Comparison of multifocal visual evoked potentials (mfVEP) amplitudes for amblyopic eyes and fellow eyes in the four quadrants of the visual field at the time of diagnosis and after occlusion treatment. The values of quadrant 1 between amblyopic eyes and fellow eyes only show statistically significant differences at the time of diagnosis (p = 0.005) but not after treatment (p = 0.888). *quadrant 1 at diagnosis in amblyopic eyes and fellow eyes: statistically significant difference, p = 0.005. Values are presented as mean ± SD (ms). P value derived from t-test for the comparison P: between amblyopic eyes and fellow eyes at the time of diagnosis *P:between amblyopic eyes and fellow eyes after treatment. **P: between at the time of diagnosis and after treatment in amblyopic eye ***P:between at the time of diagnosis and after treatment in fellow eye.
