Australia: A new study published in the Ophthalmology journal suggests that repeated low-level red-light (RLRL) therapy at 100% power significantly slowed the onset of myopia in myopic youngsters over the course of six months.

Despite the fact that open-label research has hampered earlier trials, repeated low-level red light therapy is developing as a treatment for controlling myopia. The goal of this study by Jing Dong and colleagues was to evaluate the effectiveness and safety of RLRL treatment in slowing the progression of myopia to a sham device that had just 10% of the original power.

112 Chinese children aged 7 to 12 who had myopia of at least -0.50 D, astigmatism of less than -1.50 D, and anisometropia of less than 1.50 D all took part in this double-blind, randomized, controlled clinical experiment. The RLRL group or the sham device control group, with a three-minute session length each session, twice daily, and a minimum four-hour gap between sessions, was randomly allocated to participants in a 1:1 ratio. Red light treatment was delivered at home using a desktop device. The fake gadget was identical to the real one, except only had 10% of its power. Axial length (AL) and cycloplegic refraction were assessed at baseline and after six months. Generalized estimating equations (GEE) were used to compare changes in cycloplegic spherical equivalence refraction (SER) and AL between the two groups.

The key findings of this study were:

1. 111 kids in all were included for the analysis. In the RLRL group, the mean SER change after 6 months was 0.060.30 D, while in the sham device control group, it was -0.110.33 D.

2. The mean increases in AL were 0.020.11 mm and 0.130.10 mm, respectively. Children in the RLRL group exhibited reduced axial elongation and myopia progression in the multivariate GEE models than children in the sham device control group.

In conclusion, the PI suggested that the RLRL therapy was well tolerated by the youngsters and it had no unfavorable side effects.
