Optometry and Vision Science, 1978
The history, theory, and practical application of automated perimetry are discussed. Optometrists are urged to consider increasing the efficiency of their examination procedures by using automated field testing--in particular, automated perimetry.

Seven subjects were studied to determine the reproducibility of color isopters utilizing a Tubingen perimeter with targets equated for radiant energy and separate for heterochromatic flicker luminance. Achromatic threshold recognition of targets for equal luminance gave smaller isopters with longer wavelengths (red).

American Journal of Ophthalmology, 1975
There is no single method of perimetric examination which is applicable to all types of visual field defects. Perimetry is a subjective psychophysical sensory examination. It is not an exact science unless one includes the objective measurement of visual evoked response in the optic cortex.

Retests in static perimetry [PDF]
Graefe's Archive for Clinical and Experimental Ophthalmology, 1988 A large pool of visual field data measured with the JO program on the Octopus automated perimeter was used to compare the outcomes of simulated selective retests to those of global retests. Compared to global retesting, with selective retesting an increase in the mean sensitivity and a decrease in the number of pathological test locations were found on

To the Editor. —In studying the article by Trobe and Glaser (Archives96:1210-1216, 1978), I was struck by two facets that deserve mention. First, the authors refer to a color saturation difference at the vertical meridian as a hemiachromatopsia. Theoretically, the authors are actually defining a hemidyschromatopsia since there is a dysfunction of ...

Evaluation of oculokinetic perimetry
Australian and New Zealand Journal of Ophthalmology, 1999Background and Method: Oculokinetic perimetry (OKP) was performed on 98 patients (187 eyes) using the Damato 26‐point glaucoma screening chart. Results were compared with those obtained from a 24‐2 full threshold test on a Humphrey Field Analyser (HFA).

Ophthalmology Clinics of North America, 2003
As distinguished from measuring the ability to see at the location where the eye's gaze is fixated, perimetry consists of determining the visual capabilities throughout the field of vision. Traditionally the ability to see a white object or a projected spot of white light is determined and quantified under standard conditions.

Documenta Ophthalmologica, 1983
Perimetry is clearly in an explosive stage of development. Here, an attempt is made to bring together major developments and put them into an orderly perspective. The projection-bowl-perimeters of Bern and Tübingen set the stage. Standardization provides the base for future development and data exchange.

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.

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.
