초록

목적: 대전지역 대학신입생들의 굴절상태와 안광학상수를 측정하여 성인의 굴절이상 변화에 미치는 요인들을 분석하였다. 방법: 2008년 3월과 2009년 3월 2회에 걸쳐 76명(남 23명, 여 53명)을 대상으로 기본신체검사, 자동굴절검사, 각막곡률반경, 전방깊이, 안축장을 현성 및 조절마비 상태에서 측정하였다. 결과: 등가구면 굴절이상도는 -0.080±0.301D(p=0.001) 근시방향으로 진행하였고, 각막곡률반경은 -0.015±0.040 mm(p=0.000) 감소하였다. 전방깊이는 0.036±0.066 mm(p=0.000) 증가하였으며 안축장의 변화는 유의하지 않았고(p=0.274), AL/CR 비는 0.004±0.020(p=0.004) 증가하였다. 각막곡률반경 변화량과 굴절이상도 변화량은 양의 상관성이 있었고(r=0.578, p=0.000) 굴절이상도 변화량과 AL/CR 비의 변화는 음의 상관성이 있었다(r=-0.542, p=0.000). 굴절이상도 변화량과 안축장 변화량의 상관성은 유의하지 않았다(r=-0.074, p=0.367). 굴절이상도에 따른 변화에서 근시군의 등가구면 굴절이상도가 -0.134±0.316D 증가하여 원시나 정시보다 변화량이 가장 컸다. 근시군에서 굴절이상도 변화와 각막곡률반경 변화는 양의 상관성을(r=0.664, p=0.000), AL/CR 비 변화와는 음의 상관성을 보였다(r=-0.600, p=0.000). 각막곡률반경 변화와 AL/CR 비 변화는 음의 상관성을 보였다(r=-0.719, p=0.000). 정시군에서 굴절이상도 변화와 안광학성분 변화의 상관성은 유의하지 않았다. 원시군에서 굴절이상도 변화와 각막곡률반경 변화만 양의 상관성을 보였다(r=0.490, p=0.024). 결론: 이상으로부터 성인근시도의 증가는 각막곡률반경 변화 및 AL/CR비의 변화와 관련이 있으며, 성인근시의 원인은 안구성장보다 각막곡률반경의 변화가 더 큰 영향을 미치는 요소로 추정된다.

Purpose: This study analyzed the relationship between horizontal phoria and age. Method: The heterophoria of 166 children at 4 elementary school in Gyeongsangnamdo was measured with Howell card and investigated uncorrected visual acuity and refraction. Results: The means of age were 10.7±2.0years in all subjects, the means of uncorrected visual acuity were 0.60±0.39 in all subjects. And the means of best corrected visual acuity were 1.01±0.06 in all subjects, the means of spherical equivalent refraction were -1.06±1.53D. Among all of the subjects of the far phoria with age, the exophoria was 92 children(55.4%), the esophoria was 39 children(23.5%), the orthophoria was 35 children(21.1%)(f=32.259, p=0.000). In the 8 years, the exophoria was 14 children(41.2%), the esophoria was 11 children(32.4%), the orthophoria was 9 children(26.5%)(f=13.857, p=0.000). In the 9 years, the exophoria was 21 children(55.3%), the esophoria was 8 children(21.1%), the orthophoria was 9 children(23.7%)(f=16.955, p=0.000). In the 12 years, the exophoria was 36 children(62.1%), The esophoria was 13 children(22.4%), The orthophoria was 9 children(1.7%)(f=8.924 p=0.000). In the 13 years the exophoria was 22 children(61.1%), the esophoria was 7 children(19.4%), the orthophoria was 8 children(22.2%)(f=8.371, p=0.001). Among all of the subjects of the near phoria with age, the exophoria was 107 children(64.5%), the esophoria was 38 children(22.9%), the orthophoria was 21 children(12.7%)(f=33.138, p=0.000). The exophoria was 21 children(61.8%), the esophoria was 9 children (26.5%), the orthophoria was 4 children(11.76%) in the 8 years. The exophoria was 24 children(63.2%), the esophoria was 8 children(21.1%), the orthophoria was 6 children(15.8%) in the 9 years. The exophoria was 36 children(62.1%), The esophoria was 17 children(29.3%), The orthophoria was 5 children(8.6%) in the 12 years. The exophoria was 26 children(72.2%), the esophoria was 4 children(11.1%), the orthophoria was 6 children(16.7%) in the 13 years. In a study of 166 cases found a low, non-significant correlation between far phoria and increasing age. There is a significant correlation of near phoria between 8 years and 9 years(r = 0.710, p
