Evaluating Near Vision and Outdoor Time in Children with Myopia

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to assess the relationship between outdoor time and near vision behavior in children diagnosed with myopia. By quantifying these factors, the study seeks to understand their impact on the efficacy of existing myopia control strategies. The findings will provide valuable insights for clinicians to better manage risk factors associated with myopia progression and enhance treatment responses. Participants will be monitored over a year to gather comprehensive data on their visual habits.

Why it matters

Who can join: the full rules

Inclusion Criteria:

1. Aged 6 to below 14 years old
2. Spherical equivalent myopic refractive error greater than -0.50 D
3. Best corrected logMAR visual acuity of 0.1 or better in each eye for 6- to 14-year-old children, and 0.2 logMAR or better than in each eye for 4 and 5-year-old children (adjusted for age-related expectations)
4. Good ocular and general health that would not preclude them from myopia control
5. Competent enough in English to fully understand the participant information and consent form
6. Willing to undergo treatment to slow myopia progression for one year

Exclusion Criteria:

1. Strabismus at distance or near, or amblyopia
2. Systemic or ocular conditions that may affect contact lens use (e.g. severe allergy) or refractive development (e.g. ptosis)
3. Previous history of ocular surgery, trauma or chronic ocular disease that may affect their vision
4. Ocular or systemic medication use which may interfere or interact with myopia treatment or ocular development
5. Child, parents or guardians not willing to comply with treatment and/or follow-up schedule and planning to migrate or move during the one-year study duration
