The visual field test is among the most important tests to learn to interpret as you begin your career in ophthalmology. Learn about the top 5 most common fields!

The Esterman Visual Field Test is carried out on both eyes together (binocularly) and wearing any glasses that you normally wear when driving. It is carried out on a visual field analyser, a computerised machine where you have to responding to small, flashing lights by pressing a button whilst looking straight ahead. Interpreting the Goldmann field test. The key to interpreting Goldmann visual fields is to keep in mind the normal hill of vision ( figure 1) and how it compares with the patient's results. The skill is in identifying patterns and observing any change with repeated tests. The EyeLab Simulated Esterman Visual Field Test EVFT. You must have a horizontal visual field of at least 160 degrees, the extension should be at least 70 degrees left and right and 30 degrees up and down.

For accurate visual field test results, correct the patient to within the refractive error cited in the table below. Verify that the patient's eyes are not dilated during the 

Esterman visual field perimetry is a binocular testing method which is also available on the HFA. The test consists of 120 white test points shown with equal, non-adjustable suprathreshold light intensity of 10 dB and examines more than 130° of the field. The Esterman tests a total field extent that approximates 145 degrees rather than “extends to 160 degrees temporally on both sides.” The Esterman tests (both binocular and monocular) use the same stimulus intensity as the other Humphrey screening tests, which would obviously differ from a threshold test. A visual field test is a way to measure your entire visual field—the range of what you can see above, below, and on either side of you while your gaze is fixed on a central point directly in front of you. It can identify scotomas, or blind spots, as well as loss of peripheral (side) vision that is an indicator of glaucoma. A visual field test can determine if you have blind spots (called scotoma) in your vision and where they are. A scotoma’s size and shape can show how eye disease or a brain disorder is affecting your vision.

At Gilroy Opticians in Belfast, we can carry out the test and provide you with the required paperwork and can have a look at your prescription if necessary. Visual field tests measure the total area that is seen while the eye is directed straight ahead. The total visual field with both eyes open is approximately 180° horizontally and 155° vertically. A visual field of less than 60° will start to significantly impact on a person’s ability to move about within the environment. The Octopus 900 performs standard white-on-white threshold testing in just 2–4 minutes in the central visual field. With its comprehensive test library for central and peripheral tests and its flexible printouts both in Octopus and HFA-format it covers all your clinical needs. Machine based tests aid diagnostics by allowing a detailed printout of the patient's visual field.

an interpretation of the results, with report; the impact on treatment and prognosis; your signature. As of July 1, 2001, Medicare's supervision rules for many diagnostic tests changed. Visual fields now require only general supervision, which means that your presence isn't required when your employee performs the test in your office.
