Purpose: To evaluate the efficacy of anaglyphic three-dimensional movies to treat adults with anisometropic or strabismic amblyopia. Methods: This is an interventional case series. The seven cases were put on a trial frame containing subjective refraction, fogging plus lenses for the dominant eye, correcting prism, and anaglyphic red-cyan plastic spectacles. Patients participated in 20 sessions of 1.5 h of anaglyphic three-dimensional animated movie watching in the office. Significant visual acuity (VA) improvement was defined as improvement ≥0.2 in logMAR values. Change in octaves of stereopsis was defined as halving the arcsec or 0.3 change in log arcsec. Results: The average age was 26.9 ± 10.0 (16–42) years. The mean VA in amblyopic eye improved significantly from 0.42 ± 0.19 (0.15–0.7) logMAR to 0.25 ± 0.15 (0.1–0.5) logMAR after completion of sessions (P = 0.02), and four cases showed significant VA improvement. The mean stereoacuity improved significantly from 2.6 ± 0.3 (2.1–2.9) log arcsec to 2.1 ± 0.5 (1.7–2.9) log arcsec (P = 0.04). Four cases showed ≥2 octaves improvements in stereopsis. Conclusion: A simple and readily available method of amblyopia treatment can be effective in some adult cases.
