What this Trial Is About

Researchers are evaluating the short-term effects of different types of red light therapies on the choroidal and retinal structures in adults with myopia. The main goal is to find out which areas or cells of the retina are most affected by repeated low-level red-light (RLRL) therapy, especially regarding choroidal thickening. The study also aims to check the safety of these red light therapies in adults aged 18 to 40 years with myopia. Participants will be randomly assigned to one of three groups receiving RLRL therapy using the Eyerising Myopia Management Device. The groups differ by the size and shape of red light spots used on the retina but have the same light power. Each participant will receive daily treatments for 14 days, with two 3-minute sessions each day separated by at least 4 hours. The therapy device settings vary by group to test different light spot patterns while ensuring participant safety. Before starting treatment, baseline eye exams and measurements will be done, including visual acuity, eye length, retinal imaging, and electrical activity tests. During the 14-day treatment, participants will have daily eye assessments to monitor changes. The study will measure changes in choroidal thickness, retinal electrical activity, axial length, and vision clarity, along with detailed imaging reports. This helps researchers understand how red light therapy affects myopia and identifies areas of the retina that respond most to the treatment.
