Types of Glaucoma

Types of GlaucomaPrimary Open Angle Glaucoma

  • The most common form of glaucoma in the U.S.
  • No early warning signs, often called the"silent thief of sight”
  • Can occur with high or normal eye pressures
  • Optic nerve damage results in vision loss

Angle-Closure Glaucoma

  • Can cause a sudden and severe rise in eye pressure
  • Occurs when the eye drainage canal is blocked by the iris
  • Can be either acute or chronic
  • Acute episodes can result in severe pain

Symptoms and Risk Factors

Early Stage Glaucoma is very hard to detect and usually goes unnoticed by patients until their optical nerves are very damaged. Only a complete eye examination through dilated pupils along with other specialized testing can diagnose the disease in the early stages. The hallmark of glaucoma is the lack of symptoms until the disease is very advanced.

Major risk factors for Glaucoma include:

  • A family history of glaucoma
  • Age (55 or older)
  • Black or Hispanic Nationalities
  • Extreme nearsightedness (distant objects are very blurry)
  • A history of high pressure in your eyes
  • History of eye trauma
  • Prolonged use of steroids
  • Sleep apnea
