目的比较两种眼前段检查仪 Pentacam 和 Orbscan I 测量前房深度(ACD)、角膜缘白到白距离(WTW)的差异,分析二者的一致性,为临床应用提供依据.方法前瞻性临床研究.近视患者72例(144眼),分别使用 Pentacam 和 Orbscan I 测量.两种仪器检测数据差异采用配对 t 检验,数据的相关性采用 Pearson 相关分析.结果72例等效球镜为-2.0~-14.0 D,平均-6.40±2.38D,Pentacam 和 Orbscan I 测量 ACD 的平均值分别为3.22±0.255mm 和3.13±0.253mm,差异具有统计学意义(t=19.172,p=0.000)；测量 WTW 的平均值分别为11.66±0.340mm 和11.46±0.306mm,差异具有统计学意义(t=20.570,p=0.000).两种仪器测量的前房深度和角膜缘白到白距离均具有相关性(r=0.975,p=0.000；r=0.941,p=0.000)结论 Pentacam 和 Orbscan I 测量眼部无器质性疾病人群的前房深度和角膜缘白到白距离具有较好的相关性,Pentacam 的测量结果略大于 Orbscan I.%Objective To compare the results of anterior chamber depth and cornea diameter measured by Pentacam and Orbscan I. Methods A clinical prospective studies, the anterior chamber depth and cornea diameter of 72 myopia patients(144 eyes) were measured by Pentacam and Orbscan I respectively. The difference of data measured by two instruments was analyzed by paried t- test, and the relative was analyzed by Pearson correlation analysis.Results The equivalent power of 144 eyes was -2.0 ~ -14.0D, the average was-6.40 ± 2.38D(mean ± SD). The value of anterior chamber depth measured by Pentacam was 3.22 ± 0.255mm, measured by Orbscan I was 3.13 ± 0.253mm, there was significant difference between them (t=19.172,p=0.000) and significant correlation between them (r=0.975,p=0.000). The value of cornea diameter measured by Pentacam was 11.66 ± 0.340mm, measured by Orbscan I was 11.46 ± 0.306mm, there was significant difference between them (t=20.570,p=0.000) and significant correlation between them (r=0.941,p=0.000).Conclusions There were significant correlations either the results of anterior chamber depth or cornea diameter measured by Pentacam and Orbscan I . However, the results of Pentacam were slightly bigger than them from Orbscan I.
