Objectives

Narrative objectives1

This study focuses on myopia management in school health screenings, aiming to disseminate knowledge about myopia and raise awareness among parents and children,
while also conducting detailed evaluations of myopia using the latest ophthalmic diagnostic equipment. Through this, we aim to discover new biomarkers that can help predict the progression of myopia,with the goal of contributing to the development of effective future strategies for the diagnosis and treatment of myopia.

Assessment

Primary outcomes

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

Key secondary outcomes

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.
