Comparison of short-term and long-term variability for standard automated perimetry (SAP) and spectral-domain optical coherence tomography (SD-OCT).

	SD of residuals Short-term	SD of residuals Long-term	P-value
SAP MD (dB)	0.61 ± 0.34	1.05 ± 0.70	<0.001^a
SD-OCT global RNFL thickness (μm)	0.81 ± 0.56	1.95 ± 1.86	<0.001^a

Values are presented as mean ± standard deviation

SD: Standard Deviation; MD: Mean Deviation; RNFL: Retinal Nerve Fiber Layer

Wilcoxon signed-rank test.
