A visual field test is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, brain tumours or other neurological deficits.
The exam may be performed by a technician in one of several ways. The test may be performed by a technician directly, with the assistance of a machine, or completely by an automated machine. Machine based tests aid diagnostics by allowing a detailed printout of the patient's visual field.
Other names for this test may include Perimetry, Tangent screen exam, Automated perimetry exam, Goldmann visual field exam, or Humphrey field exam.

—Edward Dahlberg (1900–1977)
“The face we see was never young,
Nor could it ever have been old.
For he, to whom we had applied
Our shopman’s test of age and worth,
Was elemental when he died,
As he was ancient at his birth:”
—Edwin Arlington Robinson (1869–1935)
