Goldmann perimeter. The Goldmann perimeter is a hollow white spherical bowl positioned a set distance in front of the patient.

An examiner presents a test light of variable size and intensity. The light may move towards the center from the perimeter (kinetic perimetry), or it may remain in one location (static perimetry).

The Goldmann method is able to test the entire range of peripheral vision, and has been used for years to follow vision changes in glaucoma patients.

However, now automated perimetry is more commonly used.
