Visual acuity data from a child with anisometropic amblyopia before and after dichoptic training.(Birch et al., 2013) On the intitial visit at 4.4 years old, best corrected visual acuity for the amblyopic eye was 0.9 logMAR. Treatment with glasses, patching, atropine, and Bangerter filter resulted in improvement to 0.5–0.6 logMAR. Slight regression to 0.6–0.7 logMAR occurred, and visual acuity remained in this range for the next 3 years with continued spectacle wear. At 9.9 years, the child enrolled in the dichoptic treatment study and showed 0.2 logMAR improvement to visual acuity of 0.4 logMAR over the next 8 weeks. Three months after discontinuing dichoptic treatment, visual acuity for the amblyopic eye remained at 0.4 logMAR. Visual acuity of the fellow eye remained at 0.1 to 0.0 logMAR from age 7.4 years to 10.4 years.
