Visual acuity is decreased in one or both eyes in Amblyopia. We studied BOLD responses on visual stimulation using black and white checkerboard flickering at different frequencies (4, 8 and12 Hz) in unilateral Anisometropic Amblyopes and observed the maximum visual cortex BOLD activation observed at 8 Hz correlates.
