Summary
The QuickSee autorefractor shows promise for measuring accommodative response in children without significant refractive errors. Its measurements closely align with the gold-standard Shin-Nippon device, suggesting potential for vision screening applications.
Area of Science:
- Ophthalmology
- Pediatric Optometry
- Vision Science
Background:
- Accurate measurement of accommodative response is crucial for understanding visual development and function in children.
- The QuickSee autorefractor is a novel device for assessing refractive status and accommodative function.
- Comparison with a gold-standard device is necessary to validate new autorefractor performance.
Purpose of the Study:
- To evaluate the QuickSee autorefractor's ability to measure accommodative response in children.
- To compare QuickSee measurements with those obtained from the Shin-Nippon autorefractor, a recognized gold-standard.
- To assess the inter-instrument agreement and reliability of the QuickSee for accommodative response assessment.
Main Methods:
- Recruited children aged 5-7 years without significant ametropia.
- Measured refractive status using QuickSee and Shin-Nippon autorefractors at distance and near demands (2, 3, and 4 D).
- Calculated accommodative response and analyzed inter-instrument agreement using Bland-Altman methods and repeated measures ANOVA.
Main Results:
- Forty-nine children participated, with a median spherical equivalent refraction of +0.38 D.
- Accommodative responses measured by QuickSee and Shin-Nippon showed close agreement across different accommodative demands.
- No significant proportional bias or significant differences in accommodative response measurements were found between the two devices (p ≥ 0.19).
Conclusions:
- The QuickSee autorefractor demonstrates good agreement with the Shin-Nippon device for measuring accommodative response in children with normal refractive status.
- The findings suggest the QuickSee holds potential for use in pediatric vision screening and assessment of accommodative function.
- Further research is warranted to explore its utility across a broader spectrum of refractive errors and in diverse clinical settings.
