Purpose: To determine the relationship between stereoacuity (SA) and visual acuity (VA) in children with anisometropic amblyopia (AA). Methods: SA and VA were retrospectively analyzed before and after amblyopia treatment in 44 children with AA. Results: SA improved from 200 to 152 degrees of stereo arc (p< 0.005) and VA in amblyopic eyes improved from 0.3 ± 0.2 to 0.5 ± 0.3 (p<0.0000001) after amblyopia treatment. The improvement in SA was markedly less than expected given the improvement in VA. (p<0.005) using both internal and historic controls. Conclusions: The modest improvement in SA in the setting of a larger improvement in VA suggests the existence of "stereoscopic amblyopia" as an entity which is distinct from and less responsive to treatment than amblyopia of VA in orthotropic children with AA.
