Inclusion criteria: *diagnosed amblyopia caused by an anisometropia, strabismus or a combination of these two who received therapy with a visual acuity difference of two lines between the two eyes. *The patient has to be at least three years old and cooperative enough to sit through all examination, including the OCT examination. *Refractive error within the range of S+12.0 and S-12.0 due to the limitations of the OCT device. *A patient needs to have at least a 2 diopter spherical difference in refraction between both eyes and/or a 2 diopter astigmatic difference to be part of the anisometropic group. *Patients with any manifest ocular deviation or eccentric fixation will be included in the strabismic group. *To be part of the normal group, the patient needs to have a straight eye position, but phorias are allowed. The refraction needs to be similar in both eyes and should not be above S+5.0 or S-8.0, astigmatism should not exceed 2 diopters
