Duration of automated suprathreshold vs quantitative threshold field examination. Impact of age and ocular status
O. Kosoko, A. Sommer and C. Auer
We investigated the impact of age and ocular status on the duration of
automated threshold and suprathreshold testing of the visual field in a
study of 57 eyes with glaucomatous field loss, 58 eyes with ocular
hypertension, and 190 eyes of normal controls. It was faster to run a
three-zone threshold-related suprathreshold 120-point full-field screening
test on younger subjects and normal controls than on older subjects or
subjects with early glaucomatous field loss. In contrast, the time required
for full quantitative thresholding of 76 points within the central 30
degrees was unaffected by either age or ocular status. Normal individuals
required 40% more time to complete the quantitative threshold test than the
"full-field" screening test.
