Example of poor agreement among members of the expert panel, and poor agreement with computer classification. Only two members of the expert panel initially and independently classified the defects in this visual field in exactly the same way, i.e., as a mild superior altitudinal, moderate inferior altitudinal, and severe central scotoma. Other classifications included a superior arcuate, inferior arcuate or paracentral scotoma. Only two members of the panel concurred with the computer classification (mild superior arcuate, moderate inferior altitudinal, and severe central scotoma). Two members believed that the inferior defect was an arcuate rather than altitudinal defect, one member believed that the field represented overall diffuse depression with a superior arcuate.
