Abstract
We examined 27 glaucomatous eyes and 154 normal eyes with automated threshold perimetry.
Previously suggested algorithms for detecting mild to moderate glaucomatous visual
field loss, primarily by comparing the sensitivity of corresponding clusters of points
above and below the horizontal meridian, yielded results remarkably consistent with
those of our earlier series: 93% (25 of 27) of abnormal and 88% (135 of 154) of normal
eyes were correctly identified. Excluding unreliable examinations increased specificity
from 88% to 93%. Test duration was similar to results with the Field Analyzer's older,
purportedly slower operating system.
