refractive amblyopia --> anisometropic amblyopia A suppression
of central vision due to an unequal refractive error
(anisometropia) of at least two diopters. This induces a
sufficient difference in image size (aniseikonia) that the two
images cannot be fused. In order to avoid confusion, the
blurrier image is suppressed. Synonym: refractive amblyopia.
