PURPOSE: To compare the treatment efficacy between repeated low-level red light (RLRL) therapy and 0.01% atropine eye drops for myopia control.
METHODS: A single-masked, single-center, randomized controlled trial was conducted on children 7 to 15 years old with cycloplegic spherical equivalent refraction (SER) ≤ -1.00 diopter (D) and astigmatism ≤ 2.50 D. Participants were randomly assigned to the RLRL group or low-dose atropine (LDA, 0.01% atropine eye drops) group and were followed up at 1, 3, 6, and 12 months. RLRL treatment was provided by a desktop light therapy device that emits 650-nm red light. The primary outcome was the change in axial length (AL), and the secondary outcome was the change in SER.
RESULTS: Among 62 eligible children equally randomized to each group (31 in the RLRL group, 31 in the LDA group), 60 children were qualified for analysis. The mean 1-year change in AL was 0.08 mm (95% confidence interval [CI], 0.03-0.14) in the RLRL group and 0.33 mm (95% CI, 0.27-0.38) in the LDA group, with a mean difference (MD) of -0.24 mm (95% CI, -0.32 to -0.17; P < 0.001). The 1-year change in SER was -0.03 D (95% CI, -0.01 to -0.08) in the RLRL group and -0.60 D (95% CI, -0.7 to -0.48) in the LDA group (MD = 0.57 D; 95% CI, 0.40-0.73; P < 0.001). The progression of AL < 0.1 mm was 53.2% and 9.7% (P < 0.001) in the RLRL and LDA groups, respectively. For AL ≥ 0.36 mm, progression was 9.7% and 50.0% (P < 0.001) in the RLRL and LDA groups, respectively.
CONCLUSIONS: In this study, RLRL was more effective for controlling AL and myopia progression over 12 months of use compared with 0.01% atropine eye drops.
TRANSLATIONAL RELEVANCE: RLRL therapy significantly slows axial elongation and myopia progression compared with 0.01% atropine; thus, it is an effective alternative treatment for myopia control in children.
