초록

목적: 본 연구는 근시안에서 현성굴절검사(manifest refraction: MR)와 조절마비굴절검사(cycloplegic refraction: CR)값을 비교하여 연령과 근시도에 따라 차이가 있는지 알아보고자 하였다. 방법: 근시성 굴절이상을 가진 229명 ($25.3{\pm}11.9$세)을 대상으로 조절마비제(cyclogyl 1%) 점안 전과 후에 자각적 굴절검사를 시행하였다. 결과: 조절마비제 점안 전 후 평균굴절력을 비교 조사하였더니, 근시 0.19 D, 난시 0.02 D 감소하였고 난시방향은 1.85도 차이를 보였다. 근시도의 변화는 30~40대에서 가장 높게 나타났으며, 229명(458안) 중 근시도수에서 0.50 diopter(D) 이상의 차이를 보이는 경우는 73안(16%)으로 근시도가 높은 군일수록 오차율이 높게 나타났다. 결론: 현성굴절검사와 조절마비굴절검사 값을 비교해 본 결과 연령에 따른 근시도의 변화는 유의하지 않았으나, 근시도가 높은 군일수록 오차율이 유의하게 높은 것으로 나타났다.

Purpose: The purpose of this study is to investigate difference between manifest refraction (MR) and cycloplegic refraction (CR) with age and myopic value. Methods: Manifest and cycloplegic refractions were carried out on the patients of 229 myopic patients ($25.3{\pm}11.9$ years old). Results: The average results from a pre- and a postcycloplegic refraction showed a reduction of 0.19 D in myopia, 0.02 D in astigmatism and $1.85^{\circ}$ in astigmatism direction. Change of myopic value was higher in 30~40 age. Total 73 eyes of 229 patients who showed 0.50 diopter (D) in spherical, and a high degree of myopia group showed a higher discrepancy rate. Conclusions: The results found in the comparison of the value of the manifest refraction and cycloplegic refractions showed changes of myopic value was not significant with age of patient, but the group of high degree of myopia showed higher discrepancy rate.
