Open–angle glaucoma is the most common type. In open–angle glaucoma an imbalance develops between the production of eye fluid and the rate at which it drains, thus producing higher pressure than the eye can tolerate. Patients usually do not have any symptoms such as blurred vision, red eye, or pain. Open–angle glaucoma generally develops over a period of time and is usually detected during a routine eye exam.

2 million Americans are visually impaired by glaucoma; 1 million more have the disease but don’t know it.

Those particularly at risk for open-angle glaucoma are…

  • People of African heritage
  • Patients with diabetes or high blood pressure

  • Patients with a family history of glaucoma

  • Older people

  • Those who’ve suffered past eye injuries
