목적: 본 연구는 유치원생들을 대상으로 안광학 성분 값들과 굴절이상도 간의 상관성을 알아보고자 하였다. 방법: 대상자는 안질환이 없는 유치원생 80안으로 하였다. 굴절검사, 각막굴절력, 각막곡률반경, 안축장, 전방깊이를 검사하고 분석 하였다. 안축장과 각막 굴절력사이에서 가장 높은 상관성을 보였다(r=-0.674, p=0.000). 키, 몸무게, 안축장(AL)/각막곡률반경(CR)비가 안축장과 양의 상관성을 보였다(r=0.351, r=0.408, r=0.488). 굴절이상과 각막굴절력은 안축장과 음의 상관성을 보였다(r=-0.302, r=?0.674). 전방깊이, 각막굴절력은 AL/CR 비와 양의 상관성을 보였다(r=0.422, r=0.280). 굴절이상, 각막곡률반경은 AL/CR 비와 음의 상관성을 보였다(r=-0.448, r=-0.396). 결론: 취학 전 어린들에 있어서 눈의 굴절이상을 진단하는데 AL/CR 비가 매우 중요한 지표임을 알 수 있었다.
Purpose: This study was to know the correlation among the dimensions of ocular components and refractive error on kindergarten children. Methods: The subjects were 80 preschool students who had no eye diseases. The refraction, corneal diopter, corneal radius, inter-pupillary distance, axial length, anterior chamber depth and dominant eye were measured and analysed. Results: It was shown that the highest correlation was between the axial length and the corneal diopter (r=-0.674, p=0.000). The ratio of height, weight and axial length (AL) to Corneal radius (CR) ratio were positively correlated with the axial length (r=0.351, r=0.408, r=0.488). The spherical equivalent of the refractive error and the corneal diopter were negatively correlated with the axial length (r=-0.302, r=-0.674). The anterior chamber depth and the corneal diopter were positively correlated with the AL/CR ratio (r=0.422, r=0.280). The spherical equivalent of the refractive error and the corneal radius were negatively correlated with the AL/CR ratio. Conclusions: It was shown that the AL/CR ratio was a very important indicator for diagnosing the refractive error of the preschoolers.
