The Goldmann perimeter is a hollow white spherical bowl positioned a set distance in front of the patient. [3] 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).
Meridian (plural: "meridians") is used in perimetry and in specifying visual fields. According to IPS Perimetry Standards 1978 (2002): " Perimetry is the measurement of [an observer's] visual functions ... at topographically defined loci in the visual field.

Goldmann Applanation Tonometer attached with Slit lamp biomicroscope Goldmann Applanation Tonometer is an instrument that is based on Imbert-Fick law . It is considered to be the gold standard instrument for measurement of Intraocular pressure (IOP).
It is combined with a visual field test such as standard automated perimetry (SAP) or short wavelength automated perimetry (SWAP) to determine visual fields in a more efficient manner. Standard automated perimetry determines how dim of light (the threshold) can be seen at various points in an individual eye's visual field.
Goldmann's perimeter (1945 development), [4] Goldmann's tonometer, [4] Goldmann's indirect goniolens, Goldmann-Weekers Dark Adaptometer™, [5] and; fluorophotometer.
