About this trial
The goal of this clinical trial is to compare the efficacy of myopia control lenses with different working principles in patients with intermittent exotropia aged 6 to 12 years. The main questions it aims to answer are:
Are there any differences in the clinical outcomes of DIMS and DOT glasses between children with intermittent exotropia and those with simple myopia (without intermittent exotropia)? Do DIMS and DOT glasses differ in their myopia control efficacy among children with intermittent exotropia? Does wearing DIMS or DOT glasses affect the binocular visual function of children with intermittent exotropia?
Eligibility criteria
Qualifiers
Participants aged 6 to 12 years (6 ≤ age ≤ 12 years). Written informed consent from legal guardians is mandatory.
Intermittent or constant exotropia at the distance of 6 meters, and intermittent exotropia or esophoria at the near distance of 33 centimeters;
Distance exodeviation ≥ 10 prism diopters (PD) measured via the prism and alternate cover test (PACT);
The difference between near and distance deviation ≤ 10 PD.
Disqualifiers
Participants who have worn myopia control glasses or received other myopia interventions, including low-concentration atropine and phototherapy instruments, within the past 6 months (excluding DIMS and DOT glasses).
Those with severe systemic diseases or cognitive impairment that hinders follow-up attendance and clinical examinations.
