Anisometropic amblyopia among children in school age may affects quality of life and educational progress of children.
Correction of anisometropic amblyopia depends on type of refractive error and axial length of the eye.
In this study, we will asses the types of anisometropia found in children at school age and investigate possible ways for correction of this type of amblyopia.
