Example of poor agreement among members of the expert panel, and good agreement with computer classification. No member of the expert panel initially and independently classified the defects in this visual field in exactly the same way as any other member. Classifications included a mild inferior altitudinal with or without a moderate central scotoma and with or without a mild superior arcuate, or as a paracentral scotoma with or without a mild to moderate inferior arcuate scotoma. When asked if the computer classification was a valid clinical classification, all members of the expert panel concurred with the computerized classification (mild to moderate inferior arcuate and moderate central scotoma).
