Summary

This is a prospective, school-based randomized controlled trial designed to evaluate auricular acupressure for myopia prevention in non-myopic primary school students with insufficient hyperopic reserve. Enrolled students in grades 1 to 4 will be randomly assigned to either an auricular acupressure intervention or usual daily activities without additional study-related myopia prevention intervention. Outcomes will include changes in axial length and cycloplegic spherical equivalent refraction, incident myopia, intervention adherence, and safety outcomes over 12 months.

Interventions

OTHER

Auricular Acupressure

Auricular acupressure will be performed using adhesive patches containing vaccaria seeds applied to selected auricular acupoints, including liver, spleen, heart, eye, kidney, Mu 1, Mu 2, and Shenmen. The intervention will be delivered once weekly by trained medical personnel according to a standardized protocol. Each application will remain in place for 5 days, followed by a 2-day rest period, with the treated ear alternated weekly. Participants will be instructed to press the patches three times daily, in the morning, at noon, and before bedtime, with 10 to 20 presses each time. If patches fall off, loosen, or cause local discomfort, the school health teacher or study personnel will be informed and appropriate management will be provided.

BEHAVIORAL

Eye Health Education

Standard school-based eye health education will include general guidance on healthy visual behaviors, near-work habits, reading posture, lighting conditions, eye exercises, and regular eye examinations.
