A clinical comparison of three computerized automatic perimeters in the detection of glaucoma defects

The ability to detect glaucomatous field defects of three automatic computerized perimeters (COMPETER, OCTOPUS, and PERIMETRON) was compared in a clinical study of 74 patients. This study included patients with glaucoma, those with suspected glaucoma in whom the visual fields were completely normal, and normal subjects. The reference fields were obtained by careful static and kinetic manual perimetry on the Tübinger perimeter. All the automatic instruments gave similar high rates of detection of visual field loss and low false-positive test results. Quantity conventional manual perimetry is necessary to support automatic perimetric results, but automatic perimeters already can do a large proportion of routine perimetric screening.
