        Purpose : To evaluate changes and correlations of ACA, ACD and ACV by ages and refractive errors using Pentacam in Korean undergraduate students and elderly people. Methods : 52 healthy eyes(male : 27, female : 25) of undergraduate students and 38 healthy eyes of elderly people were recruited(average age : 22.52148±0.62435 years). We measured anterior chamber angle(ACA), anterior chamber depth(ACD), anterior chamber volume using Pentacam(Oculus Co.) and spherical equivalent refractive errors(SE) by subjective re(raction. 52 undergraduate students were classified into emmetropes group(-0.75-+0.750) and myopes group(> -1.000). The averages SE of emmetropes and myopes groups were -0.28333±0.32550 and -3.12162±1.51110 respectively. Results : The average ACD. ACA and ACV were 3.18906±0.20435 mm, 40.53019± 5.10831°, 193.49057±28.45213 mm3 respectively in undergraduate students group and 2.76158±0.42819 mm. 32.63947±5.84385°. 134.21053±28.94091 mm respectively in elderly group. lncreasing age was associate with reduced ACA. ACD and ACV. and there was no correlation by sex. There showed significant differences between ACD and ACA(t = - 47.64. p = 0.00). between ACO and ACV(t = -38.78. p = 0.00) and between ACV and ACA(t = 39.48. p = 0.00) l = - 50.61 p = 0.00. t = - 49.27 p = 0.00. t = 38.81 p = 0.00 respectively in undergraduate students group and t = -31.43 p = 0.00. t = -28.00 p = 0.00. t = 21.20 p = 0.00 respectively in elderl y group. Excellent correlation was found between ACD and ACV in undergraduate students group(R = 0.89). There showed significant differences in ACO and ACV(t = -2.25 p = 0.03. t = -2.24, p = 0.29 respectively), however no significant difference in ACA(t = -1.59 p = 0.12) between emmetopes group and myopes group. Conclusion : lncreasing age was associate with reduced ACA. ACO and ACV ; ACA was changed from grade 4 to grade 3 by Shaffer's classification. There showed significant differences between ACD and ACV. between ACD and ACA, between ACV and ACA Especially excellent correlation was found between ACD and ACV in undergraduate students group(R = 0.89). There showed significant differences in ACO and ACV, however no significant difference in ACA between emmetropes group and myopes group.

        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.
