Table 4. Diagnostic ability of automated pupillometry parameters to discriminate compressive vs presumed microvascular ischemic third nerve palsy.

	Cut off value	AUC	Sensitivity (%)	Specificity (%)	Sensitivity at 95% specificity (%)	Specificity at 95% sensitivity (%)
Inter-eye difference
Minimum pupil diameter (mm)	0.45	0.840	83%	65%	17%	50%
CON (%)	-7.5%	0.844	89%	75%	17%	65%
ACV (mm/s)	-0.90	0.825	85%	68%	10%	60%
MCV (mm/s)	-1.12	0.811	88%	68%	17%	55%

AUC = Area under the curve; ACV = Average constriction velocity; CON = Pupillary constriction ratio (%); MCV = Mean constriction velocity; Parameters with an AUC of > 0.700 are presented.
