Abstract

Purpose: This study is to predict refractive errors according to uncorrected visual acuity using uncorrected visual acuity of the first glasses wearers. Methods: For 886 children who visited an ophthalmic clinic, subjective refraction was carried out with maintain refraction (MR) and cycloplegic refraction (CR), and objective refraction was carried out using auto-refractometer. Uncorrected visual acuity and corrected visual acuity were tested using on a trial lens and a Han's visual acuity chart. Results: In correlation between with the uncorrected visual acuity and refractive the myopia was the highest (r=0.774) and followed by hyperopia (r=0.670), simple astigmatism (r=0.623), simple with-the-rule astigmatism (r=0.604)and simple against-the-rule astigmatism (r=0.508). Conclusions: There were differences in the predictions between uncorrected visual acuity and refractive error according to the types of refractive error and astigmatism.

목적: 본 연구에서는 최초 안경착용자의 나안시력을 이용하여 그에 따른 굴절이상량을 예측하고자 하였다. 방법: 안과병원을 내원한 886명을 대상으로 자각굴절검사는 현성굴절검사(M.R)와 조절마비굴절검사(C.R)를 같이 실시하였으며, 타각적굴절검사는 자동굴절계를 이용하였다. 나안시력 검사와 교정시력은 시험렌즈와 한천석시력표를 이용하여 실시하였다. 결과: 나안시력과 굴절이상의 상관성은 근시안이 r=0.774로 가장 높게 나타났으며 원시안 r=0.670, 단성직난시 r=0.623, 단성난시 r=0.604, 단성도난시 r=0.508 순서로 나타났다. 결론: 굴절이상과 난시 종류에 따라 나안시력과 굴절이상의 예측에 차이가 있었다.
