Correlation of sVEP acuities and psychophysical acuities with letter acuity. Colors represent the groups: blue, normal vision controls; red, anisometropic amblyopes; green, strabismic amblyopes. Open symbols represent the dominant eye. Filled symbols present the nondominant eye. Solid lines: 1:1 ratio. (A) SVEP grating acuity and (B) Vernier acuity were compared with letter acuity. (C) Psychophysical grating acuity and (D) Vernier acuity were compared with letter acuity. Vernier acuity was measured with Vernier displacement, on/off, at 3.75 Hz. Grating acuity was measured with on/off modulation at 3.75 Hz.
