Conditions

Progressive myopia

Interventions

We aim to raise awareness and improve understanding of myopia among parents and children through myopia screenings and educational materials. No intervention

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Elementary school students (grades 2-5 at the time of registration) who have obtained parental consent for school health screenings

Exclusion criteria

Exclusion criteria: (1) Individuals from whom consent cannot be obtained (including those who indicate on the day of the examination that they do not wish to participate in the study) (2) Individuals deemed unsuitable for examination on the day of the examination (3) Cases where the examination data is insufficient or the image data is unclear, hindering data analysis

Design outcomes

Primary

Measure	Time frame
Comparison of Eye Examination Rates Between Groups Based on the Presence or Absence of Myopia Screenings and Educational Materials	—

Secondary

Measure	Time frame
Changes in Ophthalmic Parameters Correlation between refractive errors and corneal biomechanical factors (corneal thickness, corneal stiffness, etc.) Correlation between axial length and corneal biomechanical factors (corneal thickness, corneal stiffness, etc.) Correlation between the rate of myopia progression and corneal biomechanical factors (corneal thickness, corneal stiffness, etc.) Correlation between the rate of axial length elongation and corneal biomechanical factors (corneal thickness, corneal stiffness, etc.) Group-specific analysis of non-myopic (SE > -0.50 D), mild myopia (-0.50 D <= SE > -3.00 D), moderate myopia (-3.00 D <= SE > -5.00 D), and high myopia (<= -5.00) 7 Multivariate analysis to identify factors contributing to axial length growth Comparison with the rate of ophthalmology visits at Tomiya City Elementary School over the past 5 years *Evaluation and analysis will be performed using examination data from the 1st, 2nd, and 3rd years.	—
