초록

목적: 12~13세 초등학생을 대상으로 push-up 방법과 push-away 방법을 사용하여 측정된 조절력을 비교하고, 폭주 근점을 측정하여 조절 및 폭주 부족의 발생률을 알아보았다. 방법: 대상자는 안경교정시력이 1.0이상인 초등학교 학생 88명으로 평균연령은 $12.63{\pm}0.51$세(12~13세) 이었다. 조절력의 측정은 push-up 방법과 push-away 방법을 이용하였다. 폭주 근점은 분리점(break point)과 회복점(recovery point)을 측정하였다. 결과: 대상자의 단안 평균 조절력은 push-up 방법이 $11.52{\pm}2.50D$였고, push-away 방법은 $10.06{\pm}1.97D$로 측정되었다. 두 방법 간의 디옵터는 $1.46{\pm}1.58D$ 만큼 push-up 방법이 크게 측정되었다. 대상자의 평균 파괴점과 회복점은 각각 $8.66{\pm}1.99cm$과 $10.98{\pm}2.06cm$이었다. 조절 부족은 전체의 28.75%, 폭주 부족은 전체의 30.00%를 나타냈다. 나이에 따른 정상범위의 조절력을 보인 대상자와 폭주 근점의 측정값이 모두 정상 범위에 포함된 경우는 48.75%였다. 조절 부족과 폭주 부족이 함께 나타난 경우는 7.50% 였다. 결론: Push-up 방법과 push-away 방법으로 측정된 조절력은 0.6025의 높은 상관성을 보였다(P<0.05). 나이에 따른 정상적인 조절력을 가진 경우는 71.25%였고, 정상적인 폭주 근점을 보인 경우가 70.00%였다.

Purpose: We measured the amplitude of accommodation using the push-up and push-away tests and near point of convergence (NPC) and investigated the accommodative insufficiency (AI) and convergence insufficiency (CI) in elementary school children of 12~13 years old. Methods: 88 students who aged 12~13 $12.63{\pm}0.51$ years old with more than 1.0 spectacle best corrected visual acuity were examined using push-up and push-away tests. The break and recovery points of NPC also were measured. Results: Mean amplitudes of accommodations using push-up and push-away tests were $11.52{\pm}2.50D$ and $10.06{\pm}1.97D$, respectively in right eye (P<0.001). Mean break and recovery points in NPC were $8.66{\pm}1.99cm$ and $10.98{\pm}2.06cm$. AI and CI showed 28.75% and 30.00% each. 48.75% was within normal range in both amplitudes of accommodations according to their age expected and convergence. Students having both AI and CI were 7.50%. Conclusions: A high correlation between the push-up test and push-away test was found in elementary school children (r=0.6025; P<0.05). Students having normal amplitude of accommodation by their age expected and normal convergence were 71.25% and 70.00%, respectively.
