The peripheral visual field was measured with a single kinetic target and
the central 30 degrees with static stimuli in 600 eyes of 323 patients with
glaucoma and patients suspected of having glaucoma using an automated
perimeter (Fieldmaster 5000). The purpose of the study was to compare the
additional information gained by the peripheral field testing against the
time requirement for this extra procedure. An abnormal peripheral field
supported the diagnosis suggested by a central abnormality in 131 eyes
(21.8%), while a defect in the peripheral field provided the principal
diagnostic information, when the central field was normal or equivocal, in
25 cases (4.2%). Peripheral field measurements accounted for approximately
28% of the total testing time.
