Glaucoma is the second most common cause of blindness in the U.S. There are four major types of glaucoma:

  • Open-angle glaucoma
  • Angle-closure glaucoma, also called closed-angle glaucoma
  • Congenital glaucoma
  • Secondary glaucoma

The front part of the eye is filled with a clear fluid called aqueous humor. This fluid is made in an area behind the colored part of the eye (iris). It leaves the eye through channels where the iris and cornea meet. This area is called the anterior chamber angle, or the angle. The cornea is the clear covering on the front of the eye that covers the iris, pupil, and angle.

Anything that slows or blocks the flow of this fluid will cause pressure to build up in the eye.

  • In open-angle glaucoma, the increase in pressure is often small and slow.
  • In closed-angle, the increase is often high and sudden.
  • Either type can damage the optic nerve.- Medline Plus

“They would either burn or turn my eyes red and inflamed,” she told’s Kara Tsuboi. “We’d keep switching.”

More than 3 million Americans are currently living with glaucoma. It’s one of the leading causes of blindness when left untreated. Finding an effective way to manage the condition can be frustrating. However, a new device barely visible to the naked eye is offering hope to glaucoma patients……See video below
