摘　　要：目的 比较Pentacam三维眼前节分析诊断系统、IOL-Master眼科光学生物测量仪及A型超声测量前房深度的差异,并对三种测量结果进行一致性评价.方法 随机抽取屈光手术前的近视眼患者63例（126只眼）,受检者年龄平均为（25.09±1.29）岁,等效球镜屈光度平均为（-5.19±2.04）D.应用Pentacam、IOL-Master及A型超声三种仪器分别对双眼中央前房深度进行测量,并对检查结果采用单因素方差分析.结果 Pentacam、IOL-Master及A型超声测量前房深度的平均值分别为（3.718±0.282）mm、（3.723±0.295）mm和（3.584±0.261）mm.Pentacam与IOL-Master之间有较好的一致性,比较没有统计学意义（P＞0.05）.而A型超声与Pentacam、IOL-Master之间的平均值差别分别为（0.133±0.025）mm（P＜0.05）、（0.139±0.020）mn（P＜0.05）,有统计学意义.结论 三种仪器在进行前房深度测量时,从总体上讲,Pentacam与IOL-Master测量值较A型超声数值偏大,Pentacam与IOL-Master前房深度值一致性较好,可相互替代,而A型超声与Pentacam、IOL-Master测量结果有显著性差异,完全相互替代需慎重.Objective To explore the differences of central anterior chamber depth （ACD） determined by Pentacam, IOL-Master and A-Scan and to evaluate the agreement of the three instruments. Methods A total of 126 eyes of 63 subjects aged （25.09 ± 1.29） with spherical Equivalent-（- 5.19 ± 2.04）D were determined ACD on both eyes with Pentacam, IOLMaster and A-Scan. Data were used to analyze the difference of ACD between the three methods. Results The mean value of ACD was （3.718± 0.282） mm for Pentacam and （3.723± 0.295） mm for IOL-Master and （3.584± 0.261） mm for A-Scan. Pentacam and IOL-Master showed a high corre lation and there was no significantly difference. Compared the A-Scan with the Pentacam and IOL-Master measurements significantly misestimate ACD by a mean of （0.133± 0.025） mm （P 〈0.05）, （0.139±0.020） mm （P 〈0.05）,respectively and there was significantly significant difference. Conclusions Pentacam and IOL-Master can be interchanged for ACD, but A-Scan and Pentacam or IOL-Master cannot be interchanged fully.
