Multicenter Evaluation of Near Vision and Outdoor Time in Kids Study

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:4 Years to 14 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:CHILD
Inclusion CriteriaExclusion Criteria
  1. 1. Aged 6 to below 14 years old
  2. 2. Spherical equivalent myopic refractive error greater than -0.50 D
  3. 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. 4. Good ocular and general health that would not preclude them from myopia control
  5. 5. Competent enough in English to fully understand the participant information and consent form
  6. 6. Willing to undergo treatment to slow myopia progression for one year
  1. 1. Strabismus at distance or near, or amblyopia
  2. 2. Systemic or ocular conditions that may affect contact lens use (e.g. severe allergy) or refractive development (e.g. ptosis)
  3. 3. Previous history of ocular surgery, trauma or chronic ocular disease that may affect their vision
  4. 4. Ocular or systemic medication use which may interfere or interact with myopia treatment or ocular development
  5. 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
