Preoperative parameters	Preoperative TST		Preoperative TNO
	r	p	r	p
Minimum diameter of MH	0.41	0.006*	0.27	0.07
Base diameter of MH	0.40	0.005*	0.30	0.04*
Macular thickness	0.20	0.20	0.07	0.74
Defect length of ELM	0.39	0.007*	0.24	0.12
Defect length of EZ	0.16	0.33	0.05	0.89

*Significant correlation between parameters (Spearman rank correlation test).

TST = Titmus Stereo Test, TNO = TNO stereotest, ELM = external limiting membrane, EZ = ellipsoid zone, IZ = interdigitation zone.

OCT: optical coherence tomography, MH: macular hole.
