Pearson Correlations of choroidal thickness measurements from any pair of three instruments.

Correlations of choroidal thickness between instruments

Instruments	Pearson Correlation	P
Cirrus vs Spectralis	0.976	< 0.0001
Cirrus vs RTVue	0.965	< 0.0001
Spectralis vs RTVue	0.964	< 0.0001

All systems are strongly correlated.
