摘要
目的对有晶状体眼后房型人工晶状体（PPC-ICL）植入术后患者应用三维眼前节全景分析仪（Pentacam）与前节光学相干断层扫描仪（AS-OCT）测量拱高及其他眼前节参数，分析2种仪器的差异性和一致性。方法横断面研究。连续选取50例（100眼）PPC—ICL植入术术后复查患者，分别应用Pentacam和前节OCT测量眼前节参数。采用配对样本t检验及Bland-Ahman图法对二者差异性和一致性进行统计学分析。结果Pentacam测得拱高值为（353．8±124．0）μm，前节OCT测得拱高值为（536．2±150．8）μm，两者差异有统计学意义（t=27．92，P〈0．05），两者呈高度正相关性（r=0．905，P〈0．05），Pentacam测得拱高比前节OCT测得拱高低（182．4±65．3）μm，其差值95％一致性区间为54．3～310．5μm。结论Pentacam与前节OCT均能为我们提供拱高值，Pentacam测量值显著低于前节OCT测量值，在临床工作中应该综合分析。
Objective To compare vault and other biometric measurements obtained after Collamer lens （PPC-ICL） implantation using a Pentacam anterior segment system and an anterior segment optical coherence tomography system （AS-OCT）. Methods In this cross-sectional study, vault and other biometrie were was measured in 100 eyes of 50 patients after Collamer lens （PPC-ICL） implantation using a Pentaeam and AS-OCT. The statisitical significance of the difference between the measurements was evaluated by a paired t-test and consistency was assessed by Bland-Altman analysis. Results The mean vault measured by Pentacam and AS-OCT was 353.8±124.0 μm and 536.2±150.8 μm （t= 27.92, P〈0.05） with a significant positive relationship （r=0.905, P〈0.05）. There was a 95% level of consistent interval for the difference in interval width （54.3-310.5 μm）. Conclusion The measurements obtaind by Pentaeam was much lower than AS-OCT. The difference between the measurements of the vault obtained by the two instruments should be considered and accurately evaluated.
