Orbscan Topography System 및 A - scan Ultrasonography로 전 방깊 이 훌 측정 하 여 두 기 기 의 신 뢰 도를 평 가하고， A - scan Ultrasonography률 gold standard로 간주 하여 Orbscan Topography System으로 측정한 전방깊이 값의 정확도를 분석하였다. 20안올 대 상으로 Orbscan Topography System 및 A - scan Ultrasonography롤 이 용 하여 측정한 test 와 retest 차이에 대한 평균값은 각각 0.030 :t 0.150 mm와 0.016:t 0.065mm 였다. 또한 54안을 대상으로 Orbscan Topography System과 A - scan Ultrasonography로 측정한 전방깊이 값의 평균은 각각 3.200:t 0.302 mm와 2.999:t 0.239mm로， Orbscan Topography System 측정 값이 더 높았으며 (t = 10.α)3， p<O.αX)1)， 두 기기의 측정값 사이에 높은 상관관계가 있었다 (r = 0.824, p<O.OOül). Orbscan Topography System 측정값을 A - scan Ultrasonography 측정값과 직접 비교하기 위해서는 환산공식이 필요하다.
The study assessed repeatability of the anterior charnber depth estimates provided by the Orbscan Topography System. and an A - scan U1trasonoragpy, and assessed comparability of the Orbscan Topography Systme and A - scan Ultra -sonography as gold standard. In the 20 eyes, mean of the differences of Test and Retest in anterior charnber depth measured by Orbscan Topography System and A - scan Ultrasonography were 0.03O:t 0.150 mm and 0.016 mm, respectively. In 54 eyes, mean of ACD measured by Orbscan Topography System and A - scan Ultrasonography were 3.2oo:t 0.302 mm and 2.999:t 0.239 mm, respectively. Mean ACD values measured by Orbscan Topography was more deeper than that of measured by A - scan Ultrasonography(t=10.oo3, p<O.α)()1) ， and the correlation coefficient between Orbscan and ultrasonography was 0.824(p <0.0001). Therefore, there was required conversion factor when ACD values measured by Orbscan Topography System was directly compared to that of measured by A - scan Ultrasonography.
