Abstract

Background: The effectiveness of amblyopia therapy can be limited by poor adherence. Dichoptic therapies are a new approach, but recent trials have demonstrated difficulty maintaining high adherence over extended periods of at-home treatment. We evaluated the efficacy and adherence of Luminopia One—a dichoptic treatment that applies therapeutic modifications to streaming content chosen by the patient. Methods: This single-arm, multicenter prospective pilot study enrolled children aged 4-12 with anisometropic, strabismic, or mixed amblyopia at 10 pediatric ophthalmic and optometric practices across the United States. The therapeutic was prescribed for 1 hour/day, 6 days/week for 12 weeks of at-home use. The primary endpoint was best-corrected visual acuity (BCVA) at the 12-week follow-up visit. Results: In total, 90 participants (mean age, 6.7 ± 2.0 years) were enrolled, and 73/90 participants (81%) had prior treatment beyond refractive correction. For those who completed the 12-week visit, mean amblyopic eye BCVA improved from 0.50 logMAR to 0.35 logMAR (1.5 logMAR lines; 95% CI, 1.2-1.8 lines; P < 0.0001). Mean stereoacuity improved by 0.28 log arcsec (95% CI, 0.14-0.42 log arcsec; P < 0.0001). Median adherence was 86% (interquartile range, 70%-97%). Conclusions: In our study cohort, adherence over the 12-week study period was high, and participants demonstrated clinically and statistically significant improvements in visual acuity and stereoacuity.
