About this trial

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

Eligibility criteria

Qualifiers

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

Disqualifiers

Myopia greater than -6.00 diopters (D) spherical equivalent in either eye.

Previous intraocular or refractive surgery.

Previous dichoptic treatment > 2 weeks in duration

Ocular co-morbidity that may reduce visual acuity determined by an ocular examination performed within the past 7 months (Note: nystagmus per se does not exclude the participant if the above visual acuity criteria are met).
