•In order to be eligible to participate in this study, a patient must meet the following criteria:;Children cooperative for OCT examination.
•The refraction error must be within the range of -20 to +20 diopters due to limitations of the OCT device.;Untreated strabismic and anisometropic amblyopes:
•Within the age range of three to six years.
•With at least a two line visual acuity difference between the amblyopic and the fellow eye.
•Teated strabismic and anisometropic amblyopes:
•Within the age range of seven to twelve years.
•With equal (1.0 snellen) or nearly equal visual acuity, no more than one line difference.
•With at least a two line visual acuity difference between the amblyopic and the fellow eye before treatment.
•Treated as well as untreated anisometropic amblyopes need to have a difference in refraction error of at least 1 diopter spherical and/or 1 diopter astigmatic difference. ;Age matched controls:
•Are orthotropic or have a slight phoria on cover testing with quick recovery
•Have a similar refraction error, spherical and/or astigmatism of no more than 0,75 diopters.
