Summary
The Plusoptix AO9 is a useful screening tool for refractive errors in children, but it shows differences compared to the TOPCON KR-8900 autorefractor, especially in high myopia or hypermetropia cases.
Area of Science:
- Ophthalmology
- Pediatric Optometry
- Refractive Error Assessment
Background:
- Accurate objective refraction is crucial for early detection and management of visual impairments in children.
- Screening tools aim to simplify and expedite the refractive assessment process.
Purpose of the Study:
- To compare objective refraction measurements obtained with the Plusoptix AO9 device against those from the TOPCON KR-8900 autorefractor.
- To evaluate the Plusoptix AO9's efficacy in identifying refractive errors in pediatric populations.
Main Methods:
- A prospective study involving 39 children (mean age 10.61 years) was conducted over 3 months.
- Objective refraction was measured using both Plusoptix AO9 and TOPCON KR-8900 autorefractor.
- Statistical analysis included F-TEST, correlation coefficients, and standard deviation of spherical equivalents.
Main Results:
- Significant differences in measurements were observed between the two devices in 20.51% of cases, particularly in children with strabismus.
- Plusoptix AO9 showed lower values in cases of small hypermetropia and higher differences in average hypermetropia.
- The Plusoptix AO9 was not feasible for assessing high hypermetropia or high myopia.
Conclusions:
- Plusoptix AO9 serves as a valuable screening tool for refractive errors in young children and those with collaboration difficulties.
- Discrepancies between Plusoptix AO9 and autorefractor necessitate further comprehensive eye examinations for accurate optical correction.
- The Plusoptix AO9 has limitations in detecting precise refractive values in cases of high hypermetropia or high myopia.
