Automation of perimetry is quite feasible in normal subjects (3.6 % failures). It is equally feasible in patients with visual field defects not over 60 years of age (0 % failures). Automated examination ends in failure in 30 % of the patients in the older age groups seen in our clinic.

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.

A Comparison of Peritest Automated Perimetry and Goldmann Perimetry
Archives of Ophthalmology, 1985Both Peritest perimetry and Goldmann visual field testing were performed on three groups of eyes. Eighty-one eyes had glaucoma with elevated intraocular pressures and abnormal visual fields determined by Goldmann perimetry. There were 47 eyes with suspected glaucoma, based on elevated IOPs and normal Goldmann visual fields.

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).

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

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.

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 ...

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.

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).

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.
