Trial summary

Currently, optical and pharmacological interventions have been developed to prevent the progression of childhood myopia. However, no myopia control strategy has been shown to have complete efficacy in controlling myopia progression in children. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 4 to 14 years
  • All sexes
  • No healthy volunteers
  • Child

Study population: Myopic children will be recruited from the university based myopia control clinic. Some clinical sites have collaborated with community optometry practices so support recruitment.

Who may be able to join

  • Aged 6 to below 14 years old
  • Spherical equivalent myopic refractive error greater than -0.50 D
  • 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)
  • Good ocular and general health that would not preclude them from myopia control
  • Competent enough in English to fully understand the participant information and consent form
  • Willing to undergo treatment to slow myopia progression for one year

Who cannot join

  • Strabismus at distance or near, or amblyopia
  • Systemic or ocular conditions that may affect contact lens use (e.g. severe allergy) or refractive development (e.g. ptosis)
  • Previous history of ocular surgery, trauma or chronic ocular disease that may affect their vision
  • Ocular or systemic medication use which may interfere or interact with myopia treatment or ocular development
  • 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

About this study

Official title: Multicenter Study of Near Vision Behavior and Outdoor Time in Children Undergoing Myopia Control

Currently, optical and pharmacological interventions have been developed to prevent the progression of childhood myopia. However, no myopia control strategy has been shown to have complete efficacy in controlling myopia progression in children. One possible reason is that risk factors contributing to the development of myopia were not controlled in previous clinical studies including time outdoors and near vision behaviour. This study aims to quantify time spent outdoors and near vision behavior in myopic children and its impact on myopia control efficacy. The outcomes of this study will guide clinicians on risk management and improve responses to existing treatments for progressive myopia.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ViviorDevice

    The Vivior is a wearable clip-on sensor that objectively quantifies near viewing distance and duration, and ambient illumination. The Vivior will be attached to the spectacles frame of children undergoing myopia control treatment.

What is being measured

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

  1. Near viewing duration

    Duration during near tasks

    Measured: 12 months

  2. Near viewing distance

    Distance during near tasks

    Measured: 12 months

  3. Outdoor time

    Ambient illumination to determine time spent outdoors

    Measured: 12 months

Secondary outcomes (3)
  1. Objective cycloplegic central refraction

    Change in objective refraction to measure myopia progression

    Measured: 12 months

  2. Axial length

    Change in axial length to measure myopia progression

    Measured: 12 months

  3. Subjective cycloplegic central refraction

    Change in subjective refraction to measure myopia progression

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Myopia, run by The University of New South Wales at 5 sites in 2 countries.

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

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 12 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States, Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Pauline Kang, PhD (612 9065 6112, p.kang@unsw.edu.au), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Near viewing duration (time frame: 12 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Dec 2024.
