Repeated low-intensity red light therapy for childhood myopia: a retrospective cohort study.

ABSTRACT:

Objectives

To evaluate the efficacy and safety of repeated low-intensity red light (RLRL) therapy in slowing myopia progression and improving accommodative function in children.

Methods

This retrospective cohort study reviewed electronic medical records of 202 myopic children aged 6-12 years treated at Ganzhou People's Hospital between October 2022 and October 2024. Participants were assigned to an RLRL group (n = 101; 650 nm, 1600 lx, 3 min, twice daily) or a control group (n = 101; single-vision spectacles only). Primary outcomes included axial length and spherical equivalent refraction. Secondary outcomes were uncorrected and best-corrected visual acuity, macular choroidal thickness, accommodative amplitude and facility, intraocular pressure (IOP), and corneal endothelial
