The goal of this study is to compare the change in amblyopic eye acuity between treatment periods in children with amblyopia, aged 5-17 years. The main question it aims to answer is: Is a 16-week course of amblyopia treatment using Vivid Vision Therapeutic (Dichoptic) Virtual Reality Games for approx. 25 min/day, 6 days/week more effective for improvement in amblyopic-eye VA, binocularity (stereoacuity, suppression, alignment), contrast sensitivity, attention, oculomotor function, visual-motor integration, and quality of life than 16 weeks of continued glasses alone? Participants will each serve as their own control and complete: Treatment period 1: Continued optical correction (glasses) alone for 16 weeks; Treatment period 2: Vivid Vision Therapeutic (Dichoptic) Virtual Reality Games for 16 weeks (approx. 25min/day, 6 days/week) plus continued optical correction
Inclusion Criteria: Patients ages 5 to 17 years of age * Moderate to severe unilateral amblyopia (logMAR best corrected visual acuity 0.3 to 1.3) associated with anisometropia and/or strabismus of ≤5pd * Age normal VA in the nonamblyopic eye * Spectacle correction (if required) worn for at least 16 weeks, or until stability of VA is demonstrated (\<0.1 logMAR change by the same testing method measured on 2 exams at least 8 weeks apart) * Interocular difference of ≥ 3 lines * No amblyopia treatment in the past 2 weeks * An interpupillary distance of 52-72 mm (inclusive) Exclusion Criteria:…
