Why Do You Need A Visual Field Test

Function Of A Visual Field Test

Visual Field tests are a fundamental part of assessing eye health. The purpose of a Visual Field test is to measure a patient’s central and peripheral vision. These results provide necessary information to our doctors, to help diagnose and monitor numerous conditions.

Who Should Get A VF Test

Examination of one’s visual field is an important part of regular eye care, especially for those who are at a higher risk of vision loss due to underlying diseases or conditions. People with the following conditions should be monitored regularly due to their heightened risk of vision loss:  

  • Glaucoma
  • Age-Related Macular Degeneration
  • Multiple sclerosis
  • Thyroid eye disease
  • Pituitary gland disorders
  • Central nervous system problems (such as a tumor pressing on the brain)
  • Stroke
  • Long-term use of certain medications
People with diabetes or high blood pressure have an increased risk of developing blocked blood vessels in the optic nerve and retina. Regular appointments with your ophthalmologist accompanied by visual field tests can help identify any problems or potential risks. Visual Field tests allow our doctors to identify and address these issues before serious damage can occur.

VF Tests At Fraser Valley Cataract & Laser

Visual Field tests are subjective. The test relies on a patient’s cooperation and ability to respond to prompts the test gives them. For this reason, our technicians at Fraser Valley Cataract and Laser are constantly monitoring patients throughout the duration of the test. This ensures that doctors are presented with the most reliable information on the patient’s eye health. There are certain guidelines that must be followed ie: the patient must not be moving their head, their chin, they can not be looking around, etc. If the guidelines are not followed it invalidates the test results necessitating the re-administering of the test.
