Example of poor agreement among members of the expert panel, but agreement with computer classification. Three members of the expert panel initially and independently classified the defects in this visual field as a moderate superior arcuate and severe inferior altitudinal scotoma. One member classified the superior defect as an arcuate-altitudinal, while two other members thought this visual field also had a moderate central scotoma in agreement with the computerized classification. When asked if the computer classification was a valid clinical classification, all members of the expert panel concurred with the computerized classification (moderate superior arcuate, severe inferior altitudinal and moderate central scotoma).
