Abstract

Purpose: The study was to analyze the correlation between kinetic visual acuity (KVA), visual acuity(static visual angle, SVA) and contrast sensitivity. Methods: Ninety-nine undergraduate students studying Ophthalmic Optics were fully corrected by the Topcon CV-3000 Phoropter. The contrast sensitivity was measured for the participants under the photopic condition ($100cd/m^2$) with Vector Vision CSV-1000E at 2.5 meter, while KVA was measured with KOWA AS-4A. The participants were classified into three groups L, M and H depending on the KVA (0.1~0.3, 0.31~0.6 and greater than 0.61, respectively) and were analyzed whether there was the correlation between the contrast sensitivity, visual acuity and refractive error. Results: The KVA was correlated with the contrast sensitivity for 3 cpd (r=0.26), for 6 cpd (r=0.48), for 12 cpd (r=0.38) and 18 cpd (r=0.47). Except for the low frequency of 3 cpd, they all were higher than the one of the SVA and the KVA (r = -0.37). The contrast sensitivity for 3, 6, 12 and 18 cpd was 59.41, 92.22, 38.41 and 14.39 in the group L, respectively. The contrast sensitivity in the group M was 66.03, 108.78, 53.51 and 19.20 and the one in the group H was 70.90, 146.10, 62.90 and 25.33 for 3, 6, 12 and 18 cpd, respectively. Conclusions: The correlation of the contrast sensitivity and the KVA was higher than the one of the contrast sensitivity and the SVA. It can be assumed that the contrast sensitivity will be high if the KVA is high, except for the case for low spatial frequency.

목적: 동적시력(Kinetic visual acuity, KVA), 대비감도(Contrast sensitivity), 정지시력(정지시각 Static visual angle, SVA) 등의 상관관계를 분석해 보고자 하였다. 방법: 안경광학과 재학생 99명(남 51명, 여 48명)을 대상으로 Topcon CV-3000 포롭터를 이용하여 완전교정 후 명소시($100cd/m^2$)상태에서 Vector Vision CSV-1000E를 이용하여 2.5 m 거리에서 대비감도를 측정하였다. 또한 KVA 측정장치(KOWA AS-4A)을 이용하여 동적시력을 측정하였다. KVA 정도에 따라, 0.1~0.3 L그룹, 0.31~0.60 M그룹, 0.61 이상을 H그룹으로 분류하고 대비감도, 정지시각, 굴절이상량 등의 상관관계를 분석하였다. 결과: KVA와 대비감도의 상관성은 3 cpd r=0.26, 6 cpd r = 0.48, 12 cpd r=0.38, 18 cpd r=0.47로 저주파수인 3 cpd를 제외하고, 모두 KVA와 SVA의 상관성 r = -0.37 보다 높았다. 주파수별 대비감도는 3, 6, 12, 18 cpd에서 각각 L그룹은 59.41, 92.22, 38.41, 14.39, M그룹은 66.03, 108.78, 53.51, 19.20, H그룹은 70.90, 146.10, 62.90, 25.33이였다. 결론: KVA와 대비감도의 상관성이 SVA보다 높으며, KVA가 높은 경우 저주파수 이외에서는 대체로 대비감도가 높은 것을 알 수 있었다.
