초록

목적: 양안으로 사물을 주시할 때 우세안을 주로 사용한다. 이러한 이유로 안경과 콘택트렌즈 처방 시 우세안의 중요성이 크다. 이를 위해 본 연구는 연령대별로 구분하여 양안에 있어서 굴절력의 변화에 따른 우세안과 비우세안의 시력 차이가 있는지 알아보았다. 방법: 안질환이 없는 186명을 대상으로 Hole-in-the-card test법을 통한 우세안을 검사하였다. 검사의 일관성을 위해 동일인이 측정하였으며, 검사의 신뢰성을 높이기 위해 3회 반복 실시하였다. Spss통계를 통해 굴절력에 따른 우세안과 비우세안의 상관관계를 알아보았다. 결과: 대상자 186명 중 우안 우세안은 135명, 좌안 우세안은 51명이었다. 굴절이상 환경에 노출되기 시작하는 10세 이전(평균 $8.8{\pm}1.18$세)과 본격적으로 굴절이상이 발생하는 10세에서 20세 사이(평균 $14.1{\pm}2.58$세), 그리고 시력안정화 시기에 접근하는 20세 이후(평균 $51.8{\pm}17.51$) 모두 우세안의 시력이 비우세안보다 시력이 높았지만 통계적으로 유의하지 않았다. 근시성 난시에 있어서 우세안의 난시 굴절력 평균값이 비우세안 난시안의 평균값보다 작게 나타났으며, 통계적으로 유의한 결과를 나타내었다(p=0.017<0.05). 결론: 양안 중에서 전체적으로 난시도가 작고 균형 잡힌 눈이 우세안으로 선택될 확률이 높다고 판단된다.

Purpose: When we look at the object, we used the dominant eye mainly. For this reason, a prescription of the dominant eye is an important factor for glasses and contact lenses. This study evaluated visual acuity differences between dominant and nondominant eyes through analyzing refractive power changes in both eyes by the ages. Methods: This study was performed to investigate the relationship between refractive error and dominant eye which had the superiority in the function of binocular. 186 subjects without ocular disease were examined on the dominant eye. The dominant eye was examined by the Hole-in-the-card test. For the consistency of the measurements, we tested refractive power in three times by the same person. Results: Using SPSS, the relationship between vision and the dominant eye was analyzed. 135 people of the whole subjects have the dominant eye on right. The Number of the non-dominant eye is 51. We were divided into 3 types, the group under the age of 10 that begins to expose environment factor affect on vision (the average age $8.8{\pm}1.18$) and the age group of 10 to 20 that begins to change refractive power in earnest (the average age $14.1{\pm}2.58$) and the group after the age 20 that began to stabilize vision (the average age $51.8{\pm}17.51$). The visual acuity of dominant eye was higher than non-dominant eye in all age groups. Nevertheless, these results were not statistically significant. Mean astigmatism of dominant eye was smaller than the non-dominant eye, and this is significant, statistically (p=0.017<0.05). Conclusions: It is expected that the balanced eye with a lower level of astigmatism has a more possibility become a dominant eye.
