Effects of Repeated Low-Level Red-Light Therapy on Subfoveal Choroidal Thickness in Children with Myopia: A Systematic Review and Meta-Analysis

Background/Objectives: Repeated low-level red-light (RLRL) therapy has recently emerged as a promising treatment for childhood myopia. Choroidal thickening has been proposed as a key biological mechanism underlying its therapeutic efficacy; however, evidence regarding its effects on subfoveal choroidal thickness (SFCT), particularly in children with premyopia, remains limited. This systematic review and meta-analysis aimed to comprehensively evaluate the effects of RLRL therapy on SFCT in pediatric patients with myopia and premyopia.
