 Evaluation of different algorithms for discriminating between controls and glaucomatous eyes using the rarebit perimetry testing

Algorithms	Sensitivity (%)	Specificity (%)	AROC (%)	Abnormals in OH group (% of eyes)
(1) MHR of <80%	92.3	95.1	0.94	44.2
(2) >15 areas with a non-hit rate of >10%	87.2	97.6	0.92	51.2
(3) ⩾2 areas with a non-hit rate of >50%	84.6	95.1	0.90	44.2
(4) at least 1 area with a non-hit rate of ⩾70%	82.1	100	0.91	51.2
(5) positivity at 1 of the previous algorithms	97.4	92.7	0.95	65.1
(6) positivity at 1 type of pattern distribution	84.6	90.2	0.89	51.2

AROC, area under the receiver operating characteristics curve; OH, ocular hypertension; MHR, mean hit rate.
