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.

National Glaucoma Awareness Month

January 24, 2012 by Anne Arundel Eye Center

Glaucoma refers to a group of eye conditions that lead to damage the optic nerve, usually resulting from a rise in intraocular pressure (IOP). The optic nerve carries visual information from the eye to the brain.

Over 60 million people worldwide (2.2 million Americans) have glaucoma and experts estimate that nearly half of them are unaware they are currently affected by the disease. This is probably because glaucoma displays no symptoms and, at first, only affects peripheral or side vision. As a result, an individual can lose as much as 40% of their vision before even noticing. This is also why glaucoma has been nicknamed “the sneak thief of sight.”

Once a person begins to lose their vision, 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 early detection and treatment, glaucoma can lead to permanent vision loss. In fact, glaucoma is the second-leading cause of vision loss in the United States behind only cataracts.

This is why January has been named National Glaucoma Awareness Month.

You are at an increased risk developing glaucoma if…

•You are of African, Asian, and Hispanic descent

• You are over the age of 60

•You have a family member who has already been diagnosed

• You are diabetic

•You are severely nearsighted (myopic)

While everyone should have their eyes examined regularly, those with the above risk factors should increase the frequencies of those examinations.

Early detection equals earlier, simpler and more effective treatment.

Prevent an Eye Emergency Around Chemicals and Construction by Wearing Goggles

November 17, 2011 by Anne Arundel Eye Center

Eye injuries in the workplace are much more common than you may think. The National Institute for Occupational Safety and Health (NIOSH) reports about 2,000 job-related eye injuries that require medical treatment every day. That is just in the United States, alone. And of those 2,000 occupational eye injuries, eye doctors believe that an incredible 90% could have been prevented with the use of proper eye protection. Because of this, the Occupational and Health Administration (OSHA) requires the use of protective eyewear – goggles, face shields, safety glasses, or full-face respirators – whenever there is a reasonable probability of eye injury.

Proper eye protection differs depending on the specific situation and eye hazards present.

•      Safety glasses with side shields should be worn in situations where foreign objects – dust, dirt, sawdust, etc. – will be flying around.

•      Goggles should be worn whenever you are working with chemicals

•      Specially made safety glasses, goggles, face shields, or helmets should be worn near hazardous radiation

If you have any questions about eyewear, consult your eye doctor – optometrist or ophthalmologist. They should be able to help you determine what type of eye protection you need. You should always wear appropriate eye protection wherever and whenever there is any sort of threat of eye injury, especially at work.

High-risk occupations for eye injuries include:

•      Construction

•      Manufacturing

•      Carpentry

•      Auto Repair

•      Electrical Work

•      Plumbing

•      Welding

•      Maintenance

If you experience any eye injury, even if it seems minor, call your eye doctor immediately to schedule an eye exam or have a friend or family member drive you to the emergency room. Eye injuries are serious and require prompt medical attention from your optometrist or ophthalmologist.
