What Is Glaucoma?

Last updated 6 years ago

Glaucoma refers to a group of eye diseases characterized by progressive vision loss due to optic nerve damage. Studies by the Glaucoma Research Foundation show that approximately 2.2 million Americans currently suffer from glaucoma—while only half of them are aware of their condition. Continue reading to learn more about the causes and symptoms of glaucoma.

Types of Glaucoma:

There are several types of glaucoma, including:

  • Open-angle glaucoma: caused by a clog deep within the drainage canals that results in increased ocular pressure and causes damage to the optic nerve.
  • Angle-closure glaucoma: caused by blocked drainage canals. Angle-closure glaucoma is more common in individuals with narrow angles between their irises and their corneas. As with open-angle glaucoma, angle-closure glaucoma results in increased intraocular pressure, ultimately resulting in damage to the optic nerve.
  • Normal-tension glaucoma: damage to the optic nerve which occurs despite normal intraocular pressure.
  • Congenital glaucoma: develops in babies whose drainage canals were incompletely developed during the prenatal period.

Signs and Symptoms

The signs associated with glaucoma will vary based on the type. For example, individuals suffering from open-angle glaucoma usually do not develop any symptoms until the disease has reached a much more advanced stage. Individuals suffering from angle-closure glaucoma, however, often experience sudden symptoms including blurred or hazy vision, severe eye pain, sudden loss of vision, nausea, and vomiting.

Prevention Tips

There are many steps you can take to help reduce your risk of glaucoma. Consider wearing prescription sunglasses such as Transitions to help protect your eyes from harmful UVA and UVB radiation as this will decrease your risk of glaucoma. Additional ways to reduce your risk of glaucoma include keeping your blood pressure at a normal level, avoiding smoking or other tobacco use, maintaining a healthy diet, and undergoing comprehensive eye exams on a regular basis.
