4 Important Points that Help Triangle Patients Understand Glaucoma

Glaucoma is a devious eye disease that does much of its damage before the patient notices vision loss. However, with early diagnosis, patients can begin treatments to manage the disease. The Triangle area is fortunate to have Ophthalmologist Dr. Beth R. Friedland, who takes a special interest in the treatment of Glaucoma.

January is Glaucoma Awareness Month so Park Ophthalmology in Durham and Raleigh wants to share important facts about this serious eye condition.

The Park Ophthalmology Team offers four important points to help everyone to better understand Glaucoma:

  • By the numbers: The American Academy of Ophthalmology estimates that more than three million Americans have glaucoma, but only half of them are aware of it. In the United States, it is the fourth leading cause of vision loss, after age-related macular degeneration, cataracts and diabetic retinopathy.
  • Optic nerve damage: Glaucoma damages the optic nerve at the back of the eye. This nerve transmits images to the brain, creating vision. With Glaucoma, irreversible damage can occur before the patient is aware of sight loss. It is sometimes called the “sneak thief of sight.”
  • Eye pressures: The common cause of glaucoma is a rise in internal eye pressure, which damages the optic nerve. Eyes need the right amount of fluid pressure to retain their shape, but sometimes the eyes produce too much or drainage routes become obstructed. Once diagnosed, patients must have their eye pressures monitored closely by Dr. Friedland.
  • Two types: There are two types of Glaucoma – narrow-angle and primary open-angle – and patients experience them in different ways. Narrow-angle Glaucoma often occurs suddenly and causes eye pain, vision loss, nausea or halos, symptoms that prompt patients to see an ophthalmologist. By contrast, primary open-angle Glaucoma develops slowly with no obvious symptoms. Patients’ first awareness of a problem likely will be a loss of peripheral vision.
