전북 지역 고등학생 비정시에 관한 연구

A Study on the Ametropia of High School Students in Jeonbuk Province

본 연구는 전북지역 고등학생 비정시 182명 364안을 대상으로 타각적, 자각적 시력 검사를 시행하여 비정시의 정도 및 굴절 이상상태를 연구하였다. 1. 눈의 형태는 근시는 85.7%, 원시는 7.6%, 그리고 정시는 6.6%로 나타났다. 2. 굴절이상안은 단순근시 29.6%, 근시성 복난시 56.3%, 근시성단난시 7.2%, 원시성단난시 1.8%, 원시성 복난시 1.2%, 혼합난시 1.8%, 단순원시 1.8% 이었다. 3. 난시의 축은 직난시 78.7%, 도난시 13.9%, 사난시 7.4%이었다. 4. 난시의 굴절력은 0.50dptr에서 1.0dptr가 64.6%. 1.0dptr 에서 2.0dptr가 29.1%, 2.0dptr 이상이 6%이었다. 5. 근시성 굴절이상안의 등가구면굴절력은 -0.50dptr 에서 -2.0dptr 이하 40.1%, -2.0dptr에서 -6.00dptr 이하 56.6%, -6.00 이상이 36.8% 이였다. 6. 원시성 굴절이상안의 등가구면굴절력은 2.00dptr 이하 50%, 2.00dptr 이상이 50%이었다.

To investigate the ametropia and refractive error of 364 ametropic eyes en the 182 high school students in Jeonbuk provicne, the visual acuity test was performed by the object and subject method. The results were as follows. 1. The eye types were 85.7% positive for myopia, 6.6% for emmetropia and 7.6% hyperopia, respectively. 2. The abnormal refraction eyes were 30.8% positive for simple myopia, 58.5% for myopia compound astigmatism, 7.5% for myopia simple astigmatism, and 1.8% for simple hyperopia, 1.3% for hyperopia compound astigmatism, 1.9% for hyperopia simple astigmatism, respectively. 3. The axes of astigmatism were 78.7% for astigmatism with-the-rule, 13.9% for astigmatism against-the-rule, 7.4% for astigmatism oblique, respectively. 4. As for the astigmatic power, the 0.50 < cylinder < 1.00dptr was 60.0%, the 1.00 < cylinder < 2.00dptr was 29.2%, and anything over the 2.00cylinder dptr was 10.8%. 5. As for the equivalent spheric power of myopic abnormal refraction eyes, the -0.50 < spheric equivalent < -2.00 diopter was 64.6%, the -2.00 < spheric equivalent < -6.00 dptr was 29.1% and anything over the -6.00 dptr was 6%. 6. The equivalent spheric power of hyperopic abnormal refraction eyes was 50% anything under 2.00diopter and 50% for anything over the 2.00diopter.
