An Overview of the Different Types of Glaucoma

October 11, 2016 by Anne Arundel Eye Center

The term Glaucoma actually refers to a group of eye conditions that lead to intraocular pressure (IOP) and damage the optic nerve, the nerve that carries visual information from the eye to the brain. This pressure comes from a buildup of normal fluid called the aqueous humor, which is naturally and continuously produced in the front of your eye.

The different types of glaucoma include:

  • Primary Open-Angle Glaucoma: Affecting around one percent of all Americans (mainly those individuals age 50 or older), it is the most common form of glaucoma. And because this form of glaucoma develops slowly, it rarely ever presents any symptoms and often goes undetected without regular screenings.
  • Normal Tension Glaucoma: Also known as Low-Tension Glaucoma, this form is characterized by progressive optic nerve damage and visual field loss with a statistically normal IOP. The lack of blood flow and the decrease in oxygen to the optic nerve is directly related to this form of glaucoma.
  • Angle-Closure Glaucoma: This form of glaucoma is related to narrow angles. And with several subcategories – including Intermittent and chronic Acute Angle-Closure or Narrow Angle-Closure – this form affects nearly 500,000 Americans, but is most common in people of Asian descent or those individuals with farsightedness (hyperopia). Unlike POAG where the IOP increases gradually, Angle-Closure Glaucoma is characterized by a sudden increase in IOP, often in only a matter of hours. This dramatic increase in IOP can cause severe eye pain, nausea, vomiting, blurry vision and headache. An acute attack is an emergency condition. Long-term effects of Angle-Closure Glaucoma include: scarring of the trabecular meshwork, resulting in chronic glaucoma; cataracts; damage to the optic nerve; permanent vision loss.
  • Pigmentary Glaucoma: This form is a type of inherited open-angle glaucoma, which develops more frequently in men than in women and is most prevalent in individuals in their twenties and thirties. Pigmentary Glaucoma is associated with near-sightedness (myopia).
  • Trauma-Related Glaucoma: A blow to the eye, chemical burn, or penetrating injury may lead to the development of either acute or chronic glaucoma.
  • Childhood Glaucoma: Also referred to as Pediatric Glaucoma, the approach to treatment is slightly different than with glaucoma in adults and almost always requires immediate surgery to relieve IOP. Approximately 80-90 percent of babies who receive prompt surgical treatment, long-term care, and monitoring of their visual development will do well, and may have normal or nearly normal vision for their lifetime. However, if the disease is not caught early more permanent vision loss will result.

The most common symptoms of glaucoma include:

  • Vision loss (most commonly tunnel vision – the gradual loss of peripheral or side vision)
  • Severe eye pain
  • Nausea and vomiting
  • Sudden onset of visual disturbance
  • Blurred or blurry vision
  • Halos around lights
  • Reddening of the eye

If you feel you may be experiencing any of these symptoms, schedule an appointment with your eye doctor immediately. These symptoms are serious and require prompt medical attention from your optometrist or ophthalmologist.

However, many people do not experience any symptoms until they begin to lose their vision. At this point, the damage is irreversible. This is why regular eye exams are so important. While there is no cure for glaucoma, early detection and treatment are your best options to slow or even prevent further vision loss brought on by the disease. Without treatment, glaucoma can lead to permanent vision loss.

Glaucoma is the second-leading cause of vision loss in the United States behind only cataracts.

May is Healthy Vision Month :: Eye Care Tips :: Anne Arundel Eye Center

May 11, 2012 by Anne Arundel Eye Center

Millions of people in the United States alone have undetected vision problems, eye diseases, such as glaucoma, diabetic retinopathy, and age-related macular degeneration (AMD). So in order to raise awareness of this very real problem and promote the importance of proper eye care, early detection and treatment, and eye safety, May was named Healthy Vision Month by the National Eye Institute (NEI) in 2003.

The NEI is one of the National Institutes of Health (NIH), an agency of the U.S. Department of Health and Human Services and the country’s primary medical research agency. The NEI helps develop the federal government’s research on the visual system and eye diseases.

One of the best ways you can protect your vision is to schedule regular checkups with your eye doctor – Ophthalmologist or Optometrist. Your eye doctor will not only evaluate your prescription for eyeglasses or contact lenses, but he/she will also inspect your eyes for common eye diseases and other problems that could lead to vision loss.

Your vision may change as you age, but vision loss is not a normal part of aging. Any loss of vision is a serious medical condition that requires prompt medical attention from your optometrist or ophthalmologist.

The Elderly are at an Increased Risk for Eye Disease

October 28, 2011 by Anne Arundel Eye Center

 In a statement by National Eye Institute Director Paul A. Sieving, M.D., Ph.D., on World Sight Day 2011, the Director urged older Americans to protect their vision. Because, as Sieving explained, older people are simply at an increased risk for eye diseases, including age-related macular degeneration (AMD), Cataracts, Glaucoma, and Diabetic Retinopathy. 

AMD – This eye disease can cause loss of central vision due to the breakdown of the light-sensing cells in the retina.

Cataracts – This eye disease clouds vision because of a clumping of proteins in the eye’s lens.

Glaucoma – This eye disease involves damage to the optic nerve caused by increased intraocular pressure (IOP).

Diabetic Retinopathy – This eye disease impairs vision due to diabetes-related injury to the eye’s blood vessels.

Early stages of these diseases have no symptoms, which is why regular eye exams are crucial to catching eye disease before permanent vision loss occurs. The importance of early detection and treatment of age-related eye disease cannot be overstated.

If you experience a sudden change in vision, such as blurriness/blurry vision, schedule an appointment with your eye doctor immediately. If this change in vision is extreme or if any eye pain is involved, consider having a family member or friend drive you to the emergency room.

Any change in your sight is a serious medical condition that requires immediate attention.

Early Glaucoma Detection:: Anne Arundel Eye Center

September 23, 2011 by Anne Arundel Eye Center

Glaucoma is the second leading cause of vision loss in the United States behind only cataracts. Currently affecting more than 3 million Americans – though half are unaware they even have the eye disease – glaucoma refers to a group of eye conditions that lead to intraocular pressure and damage to the optic nerve, the nerve that carries visual information from the eye to the brain. This pressure comes from a buildup of normal fluid called the aqueous humor, which is naturally and continuously produced in the front of your eye.

Everyone is at risk of glaucoma. However, certain factors can increase that risk, including: if you are over 60 years of age, if you are African American, if you have high myopia (nearsightedness), diabetes, hypertension, or if you need steroids.

To make the situation worse, many people will not experience any symptoms of glaucoma until they begin to lose their vision. The most common type of glaucoma induced vision loss is tunnel vision, the gradual loss of peripheral (side) vision. Other signs and symptoms include: severe eye pain, nausea and vomiting, sudden onset of visual disturbance (often in low light), blurred/blurry vision, halos around lights, and reddening of the eye.

Without treatment, glaucoma can lead to permanent vision loss. While there is currently no cure for glaucoma, regularly scheduled eye exams, early detection, and treatment (medication and possibly surgery) can help slow or even prevent further vision loss brought on by this disease.

Since glaucoma damage begins well before conventional tests can identify it, we are increasingly thankful for the ability to identify early, subtle nerve damage. Doctors are able to utilize advanced imaging devices – special cameras – to create a three dimensional image of the optic nerve, the part of the eye where the eye pressure does its damage. These tests use infra red light or laser light to create a sophisticated computer aided image of the central portion of the optic nerve called the optic cup, and the retinal layer around the nerve, the nerve fiber later, to help predict who might be at risk for vision loss.

These sophisticated early detection devices are helping doctors “predict the future” of glaucoma and intervene long before you have any perceptible loss of visual function.

Besides, Early detection equals earlier, simpler and more effective treatment.

Glaucoma: Finding Out If You Are At Risk

July 22, 2011 by Anne Arundel Eye Center

You may have heard of glaucoma which is a common eye disorder and one of the leading causes of blindness in the United States. But what else do you really know about it and are you at risk?
Glaucoma is an eye disease in which the optic nerve suffers damage and can permanently impair vision in the eye(s). There are different types of glaucoma and the disease can present itself without warning or symptoms. The most common form is the result of elevated pressure of the fluid in the eye and sometimes other factors that cause the fibers running through the optic nerve to slowly deteriorate. Without treatment, glaucoma can lead to permanent vision loss.

Who is at risk?

Everyone is at risk. However, certain factors can increase that risk, including: if you are over 60 years of age, if you are African American, if you have high myopia (nearsightedness), diabetes, hypertension, or if you are a steroid user.

Over 3 million Americans have glaucoma, yet half are unaware that they even have the disease. This is why regular eye exams are so important. While there is no cure for glaucoma, these eye exams, early detection, and treatment (medication and possibly surgery) can help slow or even prevent further vision loss brought on by this disease.

So, when was the last time you had a thorough eye exam?
