Similarly, in patients with strabismic and combined mechanism amblyopia, 75% improved two or more lines of visual acuity with spectacle correction alone, with resolution of amblyopia occurring in more than a third of patients.11 Treating patients with spectacles first can help improve visual acuity, which can make penalization therapy easier for a patient.
