[Relation of anisometropia and the extent of amblyopia].

The author deals with the problem of impaired binocular vision in children and the problem of the relationship of amblyopia and different refractions of the two eyes. Controversial views in the literature ar corrected by the author's evaluation of her own material, i.e. refraction of 939 children aged 3-6 years subjected to sciascopy during cyclopegia. The author concludes that in isometropia and low grade anisometropia various grades of amblyopia are found in monocular strabism. When the refractory difference is higher than 1 dioptre there is already a direct relationship between the level of anisometropia and the depth of amblyopia which is particularly marked when the difference is higher than 2 diopters. In amblyopia without strabism the relationship between amblyopia and anisometropia is unequivocal.
