目的:评价Pentacam眼前节分析仪和Keratron Scout角膜地形图仪测量瞳孔偏移量(pupillary offset)的差异和一致性。

     方法:随机选取2017-11/2018-02在我院行准分子激光原位角膜磨镶术(LASIK)的患者311例604眼。术前应用Pentacam眼前节分析仪和Keratron Scout角膜地形图仪测量患者瞳孔偏移量,比较两种仪器测量结果的差异性和一致性。

     结果:Pentacam眼前节分析仪和Keratron Scout角膜地形图仪测量的右眼、左眼、双眼总的offset值均有差异(P<0.05)。两种仪器测量的右眼、左眼、双眼offset轴向均无差异(P>0.05)。两种仪器测量的右眼offset值、offset轴向95%一致性界线(LoA)分别为-0.11~0.19mm、-157.01°~135.35°。左眼offset值、offset轴向95% LoA分别为-0.12~0.18mm、-150.16°~158.22°。双眼offset值、offset轴向95%LoA分别为-0.11~0.19mm、-154.30°~147.10°。

     结论:Pentacam眼前节分析仪测量的瞳孔偏移量比Keratron Scout角膜地形图仪的测量值小,差异在临床可以接受的范围内。两种仪器均可以获得准确的瞳孔偏移量数据,可相互参考、校正和补充。

Abstract:
      AIM: To evaluate the difference and consistency of pupillary offset measured by the Pentacam anterior segment analyzer and Keratron Scout corneal topographer.

     METHODS: Three hundred and eleven patients(604 eyes)who underwent excimer laser in situ keratomileusis from November 2017 to February 2018 were randomly selected. Before surgery, the pupillary offset values were measured by Pentacam and Keratron, and the differences and consistency of the values between the two instruments were compared.

     RESULTS: The pupillary offset values of the right eyes, left eyes, and both eyes between Pentacam and Keratron were statistically different(P<0.05). There were no significant statistical differences in the offset orientations of right eyes, left eyes and both eyes between the two instruments(P>0.05). The 95% consistent line(LoA)of offset value and offset orientation in the right eyes, left eyes and both eyes between the two instruments were -0.11-0.19mm and -157.01°-135.35°, -0.12-0.18mm and -150.16°-158.22°, -0.11-0.19mm and -154.30°-147.10°, respectively.

     CONCLUSION: The pupillary offset measured by the Pentacam was smaller than that measured by the Keratron, but the difference was within the clinically acceptable range. The accurate pupillary offset can be obtained, and be the mutual reference, correction and supplement in the both instruments.
