Abstract:
UNASSIGNED: Multidiagnostic systems have recently appeared on the market. Knowledge of the repeatability and validity of any instrument is mandatory before its introduction in clinical practice.
UNASSIGNED: The aim of this work is to examine the intrasession repeatability of anterior pole measurements provided by the multidiagnostic device Wave Analyzer Medica 700 (WAM700) and agreement with Pentacam measurements in normal eyes.
UNASSIGNED: In the right eyes of 113 participants, three repeat measurements of central keratometry, central corneal thickness, anterior chamber depth and corneal eccentricity were made with the WAM700 and Pentacam in random order. Intrasession repeatability and agreement were determined.
UNASSIGNED: Employing WAM700, intrasession repeatability for keratometry, central corneal thickness and anterior chamber depth was good (ICCs ≥ 0.992; CV 0.48-0.98%), yet worse than the values obtained for the Pentacam (ICCs ≥ 0.998; CV 0-0.33%). WAM700 showed excellent intrasession repeatability when used to measure the anterior chamber depth (Sw 0.03 mm). However, the repeatability of this device was inferior for central corneal thickness (Sw 4.24 μm) and keratometry measurements (Sw < 0.21 D) and was poor for corneal eccentricity (Sw 0.07; ICC 0.908; CV 14.58%). Agreement between WAM700 and Pentacam showed a high ICC for the keratometry measurements, central corneal thickness and anterior chamber depth (>0.972) but lower for corneal eccentricity (ICC 0.762).
UNASSIGNED: In healthy eyes, the WAM700 multidiagnostic device showed good intrasession repeatability for keratometry, central corneal thickness and anterior chamber depth measurements. Agreement between WAM700 and Pentacam was good for the anterior chamber depth measurement. However, these instruments cannot be considered interchangeable for keratometry, central corneal thickness and eccentricity readings.
摘要:
多诊断系统最近出现在市场上。在临床实践中引入任何仪器之前,必须了解其可重复性和有效性。
这项工作的目的是检查多诊断设备WaveAnalyzerMedica700(WAM700)提供的前极测量的内进可重复性,并与正常眼中的Pentacam测量结果一致。
在113名参与者的右眼中,中央角膜曲率测量的三次重复测量,中央角膜厚度,使用WAM700和Pentacam按随机顺序进行前房深度和角膜偏心度。确定了侵入的可重复性和一致性。
采用WAM700,角膜曲率测量的内进可重复性,中央角膜厚度和前房深度良好(ICC≥0.992;CV0.48-0.98%),但比Pentacam获得的值更差(ICC≥0.998;CV0-0.33%)。WAM700在用于测量前房深度(Sw0.03mm)时显示出出色的内进可重复性。然而,该装置的可重复性在中央角膜厚度(Sw4.24μm)和角膜曲率测量(Sw<0.21D)方面较差,而在角膜偏心率方面较差(Sw0.07;ICC0.908;CV14.58%).WAM700和Pentacam之间的协议显示,角膜曲率测量的ICC很高,中央角膜厚度和前房深度(>0.972),但角膜偏心度较低(ICC0.762)。
在健康的眼睛中,WAM700多重诊断设备显示出良好的角膜曲率测量的内进可重复性,中央角膜厚度和前房深度测量。WAM700和Pentacam之间的协议对于前房深度测量很好。然而,这些仪器不能被认为是角膜曲率测量的可互换的,中央角膜厚度和偏心度读数。
