Example of good agreement among members of the expert panel, and moderate agreement with computer classification. Five members of the expert panel classified the defects in this visual field as a moderate superior arcuate and a moderate inferior arcuate, while the other member classified the defects as a moderate nasal step and inferior arcuate. None agreed with the computer classification, moderate superior arcuate and severe inferior nasal step. Five members of the panel concurred with the computerized defect pattern classification, although only three agreed with the severity classification. Dissenting members thought that defects were either both severe or both moderate. The remaining member thought that the defects were best described as moderate superior and inferior arcuate scotomas.
