목적 : 비우위안에 근시성 및 원시성부등시로 유도하였을 때 양안의 조절반응량을 측정하고자 하였다.
방법 : 교정시력이 logMAR 시력으로 0.0 이상이며, 안질환 및 전신질환이 없는 20명(24.05±1.73)의 피실험 자가 참여를 하였다. 비우세안에 +1.00, +2.00, -1.00, -2.00 D의 콘택트렌즈를 장입하여 부등시를 유도하였고, 조절자극량을 40, 20 cm로 변화시켜 개방형자동굴절검사기기를 활용해 조절반응량을 동적으로 측정하였다.
결과 : 조절자극 거리가 짧아질수록 조절반응량은 양안 모두에서 증가하였다(p<0.050). 굴절부등정도에 따라서 유의한 차이를 보였다(p<0.050). 40 cm에–는 -2.00 D의 원시성부등시로 유도 시 양안 모두 높은 조절반응을 보였 다(우세안 1.50±0.11 D, 비우세안 1.71±0.09 D). 부등시 종류에 따른 조절반응량의 비교 시 20 cm에서는 1.00, 2.00 D의 근시성 및 원시성부등시에서 우세안, 비우세안 모두에서 유의한 차이를 얻었으며(p<0.050), 40 cm에서는 1.00 D에서 우세안, 비우세안 모두 유의한 차이를 얻었다(p<0.050). 또한 양안의 조절반응량의 차이를 비교한 결 과, 근시도 및 원시도가 높아질수록 양안의 조절반응량의 차이 또한 높아짐을 확인하였고 그 차이는 40 cm와 20 cm사이에서 유의하였다(p<0.050).
결론 : 양안의 조절반응량은 부등시가 있는 경우에 차이가 발생한다. 종류에 상관없이 양안의 조절반응량의 차이 를 발생시키는 환경은 안정피로를 유발하므로 이 같은 상황을 방지하기 위해서 양안의 정밀한 조절검사가 필요할 뿐 만 아니라 정기적이며 지속적인 관리가 필요하다. 또한 양안의 차이를 고려한 안경처방 및 가입도 처방이 필요하다.

Purpose : The purpose of this study was to measure binocular accommodative response when hyperopic and myopic anisometropia were induced on non-dominatn eye.
Methods : Twenty participants (mean age: 24.05±1.73) who had corrected visual acuity more than 0.0 logMAR and no eye disease or systemic disease were recruited. The contact lenses with +1.00, +2.00, -1.00, -2.00 D were monocularly worn on non-dominant eye. The accommodative responses were measured by a binocular open-field autorefractometer when participant fixates target (accommodative stimulus) at 300, 40, and 20 cm.
Results : As the accommodative stimulus distance decreased, the amount of accommodative response increased in both eyes (p<0.050). There was significant difference of accommodative responses by different degree of anisometropia (p<0.050). When –2.00 D hyperopic anisometropia was induced, both eyes showed the highest accommodative responses at 40 cm (dominant eye 1.50±0.11 D, non dominant-eye 1.71±0.09 D). When comparing accommodative responses by the type of anisometropia, there was a significant differences in both the dominant and nondominant eyes at 20 cm when inducing 1.00 and 2.00 D in myopic and hyperopic anisometropia (p<0.050). At 40 cm, there was a significant differences in both the dominant and non-dominant eyes when inducing 1.00 in myopic and hyperopic anisometropia (p<0.050). In addition it showed that the higher the degree of myopia and hyperopia, the higher the difference in accommodative response on both eyes and the difference was significant between 40 and 20 cm (p<0.050).
Conclusion : There is a difference in the amount of accommodative response between dominant and non-dominant eye when anisometropia was induced. Regardless of the type, the environment that causes the difference in the amount of accommodative response between both eyes causes eye fatigue, so to prevent such a situation, not only the examination on accommodative response of both eyes, but also regular and continuous management is necessary. Also, a prescription for glasses and addition considering the difference between the two eyes is required.
