Synopsis

The prevalence of myopia among Hong Kong children increases rapidly in these few decades. However, the effectiveness of most available myopia control measures only ranges from 40% to 60%. A study on central retinal activity and myopia development showed that central inner retinal function was related to myopia progression in young children (Li et al., 2017). Another study on the defocus profile of near-work environment and myopia development revealed that near-work scene was associated with myopia progression in children (Choi et al., 2020). However, the associations between the intrinsic physiological factors and the extrinsic environmental factors contributing to myopia development and progression are still not clear. This study investigates the contribution and interactive effects of electro-retinal response, retinal structure, refractive parameters and scene of the daily environment on annual myopia progression in Hong Kong preschool children. The study may help to fill the gap of knowledge on how the intrinsic physiological factors and the extrinsic environmental factors contributing and interacting with myopia development, and thus having new insights on improving myopia control measures.
