“…This area of our technical expertise was, therefore, fertile ground for development of automated techniques Fankhauser et al, 1972, Fankhauser, 1978Fankhauser and Bebie, 1979;Spahr et al, 1978;Haberlin et al, 1980;Bebie and Fankhauser, 1981;Gloor et al, 1981). First, however, it was necessary to define what it is that the perimetrist does and how to optimize the quality of the test including detection of lesions and measurement of visual deficits.…”

“…In short, this is still only partly a science and partly an art. To the extent it is a science, we need largely to thank Fankhauser et al Fankhauser et al, 1972;Fankhauser, 1978;Fankhauser and Bebie, 1979;Spahr et al, 1978;Haberlin et al, 1980;Bebie and Fankhauser, 1981;Gloor et al, 1981). They have asked the critical questions; such as, how many points need to be tested per field area for a given probability of detection of a lesion of a given size and depth etc.…”

“…The Octopus group has come up with some imaginative formats for display of data (Fankhauser and Bebie, 1979;Gloor et al, 1981;Haberlin et al, 1980;International Standard on Perimetry, 1929;Spahr et al, 1978) as has William Hart, Jr. at Washington University in St. Louis (1981 but there is certainly no simply agreed upon format for presentation of data between manufacturers.…”

“…Pressure for repeated evaluations at a single point in the field, the requirement for senstivie procedures for use in the relatively flat 'plateau' portion of the visual field, and the need for early and reliable detection of glaucomatous field defects led to the development of static perimetry, a form of quantitative, point-by-point perimetry. These techniques helped clarify the course of disease processes in a far superior manner (Aulhorn and Harms, 1972;Enoch, 1963;Gloor et al, 1981).…”

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. Automation and inclusion of computational procedures enhance the possibility of broad utilization for better screening and advanced testing. New test procedures make possible extremely fine localization of functions and allow superior definition of areas of involvement in pathology. New fundus perimeters make possible instantaneous fine correlations between functional changes and observed retinal anatomic lesions.

“…The visual field was analyzed with the G1 program of the Octopus system, performed with an Oc topus 2000 R (Interzeag, Switzerland). To reduce the effect of learning on the visual field results [8], patients and subjects underwent three different examinations with screening programs before the inclusion in the study.…”

This report presents the results of a study designed to verify the influence of lens opacities on the visual field indices. Four age-matched groups of subjects were considered: healthy volunteers, glaucomatous patients without lens opacities, cataractous patients without glaucoma and glaucomatous patients with lens opacities. The quantification of lens opacities was performed with the Lens Opacity Meter 701 instrument. The visual field indices were obtained automatically from the G1 program of the Octopus system. The statistical analysis of the results (coefficient of correlation) has shown that only the visual field indices that correspond to uniform and diffuse loss of light sensitivity were influenced by the presence of cataract. On the contrary, the visual field indices that indicate local irregularities of the threshold were not significantly influenced by the presence of lens opacities.
