A clinical comparison of three computerized automatic perimeters in the detection of glaucoma defects
A. Heijl and S. M. Drance
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 Tubinger 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.
