Table 4.
Calculation of the area under the curve for each parameter according to group constellation.
| Test result variable(s) | Glaucoma versus glaucoma suspect and normal | Glaucoma versus normal (glaucoma suspect removed) |
Glaucoma and glaucoma suspect versus normal |
|---|---|---|---|
| DDLS obtained by 3D optic disc photography | 0.931 | 0.974 | 0.915 |
| DDLS scored by the glaucoma specialist | 0.941 | 0.992 | 0.961 |
| Vertical C/D ratio | 0.842 | 0.896 | 0.873 |
| *Superior rim width | 0.828 | 0.852 | 0.751 |
| *Inferior rim width | 0.762 | 0.800 | 0.725 |
| Cup area | 0.746 | 0.868 | 0.856 |
| Disc area | 0.445 | 0.668 | 0.738 |
| *Rim area | 0.805 | 0.715 | 0.546 |
| C/D area ratio | 0.832 | 0.897 | 0.850 |
| *Rim disc area ratio | 0.833 | 0.898 | 0.851 |
| Cup volume | 0.691 | 0.893 | 0.887 |
| *Rim volume | 0.758 | 0.593 | 0.591 |
| Rim area (OCT) | 0.871 | 0.914 | 0.819 |
| Cup volume (OCT) | 0.680 | 0.879 | 0.876 |
| Average RNFL (OCT) | 0.832 | 0.874 | 0.780 |
DDLS: disc damage likelihood scale.
C/D: cup/disc.
OCT: optical coherence tomography.
*Parameters were negatively correlated with DDLS; thus, the area under the curve was obtained from 1 minus the original value.
