Open Angle Glaucoma

How Is It Diagnosed?

Many people may know of the "air puff" test or other tests used to measure eye pressure during an eye examination. However, this test alone cannot detect open angle glaucoma; while elevated eye pressure means that you are at risk for developing the condition, it does not necessarily mean that you have it (see Glaucoma and Eye Pressure). A person has glaucoma only if the optic nerve is damaged. If you have increased eye pressure but no damage to the optic nerve, you do not have open angle glaucoma.
 
A diagnosis is most often made through a comprehensive eye exam that includes the following:
 
  • Visual acuity test
  • Visual field test
  • Dilated eye exam
  • Tonometry
  • Pachymetry.

Treatment Options for Open Angle Glaucoma

Although there is no cure for open angle glaucoma, symptoms can usually be controlled. The most common treatments are:
 
Medications
Glaucoma medications are availabe in the form of pills or eyedrops. Some drugs are designed to reduce pressure by slowing down the flow of fluid into the eye. Others help to improve fluid drainage.
 
For most people with open angle glaucoma, regular use of medications will control the increased fluid pressure. However, these drugs may stop working over time. They may also cause some side effects. If a problem occurs, your eye care professional may select other glaucoma medications, change the dosage, or suggest other ways to handle the problem.
