If dedicated machinery is used during a field test, the test is referred to as a perimeter. Other names for this exam: perimetry, Automated perimetry exam, Tangent screen exam, Humphrey field exam or Goldmann visual field exam. A field test may be carried out directly by a technician, with help from a machine or entirely by a machine that is automated.
