Purpose: This study was to analyze refractive error and corneal curvature radius in childhood myopia. Methods: The average age of 9.92 ± 1.08 years Children 50 people(24 males and 26 females) were evaluated for refractive error with an automatic refractometer, Pentacam was used to measure the corneal curvature radius. Results: The mean total spherical diopter was -2.43 ± 1.39D and astigmatism diopter was -0.75 ± 0.66D, horizontal radius of curvature was 7.88 ± 0.23mm, vertical radius of curvature was 7.67 ± 0.23mm, corneal astigmatism -1.18 ± 0.56D, diameter was 11.75 ± 0.47mm, eccentricity was 0.55 ± 0.10. There was no significant difference spherical diopter(t=-0.357, p=0.722), corneal astigmatism (t=1.410, p=0.162), eccentricity(t=0.627, p=0.532) in male and female, astigmatic diopter(t=2.097, p=0.039), horizontal radius of curvature(t=2.397, p=0.018), vertical radius of curvature(t=2.685, p=0.009), diameter(t=2.157, p=0.033) were significantly different. There was no significant difference spherical diopter(t=-0.952, p=0.343), astigmatism diopter(t=1.260, p=0.211), horizontal radius of curvature (t=-0.596, p=0.553) vertical radius of curvature(t=-0.495, p=0.621), corneal astigmatism(t=0.662, p=0.509), diameter (t=-0.411, p=0.682), eccentricity (t=0.080, p=0.937) between in male and female. Conclusions: Male and female were significant different astigmatism diopter, horizontal radius of curvature, vertical radius of curvature, diameter in childhood myopia. There was no significant difference between right eye and left eye.

목적: 각막 곡률반경을 Pentacam(Oculus inc., Germany)을 이용하여 측정하고 연령과 굴절이상도에 따라 비교·분석하였다. 방법: 본 연구의 취지에 동의하고 안질환이 없으며, 시력교정수술을 시행하지 않은 대학생 군 51명(남성 29명, 여성 22명, 평균나이 22.50±3.31세)과 장노년군 39명(남성 21명, 여성 18명, 평균나이 54.26±6.25세)을 선정하여 타각식 및 자각식 굴절검사를 실시하였고, Pentacam(Oculus inc., Germany)을 이용하여 각막 곡률반경을 측정하였다. 결과: 연령에 따른 각막 전면 곡률반경은 연령이 높을수록 짧았고(p=0.005), 유의한 상관관계가 있었다(r=-0.259, p=0.000). 각막 후면 곡률반경은 연령이 높을수록 짧았고(p=0.043), 유의한 상관관계가 있었다(r=-0.282, p=0.000). 굴절이상에 따른 각막 전면 곡률반경은 근시군이 정시군보다 짧았으나(p=0.016), 상관관계가 없었다. 각막 후면 곡률반경은 근시군이 정시군보다 짧았고(p=0.001), 유의한 상관관계가 있었다(r=-0.258, p=0.001). 결론: 연령과 각막 전·후면 곡률반경은 상관관계가 있었다. 굴절이상과 각막 후면 곡률반경은 상관관계가 있었고, 굴절이상과 각막 전면 곡률반경은 상관관계가 없었다.
