Brief summary
Anisometropic amblyopia among children in school age may affects quality of life and educational progress of children.
Detailed description
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.
Interventions
DIAGNOSTIC_TESTAxial length measurement in millimeter (mm) by optical biometry device
Axial length measurement of the anisometropic eye and the fellow one in millimeter (mm) by optical biometry device.
DIAGNOSTIC_TESTAutorefractometer to measure the refractive error in both eyes.
Measurement of the refractive state of both eyes for each subject to asses the refractive error in diopter (D).
