Abstract

Abstract

Objective To analyze cycloplegic refraction data of kindergarten and primary school students in Beijing in 2023, so as to provide scientific reference for selecting auxiliary methods for students myopia screening. Methods In the spring semester of 2023, a multi-stage cluster sampling method was used to select kindergartens and primary schools in one urban and one suburban district of Beijing. Two kindergartens and two primary schools were selected in the urban district, with 1 191 students undergoing cycloplegic refraction examination. And the suburban district included 66 kindergartens and 6 primary schools, with 3 555 students undergoing cycloplegic refraction examination. The examination items included pre- and post- cycloplegia optometry, axial length (AL), corneal curvature and height. Results In each academic stage, the area under the ROC curve (AUC) for the axial length/corneal radius of curvature (AL/CR) (Kindergarten: AUC=0.89, Lower primary school students: AUC=0.91, Upper primary school students: AUC=0.89) were higher than that of screening myopia, but the difference were not statistically significant (P>0.05). The AUC for axial length was the lowest (0.74, 0.82, 0.83) and lower than that for AL/CR with statistically significant difference (χ²=22.43, 59.04, 20.13, P < 0.05). After combining naked eye vision and AL/CR, kindergarten students showed an increased AUC from 0.83 (95%CI=0.78-0.88) to 0.93 (95%CI=0.89-0.97), and lower primary school students exhibited an increase from 0.89 (95%CI=0.86-0.91) to 0.96 (95%CI=0.95-0.97). In higher primary school students, AUC increased from 0.91 (95%CI=0.89-0.92) to 0.96 (95%CI=0.95-0.97). There was no overlap in the confidence intervals before and after combinations, and the differences were statistically significant (P < 0.05). Conclusion AL/CR plays a significant role in assisting with myopia screening among kindergarten and primary school students. Attention should be paid to the application of AL/CR in assisting myopia screening in kindergarten and primary school students.
