Does repeated low-level red light therapy affect cone density in the macula of myopic children?

The increasing prevalence of myopia has become one of the major global public health issues.Current myopia control measures, such as orthokeratology lenses, defocus spectacles, soft defocus contact lenses, low-concentration atropine eye drops all have limitations.Repeated low-level red light (RLRL) therapy emerging in recent years has become one of the treatments for childhood myopia.Multiple clinical studies have shown that RLRL irradiation can inhibit the rapid progression of myopia in children and adolescents.Recently, a research report titled Cone Density Changes After Repeated Low– Level Red Light Treatment in Children With Myopia, which has sparked widespread discussion among parents of myopic children.The main purpose of this article is to conduct a detailed analysis of the research methods and results, and to explore whether the conclusion can be drawn that RLRL affects the density of macular cone cells in myopic children.
