title: JO and STATJO: programs for investigating the visual field with the Octopus automatic perimeter.
abstract: In evaluating the effectiveness of glaucoma therapy the visual field is the most important consideration. Comparison of visual fields is difficult, however, and only large changes are detectable with the methods of manual perimetry currently used. Two programs created for use with the Octopus automatic perimeter are described in this paper. One of the programs, called JO, is sensitive to small changes in threshold; the other, called STATJO, calculates means and converts the results to a form suitable for statistical evaluation.
