Eye Diseases Clinical Trial
Official title:
Repeated Low-level Red-light Therapy in High Myopia Children and Teenagers: a Prospective Single-arm Study
The purpose of this clinical trial is to investigate the incidence and magnitude of axial length shortening after repeated low-level red-light therapy in high myopia children and teenagers.
High myopia has become a major public concern globally, which is characterized by excessive axial elongation of the eyeball. Axial elongation is accompanied by mechanical stretching and thinning of the choroid and sclera, causing vision-threatening complications. Repeated low-level red-light (RLRL) therapy is an emerging effective and safe therapy for myopia control. Previous clinical trials in China have observed clinically significant axial shortening after RLRL treatment. The purpose of this study is to investigate and identify possible mechanism for axial length (AL) shortening after 12-month RLRL therapy in highly myopic children and teenagers aged 8-18 years. In addition to single vision spectacles, subjects will receive RLRL treatment at home under supervision of the parents/guardians according to a standard protocol. Axial length, visual acuity, cycloplegic spherical equivalent refraction, slit lamp, fundus camera and optical coherence tomography/angiography will be measured at 1-, 3-, 6- and 12-month follow-up visits. ;
