Open Angle Glaucoma

Causes and Risk Factors

Open angle glaucoma is one of the leading causes of blindness in the United States. However, glaucoma research scientists are not sure of the exact cause or causes of this disease. They do know that although anyone can get the condition, some people are at higher risk. People who are at higher risk for open angle glaucoma include:
  • African Americans over age 40
  • Everyone over age 60, especially Mexican Americans
  • People with a family history of glaucoma
  • People with diabetes.
Among African Americans, studies show that open angle glaucoma is:
  • Five times more likely to occur than in Caucasians
  • About four times more likely to cause than in Caucasians
  • Fifteen times more likely to cause blindness in African Americans between the ages of 45 and 64 than in Caucasians of the same age group.

Symptoms of Open Angle Glaucoma

There are usually no early symptoms of open angle glaucoma. There is no pain, and vision stays normal. However, as the disease progresses, a person may notice the following symptoms:
  • Gradually failure of side vision (objects in front may be clear, but objects to the side may be missed)
  • Narrowed vision
  • Blindness.
These symptoms are not sure signs of glaucoma. Other eye problems can also cause these symptoms. Anyone experiencing these problems should see an eye care professional for proper diagnosis and treatment.
