Correlation coefficients, coefficients of determination, and probability values determined for correlations between various visual functions and quality of life scores

VQOL	Correlation coefficient (r)	Coefficient of determination (r2)	Probability (P)
HCVA (worse eye)	0.21	0.044	0.015
HCVA (better eye)	0.28	0.078	0.0012
HCVA (binocular)	0.28	0.080	0.0011
LCVA (binocular)	0.24	0.056	0.0065
CS (binocular)	0.24	0.059	0.005

HCVA = high contrast visual acuity; LCVA = low contrast visual acuity; CS = contrast sensitivity; VQOL = Vision Quality Of Life.
