What this Trial Is About
Researchers are conducting a multi-center observational study to establish normal ranges for axial length in Chinese children and adolescents aged 3 to 18 years. The study aims to better understand eye development and myopia progression in this population by gathering detailed ocular measurements. Participants include both children with myopia and those without. All children will undergo eye exams using cycloplegia to measure their ocular parameters. The study will follow these children for three years with annual visits to track changes in axial length and eye growth. During the study, children will attend yearly visits where eye assessments will be performed to measure axial length and its elongation over time. Researchers will collect data on eye health and development to inform future care and prevention strategies. Participation involves minimal risk and will last for three years.
