Optical Coherence Tomography May Help Distinguish Glaucoma from Suprasellar Tumor-Associated Optic Disc

Table 2

Multivariate analysis of factors predicting glaucoma (as opposed to suprasellar tumor). The area under the curve (AUC) and odds ratio of each factor are presented.

		AUC	Odds ratio	95% CI
				Lower	Upper
Total RNFL thickness (per μm)	0.008	0.67	1.116	1.002	1.243
Disc area (per 100 μm^2)	0.002	0.79	2.402	1.027	5.619
Cup volume (per 100 μm^3)	0.194	0.82	4.146	0.354	48.595
Cup/disc ratio (per 0.01)	0.071	0.65	0.765	0.551	1.063
Rim area (per 100 μm^2)	0.011	0.56	0.272	0.070	1.058

RNFL: retinal nerve fiber layer; AUC: area under the curve in individual ROC analyses.
