Abstract
AIM:To evaluate the value of the ratio of axial length to corneal radius of curvature(AL/CR)in the diagnosis of myopia in children and adolescents.
METHODS:The refraction and ocular biometric parameters of 2 182 cases of children and adolescents(4 364 eyes)who initially visited the optometry clinic of the Second People's Hospital of Beihai from January 2022 to December 2023 were collected and analyzed.
RESULTS:The receiver operating characteristic curve(ROC curve)showed that AL/CR had a higher area under the curve(AUC=0.925,95％CI:0.917-0.933)in diagnosing myopia.When AL/CR was 3.053,the Youden index was the largest.As the threshold of AL/CR decreased,the sensitivity of myopia diagnosis increased,while the specificity decreased.Compared with screening myopia,the sensitivity of AL/CR=3.053 in diagnosing myopia was low,but the specificity was high,especially in the cases of hyperopia and pre-myopia.
CONCLUSION:The accuracy of AL/CR in diagnosing myopia is superior to that of axial length and average corneal curvature,with higher specificity.As the threshold of AL/CR decreases,the sensitivity of diagnosing myopia increases,but the specificity decreases.In cases of hyperopia and pre-myopia,the specificity of AL/CR in diagnosing myopia is higher than that of screening myopia.关键词
