目的评估Sirius、Orbscan Ⅱ及超声测厚仪测量中央角膜厚度(CCT)的差异和一致性.方法对250例(500只眼)近视眼患者,依次采用Sirius、Orbscan Ⅱ及USP测量CCT.结果 Siri-US、OrbscanⅡ及USP测得的平均CCT分别为(525.7±36.7) μm、(515.5±44.1)μm、(529.1±35.8)μm.3种仪器测量CCT高度相关:Sirius与USP(r=0.964,P＜0.001)、Orbscan Ⅱ与USP(r=0.932,P ＜0.001)、Sirius与Orbscan Ⅱ(r=0.940,P＜0.001).CCT的差值均数(包括一致性界限的上线和下线)为Sirius与USP (3.4±9.8)μm、(-15.7,22.6)、Orbscan Ⅱ与USP (13.6±16.9) μm(-19.4,46.7)、Sirius与Orbscan Ⅱ(10.2土15.8)μm(-20.8,41.2).结论与USP相比,Sirius与Orbscan Ⅱ低估了中央角膜厚度.与Orbscan Ⅱ相比,Sirius与USP有较好的相关性和一致性.3种仪器测量CCT不可互相替换.Sirius可能逐渐取代角膜厚度测量的金标准.

Objective To assess the difference and agreement of central corneal thickness measurements between Sirius,Orbscan Ⅱ,and ultrasound pachymetry (USP).Methods On 250 myopic patients (500 eyes),the central corneal thickness was measured using Sirius,Orbscan Ⅱ and ultrasound pachymetry in turn.Results The mean measurements of average central corneal thickness by Sirius,Orbscan Ⅱ,and USP were 525.7±36.7μm,515.5±44.1μm and 529.1±35.8μm respectively.There was high correlation between the three instruments:Sirius with USP (r =0.964,P ＜0.001),Orbscan Ⅱ with USP (r =0.932,P ＜0.001) and Sirius with Orbscan Ⅱ (r =0.940,P ＜0.001).The mean differences (and upper/lower LOA) for central corneal thickness measurements were 3.4±9.8μm (-15.7,22.6) between Sirius and USP, 13.6±16.9μm (-19.4,46.7) between Orbscan Ⅱ and USP,and 10.2±15.8μm (-20.8,41.2) between Sirius and Orbscan Ⅱ.Conclusions Sirius and Orbscan Ⅱ underestimate corneal thickness compared with that measured with USP.Sirius has better correlation and agreement with the gold standard USP,as compared with Orbscan Ⅱ.The three instruments can not be used interchangeably for measuring central corneal thickness.Sirius eventually may replace USP as the gold standard for corneal pachymetry.
