Skilled manual kinetic and static threshold perimetry is assumed to be the standard of practice. However, Trobe suggested that the actual standard in clinical practice may fall considerably short of this ideal [3]. We polled the ophthalmologists in the state of Kentucky.

In static perimetry the method of limits is widely used for threshold determinations. Its performance is compared with that of a certain modification of the staircase method (repetitive up and down method) by means of simulations, where the behaviour of the observer is described by an assumed psychometric function.

Abstract A large absolute paracentral ring scotoma was found in both eyes of a 60‐year‐old woman with progressive cone dysfunction but with normal rod function using for the perimetry a white tangential screen of 200 cd/m2 luminance and a 632 nm laser test light.

This study presents a preliminary comparison of six commercially-available automated threshold static parameters, consisting of three projection perimeters (Humphrey Field Analyzer, Squid, and Octopus 500) and three light-emitting diode (LED) perimeters (Dicon 2000, Fieldmaster 50, and Digilab 350).

The early Greeks and Romans knew that the visual fields had definite limits, but one finds no exact figures prior to those of Venturi, who gives the vertical extent as 112° and the lateral as 135° The part in the books on optics written by Ptolemy (150 A.

Despite important refinements that have improved quantitation and shortened test time, modern perimetry remains relatively insensitive and plagued by high test-retest variability. Some novel methods, though not yet fully vetted, offer the promise of improving sensitivity and reducing variability.

Principles and Practice of Perimetry.
Archives of Ophthalmology, 1931When the third edition of this well known book appeared several years ago, it was suggested to the author that its value would be greatly enhanced if he had used a little more care in accurately describing the conditions under which each field was taken and in faithfully recording the findings.

Like a painter, the practitioner of perimetry must learn his or her profession from experience. Just as a painting does not spring from the paint and brushes alone, the perimetrist does get his or her diagnosis from just a printout of the field test.
