Correlations among HRT parameters

		CA	C/D	RA	HVC	CV	RV	MnCD	MxCD	CSM	MnRNFLT	RCSA
Values are shown as the Pearson correlation coefficient for 18 animals. p<0.05, *p<0.01 (Pearson’s correlation test).
DA, disc area; CA, cup area; C/D, cup/disc area ratio; RA, rim area; HVC, height variation contour; CV, cup volume; RV, rim volume; MnCD, mean cup depth; MxCD, maximum cup depth; CSM, cup shape measure; MnRNFLT, mean RNFL thickness; RCSA, RNFL cross section area; RNFL, retinal nerve fibre layer.
