서로 다른 세 가지 기기로 측정한 중심각막두께 및 전방깊이의 비교

Comparison of Central Corneal Thickness and Anterior Chamber Depth Measured Using Three Different Devices

목적: Galilei™ (Ziemer, Port, Switzerland)와 Pentacam？？ (Oculus, Wetzlar, Germany), Lenstar？？ (Haag-Streit, Koeniz, Switzerland)로 측정한 중심각막두께와 전방깊이의 측정치를 비교하고, 일치도를 분석하고자 한다. 대상과 방법: 정상 성인 25명의 47안을 대상으로 세 기기를 이용하여 측정한 중심각막두께와 전방깊이를 비교하였다. 결과: Galilei™, Pentacam？？, Lenstar？潁？ 이용하여 측정한 중심각막두께는 각각 552.6 ± 29.41 μm, 543.9 ± 30.50 μm, 537.5 ±30.26 μm였고, 측정치 간에 높은 상관관계를 보였으나(r＞0.9, p＜0.001), 통계적으로 유의한 차이를 보였다(p＜0.001). 전방깊이는 Galilei™가 3.23 ± 0.360 mm, Pentacam？瑛？ 3.22 ± 0.403 mm, Lenstar？怜？ 3.19 ± 0.367 mm였고, 측정치 간에 높은 상관관계를 보였으나(r＞0.9, p＜0.001), 통계적으로 유의한 차이를 보였다(p=0.034). 95% 일치도 범위는 Galilei™와 Pentacam？？, Pentacam？怜？ Lenstar？？, Lenstar？玲？ Galilei™ 사이에서 중심각막두께는 31.95 μm, 44.76 μm, 46.57 μm, 전방깊이는 0.46 mm, 0.32 mm, 0.28 mm였다. 결론: 세 기기로 측정한 중심각막두께 및 전방깊이는 상관성이 높으나, 측정값에 차이를 보이고 일치도가 낮아 서로 대치하여 사용할 수 없을 것으로 생각한다. <대한안과학회지 2015;56(5):694-701>

Purpose: To compare measurements of central corneal thickness (CCT) and anterior chamber depth (ACD) obtained using Galilei™, Pentacam？？ (Oculus, Wetzlar, Germany) and Lenstar？？ (Haag-Streit, Koeniz, Switzerland) and analyze the measure-ment agreements. Methods: CCT and ACD were measured using Galilei™, Pentacam？？ and Lenstar？？ in 47 eyes of 25 healthy subjects. The meas-urements were compared among the 3 devices. Results: The average CCT measurements using Galilei™, Pentacam？？ and Lenstar？？ were 552.6 ± 29.41 μm, 543.9 ± 30.50 μm and 537.5 ± 30.26 μm, respectively. The measurements significantly correlated with each other (r > 0.9, p < 0.001), but were stat-istically significantly different (p < 0.001). The average ACD measurements using Galilei™, Pentacam？？ and Lenstar？？ were 3.23 ± 0.360 mm, 3.22 ± 0.403 mm and 3.19 ± 0.367 mm, respectively. The measurements significantly correlated with each other (r > 0.9, p < 0.001), but were statistically significantly different (p = 0.034). The CCT 95% limits of agreement (LoA) between Galilei™ and Pentacam？？, Pentacam？？ and Lenstar？？ and Lenstar？？ and Galilei™ were 31.95 μm, 44.76 μm and 46.57 μm, respectively and 95% ACD LoA were 0.46 mm, 0.32 mm and 0.28 mm, respectively. Conclusions: CCT and ACD measured using the 3 devices were highly correlated with each other but the measurements were statistically different. Therefore, the measurements were not interchangeable and these differences should be considered in clin-ical use. J Korean Ophthalmol Soc 2015;56(5):694-701
