목적: 약시가 자세 조절 능력에 미치는 영향을 평가하고, 약시 환자의 자세 안정성에 영향을 미치는 시각 기능의 역할을 실증적으로 분석하기 위해 수행되었다. 방법: 44명을 대상으로 진행되었으며, 정상군 20명과 약시군 24명으 로 구분하여 시각적 능력 및 자세 안정성을 평가하였다. 자세 안정성은 BTrackS 균형측정기기를 사용하여 측정하 였다. 결과: 약시군은 정상군에 비해 통계적으로 유의미하게 높은 신체 흔들림을 보였으며(p<0.05), 특히 눈을 뜬 상 태에서 측정된 경로 길이에서 큰 차이를 나타냈다. 또한, 연령이 증가함에 따라 신체 흔들림이 감소하는 경향을 보 였으며(p<0.05), 입체시가 저하된 대상자에서 자세 조절 능력이 현저히 저하되었다(p<0.05). 결론: 약시는 자세 조절 능력에 부정적인 영향을 미치며, 시각적 정보가 자세 안정성 유지에 중요한 역할을 함을 확인하였다.

Purpose: This study was conducted to evaluate the impact of amblyopia on postural control abilities and to analyze the role of visual function in influencing the postural stability of patients with amblyopia empirically. Methods: The study involved 44 participants, divided into 20 in the normal group and 24 in the amblyopic group. Participants’ visual capabilities and postural stability were analyzed. Postural stability was measured using the BTrackS balance assessment system. Results: The amblyopic group exhibited significantly higher body sway than did the normal group (p<0.05), particularly in the path length measured while the eyes were open. Additionally, a trend of decreasing body sway with increasing age was noted (p<0.05), and a significant decline in postural control abilities was observed in participants with reduced stereopsis (p<0.05). Conclusions: Amblyopia negatively affects postural control abilities. Visual information plays a crucial role in maintaining postural stability.
