[Persistence of suppression after treatment for strabismic amblyopia: some remarks on two particular cases (authors'...

The dominant eye of these patients, successfully treated for strabismic amblyopia, has become myopic, while the previous amblyopic eye is now emmetropic: monocular visual acuity of the latter is good, but binocular vision, without correction, is equal to that of the non-corrected dominant myopic eye. During binocular vision the dominant eye maintains fixation even though its visual acuity is reduced with respect to the other eye: indeed the latter cannot be utilized to the best of its functional possibility, due to the presence of a suppressive central scotoma. A similar situation may be present during treatment with penalization of a strabismic amblyopia: it may not, therefore, be sufficient to lower the visual acuity of the dominant eye to a value less than that of the amblyopic eye (monocularly determined) to ensure utilization and exercise of this latter.
