Abstract

Objective To analyze the difference between the spherical equivalent (SE) before and after cycloplegia in preschool children and explore the effectiveness and feasibility of noncycloplegic autorefraction (NCAR) for large-scale myopia screening in children. Methods A cluster sampling method was used to select children aged 4 to 6 from 35 kindergartens in Changning district.The visual acuity (VA) and noncycloplegic autorefraction were measured in every child and cycloplegia autorefraction was measured in children with poor eyesight.Statistical analysis and linear regression analysis were conducted.The best positive cutoff points and their corresponding sensitivities and specificities for NCAR were also explored. Results SE was more positive after cycloplegia with statistical significance than that before cycloplegia, the linear correlation was proved between the SE before and after cycloplegia.When using NCAR to estimate myopia, the best positive cutoff point was SE less than -1.00D in children aged 4 years old and SE less than -0.75D in children aged 5~6 years old, respectively. Conclusion NCAR is an effective and feasible method for large-scale myopia screening in preschool children.
