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.

Purpose: This study measured corneal radius according to age and refractive error using Pentacam and analyzed its characteristics. Methods: For this study, we sampled 51 under-graduate students (29 males and 22 females, average age 22.50±3.31) and 39 elderly people (21 males and 18 females, average age 54.26±6.25) who gave their consent to the objective of this study and did not have any ocular diseases, ocular diseases history and refractive surgery. With the subjects, we performed objective and subjective refraction and measured the corneal radius using Pentacam. Results: The anterior corneal radius was shorter at an old age (p=0.005), and there was a significant correlation (r=0.259, p=0.000). The posterior corneal radius-was shorter at an old age (p=0.043), and there was a significant correlation (r=-0.282, p=0.000). According to refractive error, the anterior corneal radius was shorter in the myopes than in the emmetropes (p=0.016), but there was no correlation. The posterior corneal radius was shorter in the myopes than in the emmetropes (p=0.001), and there was a significant correlation (r=0.258, p=0.001). Conclusion: Age was correlated with the anterior and posterior corneal radius. Refractive error was correlated with the posterior corneal radius, but not with the anterior corneal radius.
