Spot双目筛查仪对3～6岁儿童屈光不正筛查界值的研究OACSTPCD

Objective To compare the correlation between Spot binocular screening instrument and computer optom-etry in 3～6 years old children with cycloplegia,and to calculate the screening threshold of ametropia.Methods Cross-sec-tional study.Spot binocular screening and automatic computer optometry were performed on 1190 children in non-cycloplegic state.According to the screening criteria published by A APOS in 2021,the Spot ametropia screening threshold was calculated using ROC curve.Results There was a high positive correlation between Spot binocular screening instrument and automatic computer optometry instrument to measure the degree of spherical mirror,cylindrical mirror and equivalent spherical mirror.The ROC curve showed that the screening thresholds for astigmatism and farsightedness were-3.25D and+3.00D in the 3-year age group,and the screening thresholds for astigmatism,farsightedness and myopia in the 4～6 year age group were-1.75D,+1.00D and-2.00D,respectively.Conclusion There is good correlation and consistency between Spot binocular screening instrument and automatic computer optometry instrument,which can be used in the screening of risk factors of refractive amblyopia.
