본 연구는 사시 약시 등의 이상이 없고 안경착용의 경험이 없으며 나안시력의 불편을 호소하는 초등학생 144명 288안을 대상으로 조절마비 전과 후의 굴절이상도의 변화를 측정하였다. 자동굴절검사를 이용한 조절마비 전과 후의 구면 대응치는 각각 -1.40D±1.04와 -0.77D±1.32로 -0.63D(t=-13.49, p
This study was carried out on 288 eyes of 144 primary school students who didn`t have strabismus or amblyopia, had never worn glasses, and complained about naked acuity. The change of refractive error for noncycloplegic and cycloplegic were measured using autorefractometer and retinoscope. The spherical equivalents of noncycloplegic and cycloplegic measured using autorefractometer were -1.40D±1.04 and -0.77D±1.32, respectively, showing that the cycloplegic refraction was significantly lower than manifest refraction by approximately -0.63D(t=-13.49, p<0.05).
