaucoma is the most common form and consists of different variations primary open angle glaucoma, pigmentary glaucoma, normal-tension glaucoma, secondary glaucoma and congenital glaucoma, pseudoexfoliation glaucoma. In this type of Glaucoma fluid in your eye does not drain properly which places pressure on the optic nerve.

Angle-closure glaucoma is a less common form of Glaucoma in the United States. In this type of Glaucoma the angle of the Iris does not allow for proper draining of fluid in your eyes which results in build up of pressure.

Who Is At Risk For Glaucoma?

There are increased risk of Glaucoma for any person who is:

    • A close relative of someone with Glaucoma.
    • At higher risk of eye disease such
      as having diabetes.
    • Over the age of 40.
    • Suffers from migraine headaches, obesity, or high blood pressure.
    • African American's are at 3 times more risk of Glaucoma.
    • Recent research has shown that people of Filipino ancestry are at increased risk of Glaucoma.
    • People from Irish, Russian, Japanese, Hispanic, Inuit, and Scandinavian are at higher risk.

What Are The Treatment Options For Glaucoma?

The primary method of treatment for Glaucoma is to manage the disease and prevent vision loss. In most cases either eye drops or pills will be prescribed which lower the pressure in your eye.

In some cases where medication will not provide the needed slow down of progression, your eye doctor may recommend surgery.

Because Glaucoma is often not detected before significant irreversible damage has occurred, the best prevention is regular eye exams.

Research has shown that exercise is effective at lowering the risk profile for Glaucoma.

Four Key Facts About Glaucoma

1. Glaucoma is a leading cause of blindness

Glaucoma can cause blindness if it is left untreated. And unfortunately approximately 10% of people with glaucoma who receive proper treatment still experience loss of vision.

2. There is no cure (yet) for glaucoma

Glaucoma is not curable, and vision lost cannot be regained. With medication and/or surgery, it is possible to halt further loss of vision. Since open-angle glaucoma is a chronic condition, it must be monitored for life. Diagnosis is the first step to preserving your vision.

3. Everyone is at risk for glaucoma

Everyone is at risk for glaucoma from babies to senior citizens. Older people are at a higher risk for glaucoma but babies can be born with glaucoma (approximately 1 out of every 10,000 babies born in the United States). Young adults can get glaucoma, too. African Americans, in particular, are susceptible at a younger age.

4. There may be no symptoms to warn you

With open-angle glaucoma, the most common form, there are virtually no symptoms. Usually, no pain is associated with increased eye pressure. Vision loss begins with peripheral or side vision. You may compensate for this unconsciously by turning your head to the side, and may not notice anything until significant vision is lost. The best way to protect your sight from glaucoma is to get tested. If you have glaucoma, treatment can begin immediately.

Some Statistics About Glaucoma

Sources are listed at the bottom of this page.

  • It is estimated that over 3 million Americans have glaucoma but only half of those know they have it. 
  • In the U.S., more than 120,000 are blind from glaucoma, accounting for 9% to 12% of all cases of blindness.
  • Glaucoma is the second leading cause of blindness in the world, according to the World Health Organization.
  • After cataracts, glaucoma is the leading cause of blindness among African Americans. 
  • Blindness from glaucoma is 6 to 8 times more common in African Americans than Caucasians. 
  • African Americans are 15 times more likely to be visually impaired from glaucoma than Caucasians. 
  • The most common form, open-angle glaucoma, accounts for 19% of all blindness among African Americans compared to 6% in Caucasians. 
  • Other high-risk groups include people over 60, family members of those already diagnosed, diabetics, and people who are severely nearsighted.
  • Estimates put the total number of suspected cases of glaucoma at over 60 million worldwide. 
Public Awareness and Attitudes

A survey done for the Glaucoma Research Foundation found that:

  • 74% of over 1,000 people interviewed said they have their eyes examined at least every two years.
  • 61% of those (less than half of all adult Americans) are receiving a dilated eye exam (the best and most effective way to detect glaucoma).
  • 16% of African Americans were unfamiliar with glaucoma.
  • 9% of Caucasians were unfamiliar with glaucoma.

A 2002 Prevent Blindness America Survey found that:

  • Blindness ranked third (after cancer and heart disease) as people's major fear.
  • 20% of people knew that glaucoma was related to elevated pressure within the eye. Most of them mistakenly thought people could tell if they had glaucoma due to symptoms, or that it was easily cured, or that it did not lead to blindness.
  • 50% had heard of glaucoma but weren't sure what it was.
  • 30% had never heard of glaucoma.
Economic Impact
  • Glaucoma accounts for over 10 million visits to physicians each year. (7)
  • In terms of Social Security benefits, lost income tax revenues, and health care expenditures, the cost to the U.S. government is estimated to be over $1.5 billion annually.
