Understanding glaucoma

Glaucoma is a common eye disease that occurs due to increased pressure in the eye caused by a buildup of excess fluid. The most common form of glaucoma is called primary open-angle glaucoma (POAG), which typically does not have warning signs.

Healthy eye

In a healthy eye, a fluid called aqueous humor flows freely throughout the eye and travels through an internal drainage system.

Glaucoma

If the drainage system is blocked or partially obstructed, the natural pressure in your eye may increase. When eye pressure becomes too high, the optic nerve can become damaged causing blurred vision, severe eye and head pain, and, if left untreated, vision loss or blindness.

Glaucoma facts

  • The #1 leading cause of irreversible vision loss1
  • The 2nd leading cause of global blindness2
  • Nearly 80 million people worldwide suffer from glaucoma (the majority go undiagnosed)2
  • More than 4 million Americans age 40+ have primary open-angle glaucoma2

Risk factors for glaucoma

Managing glaucoma

The best way to protect your sight from glaucoma is to get a comprehensive eye exam. Currently, there is no cure for glaucoma. However, preventative methods can be used to slow or even stop further vision loss with early detection, medication, minimally invasive glaucoma surgery, or if required more invasive surgical techniques.

If you have mild to moderate primary open-angle glaucoma, ask your doctor about your treatment options including the Hydrus Microstent.
