The Purpose Of Visual Field Testing, Or Perimetry, Is To Provide Information Critical To:

-Diagnosing Ocular Diseases, Especially Glaucoma

-Evaluating Neurological Diseases

-Monitoring The Progress Of Ocular And Neurological Diseases


Visual field testing can lead to early detection and treatment of disease. In the case of glaucoma, visual fields play a major role in identifying visual field defects and evaluating the efficacy of the therapy used to control the disease process.

When evaluating visual performance, clinicians are primarily interested in two retinal tests measure functions: resolution and contrast sensitivity. Resolution is the ability to identify discrete forms (letters, numbers, symbols), and is commonly measured with the visual acuity test. Resolution rapidly diminishes with increasing distance from the fovea and is, therefore, a poor indicator of overall visual performance.

A better means of evaluating visual function—especially those areas less sensitive than the fovea—is contrast sensitivity testing. Contrast sensitivity is the ability to detect a stimulus (spot of light or other target) against a darker or brighter background. Standard Humphrey perimetry may be thought of as contrast sensitivity testing applied throughout the peripheral visual field.

In perimetry, the term “threshold” is used to describe a very specific level of stimulus detection. The threshold represents the point at which a stimulus is seen 50% of the time and missed 50% of the time. The assumption is that all stimuli brighter than the threshold value will be seen and all stimuli dimmer will be missed. Reviewing the threshold value at each point tested in the visual field is an important part of the diagnostic process.

Visual field tests can yield information that is general in nature, as with screening tests, or more exacting and quantitative, as with threshold tests. In deciding which test type is most appropriate for a patient the practitioner is influenced by many factors, including the patient’s presenting complaint, family history, age, degree of cooperation, and time available to run the test.
