Trial summary

The global rise in myopia, particularly among children and adolescents in China, underscores the inadequacy of current prevention strategies, indicating that conventional screening and education alone are insufficient to curb the prevalence. Read more about this study

About this study

Official title: Impact of Feedback Based on the Myopia Prediction System on High Myopia Risk and Consultation Behavior in School-aged Children: a Cluster Randomized Controlled Trial

The global rise in myopia, particularly among children and adolescents in China, underscores the inadequacy of current prevention strategies, indicating that conventional screening and education alone are insufficient to curb the prevalence. Integrating personalized myopia prediction into routine care may enhance risk awareness, promote proactive prevention, and improve adherence to medical advice, ultimately reducing the future burden of high myopia.

A myopia prediction system based on artificial intelligence was previously developed, accurately predicting future high myopia risk using efficient, robust, and easily accessible predictive factors, including age, spherical equivalent, and the annual progression of spherical equivalent. This study aims to conduct a prospective, one-year, cluster randomized controlled clinical trial to investigate the effectiveness of this prediction system in preventing and controlling myopia in school-aged children.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of Individuals Predicted to Develop High Myopia at Age 18 by the Myopia Prediction System

    At the end of the one-year study, the Myopia Prediction System will be used to predict whether students will develop high myopia at age 18 in both the intervention and control groups. The Proportion of Individuals Predicted to Develop High Myopia at Age 18 by the Myopia Prediction System is calculated as the total number of students in each group predicted to develop high myopia by age 18, divided by the total number of students in the respective group.

    Measured: 1 year

  2. Cumulative Clinical Visit Rate for Myopia Prevention and Control

    The Cumulative Clinical Visit Rate Proportion of Clinical Visits for Myopia Prevention and Control is the proportion of students in the intervention or control group who visited a hospital or clinic for myopia-related care (e.g., refractive exams and treatment) at least once within three months of either intervention. It is calculated as the number of students in each group who attended a clinical visit within three months of at least one intervention, divided by the total number of students in the respective group.

    Measured: Within 3 months after each intervention

Secondary outcomes (4)
  1. Myopia Incidence Rate

    1-year myopia incidence rate = number of new myopia cases within one year / number of non-myopic cases at baseline * 100%

    Measured: 1 year

  2. Changes in Spherical Equivalent

    Change in spherical equivalent (non-cycloplegic autorefraction) will be calculated

    Measured: 1 year

  3. Screen Time

    Daily usage time of electronic devices (computer/smartphone/tablet computer) will be calculated

    Measured: 1 year

  4. Outdoor Activity Time

    Daily outdoor activity time will be calculated

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Feedback on Predicted High Myopia Risk at Age 18 Using the Myopia Prediction System and Feedback on Ophthalmic Examinations in people with Myopia and Randomized Controlled Trials, run by Zhongshan Ophthalmic Center, Sun Yat-sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?
