Abstract

Purpose: This study was designed to investigate the prevalence rate of refractive error with gender and age presenting visual acuity of primary student in Jeonnam. Methods: Subjective refraction, objective refraction and visual acuity test were examined on 735 primary school children who ages of 8~13 years lived in Jenman. Presenting visual acuity test was using Han's visual acuity chart and objective refraction was carried out using auto-refractometer. Results: The presenting visual acuity was 0.1 worse in the eye of 54(7.3%) students and 49(7.3%) of them wearing the glasses. The rate of the wearing glasses were 79.3% in 0.125~0.25 visual acuity, 64.2% in 0.3~0.5 visual acuity and 61.6% in 0.6~0.8 visual acuity. It was appeared that 269(36.6%) of them were emmetropia, 321(43.7%) of them were myopia and 56(7.6%) of them were hyperopia, and 89(12.1%) of them were astigmatism. The prevalence rate of myopia was the highest and followed by the prevalence rate of astigmatism. The low degree of myopia occupied the most and the medium degree of myopia showed the tendency of increase as the students get olds. The prevalence rate of the hyperopia showed the tendency of decrease as the students get olds. The prevalence rate of with the rule astigmatism were 50.6% students and against the rule astigmatism were 48.3% of students. Conclusions: The present study reveals the considerable prevalence rates, 466(63.4%) of included subjects, of refractive errors among primary students in Jeonnam province. The rate of the wearing glasses were 313(42.6%). The prevalence of myopia increases as the students get older. Therefore students of visual management is considered necessary through the visual acuity test and refractive examination.

목적: 본 연구는 전남지역 초등학생들의 성별과 연령, 나안시력에 따른 굴절이상 유병률에 관하여 알아보고자 한다. 방법: 전남지역 소재 8~13세, 735명의 초등학생을 대상으로 시력검사, 자각적 및 타각적 굴절검사를 실시하였다. 나안시력검사는 한천석식 시시력표를 이용하였으며, 타각적 굴절검사는 자동굴절계를 이용하였다. 결과: 전남지역 초등학생들 중 0.1이하의 나안시력을 보인 학생은 54명(7.3%)으로 나타났으며, 이중 49명(90.7%)이 안경을 착용하였다. 0.125~0.25의 나안시력을 보인 학생들의 안경착용률은 79.3%, 0.3~0.5의 나안시력을 보인 학생들은 64.2%, 0.6~0.8의 나안시력을 보인 학생들의 안경착용률은 61.6%를 보였다. 또한 정시 269명(36.6%), 근시 321명(43.7%), 원시 56명(7.6%), 난시 89명(12.1%)으로 굴절이상 유병률 중 근시 유병률이 가장 높게 나타났으며, 난시 유병률이 다음으로 높게 나타났다. 근시 중 약도근시의 유병률이 가장 높게 나타났으며, 약도 및 중도근시의 유병률은 연령이 증가할수록 증가하는 것으로 나타났다. 원시 유병률은 연령이 증가할수록 감소하는 것으로 나타났다. 난시 유병률에서 50.6%(45명)가 직난시, 48.3%(43명)가 도난시, 1%(1명)가 사난시를 보였다. 결론: 전남지역 초등학생들의 굴절이상 현황을 조사한 결과 466명(63.4%)의 학생들이 굴절이상을 가지고 있는 것으로 나타났고, 이중 안경교정 인원은 313명(42.6%)으로 나타났다. 또한 연령이 증가할수록 근시 유병률이 증가하는 것으로 나타나 정확한 시력검사와 굴절검사 후 적절한 교정을 통해 학생들의 지속적인 시력관리가 필요할 것으로 판단된다.
