From: Assessment of visual disability using visual evoked potentials
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).
