The correlation between actually measured visual acuity and calculated visual acuity. The visual acuity calculated by substituting the amplitude value of patients with optic neuritis into the function was 0.93 ± 0.30. The difference in the average between actually measured visual acuity and function value was 0.18 ± 0.4, indicating no statistically significant difference (t test, P = 0.07).
