초록

목적: 조도변화가 시기능에 미치는 영향을 알아보고자 하였다. 방법: 평균나이 $23.93{\pm}1.59$세 40명(남 21, 여 19)을 대상으로 시표면 조도를 5, 50, 200, 500 및 800 lx로 조정하여 각 조도 상태에서 조절력, 폭주근점, 원거리 및 근거리 사위, 원거리 및 근거리 융합버전스, 상대조절력, 조절래그를 측정하였다. 결과: 시표면의 조도가 감소함에 따라 조절력은 유의하게 감소하였고(p<0.05), 조절래그는 감소하였고, 폭주근점은 멀어졌으며, 수평사위는 내편위의 경향을 보였다. 음성융합버전스는 조도가 감소함에 따라 분리점과 회복점이 감소하는 경향을 보인 반면 양성융합버전스는 분리점이 증가하는 경향을 보였다. 음성 및 양성상대조절력의 경우 조도가 감소함에 따라 유의한(p<0.05) 감소를 보였다. 결론: 임상현장에서 시기능 검사는 환자의 생활환경 및 직업 등을 고려한 적절한 조도 수준에서 수행되어야 할 것으로 사료된다.

Purpose: This study was performed in order to figure out the influence of illumination on visual function. Methods: 40 adults (male 21, female 19) of average age $23.93{\pm}1.59$ years were participated in this study. The test chart surface illumination was adjusted to 5, 50, 200, 500 and 800 lx, and then amplitude of accommodation, near point of convergence, far and near distance phoria, far and near distance fusional vergence, relative accommodation, and accommodation lag were measured at each illumination condition. Results: As illumination intensity of test chart was reduced, amplitude of accommodation was significantly decreased (p<0.05), accommodation lag was also decreased, near point of convergence was receded, and horizontal phoria showed a tendency of esodeviation. In the case of negative fusional vergence, with reduction of illumination intensity, the break point and the recovery point were decreased but in the case of positive fusional vergence, the break point was increased. The negative and positive relative accommodation were significantly decreased (p<0.05) with reduction of illumination intensity. Conclusions: In clinical practice, visual functional test should be performed under condition of adequate illumination level through patient's living environment and job.
