Abstract:
As the prevalence of myopia has recently increased, there is growing interest in interventions to slow myopia progression. The choroid, the rearmost and largest part of the uveal layer, is a tissue rich in blood vessels located between the retina and the sclera. Recent advancements in diagnostic equipment have enabled direct imaging of the choroid, leading to increased research on its role in both normal and pathological conditions. Regarding myopia, it has been reported that; 1) the choroidal thickness decreases as the degree of myopia and axial length increase, 2) in the case of moderate to high concentrations of atropine or orthokeratology lenses, which are known to slow myopic progression, choroidal thickening is accompanied from the early stages of application, and 3) the mechanism by which choroidal thickening slows myopia progression is also being actively investigated. As a result, the choroid is being recognized as a therapeutic target for developing new interventions to slow myopia progression. Additionally, the increase in choroidal thickness has been reported as a predictive factor for the subsequent myopia progression, suggesting its potential role as a biomarker for assessing the likelihood of future myopia progression.
