Quantification of Metamorphopsia Using a Smartphone-Based Hyperacuity Test in Patients With Idiopathic Epiretinal Membranes: Prospective Observational Study

Correlation coefficients were calculated using the Pearson correlation (r). Classification of the magnitude of correlation by Wuensch and Evans [9] was used interpreting an r value below 0.20 as very weak, r values between 0.20 and 0.39 as week, r values between 0.40 and 0.59 as moderate, r values between 0.60 and 0.79 as strong, and r value above 0.80 as very strong correlation. A total of 30 patients were included into this study.
